Fainted after first dose

[Oceangreyscale]

Has this happened to anyone else? It's a bit scary. I'm worried it could be an allergic reaction but then I also hadn't eaten or drunk anything beforehand so could have been low blood sugar/pressure.
Feeling better now although a bit of stomach cramping.

I will call the pharmacy of course but just wondering if anyone had the same thing happen?

That's Mounjaro to be specific.

Speak to your prescriber to see if you should keep taking it

You should be seeking immediate and urgent medical advice if you fainted. Call 999 or at least 111 or go to A and E if you have someone to take you.

No, fainting on Mounjaro isn't normal.

Feeling normal again now so I won't be heading to A&E so sit for 17hrs as a non priority

Up to you but I think you should call 111

Do you normally faint easily? I used to be really needle phobic and build myself up so much I would faint after most injections, it only stopped when I was desensitised to them during a difficult pregnancy in my 30s.

If you were not concerned or very anxious about doing the injection definitely speak to your provider about your reaction.

I have fainted before a couple of times when having blood taken, but don't usually. I was a bit anxious, I've never injected myself before.

So I think probably that plus doing it first thing in the morning without food or drink. I don't have any other signs of an allergic reaction. But I'll still speak to the pharmacist.

Quite extreme

Is it? Oh okay.

Which part? Seeking immediate medical help after you fainted? Calling 999 or 111 atleast? Fainting not being normal on MJ?

What would it have been - lie down and drink water, you should be fine even though I don't know you and there could be several reasons why you lost consciousness?

From MayoClinic:
Fainting might have no medical significance. Or the cause can be a serious disorder, occasionally involving the heart. Therefore, treat loss of consciousness as a medical emergency until the symptoms are relieved and the cause is known.

Ultimately it's OP's call if she's okay with it and is confident it's nothing. That's absolutely fine, but my advice is far from extreme, and it's dangerous and irresponsible to suggest advising to seek medical help after fainting is extreme.

I'm grateful for all advice, thank you. Fortunately I've recently had all possible tests on my heart so I know that's fine.

I've fainted a few times in my life and never felt it necessary to seek urgent medical attention.

The NHS advice is to see your GP

Well Mounjaro works the same as a diabetic jab and lowers your blood sugar. So you’d have low blood sugar from not eating, than low blood sugar from the injection plus the anxiety of having to inject yourself.

id eat before the next dose in a weeks time and see if it happens again. If it does then stop immediately

If the fainting was immediately after the injection I doubt it's the Mounjaro lowering blood sugar that fast, it's not an instant action medication.

Nurse here. Likely a vasovagal response to the injection, especially if nervous, so scary but not dangerous. Contact the prescriber and if they say to keep taking it, then next time make sure you’ve eaten something reasonably recently, inject sitting down and stay sitting for 5 to 10 minutes after injecting or longer if feeling lightheaded. Lots of people react to injections like this and it can be easily managed so, as long as there’s no other reason not to and you want to, no reason not to continue.

How long between injecting and fainting?

That's fine. It's your risk to take and decision to make, but it would be unwise to advise someone else to do the same as you don't know their medical history, which is the point of the advice.

Anyway, OP @Oceangreyscale I'm glad you're fine and all your tests are good. Thanks for the last post, it's reassuring. You know yourself more than we do so I'm sure you're making the decision that's best for you. I hope you continue to feel better and do well on Mounjaro.

Under 5 minutes

I think this is a polite way to say it is anxiety op. When you say you were a bit anxious taking it, is that maybe an understatement in terms of how others would view it?

No I don't think so, but when I fainted after having blood taken and hyperventilated after my BCG at school I also didn't feel massively anxious, on the surface.

It seems to have an instant affect on me.
OP have you contacted the pharmacy? It certainly made me feel light headed.

It isn't a polite way to say it is anxiety. It is a direct way to say it is a vasovagal response, which since similar has happened previously to the OP in response to an injection is probably the correct call.

A leisurely trip to the GP to discuss would be what I would do, personally.

Hey, sorry to hear that happened, sounds scary! I woke up in the middle of the night after my first jab and was shaking/faint - it passed after a while. I spoke to my prescriber and she said it could be to do with blood sugar dipping, or pressure. I've been having electrolytes daily and keeping blood sugar stable especially around jab day.
Hope you feel better soon!

Reminds me of the delayed fainting I had after a vaccine in school many years ago.

Worked myself up so much, then when I had the jag it was painless and easy. Went back to biology class, so relieved, high stools in the lab and fainted a few minutes after sitting back down, cracking my head of the back of the bench behind me, blood everywhere 🙈

You know you best, does it feel like it was just the pressure/fear of that first injection abating and you feel ok now? I remember feeling very shaky after my first couple too. If it was me I would just keep a close eye on myself for the rest of the day, but if you have any concerns or feel unwell at all speak to someone immediately.

Injecting does get easier to do as the weeks progress.

vasovagal is absolutely due to stress and anxiety.

Stress and anxiety can trigger vasovagal but it can also be due to a heart rhythm problem on its own.
