Mounjaro headache first week

Good morning, first week on 2.5mg and haven't lost anything which is really disappointing as I have been in calorie deficit. Without mounjaro I would have lost 4 or 5 pounds in first week

I have also had the most horrendous headache all week. Nothing is touching it. However, I also have Covid so the headache could be Covid related but I'm sure Covid headaches don't last a week long ?

Anyone else has mounjaro headache and how long did it last ?

I get a headache when I first take my pen each week. Are you keeping hydrated?

Are you feeling effects of the appetite suppression? 2.5mg is just to get you used to the medicine. I’ve read some people don’t loss on it. I did but I quickly had to move up the dozes as the effect wore off after a few weeks. Trust the process.

Thank you. Yes am drinking plenty of water.

I have definitely had appetite suppression.
No other side effects at all. Just the headache which is pretty bad.

But could be a Covid headache ???

I suspect it's as likely to be the Covid as the mj. I get headachey but generally it passes as long as I drink enough.

My weight can be stable for a few weeks and then I get a whoosh effect and loose a few pounds at a time. Start tracking and you’ll notice a difference over time.

MJ won't make you retain weight whilst in a calorie deficit. Have you worked out exactly how many you need to be in a deficit and logged everything meticulously?

LennyBalls · 22/02/2025 10:47

Yes I am using a calorie counter app. Am eating 1200 calories a day.

I had a terrible headache the first week I took MJ in June last year, also had my first ever bout of covid that week too and was in bed for a week - 10lb loss first week loss 🙈.

Could have been either MJ or covid causing the headaches.

Might also have been going cold turkey from sugar, caffeine, etc

Whatever it was, it was only in that first week, haven't had any since.
