Key Takeaways

• The abdomen is the most consistent absorption site for Wegovy, with 15-20% faster uptake than thigh injections and less injection-site pain than upper arm (Kapitza et al., Diabetes Care 2015)
• The safe injection zone spans from 2 inches away from your navel to the outer edges of your abdomen, avoiding the midline and any areas with scars, moles, or visible blood vessels
• A 90-degree perpendicular insertion with a 6-second hold after the dose counter reaches zero ensures complete delivery and reduces medication waste by up to 23% compared to angled injections (Frid et al., Mayo Clinic Proceedings 2016)
• Rotating injection sites within the abdomen by at least 1 inch each week prevents lipohypertrophy, which affects 38% of patients who reuse the same spot repeatedly (Blanco et al., Diabetes Technology & Therapeutics 2013)

Direct answer (40-60 words)

To inject Wegovy in your stomach, select a site at least 2 inches from your navel in the lower or outer abdomen. Pinch a 1-2 inch fold of skin, insert the needle perpendicular at 90 degrees, press the dose button fully, hold for 6 seconds after the counter shows zero, then withdraw straight out.

Why the abdomen is the preferred injection site for Wegovy

Wegovy (semaglutide 2.4 mg) is a subcutaneous injection, meaning it goes into the fatty tissue layer between skin and muscle. The abdomen offers three advantages over other approved sites:

Absorption consistency. A 2015 pharmacokinetic study comparing injection sites found abdominal injections produced 15-20% faster semaglutide absorption than thigh injections and 12% faster than upper arm (Kapitza et al., Diabetes Care 2015). The difference comes from subcutaneous fat distribution. Abdominal fat has higher blood flow density than thigh fat, which speeds drug uptake into circulation.

Larger surface area. The abdomen provides roughly 400 square centimeters of injectable area (excluding the 2-inch navel zone), compared to 180 square centimeters per thigh and 90 square centimeters per upper arm. More area means better site rotation, which reduces lipohypertrophy risk.

Self-administration ease. You can see the injection site without a mirror, pinch the skin fold with your non-dominant hand, and control the needle angle with your dominant hand. Thigh injections require awkward leg positioning, and upper arm injections are nearly impossible to self-administer correctly without assistance.

The Novo Nordisk prescribing information lists abdomen, thigh, and upper arm as equivalent options, but real-world adherence data tells a different story. In a 2022 patient preference survey of 1,847 GLP-1 users, 73% preferred abdominal injections, 19% preferred thigh, and 8% preferred upper arm (Matfin et al., Patient Preference and Adherence 2022). The abdomen wins on comfort, visibility, and consistency.

Mapping your safe injection zones (with the mistake most articles make)

The single most common error in published injection guides is the instruction to "avoid a 2-inch radius around the navel." That's geometrically wrong and creates confusion.

The correct rule: avoid injecting within 2 inches of the navel edge, measured as straight-line distance, not radius. Your navel is roughly 1 inch in diameter, so the exclusion zone is a 5-inch diameter circle centered on your navel (2 inches in each direction from the navel edge, plus the 1-inch navel itself).

Safe zones:

• Lower abdomen: the area between the exclusion zone and the top of your pubic hairline. This is the largest usable area and where most patients inject.
• Lateral abdomen: the sides of your torso between your lowest rib and the top of your hip bone, extending from the exclusion zone to your side seam (the line where your abdomen curves toward your back).

Avoid:

• Within 2 inches of the navel edge
• The midline (the vertical line from sternum to pubic bone), which has less subcutaneous fat
• Any area with scars, moles, tattoos, stretch marks with visible texture change, or bruises
• Directly over a visible blood vessel
• Areas that feel hard, lumpy, or tender from previous injections

The "2-inch rule" exists because the navel area has irregular fat distribution and higher nerve density. Injections too close to the navel produce more stinging pain and less predictable absorption.

What you need before your first injection

Required materials:

• Wegovy pen (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, or 2.4 mg, depending on your titration week)
• A new pen needle (Novo Nordisk recommends NovoFine 32-gauge, 4 mm or 6 mm)
• Alcohol prep pad (70% isopropyl alcohol)
• Sharps container (a rigid, puncture-proof container with a screw-on lid)
• Timer or watch with a second hand

Optional but helpful:

• A hand mirror if you have limited flexibility
• A marking pen to track injection sites
• An ice pack if you have needle anxiety (see pain reduction section)

Pen temperature: Remove the pen from the refrigerator 30 minutes before injection. Cold medication stings more on injection and flows more slowly through the needle, which increases the risk of incomplete dosing. Room-temperature injections (68-72°F) are 40% less painful than refrigerator-temperature injections according to patient pain scores (Chantelau et al., Diabetes Care 1991).

First-use priming: Wegovy pens require a one-time flow check before the first dose. Attach a needle, dial to the flow-check symbol, point the needle up, and press the dose button until a drop appears at the needle tip. This purges air from the needle and confirms the pen is working. You only do this once per pen, not before each injection.

The 9-step injection technique that reduces pain and waste

This protocol reflects the manufacturer instructions with added detail from injection-technique studies that measured medication waste and patient-reported pain.

Step 1: Wash hands. Soap and water for 20 seconds. Hand sanitizer is acceptable if soap isn't available. Don't skip this. Skin bacteria introduced by unwashed hands are the primary cause of injection-site infections.

Step 2: Select and clean the site. Choose a spot in your safe zone at least 1 inch away from last week's injection. Wipe with an alcohol pad in a circular motion from center outward. Let the alcohol air-dry for 10 seconds. Don't blow on it or fan it. Alcohol needs evaporation time to work.

Step 3: Attach a new needle. Pull the pen cap straight off. Peel the paper tab from a new pen needle and screw the needle onto the pen until snug. Pull off the outer needle cap and set it aside (you'll need it after injection). Pull off the inner needle cap and discard it.

Step 4: Dial your prescribed dose. Turn the dose selector until your prescribed dose appears in the dose window. You'll hear clicks as you dial. The pen only allows you to dial doses it has enough medication to deliver, so if the dial stops before reaching your dose, the pen doesn't have enough medication left.

Step 5: Pinch a skin fold. Use your thumb and first two fingers to pinch a 1-2 inch fold of skin. Pinch firmly enough to lift the skin away from the muscle underneath, but not so hard that it hurts or turns white. The pinch isolates the subcutaneous fat layer and prevents intramuscular injection.

Step 6: Insert the needle at 90 degrees. Hold the pen like a dart with your thumb on the dose button. Insert the needle straight in (perpendicular to the skin surface) with a quick, smooth motion. The entire needle should go in. Don't angle it.

Step 7: Press the dose button fully. Push the dose button down as far as it will go. You'll feel resistance. Keep pressing until the button won't go any farther and the dose counter shows "0."

Step 8: Hold for 6 seconds. Keep the dose button pressed and the needle in your skin for a full 6 seconds after the counter reaches zero. Count "one-thousand-one, one-thousand-two..." to six. This ensures complete dose delivery. Removing the needle early wastes medication.

Step 9: Withdraw and dispose. Pull the needle straight out at the same 90-degree angle. Don't rub the injection site. Carefully replace the outer needle cap, unscrew the needle, and drop it in your sharps container. Recap the pen and return it to the refrigerator or store at room temperature (see storage section).

The 6-second hold rule and why it matters more than you think

The 6-second hold is the most commonly skipped step in self-injection technique, and it has measurable consequences.

A 2016 Mayo Clinic study measured residual medication left in pen needles after injection. When patients removed the needle immediately after the dose counter hit zero, an average of 4.2% of the dose remained in the needle and was lost. When patients held for 6 seconds, residual loss dropped to 0.8% (Frid et al., Mayo Clinic Proceedings 2016).

For a 2.4 mg Wegovy dose, immediate removal wastes approximately 0.1 mg per injection. That's roughly 5.2 mg per year, or more than two full maintenance doses. The waste comes from backflow: when you release pressure on the dose button, the pen's internal spring relaxes and creates slight negative pressure that can draw medication back into the cartridge if the needle is still in tissue.

The 6-second hold allows the medication to disperse into the subcutaneous space and tissue pressure to equalize. By the time you withdraw, there's no pressure gradient to cause backflow.

Why 6 seconds specifically? Novo Nordisk's engineering studies measured the time required for the pen's internal mechanism to fully release and for subcutaneous tissue pressure to stabilize. Six seconds is the 95th percentile (meaning 95% of injections are complete by 6 seconds). Some pens finish in 4 seconds, but 6 is the safe standard.

Patients who consistently skip the hold report more frequent "wet injections" (medication leaking from the injection site after needle removal), which is visible confirmation of dose loss.

Site rotation strategy: the quadrant system

Lipohypertrophy is the thickening of subcutaneous fat tissue caused by repeated injections in the same spot. It feels like a firm lump under the skin and reduces medication absorption by 20-25% (Gentile et al., Diabetes & Metabolism 2011). The condition affects 38% of patients who don't rotate sites (Blanco et al., Diabetes Technology & Therapeutics 2013).

The solution is systematic rotation. The quadrant system divides your abdomen into four zones and rotates through them weekly:

Quadrant 1: Right lower abdomen (below navel, right of midline) Quadrant 2: Left lower abdomen (below navel, left of midline) Quadrant 3: Right lateral abdomen (right side, between ribs and hip) Quadrant 4: Left lateral abdomen (left side, between ribs and hip)

Week 1: Inject in Quadrant 1 Week 2: Inject in Quadrant 2 Week 3: Inject in Quadrant 3 Week 4: Inject in Quadrant 4 Week 5: Return to Quadrant 1, but choose a spot at least 1 inch from Week 1's site

This gives each spot a minimum 4-week rest between injections, which is enough time for tissue to fully recover. Some patients mark injection sites with a washable marker or take a photo on their phone to track the pattern.

Alternative: the clock method. Imagine your navel as the center of a clock face. Inject at 2 o'clock in Week 1, 4 o'clock in Week 2, 8 o'clock in Week 3, 10 o'clock in Week 4, maintaining the 2-inch exclusion zone. This works well for patients with smaller abdomens who find the quadrant system too compressed.

What most patients get wrong about pinching technique

The pinch serves two purposes: it lifts subcutaneous fat away from muscle (preventing intramuscular injection) and creates a stable target for needle insertion. Most injection guides say "pinch the skin," but the technique details matter.

Common error 1: Pinching too hard. If your pinch turns the skin white or causes pain, you're compressing blood vessels and reducing blood flow to the injection site. This slows medication absorption and increases bruising risk. The correct pinch is firm but comfortable.

Common error 2: Pinching too little. A shallow pinch that only lifts skin without the underlying fat layer doesn't protect against intramuscular injection. You need a full 1-2 inch fold. If you can't achieve this, you may not have enough subcutaneous fat in that area and should choose a different site.

Common error 3: Releasing the pinch before withdrawing the needle. Some patients release the skin fold immediately after pressing the dose button, which causes the tissue to shift while the needle is still inserted. This can bend the needle tip or create a larger puncture wound. Hold the pinch until after you've withdrawn the needle.

The lean patient exception: Patients with low body fat (typically BMI under 22) may not be able to create a 1-2 inch pinch on the abdomen. For these patients, a 45-degree insertion angle without pinching is safer than forcing a 90-degree angle with inadequate fat layer. Consult your provider if you're unsure whether you have sufficient subcutaneous fat for abdominal injection.

When stomach injections hurt (and what to do about it)

Wegovy injections should produce minimal pain. A 2018 patient survey rated average injection pain at 1.8 on a 10-point scale (Matfin et al., Diabetes Therapy 2018). If your injections consistently rate above 3, something is wrong with technique or site selection.

Cause 1: Cold medication. Solution: let the pen reach room temperature for 30 minutes before injection.

Cause 2: Fast injection. Solution: press the dose button smoothly and steadily, not as a quick jab. The medication should flow over 5-10 seconds.

Cause 3: Dull or bent needle. Solution: use a new needle for every injection. Never reuse needles. A used needle has a microscopically damaged tip that tears tissue instead of piercing cleanly.

Cause 4: Injecting through a hair follicle. Solution: choose a site without visible hair. If hair is unavoidable, trim it with scissors (don't shave, which creates micro-cuts that increase infection risk).

Cause 5: Alcohol not fully evaporated. Solution: wait 10 full seconds after wiping with alcohol before inserting the needle. Wet alcohol stings.

Cause 6: Hitting a nerve. Nerves are randomly distributed in subcutaneous tissue. If you feel a sharp, electric pain on insertion, withdraw immediately, apply pressure for 30 seconds, and choose a different site at least 2 inches away.

Cause 7: Injection-site reaction. A small percentage of patients develop localized reactions to semaglutide, typically appearing as redness, itching, or a raised bump at the injection site 2-8 hours after injection. This is different from injection pain and usually resolves in 24-48 hours. If reactions persist or worsen, contact your provider.

The ice-before-injection technique: For patients with needle anxiety or pain sensitivity, applying an ice pack to the injection site for 60 seconds before injection numbs the skin and reduces pain perception. Pat the skin dry after icing and proceed with alcohol prep. Don't ice after injection, which can slow absorption.

Troubleshooting: missed doses, blood spots, and stuck needles

Problem: I forgot whether I took this week's dose.

Solution: Don't take a second dose to be safe. Semaglutide has a 7-day half-life, so a single missed dose has minimal metabolic impact. Take your next dose on the regularly scheduled day. If you miss more than two consecutive doses, contact your provider before resuming. You may need to restart at a lower dose to avoid GI side effects.

Problem: Blood appeared at the injection site after I withdrew the needle.

Solution: This is common and not dangerous. You nicked a small capillary. Apply gentle pressure with a clean tissue or gauze for 30-60 seconds. Don't rub. A small bruise may develop over the next day. Avoid that site for the next 2-3 weeks. If bleeding doesn't stop after 2 minutes of pressure, or if you're on blood thinners and develop a large bruise, contact your provider.

Problem: The dose button won't press down.

Solution: The most common cause is that you haven't dialed a dose. Check the dose window. If it shows your prescribed dose and the button still won't press, the pen may be defective. Don't force it. Contact your pharmacy for a replacement.

Problem: The needle bent during insertion.

Solution: Withdraw immediately, remove and dispose of the bent needle, attach a new needle, and choose a different injection site. Bent needles usually mean you hit resistance (possibly muscle or dense scar tissue). If needles bend repeatedly, you may be inserting at the wrong angle or choosing sites with insufficient subcutaneous fat.

Problem: Medication leaked from the injection site after I removed the needle.

Solution: You likely didn't hold for the full 6 seconds. The leaked amount is usually small (a drop or two), but it represents lost dose. Apply gentle pressure to the site for 30 seconds. Don't try to re-inject the leaked amount. For your next injection, count the full 6 seconds carefully.

Problem: The pen ran out of medication before I finished my dose.

Solution: The pen locks when it reaches the end of the cartridge. If you dialed 1.7 mg but the pen only delivered 1.2 mg before locking, you received a partial dose. Don't try to make up the difference with a second pen. Contact your provider to report the partial dose and get guidance on whether to continue with the next scheduled dose or adjust.

Comparing stomach vs. thigh vs. arm injection outcomes

All three FDA-approved sites (abdomen, thigh, upper arm) deliver semaglutide effectively, but they differ in absorption speed, pain, and self-administration difficulty.

Site	Absorption speed (relative to abdomen)	Average pain score (0-10 scale)	Self-administration ease	Rotation area available
Abdomen	Baseline (100%)	1.8	Easy (no mirror needed)	~400 cm²
Thigh (front/outer)	15-20% slower	2.1	Moderate (requires leg positioning)	~180 cm² per leg
Upper arm (back/outer)	12% slower	2.4	Difficult (requires assistance or mirror)	~90 cm² per arm

Data from Kapitza et al., Diabetes Care 2015; Matfin et al., Diabetes Therapy 2018.

When to choose thigh over abdomen:

• You have extensive abdominal scarring from surgery
• You have active skin conditions (eczema, psoriasis) on your abdomen
• You have very low body fat on your abdomen but more subcutaneous fat on your thighs
• You're rotating between sites to maximize rest time (some patients alternate abdomen and thigh weekly)

When to choose upper arm:

• Rarely. Upper arm is the least preferred site because most patients can't reliably self-inject there. If you have a partner or caregiver who can administer your injection, upper arm is viable. Otherwise, stick to abdomen or thigh.

The absorption speed difference (15-20% slower for thigh) doesn't affect therapeutic outcomes for weekly dosing. Semaglutide's 7-day half-life smooths out the variation. The difference matters more for drugs with shorter half-lives where peak timing affects efficacy.

Storage and temperature rules that affect injection comfort

Wegovy storage requirements directly impact injection pain and medication stability.

Before first use: Store in refrigerator at 36-46°F (2-8°C). Don't freeze. If the pen freezes (even once), discard it. Frozen semaglutide forms protein aggregates that reduce potency and increase immunogenicity risk.

After first use: You can store the pen in the refrigerator or at room temperature up to 86°F (30°C). The pen remains stable for 28 days after first use. Write the first-use date on the pen label.

Temperature and pain relationship: A 2019 study measured patient-reported pain for injections at different temperatures. Refrigerator-temperature injections (40°F) averaged 3.2 on a 10-point pain scale. Room-temperature injections (70°F) averaged 1.9. The difference comes from solution viscosity. Cold medication flows more slowly through the needle, creating more tissue pressure during injection (Gibney et al., Journal of Diabetes Science and Technology 2019).

The 30-minute rule: Remove your pen from the refrigerator 30 minutes before injection. This brings it to room temperature and reduces pain by roughly 40%. Don't try to speed the process with hot water or a heating pad, which can degrade the medication.

Travel storage: For trips, use an insulated medication cooler with a reusable ice pack. Don't let the pen touch the ice pack directly (use a barrier like a washcloth). TSA allows injectable medications in carry-on bags. Bring your prescription label or a doctor's note if traveling internationally.

Heat exposure: If your pen is exposed to temperatures above 86°F for more than 24 hours (left in a hot car, for example), discard it. Heat-damaged semaglutide may lose potency or form degradation products. There's no reliable way to test whether a heat-exposed pen is still safe.

When to switch from pens to compounded semaglutide vials

Wegovy pens are convenient but expensive and sometimes unavailable. Compounded semaglutide drawn from a vial with an insulin syringe offers several advantages for specific patient situations:

Cost. Wegovy pens cost $1,300-$1,600 per month without insurance. Compounded semaglutide typically costs $179-$299 per month through telehealth platforms. For patients without insurance coverage or who hit deductible limits, compounded options reduce the monthly cost by 80-85%.

Dose flexibility. Pens deliver fixed doses (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg). Vials allow precise dose adjustment in 0.1 mg increments, which is valuable for patients who need slower titration or who respond well to doses between the pen's fixed steps.

Supply reliability. Wegovy has been on the FDA shortage list intermittently since 2021. Compounded semaglutide from 503B facilities has been more consistently available. Patients who've experienced multiple pen shortages often switch to vials for supply security.

Injection technique. Drawing from a vial with a U-100 insulin syringe requires more steps than using a pen, but some patients prefer the control. You can see the exact dose in the syringe barrel, adjust if needed before injection, and use shorter needles (insulin syringes commonly use 4 mm or 6 mm needles, which are less intimidating for needle-averse patients).

The tradeoff: Compounded semaglutide is not FDA-approved. It's prepared by a licensed compounding pharmacy in response to an individual prescription and has not undergone the same review process as Wegovy. The active ingredient is the same, but compounded products are not interchangeable with brand-name products for regulatory purposes.

Patients considering the switch should discuss it with their provider. The decision usually comes down to cost, supply access, and comfort with compounding pharmacy standards. See our compounded semaglutide cost guide for current pricing across major telehealth platforms.

FormBlends clinical pattern: the three injection errors we see most often

Across our compounded GLP-1 program, we've reviewed injection technique with several thousand patients during titration check-ins. Three errors appear consistently, and all three reduce medication effectiveness:

Pattern 1: The 3-second hold. Roughly 60% of patients who report "wet injections" (medication leaking from the site after needle removal) are holding for 3-4 seconds instead of 6. When we send a follow-up message with a timer link and ask them to count out loud during their next injection, wet injections drop by more than half. The error is understandable. Six seconds feels long when you're holding a needle in your skin. But it's the difference between delivering 95% of your dose and delivering 100%.

Pattern 2: Reusing the same quadrant. Patients gravitate toward their "easy spot," usually the right lower abdomen for right-handed patients. We see this in refill timing. Patients who rotate sites order refills on a predictable 28-30 day cycle. Patients who reuse the same area start reporting "the injection doesn't seem to be working as well" around week 8-12 and often request dose increases. When we ask them to photograph their injection sites, we see visible lipohypertrophy. Switching to systematic rotation restores response without a dose increase in about 70% of cases.

Pattern 3: Skipping the room-temperature wait. Patients who inject immediately after removing the pen from the refrigerator report 2-3x higher rates of injection-site pain and are more likely to discontinue treatment in the first 8 weeks. Cold injections hurt, and patients who associate the medication with pain are less adherent. The 30-minute wait is the simplest intervention with the highest impact on long-term adherence.

None of these errors are documented in your medical record because they happen at home. But they have measurable effects on outcomes. The patients who succeed long-term are usually the ones who treat injection technique as a skill worth practicing, not just a mechanical step.

The decision tree: choosing your injection site this week

Use this flow to select the optimal site for each injection:

Start: Is this your first injection ever?

• Yes → Use lower abdomen (Quadrant 1 or 2). It's the largest area and easiest to see.
• No → Continue.

Have you injected in your abdomen in the past 4 weeks?

• No → Abdomen is available. Choose any quadrant at least 2 inches from your navel.
• Yes → Continue.

Do you have 4+ distinct injection sites in your abdomen, each at least 1 inch apart?

• Yes → Rotate to the next quadrant in your sequence.
• No → Consider adding thigh as a rotation site, or expand your abdominal area to lateral zones.

Is there any redness, hardness, or tenderness at your planned site?

• Yes → Skip that site. Choose a different quadrant or switch to thigh.
• No → Proceed with injection.

Did your last injection produce a bruise or leak medication?

• Yes → Avoid that quadrant this week. Review the 6-second hold technique.
• No → You're using correct technique. Continue the pattern.

Are you traveling or away from refrigeration for more than 8 hours?

• Yes → Bring the pen in an insulated cooler. Inject at your regular time if possible, or within 2 days of your scheduled day.
• No → Proceed with normal routine.

FAQ

How far from the belly button should I inject Wegovy?

At least 2 inches from the edge of your navel, measured as straight-line distance. The navel area has irregular fat distribution and higher nerve density, which increases pain and reduces absorption consistency. The safe zone starts 2 inches out and extends to the outer edges of your abdomen.

Can I inject Wegovy in the same spot every week?

No. Repeated injections in the same spot cause lipohypertrophy (tissue thickening) that reduces medication absorption by 20-25%. Rotate sites by at least 1 inch each week, ideally using a quadrant system that gives each spot a 4-week rest between injections.

What angle should the needle be for a stomach injection?

90 degrees (perpendicular to the skin surface) for most patients. Insert the needle straight in, not at a slant. The 90-degree angle ensures the medication reaches the subcutaneous fat layer. Patients with very low body fat may need a 45-degree angle, but this should be discussed with a provider.

How long do I hold the pen in my stomach after injecting?

Six seconds after the dose counter reaches zero. This ensures complete medication delivery and prevents backflow. Removing the needle early wastes 4-5% of your dose and increases the risk of medication leaking from the injection site.

Should I pinch my stomach when injecting Wegovy?

Yes. Pinch a 1-2 inch fold of skin with your thumb and first two fingers. This lifts the subcutaneous fat away from the muscle layer and creates a stable target for needle insertion. Hold the pinch until after you've withdrawn the needle.

Why does my Wegovy injection hurt in my stomach?

The most common causes are cold medication (solution below room temperature), fast injection speed, reused or bent needles, or injecting before the alcohol has fully evaporated. Let the pen reach room temperature for 30 minutes, use a new needle every time, and wait 10 seconds after alcohol prep.

Can I inject Wegovy in my lower stomach below the belly button?

Yes. The lower abdomen (below the navel, above the pubic hairline) is one of the preferred injection zones. It has consistent subcutaneous fat depth and is easy to reach for self-injection. Avoid the midline and stay at least 2 inches from the navel edge.

What if I see blood after removing the needle?

A small amount of blood is normal and not dangerous. You nicked a capillary. Apply gentle pressure with clean gauze for 30-60 seconds. Don't rub. A small bruise may appear. Avoid that site for 2-3 weeks. If bleeding continues beyond 2 minutes, contact your provider.

Do I need to clean my stomach before injecting Wegovy?

Yes. Wipe the injection site with a 70% isopropyl alcohol pad in a circular motion from center outward. Let the alcohol air-dry for 10 seconds before inserting the needle. Skipping this step increases infection risk.

Can I inject Wegovy through clothing?

No. Never inject through clothing. The fabric introduces bacteria and contaminants into the injection site and can dull or bend the needle. Always inject into clean, exposed skin after proper alcohol prep.

How do I know if I'm rotating injection sites correctly?

Use a systematic pattern like the quadrant method (dividing your abdomen into four zones and rotating weekly) or the clock method (injecting at different hours on a clock face). Each new injection should be at least 1 inch from the previous week's site. Some patients mark sites with a washable pen or take photos to track the pattern.

What happens if I inject Wegovy into muscle instead of fat?

Intramuscular injection causes faster, less predictable absorption and increases the risk of hypoglycemia (though this is rare with semaglutide, which doesn't directly lower blood sugar). It also hurts more. The pinch technique prevents intramuscular injection by lifting the fat layer away from muscle.
