Injection day & dosing
Injection technique, timing, missed doses and dose escalation questions for people on a GLP-1.
-
Where to inject a GLP-1: stomach, thigh or arm?
Stomach, front of the thigh or upper arm all work: the labels show similar drug levels from each. Rotate the spot every week and skip sore or scarred skin.
-
Missed a GLP-1 dose: what to do
Ozempic: take it within 5 days, else skip. Wegovy: take it if the next shot is 2+ days away. Zepbound, Mounjaro: 4 days. Daily pills: skip. Never double.
-
Should I stay on a lower dose of a GLP-1 if it’s working?
Often yes, if it is a labeled maintenance dose: Zepbound 5 mg and Wegovy 1.7 mg count. Starter doses do not. The call is your prescriber’s.
-
Best time of day to take a GLP-1: morning or night?
Weekly GLP-1 shots work the same at any hour; pick one you won’t miss. The Wegovy pill and Rybelsus are taken on waking on an empty stomach.
-
Headache on injection day of a GLP-1: is it normal?
Common. Headache is on the Wegovy label, and most shot-day headaches trace to skipped meals, too little fluid or less coffee than usual.
-
Injection site reactions on a GLP-1: redness, lump, bruise, itching
Redness, a small lump, a bruise or itching where you inject a GLP-1 is common and usually fades. What causes each, what helps, and what needs a call.
-
Left a GLP-1 out of the fridge: is it still good?
Usually, if it never froze or went above 86°F and is within its label’s days out: 21 for Zepbound and Mounjaro pens, 28 for Wegovy pens, 56 for Ozempic.
-
Can I take a GLP-1 a day early?
Usually yes, once: labels allow a new shot day if doses are 2+ days apart (semaglutide) or 3+ (tirzepatide). Not every week, and not for daily pills.
-
GLP-1 injection day: tips and what to expect
Injection day starts a curve that peaks 1 to 3 days later. Plan the days after: lighter meals, steady sips, a rotated site, a quieter calendar.

GLP-1 dose increase side effects: what’s normal in the first week
The first week on a higher GLP-1 dose often means a rough day two and three, then a steadier week. What is expected and what is not.
