I'm supposed to go to the dentist tomorrow for a cleaning, my first visit since valve replacement, and I've been prescribed 4 x 500 mg tabs of amoxicillin to take an hour before my appointment.

I'm very nervous about the appointment. I've read that amoxicillin can pose risk of stroke and I have a history of stroke, so... In addition, the prescription docs note that the risks associated with preventive antibiotics in most patients - adverse reactions and development of drug resistant antibacteria - outweigh any benefits.

I don't even feel safe to take the amoxicillin at home and then drive to my appointment. I'm more inclined to go early to the appointment and take it there. Am I overthinking this??? 🙃
 
I too was nervous about teeth and dental work. I take it before any dental activity that creates a wound; An extraction, or root canal.
But I have not been taking it for any other type of dental maintenance. I have had no issues .

Thanks for the reply. So you've never taken it before a cleaning??

And have you suffered any side-effects from taking it?

Also: What type of procedure did you have done? Valve replacement??

I have been taking amoxicillin for cleanings for 11 years with no issues. However I have no history of stroke.
 
Endocarditis is no joke and I imagine it raises your risk of stroke far, far more than taking a lone dose of amoxicillin.

The timing of the dose is to have it in your system Before the work, right? So taking it late makes no sense to me at all. Reducing your benefit while not changing your risk (which to me you’re overthinking.)

I’ve taken it many times for cleanings (back when it was recommended for some people with native valve disease) and I’ll be taking it again now that I have a mech valve. No side effects. Everyone with mech valves is at risk for stroke and all still recommended for dental premed so this is a known issue built into the recommendations.

The package warning against overuse is for parents insisting on antibiotics for their child’s clearly viral infections. Not for people at risk for endocarditis who need one dose twice a year. They are seeking to keep antibiotics effective FOR YOU.

You always retain choice but I do think you may be in the grip of anxiety and overthinking it. Personally I’d blame myself a lot more for ditching the recommendations and something went wrong than if I followed well established medical advice and something went wrong. You’re not even talking about one doctors opinion here but about written national guidelines.
 
If I’m remembering right, from what I’ve read here on the forum, there have been more horror stories about getting BE from not taking it early enough (say, only taking it 45 minutes before dental work, instead of more than a full hour before) than issues from the antibiotics themselves...

Having said that, I don’t know the stroke risk of those people..

I always took my premed before ‘anything that would cause any bleeding’ - so not initial exams or X-rays.

Having said THAT, if I knew the dental assistant cleaning my teeth was super gentle with the floss (finding someone like this is very rare though, and has only happened to me once) I might risk NOT taking a premed, so as not to have to deal with possible yeast infection-like symptoms later. (Or buying extra probiotics to take after the appointment)

(However, as far as I know, I don’t have a particularly high stroke risk...)

I don’t think this was helpful, but I just wanted you to know someone was listening, and understands well your anxiety about the situation. I’d never heard of amoxicillin increasing stroke risk. Now I’m a little (more) nervous for my next dentist appointment......

I strongly agree with dornole that Endocarditis is dangerous; you want to minimize your chances of getting it.

Amoxicillin is effective over a span of hours, so the timing of your dose can be slightly off, and it will still work.

Good morning
I'm very nervous about the appointment. I've read that amoxicillin can pose risk of stroke and I have a history of stroke, so...
first I've heard of this, so I googled it
I must say that Googles AI overview is pretty good these days (after all the tweaking its been getting)

The references:
https://www.nature.com/articles/s41...n increased risk,associated with a lower risk.

https://pmc.ncbi.nlm.nih.gov/articl...tibiotic,adulthood with subsequent CVD events.

https://www.mdedge.com/cardiology/a...m-antibiotic-use-may-heighten-stroke-chd-risk

I think its pretty important to actually read the stuff which is used as the basis to say "may increase risk" and double down on the word "may" and what the context for that maybe is... I suspect however that such risk is related to long term use, not single administration.

Myself I've taken antibiotics for all dental cleaning since 1990's ... never had a stroke.

I've also had a period of my life (starting a year after OHS#3) where I was on amoxcillin for ten years. Also never had a stroke. I was only on warfarin after OHS#3 (where I got a mechanical) and so that may have helped.
