Saxenda injection technique: What TikTok gets right and wrong

What did @kellyramirez30 actually say?

Kelly walked her 18K viewers through her personal Saxenda (liraglutide) self-injection routine, covering hand washing, alcohol swabbing, needle attachment, site selection, and sharps disposal. She recommended the stomach, arm, or thigh as injection sites, showed a hair clip trick to pinch arm skin solo, counted to eight seconds after injecting, and told viewers not to throw needles in the trash. She added a disclaimer that she is not a doctor, which matters here.

The video reads as practical and well-intentioned. Most of what she demonstrated tracks with standard subcutaneous injection technique. A few specifics, however, deserve closer scrutiny, particularly around alcohol prep, gloves, and whether her disposal advice covers all situations adequately.

Does the science back this up?

Mostly yes, with some caveats. The core injection mechanics she demonstrated, pulling the cap, attaching the needle, pinching the skin, injecting slowly, and counting seconds before withdrawing, are consistent with Novo Nordisk's prescribing information for Saxenda and standard subcutaneous injection guidance from nursing literature.

The eight-second hold she counted out is actually supported. A 2015 study by Berard et al. in Diabetes Technology and Therapeutics found that longer needle dwell time (at least six seconds) reduced insulin leakage at the injection site for subcutaneous injections. While that research focused on insulin, the pharmacokinetic logic applies to other subcutaneous peptides like liraglutide. The three recommended sites, abdomen, thigh, and upper arm, are exactly what Saxenda's label specifies. Site rotation to avoid lipohypertrophy is not mentioned in the video, which is a genuine gap.

What did they get wrong (or right)?

The alcohol prep method is where things get sloppy. Kelly poured alcohol directly onto a paper towel and rubbed it over the pen tip, saying you want to rub "necessarily on top because that's where the medication is gonna be coming out of." That is backwards. You swab the injection site on your skin, not the pen needle tip. Rubbing alcohol on the needle itself before injection is not part of standard technique and could theoretically introduce lint or fiber contamination. The Saxenda instructions for use do not include this step.

On gloves: she called them "a little bit extra." For home self-injection in a non-clinical setting, she is not wrong. The CDC's guidance on home injection technique does not require gloves for self-administered subcutaneous medications. Credit where it is due.

Her sharps disposal advice is directionally correct. The FDA recommends FDA-cleared sharps disposal containers, and she correctly noted that pharmacies often accept them. The suggestion to use a "block baggie" as an interim solution is not FDA-endorsed but reflects real-world guidance from some harm reduction and waste programs. It is worth stating plainly: a sealed, puncture-resistant container is the correct standard.

What should you actually know?

If you are self-injecting a GLP-1 medication like Saxenda, the things that actually matter clinically are site rotation, proper subcutaneous depth, needle length appropriateness for your body composition, and consistent timing relative to meals and your weekly or daily schedule. Liraglutide is a daily injection, and consistency affects tolerability.

A 2021 review by Frid et al. in Diabetes Care examined injection technique errors across thousands of patients and found that lipohypertrophy (hardened fatty tissue from repeated injections in the same spot) affected up to 41% of insulin users who did not rotate sites. The same risk applies to any subcutaneous peptide. Kelly does not mention rotation at all, and for a 18K-view tutorial, that omission has real consequences.

Dose escalation for Saxenda follows a specific titration schedule set by your prescriber. The 0.6 mg dose Kelly mentions is the starting dose, not a maintenance dose. Viewers watching this should not interpret her dose as a target or recommendation for their own use.

The bottom line on this video

Kelly's tutorial is more accurate than harmful, which puts it ahead of a lot of GLP-1 content on TikTok. She got the mechanics right, she included a disclaimer, and her disposal messaging is mostly sound. The alcohol swab error is a genuine technique mistake that 18,000 people may now replicate incorrectly. The absence of any mention of site rotation is a real gap in an otherwise practical video. The hair clip arm-pinch hack is creative and not clinically problematic. If you are starting a GLP-1 injection for the first time, this video is a reasonable visual reference, but read your medication's actual instructions for use and confirm technique with your prescriber or pharmacist.
