Appetite returning in the day or two before your next weekly injection is common and has two ordinary explanations: you are still titrating and have not reached a dose that covers the full week, or you are at the end of the drug's effective window. Both are reasons to talk to your prescriber, and neither is a reason to self-adjust.
Why the last day or two can feel different
These medications are dosed once weekly, and drug concentration is not flat across those seven days. It peaks and then declines. For some people the decline is noticeable near the end of the interval, and appetite is the thing they notice.
That pattern is ordinary. It is not evidence that the medication has stopped working, and it is not by itself evidence that your dose is wrong.
The two explanations worth separating
You are still titrating. The label directs 2.5 mg for four weeks, then 5 mg, then increases in 2.5 mg increments no sooner than every four weeks based on tolerability and response. If you are below a recommended maintenance dosage — 5, 10 or 15 mg — end-of-week hunger may simply mean you have not yet reached the dose that suits you.
You are at a maintenance dose and this is your pattern. Some people experience this at any dose. The question then is whether it is manageable, not whether it can be eliminated.
What to track before your next appointment
A prescriber can do more with a specific pattern than with "it wears off". Note for two or three weeks:
- Which day you inject, and which day the change starts.
- What changes — appetite, food preoccupation, portion size, or something else.
- Whether it resolves after your next dose, and how quickly.
- Your current dose and how long you have held it.
- Whether side effects would allow an increase, if one were offered.
What not to do
Do not split doses or move your injection day to chase the pattern. Do not increase your own dose. And do not add a second GLP-1 product — the label states coadministration with another GLP-1 receptor agonist is not recommended, and a compounded product stacked on a branded one is exactly that.
When it is not the ordinary explanation
If appetite returns dramatically and early, if weight is rising steadily rather than plateauing, or if the change coincides with a new vial or a new supplier, raise it promptly. Compounded preparations vary in concentration between compounders and are not bioequivalence-tested, so a change in supply is a legitimate thing to mention.
