Mounjaro side effects.

Boliviabae · 28/06/2025 23:05

I took my first dose yesterday.

I have had severe effects from it all day today. I didn't realise that it would be this bad?

I have had severe nausea all day. I feel like I am going to throw up every ten minutes.

I have had really bad stomach pain.

I have had diarrohea.

I have had constant foul smelling sulphurus burps.

It's been awful.

It's been used for over 20 years, if it wasn't safe, it wouldn't have been used for 2 decades...

As other posters have said, no drug is completely safe.

Other posters on this thread wrote that they had to stop taking it, due to serious side effects.

Which is fine. All drugs have side effects. They're still safe.

No they are not!

What do you mean by your definition of "safe".

My mother took mounjaro earlier this year and she became severely sick. She was severely dehydrated.

It had a very negatjve effect on her. It wasn't safe for her at all

Looking at this forum, lot of posters have written that they have had serious side effects after taking mounjaro.

It seems like there is more debilitating side effects with this drug, then there are with many other drugs.

Oh well in that case let's never take any medicine again.
Even bloody Calpol can be unsafe if you look at this way, yet we give it to babies...

It is important that people talk about serious side effects that they are going through.

So other people can make an informed choice before they take it.

It's people like you that want to brush it under the carpet...

Honestly @Boliviabae I’m not sure why you have decided to take it? You clearly have concerns about its safety, as far as I can see from your posts you haven’t been prescribed it for diabetes, so it was an active decision on your part to deliberately seek out and get a prescription for Mounjaro.

What are you on about?
Of course I haven't taken it for diabetes

. We are on the weight loss forum, and everyone on here, including myself has taken it to lose weight.

I didn't have concerns about it's safety until after I took it. It has made me the sickest that I have ever been in my life.

Now I have concerns, after taking it.

Of course it is but that doesn't mean the medicine is unsafe to be prescribed.

Paracetamol has side effects including raised heart rate and blood disorders. But the medicine is still safe for the population.

I never said that it was unsafe to be prescribed.

I said that i think it's unsafe for me due to the very serious side effects that i have gone thriugh.

I think its unsafe for my mother, who became extrenely ill after taking mounjaro earlier this year.

And I think its unsafe for the posters on this frum who have suffered severe side effects.

There are a small proportion of users who report significant side effects such as yours. There are a huge proportion of users who report mild or no side effects. I’m sorry you and your mother have both been in the former category, but this does not contradict that for most people it’s completely safe and the positives massively outweigh usually minor side effects.

No one is disputing that you are unwell because of your (rare) extreme side effects and several of us have made suggestions of how you might limit or improve these going forward. You seem more bent on making this thread a warning that it is likely to happen, which is sinply not the case for the vast majority of people.

Have you considered any of the advice? Considered what you ate before taking it or what you could do now to remedy the side effects? Or just here to rant about how it’s unsafe and try to put others off taking it?

InfoSecInTheCity · 29/06/2025 09:34

You’ve taken one dose and felt nauseous for 24 hrs, you haven’t said that you’ve actually been sick, you’ve just felt a bit sick. If that’s the sickest you’ve ever been in your whole life then maybe your threshold is low.

you haven’t answered the questions about what you’d eaten prior to taking the jab, it could very well be that this is just a simple and temporary reaction to the combination of the food you had undigested in your system and taking a medication which slows down that digestion.

It is medication, it can cause side effects, the effects you’ve described are well known, detailed in the leaflet and spoken about readily, the effects can be mitigated by eating the right foods and drinking plenty of water.

It is not a small proportion.

There a huge amount of posters on mumsnet who have suffered the same side effects as me.

Read through the threads. My side effects are not rare at all.

Two smoothies and yogurt is definitely not helping. That’s an acidic mixture of nothing but liquid! You need protein

See your last line. That is so nasty. I am not trying to put others off taking it.

Im writing about my very real experiences.

Its important that people write the truth of what they go through.

I never get side effects from medication... But
...

Now very worried 😫

I have been on it a year, 5 stone down. Eat sensibly and you will be fine.

Boliviabae · 29/06/2025 09:44

I won't be on this thread anymore today because i am going for a lie down, because i feel so sick.

PhilosophicalCheeseSandwich · 29/06/2025 09:47

Either you do think it's safe and those who have a significant reaction are outliers (seems you do seeing as you say you went on to try it after your mum was very ill on it). Or you have an axe to grind for some reason and want to stop people taking it (why would you?). Which is it?

BiscuitBotherer · 29/06/2025 09:47

@perimenopoppet I thought exactly the same thing when I read the OP’s first few posts. It all just sounds like an attempt to put people off MJ. I very much doubt the OP did any actual research and is clearly not eating properly throughout.

BiscuitBotherer · 29/06/2025 09:49

@Boliviabae You took your first dose yesterday. Stop scaremongering.

I’m sorry you took it that way and perhaps I could have worded it better. Perhaps it was my frustration at you not acknowledging the many supportive suggestions I and many others have made in our previous posts but continuing to state over and over that it’s unsafe.

I genuinely hope you feel better soon and take some time to read the support provided to you, and try some of the suggestions so that you are able to move past this and enjoy the countless benefits of this life changing medication. I imagine you are scared and angry and I have sympathy that you can’t think straight when you’ve been as ill as you describe. It is important that you have highlighted that this is possible and no one should enter into this without knowing it could also happen to them.

As the latest post from a new user shows you are scaring people and that’s not what this is about. By all means raise awareness that it’s a rare possibility that you could be quite unwell and ask for help which you did and it’s been given, but now try to focus on the ways you can make yourself well again.

Edited

Anecdotes are not the same as actual data. No-one is saying there are side effects. But the medicine is safe, otherwise the NHS wouldn't have been prescribing it for over 20 years.

Catsinaflat · 29/06/2025 10:00

Fruit smoothies are high in fructose which is sugar. Everything I have read about mounjaro says avoid high sugar and high fat. Have you drunk enough water (2l at least per day). Did your mum drink enough? You need to prioritise protein and fibre.

That sounds wise. Perhaps also go to the chemist for some advice and meds if needed to manage the side effects (or ask someone to go for you) and make a food diary of the 24hours before and after taking your first injection, while offline as suggested to see if there is anything you can change to reduce the issues. Hopefully you can move past this and join the June starters thread for ongoing support in this fab community.

Imagine having the energy and motivation to start a made up thread purely to put people off a weight loss drug.
