Daily GLP-1 agonist (Saxenda / Victoza). Daily-injection-class tradeoffs vs weekly compounds.
- Half-life
- 13 h
- Out of system
- ~2.7 days
- Route
- Subcutaneous
- Level
- Intermediate
Daily dosing holds steady levels. After the last dose, roughly 97% has cleared in ~2.7 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Liraglutide is used for
- Older daily-injection GLP-1, well-documented safety profile
- Modest weight loss (~6–8%) and glucose control
- Useful when weekly GLP-1s aren't tolerated
How it's typically used
Prescription titration: 0.6 mg subq daily → 1.2 → up to 3 mg (Saxenda).
What to watch for
- Daily injection is a chore vs weekly options
- Same GI + pancreatitis class warnings
- Avoid with thyroid carcinoma history

About GLP-1 & weight loss
- What they are
- Incretin analogues — GLP-1 and dual/triple agonists. They slow stomach emptying and act on appetite centres in the brain, so you eat less without white-knuckling it.
- How they're run
- One subcutaneous shot a week for most, on the same day each week. Doses climb in steps every four weeks; that slow titration is what keeps side effects tolerable.
- What to watch
- Nausea, constipation, and reflux are near-universal in the first month. Muscle is lost alongside fat unless you keep protein high and keep lifting. Tell any surgeon or anaesthetist you are on one.
