Key Takeaways

• The lowest dose of Wegovy is 0.25 mg administered subcutaneously once weekly for the first four weeks of treatment
• This starter dose is not therapeutic for weight loss but exists to reduce gastrointestinal side effects during the body's adaptation period
• Skipping the 0.25 mg dose and starting higher increases discontinuation rates by 34% according to post-market surveillance data
• The full five-month titration schedule (0.25, 0.5, 1.0, 1.7, 2.4 mg) is designed around semaglutide's 7-day half-life and GLP-1 receptor upregulation kinetics

Direct answer (40-60 words)

The lowest dose of Wegovy (semaglutide) is 0.25 mg injected once weekly. This starter dose is used for the first month of treatment to allow gradual adaptation to GLP-1 receptor activation. It's a tolerability dose, not a therapeutic one. Weight loss typically begins at 0.5 mg or higher after the first titration step.

The complete Wegovy titration schedule

Wegovy's FDA-approved titration protocol spans five months before reaching the maintenance dose:

Month	Weekly Dose	Pen Color	Purpose
Month 1	0.25 mg	White with gray label	Tolerability initiation
Month 2	0.5 mg	White with blue label	Early therapeutic effect
Month 3	1.0 mg	White with pink label	Moderate therapeutic dose
Month 4	1.7 mg	White with yellow label	High therapeutic dose
Month 5+	2.4 mg	White with green label	Maintenance dose

Each pen contains four single-use doses. You inject once weekly on the same day each week (the specific day doesn't matter, but consistency does). The pen design prevents dose adjustment, so you can't "split" a 0.5 mg pen into two 0.25 mg doses.

The schedule is not negotiable in the brand-name product. Novo Nordisk doesn't manufacture a 0.125 mg pen or a 3.0 mg pen. The doses you see in the table are the only doses available. Compounded semaglutide allows more granular titration, which we'll address below.

Why 0.25 mg exists when it doesn't cause weight loss

The 0.25 mg dose produces minimal weight loss. In the STEP 1 trial (Wilding et al., New England Journal of Medicine, 2021), participants on 0.25 mg for four weeks lost an average of 0.9% of body weight, compared to 0.4% in the placebo group during the same period. The difference is statistically significant but clinically irrelevant.

The dose exists for one reason: GLP-1 receptor density in the gastrointestinal tract.

When semaglutide binds to GLP-1 receptors in the stomach and intestines, it slows gastric emptying. The slower the emptying, the longer food sits in the stomach, and the stronger the nausea signal. At therapeutic doses (1.7 mg or 2.4 mg), this effect is pronounced. Starting at those doses without titration produces intolerable nausea in 40 to 60% of patients (Rubino et al., Lancet, 2021).

The 0.25 mg dose triggers mild GLP-1 receptor activation without overwhelming the system. Over four weeks, the body compensates through receptor desensitization and upregulation of competing pathways. By week five, the same person who would have experienced severe nausea at 0.5 mg on day one can tolerate it with minimal symptoms.

This adaptation period is not optional. The STEP trials required the titration schedule as part of the protocol. Patients who skipped steps weren't studied, so we don't have controlled trial data on what happens if you jump from 0.25 mg to 1.7 mg. We do have post-market data, and it's not encouraging.

What most articles get wrong about "skipping" the starter dose

A common claim in online weight-loss communities: "The 0.25 mg dose is a waste of time. Just start at 0.5 mg or 1.0 mg and save money."

The error here is conflating "no weight loss" with "no physiological effect." The 0.25 mg dose has profound effects on gastric emptying, bile acid secretion, and pancreatic enzyme release. Those effects are dose-dependent but not linear. Doubling the dose doesn't double the nausea; it can quintuple it.

A 2023 analysis of FDA Adverse Event Reporting System (FAERS) data (Sodhi et al., Diabetes Care, 2023) found that patients who self-escalated doses faster than the labeled schedule had a 34% higher rate of treatment discontinuation in the first 90 days compared to those who followed the protocol. The most common reason for discontinuation was persistent nausea and vomiting requiring medical intervention.

The second error is assuming the schedule is about weight loss. It's not. It's about retention. Novo Nordisk's internal pharmacoeconomic models (disclosed in their 2022 investor presentation) show that every additional month a patient stays on Wegovy increases lifetime revenue by approximately $1,400. The titration schedule is designed to maximize adherence, not to maximize month-one weight loss.

Skipping the 0.25 mg dose might get you to therapeutic doses faster, but if you discontinue at week six because you can't tolerate the side effects, you've lost more time than you saved.

The pharmacokinetic reason the schedule can't be compressed

Semaglutide has a half-life of approximately seven days (Lau et al., Clinical Pharmacokinetics, 2015). That means it takes five half-lives, or 35 days, to reach steady-state concentration after starting a new dose.

Here's what happens when you inject 0.25 mg weekly:

• Week 1: Peak concentration around 24 to 48 hours post-injection, then gradual decline.
• Week 2: Second dose adds to the residual from week one. Trough concentration is now higher.
• Week 3: Third dose. Trough is higher still.
• Week 4: Fourth dose. You're approaching steady state.
• Week 5: Switch to 0.5 mg. The process starts over.

If you compressed the schedule and increased every two weeks instead of every four, you'd never reach steady state at any dose. You'd be chasing a moving target, and the side effect profile would be unpredictable.

The four-week intervals align with the drug's half-life. By week four, your body has adapted to the steady-state concentration of 0.25 mg. When you step up to 0.5 mg, the increment is smaller relative to what your receptors are already seeing, so the side effect spike is manageable.

The STEP 5 trial (Garvey et al., Nature Medicine, 2022) tested a two-year extension of Wegovy. Patients who stayed on 2.4 mg for 104 weeks had stable trough concentrations after month five and no further increase in nausea rates. The titration schedule front-loads the adaptation period so the maintenance phase is smooth.

Wegovy dosing vs. compounded semaglutide starting doses

Compounded semaglutide doesn't come in pre-filled pens. It's dispensed in multi-dose vials, and you draw the dose yourself with an insulin syringe. This allows more granular titration.

Common compounded semaglutide starting doses:

Dose	Units (at 2.5 mg/mL)	Units (at 5 mg/mL)	Comparison to Wegovy
0.125 mg	5 units	2.5 units	Half the Wegovy starter dose
0.25 mg	10 units	5 units	Equivalent to Wegovy month 1
0.375 mg	15 units	7.5 units	Between Wegovy month 1 and 2
0.5 mg	20 units	10 units	Equivalent to Wegovy month 2

Some compounding protocols start at 0.125 mg for patients with a history of severe nausea, gastroparesis, or prior GLP-1 intolerance. This ultra-low dose isn't available in the brand-name product.

The trade-off is precision. Wegovy pens deliver exactly 0.25 mg every time. Compounded semaglutide requires you to draw the dose accurately with a syringe, and small errors (drawing 12 units instead of 10) can add up. For detailed instructions on drawing compounded doses, see our semaglutide reconstitution guide.

FormBlends clinical pattern: Across our patient population, we see two distinct titration approaches. Patients with no prior GLP-1 exposure typically start at 0.25 mg and follow a Wegovy-equivalent schedule. Patients transitioning from liraglutide (Saxenda) or switching from tirzepatide often tolerate starting at 0.5 mg because their GLP-1 receptors are already adapted. The decision is individualized, but the default remains 0.25 mg unless there's a clinical reason to deviate.

What happens if you stay at 0.25 mg longer than four weeks

The FDA label specifies four weeks at 0.25 mg, but the label is a guideline, not a law. Your provider can extend the starter dose if you're experiencing intolerable side effects or if there's a medical reason to delay titration.

Reasons to stay at 0.25 mg longer than four weeks:

• Persistent nausea or vomiting that hasn't resolved by week three.
• Concurrent illness (flu, COVID-19, gastroenteritis) that makes it hard to distinguish drug side effects from illness symptoms.
• Upcoming travel or major life event where you don't want to risk side effects from a dose increase.
• Patient preference if you're seeing early appetite suppression and want to consolidate the effect before increasing.

The downside is time. Every extra week at 0.25 mg delays reaching the therapeutic dose by a week. If your goal is maximum weight loss in the shortest time, extending the starter dose works against you. If your goal is minimizing side effects and staying on the medication long-term, it's a reasonable trade.

There's no published data on outcomes for patients who stay at 0.25 mg for eight weeks instead of four. The STEP trials didn't test that protocol. Anecdotally, patients who extend the starter dose have lower discontinuation rates but slower initial weight loss. The weight loss eventually catches up once they reach maintenance doses.

The decision tree: when to delay, hold, or reduce your dose

Use this framework to decide whether to proceed with the next scheduled dose increase:

If you have zero or mild side effects (no nausea, or nausea that resolves within 48 hours of injection):

• Proceed with the scheduled increase.

If you have moderate side effects (nausea lasting 3 to 5 days, one episode of vomiting, or persistent but tolerable abdominal discomfort):

• Stay at the current dose for one additional week, then reassess.
• If symptoms improve, proceed with the increase.
• If symptoms persist, stay at the current dose for a second additional week, then contact your provider.

If you have severe side effects (vomiting more than twice in 24 hours, inability to keep down liquids, severe abdominal pain, or signs of dehydration):

• Hold the next dose.
• Contact your provider within 24 hours.
• Do not increase the dose until symptoms fully resolve and your provider clears you.

If you've had zero side effects and zero appetite suppression after four weeks at the current dose:

• Proceed with the scheduled increase. Lack of side effects doesn't mean the drug isn't working; some patients don't experience nausea but still lose weight.

If you've had a major adverse event (pancreatitis, gallbladder disease, severe allergic reaction):

• Stop the medication immediately.
• Contact your provider and do not restart without explicit clearance.

This is the FormBlends Five-Point Dose Escalation Decision Model. It's designed to balance efficacy with tolerability and to give you clear action steps at each branch point.

Side effect patterns at each titration step

The STEP 1 trial tracked adverse events at each dose level. Here's what the data shows:

Dose	Nausea (% of patients)	Vomiting (% of patients)	Diarrhea (% of patients)	Constipation (% of patients)
0.25 mg	12%	3%	8%	6%
0.5 mg	22%	7%	14%	11%
1.0 mg	28%	10%	18%	15%
1.7 mg	33%	12%	21%	18%
2.4 mg	44%	16%	30%	24%

(Wilding et al., NEJM, 2021)

A few patterns worth noting:

• Nausea peaks in the first week after each dose increase, then declines. By week three at a new dose, nausea rates drop to near-baseline.
• Vomiting is less common than nausea but follows the same pattern. Most vomiting episodes are single events, not persistent.
• Diarrhea and constipation can alternate. Some patients experience diarrhea in week one of a new dose, then constipation in weeks two and three as gastric emptying slows further.
• The 2.4 mg dose has the highest side effect rates, but also the highest efficacy. The average weight loss at 68 weeks was 14.9% of body weight at 2.4 mg vs. 2.4% with placebo.

The side effect profile is why the lowest dose matters. Starting at 0.25 mg gives you a 12% nausea rate instead of a 44% nausea rate. That difference determines whether you stay on the medication.

Storage and administration specifics for the 0.25 mg pen

Wegovy pens are stored in the refrigerator (36 to 46°F) until first use. Once you've used a pen, you can keep it at room temperature (up to 86°F) for 28 days or continue refrigerating it. Don't freeze.

The 0.25 mg pen contains four doses. Each dose is a single use. After you inject, you'll see a yellow bar in the dose counter window, indicating the pen is empty for that dose. You can't reuse a pen after the dose counter shows yellow.

Injection technique for the 0.25 mg pen:

1. Remove the pen from the refrigerator 15 minutes before injection to let it warm to room temperature. Cold injections sting more.
2. Attach a new pen needle (31-gauge, 5/16-inch is standard). Screw it on clockwise until tight.
3. Prime the pen by dialing to the flow-check symbol, then pressing the dose button until you see a drop of liquid at the needle tip. This removes air.
4. Dial the dose selector to 0.25 mg (it clicks into place).
5. Choose an injection site: abdomen (avoid 2 inches around the navel), front or outer thigh, or back of the upper arm. Rotate sites weekly.
6. Pinch a fold of skin. Insert the needle at 90 degrees. Press the dose button all the way down and hold for six seconds (count "one-thousand-one, one-thousand-two..." to six). This ensures the full dose is delivered.
7. Withdraw the needle. Dispose of it in a sharps container. Recap the pen and store it.

The six-second hold is critical. Semaglutide is viscous, and releasing the button too early can leave residual medication in the pen, underdosing you.

When the lowest dose is actually the right maintenance dose

The 2.4 mg maintenance dose is not universal. Some patients reach their goal weight at lower doses and stay there.

A 2024 post-hoc analysis of the STEP trials (Rubino et al., Obesity, 2024) found that 11% of participants who reached at least 10% body weight loss did so at doses below 2.4 mg and chose to remain at those doses rather than continue titrating. The most common maintenance dose in this subgroup was 1.0 mg.

When staying at a lower dose makes sense:

• You've reached your goal weight and maintaining it at the current dose.
• You're experiencing intolerable side effects at higher doses that resolve when you step back down.
• You're older (65+) and at higher risk for muscle loss; lower doses may preserve lean mass better (though data is limited).
• You're using semaglutide off-label for appetite control or metabolic health rather than weight loss, and the current dose achieves your goal.

The countervailing view: staying at a subtherapeutic dose leaves efficacy on the table. The STEP 1 data shows a clear dose-response relationship. At 1.0 mg, average weight loss was 10.2% at 68 weeks. At 2.4 mg, it was 14.9%. If your goal is maximum weight loss, stopping at 1.0 mg means you're leaving 4.7 percentage points of body weight on the table.

The decision is individual. If you're at 1.0 mg, tolerating it well, and happy with your results, there's no medical requirement to increase. If you're at 1.0 mg and frustrated that weight loss has plateaued, increasing to 1.7 mg or 2.4 mg is the next step.

Steelmanning the case against the five-month titration schedule

A thoughtful clinician might argue the titration schedule is too conservative and that a faster protocol would produce better real-world outcomes.

The argument: the five-month ramp delays therapeutic effect. Patients lose motivation when they don't see results in month one. Faster titration (two weeks per step instead of four) would get patients to 2.4 mg in 10 weeks instead of 20, doubling the time spent at therapeutic doses over a one-year treatment window.

The supporting evidence: tirzepatide (Mounjaro, Zepbound) uses a faster titration schedule (four weeks at 2.5 mg, then increase every four weeks), and discontinuation rates in the SURMOUNT trials were comparable to the STEP trials despite the faster ramp. This suggests patients can tolerate faster titration if the drug's side effect profile allows it.

The counterargument: semaglutide and tirzepatide have different receptor binding profiles. Tirzepatide is a dual GIP/GLP-1 agonist, and the GIP component may offset some of the GLP-1-mediated nausea. Semaglutide is GLP-1 only, so the nausea signal is stronger at equivalent doses. The STEP trials tested the five-month schedule specifically for semaglutide, and it's the only protocol with long-term safety and efficacy data.

The real-world data leans toward the conservative schedule. The 34% higher discontinuation rate in patients who self-escalate faster (Sodhi et al., 2023) suggests the five-month ramp is calibrated correctly for semaglutide's pharmacology.

That said, individual variation is real. Some patients tolerate faster titration. Compounded semaglutide allows testing that hypothesis under provider supervision. Brand-name Wegovy does not.

FAQ

What is the lowest dose of Wegovy available? The lowest dose of Wegovy is 0.25 mg, administered once weekly via subcutaneous injection. This is the starting dose for the first four weeks of treatment.

Can I start Wegovy at a higher dose than 0.25 mg? The FDA-approved protocol starts at 0.25 mg. Starting higher is off-label and increases the risk of severe nausea and vomiting. Most providers follow the labeled titration schedule unless there's a specific clinical reason to deviate.

How long do I stay on the 0.25 mg dose? Four weeks. You inject 0.25 mg once weekly for four doses, then increase to 0.5 mg in week five. Your provider may extend the 0.25 mg phase if you're experiencing intolerable side effects.

Will I lose weight on the 0.25 mg dose? Minimal weight loss occurs at 0.25 mg. The average in clinical trials was 0.9% of body weight over four weeks. The dose exists for tolerability, not efficacy.

What if I can't tolerate the 0.25 mg dose? Severe intolerance to 0.25 mg is rare but possible. Contact your provider. Options include extending the time between doses (injecting every 10 days instead of every 7), switching to a different GLP-1 medication, or discontinuing.

Can I skip the 0.25 mg dose and start at 0.5 mg? Not with brand-name Wegovy, which comes in single-dose pens. With compounded semaglutide, your provider could prescribe 0.5 mg as a starting dose, but this increases side effect risk and isn't recommended without prior GLP-1 exposure.

Is 0.25 mg of Wegovy the same as 0.25 mg of Ozempic? Yes. Wegovy and Ozempic both contain semaglutide. The 0.25 mg dose is chemically identical. The difference is indication (Wegovy for weight loss, Ozempic for type 2 diabetes) and available doses.

How much does the 0.25 mg Wegovy pen cost? List price is approximately $1,430 per month (four pens) as of 2026. Insurance coverage varies. Compounded semaglutide at 0.25 mg costs $200 to $350 per month depending on the pharmacy.

Can I stay on 0.25 mg long-term instead of increasing? You can, but you won't see therapeutic weight loss. The 0.25 mg dose is subtherapeutic. If your goal is weight loss, you need to titrate to at least 1.0 mg.

What's the difference between the 0.25 mg dose and the 0.5 mg dose? The 0.5 mg dose is double the concentration. It produces more appetite suppression, more weight loss, and a higher rate of gastrointestinal side effects. The 0.5 mg dose is the first step where most patients notice meaningful appetite reduction.

Do I need to refrigerate the 0.25 mg pen after I start using it? You can refrigerate it or keep it at room temperature (up to 86°F) for up to 28 days after first use. Don't freeze. Most patients continue refrigerating to maximize shelf life.

Can I split a 0.5 mg pen into two 0.25 mg doses? No. Wegovy pens are single-dose devices. Once you press the dose button, the full dose is delivered. You can't partially inject or save half a dose.
