LiraglutideBenefits, Dosage & Interactions
Also known as: saxenda, victoza
Liraglutide is a medication classified as a glucagon-like peptide-1 (GLP-1) receptor agonist. It is administered via subcutaneous injection. Liraglutide's primary actions involve mimicking the effects of natural GLP-1, a hormone produced in the gut that plays a role in blood sugar regulation and appetite.

How to track Liraglutide doses
Liraglutide is tracked as a protocol rather than a single reminder: a vial with a concentration, a schedule that may be titrated or cycled, and a rotation of injection sites. Here is the record that keeps all three consistent.
- 1
Record the vial and concentration
Log the vial strength and the volume of bacteriostatic water you added so Liraglutide is stored as a concentration rather than a guess. DoseRoutine converts that into mg per syringe unit and counts the doses left in the vial as you log.
- 2
Set the schedule, not just a reminder
Enter the dose in mg and the frequency. Cycled protocols get a start and end date so the history stays accurate when Liraglutide comes out of the routine.
- 3
Rotate and log the injection site
Pick the site at the moment you log the dose. The site map shows what you used last and how recently, which is the part that drifts fastest when two compounds run on different frequencies.
- 4
Log adherence, not intentions
Mark each dose taken, skipped or delayed as it happens. Weeks of honest logs are what make an adherence rate or a trend line meaningful; retrospective guessing is not.
- 5
Review against outcomes
With a reported half-life around 13 h, effects and timing shifts show up over days rather than instantly. Review Liraglutide alongside your logged metrics and any relevant blood work every few weeks before changing the dose.
What to log each time
- Dose in mg and the syringe units it worked out to
- Vial: reconstitution date, concentration, doses remaining
- Injection site and time
- Any side effects in the 24 h after the dose

What interacts with Liraglutide?
| Interacts with | Severity | Type | What happens | What to do |
|---|---|---|---|---|
| Any glp1 + supplement | Note | Category ruleConfidence: theoretical | GLP-1 medications slow stomach emptying, changing how/when oral supplements absorb; rapid weight loss raises the importance of protein and micronutrients.Source pending | Time oral supplements when nausea is lowest; prioritize protein and micronutrients; discuss with your provider. |
| Insulin (Rapid) | Caution | Compound pairConfidence: theoretical | Combining a GLP-1 with rapid insulin increases hypoglycemia risk.Source pending | Reduce mealtime insulin at GLP-1 initiation; monitor glucose closely. |
| Insulin (Long-Acting) | Caution | Compound pairConfidence: theoretical | GLP-1 plus basal insulin increases hypoglycemia risk.Source pending | Reduce basal insulin dose 10–20% at GLP-1 initiation and titrate. |
