Mounjaro should I start before or after holiday?

I’m due to pick up my first mounjaro prescription on 2.5mg tomorrow but I’m going abroad for a 4 days next Wednesday (so a week from when I do the first injection - then I guess I’ll do another one the day I go). How bad are the side effects in the first two weeks? Should I delay the collection until after I come back? It’s not a relaxing holiday, it’s going to be full on and tbh probably quite stressful with kids!

I never had any side effects at all. And that’s a start dose so is sub therapeutic anyway - I’d get going on it and if it has some small effect on your appetite you can miss a few holiday pounds without trying.

After. I always stay on the same dose if I’m going on holiday. It has a half life of 5 days so the second week of each new dose always has the most impact and side effects for me.

You can collect it now and keep it in your fridge.

Pick up your prescription and pop it into the fridge then wait until after your holiday to start.

Everyone reacts differently so there is no way of knowing if you will suffer side effects and you don't want to urgently need the toilet or feel sick while travelling or on holiday.

Enjoy your holiday and when you get back you will be raring to get started. You could choose to start cutting back a little without the Mounjaro if you are feeling highly motivated or wait until you get back.

Mounjaro (after the first week or two) should help with a healthy rate of weight loss of a pound or two each week. Don't use it to crash diet which could be tempting before a holiday but also could result in muscle loss, hair loss, fatigue, anemia etc.

I would wait till after your holiday. I've had no SE but you might, any fatty, spicy,salty foods seem to be causing upset tummies and nausea and you won't know how foods are cooked, so I'd go have fun and start later. Have a great time

I found 2.5mg quite strong, I took 1.25mg before my holiday - I didn’t lose but I didn’t gain so that was a positive for me. I still had enough appetite to eat but didn’t totally overindulge like I usually would and we ate out alot etc.

You don’t know how your body will react to the medication so it is best to start after your holiday .
