How to get rid off diarrhea and stomach cramps after taking the betahistine dihydrochloride?
Patient: Ive been taking betahistine dihydrochloride 16mg x 3 for just two days, and started to experience gastric problems, starting with nausea, indigestion and then violent vomitting and diorrhea. I have stopped taking them. How long will it take to get out of my system, as I am still suffering with diorrhea and stomach cramps. Doctor: Hello,  Your symptoms seem to be related to side effects of Betahistine hydrochloride. I suggest to stop the medication.  I also recommend to treat the symptoms by taking an over the counter treatment for the diarrhea such as Imodium.   I also suggest to take Pedialyte to prevent dehydration and drink liquids.   Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Dorina Gurabardhi, General & Family Physician
