Thanks for the query.

Pradaxa is dabigatran etexilate mesilyate and a drug approved for AF that you are using.

Post marketing surveiilance reports suggest about 0.06% of people developed vasulitis with use of Pradaxa (13 of 23,498 people on WWW.WWWW.WW , and would think that link is more important than cashew nut intake.

Of course, if cashew nut allergy already exists in the said individual, then the rash if appears within a few hours of nut ingestion, would be consistent with a nut allergic reaction. Antihistamines will be sufficient to control the reaction. Vasculitis is unlikely to occur due to nut allergy/allergic reaction.

However, I do not have personal experience of a nut allergic patient on dabigatran who developed vasculitis while consuming both the food and the drug.

Do get in touch with your Haematologist for some steroid creams for the rash.
Hope I have answered your query. Let me know if I can assist you further.

I am taking Dabigatran 150 mg twice a day. I think I was told not to use antacid tablets as Dabigatran works with acid somehow.

I have just been prescribed a short course of 10 Pantocid 40 mg tablets. I mentioned to my GP that I had a very bad dose of diarrhoea a few days ago but didn't mention acid reflux.

Should I go back to him or is it OK to take these two together?

Hi…..I saw an ad for Pradaxa, but they specifically said it’s NOT for a-fibrillation caused by leaky valves. They said it more than once very clearly, while then going on to explain all the benefits over warfarin, including no blood tests. So I don’t know if mom (84 yo, leaky valves, pacemaker for 5 years) could ever take it…..??

I am 81, I have been on warfarin for four years for atrial fibrulation. I have had no problems until now. My blood is 1.7 (usual reading is 2.5) For four weeks now it has been too thick.I do not know why the blood has thickened. They have altered the dose of warfarin, but the blood is still too thick. I have not been on any other medications. Do not drink alcohol and do not eat too much green veg, so why has this suddenly happened? Please help? many thanks, Peggy
