Hello, I have just discovered i have been taking an overdose of benadryl plus, unintentionally. I didnt read the pack and just took 2 capsules instead of one. On monday i took 9 tablets, Tuesday i took 4 and today I took 3. which totals up to a scary 16 capsules over 3 days! on Monday night i had very bad stomach pains and after going to the toilet about 3 times, i finally had diarrhoea which relieved the pain for the rest of the night. I took colpermin tablets for IBS, assuming that was the problem and went to sleep, the next day I did more diarrhoea once and had a few more pains. Once I realised that I had been overdosing in benadryl, i looked online at symptoms and i have had the drowsiness, diarrhoea, stomach pains, feeling sick but not actually being, dry mouth, fast heart rate and i have just generally not felt my self since. What do you recommend I do because now i dont actually feel seriously ill, just feel sick and drowsy and have occasional stomach pains. Please let me know! Thanks! Lilah Cowley Is there anyway i can get this answer without paying please?
