can anyone tell me if they have had to take this antibiotic in conjunction with warfarin, i am aware it can cause a bleed and wonder just how likely that is.

i have reported in to my local anticoag clinic and due to holidays they will see me but the antibiotic will be finished by the time of my appointment.  

Any experiences of the two drugs together would help.

    All medications can affect your INR buy not enough to cause a bleed.

      Is your INR usually within its needed range? Your clinic should see you quickly when you report a change of medication. is the doctor who prescribed amoxicillin not able to call you back to check it?

      Rang clinic as soon as i started amoxicillin.  Due to holidays the nurse said see them wednesday for inr check.  Gp does not take anything to do with inr here, its done by specialised inr clinic visits. If you are incapacitated post surgery or something mobile inr nurse comes, but i just have flu so not obviously eligible.

    Are you in the UK? INR testing varies a lot around the country. Some hospital clinics still do it others pass you on when your initial INR has stabilised. In some parts of the country pharmacies now do it. Many GP's want to pass it on as it is so time consuming. The practise I go to has over 300 patients on Warfarin.

    I have to take antibiotics regularly and they always affect my INR. Another good reason for self-testing, which I’ve done for 4 years now. The antibiotics probably won’t have an immediate effect on your INR. But do get first appointment you can next week.

      Thanks, thats what ive done.  Will see what inr comes out at.  Meantime im wondering whether to take full seven days of antibiotics or just use for five days.

    Yes, this can cause blood to thin (hi INR). My Hemotologist said to use ONLY the penicillin family. I have UTI's constantly and had so many hi readings until I found out why.  Good luck.
