What did @caterina.beauty actually say?
The creator walked through the steps of priming and injecting with an Ozempic pen. She described removing two needle caps, priming the pen by turning the dose selector to "the first line" and pressing the plunger until medication appears, dialing the dose, inserting the needle fully, and holding the plunger for six seconds before removing. That is the basic shape of correct technique. But some of the language is muddled enough to cause real confusion.
She refers to the dose window as "door styles" throughout, which is clearly a speech or transcription artifact for "dose dial" or "dose window." She also says the needle "is only planned the first time you use the pin," which appears to mean priming is a once-off step. That is wrong, and it matters.
Does the science back this up?
The core injection sequence she describes is broadly consistent with Novo Nordisk's own prescribing information and patient guides for semaglutide (Ozempic). The six-second hold after pressing the plunger is real guidance, not invented. A 2022 review by Flood et al. in Diabetes Therapy found that inadequate needle dwell time is one of the most common causes of incomplete dose delivery with auto-injector and dial-a-dose pens.
The instruction to push the needle "all the way into the skin" is consistent with standard subcutaneous injection technique for most adults. Research published by Hirsch et al. (2014, Diabetes Technology and Therapeutics) confirmed that for most patients using 4mm or 5mm pen needles, a 90-degree insertion without skin lifting is appropriate and avoids intramuscular injection. Nothing in her technique advice contradicts this.
What did they get wrong (or right)?
The biggest error is the claim that priming is done only once, on the first use of the pen. Novo Nordisk's official Ozempic instructions are explicit: you prime the pen before every new needle is attached, not just at the start of a new pen. Every time you swap needles, air and small amounts of medication can enter the needle hub, and priming clears that. Skipping it risks delivering less medication than intended.
She gets the discard step right: the inner needle cap is thrown away, the outer cap is kept to remove the needle afterward. That is correct and actually important, since recapping with the outer cap before disposal reduces needlestick risk.
The six-second count before withdrawal deserves credit. It is not dramatic filler. Insulin and GLP-1 pen studies consistently show that patients who withdraw immediately after pressing the plunger lose a measurable amount of dose from the injection site. The six-second window allows pressure to dissipate and medication to disperse.
One genuine gap: she does not mention injection site rotation. Semaglutide should be rotated across the abdomen, thigh, and upper arm to prevent lipohypertrophy, a condition where repeated injections in the same spot cause fatty tissue buildup that impairs absorption (Blanco et al., 2013, Diabetes Care).
What should you actually know?
If you are using an Ozempic pen, prime it before every injection, not just the first time you open a new pen. Attach a fresh needle, point it up, dial to the flow check symbol, press until you see a drop or small stream of medication, then dial your prescribed dose. Do not use the dose your TikTok creator used. Your dose is between you and your prescribing clinician.
Australia's Therapeutic Goods Administration classifies semaglutide as a Schedule 4 prescription-only medication. Using it without a valid prescription is not legal, and sourcing it from unregulated suppliers carries serious risks including counterfeit product and incorrect concentration. Ozempic (0.5mg, 1mg, 2mg per dose) and Wegovy (2.4mg) are different products with different approved indications. They are not interchangeable without clinical oversight.
- Prime before every injection, not just the first
- Rotate injection sites each week to reduce tissue damage
- Hold the plunger for at least six seconds before withdrawing
- Store unused pens in the fridge; in-use pens can be kept at room temperature for up to 56 days
- Always use a new needle for each injection to reduce infection risk and ensure accurate dosing
