Hi welcome to Health care magic forum. Of course
famotidine have many cardiac side effects, except
hypertension, so need not consider it to be due to hypertension.
The
epigastric pain if due to excess of alcohol consumption it can cause hyper tension as well. So you can attribute it to be due to alcohol.
Even other wise also if there is if you have a hystory of hypertension in the family you can get it some times, when you are in some sort of mental or physical
stress, and comes down when stress is relieved. But it gets stabilised after some time and it continues for life then you have to use the antihypertensives. If the present hypertension is continuing, you should start medicines immediately.
I advise you to
consult a cardiologist for investigation and treatment.
Besides i advise you to follow some diet recommendations as avooid taking spices, chillies, junk foods, oily foods, avoid salt as far as possible. avoid alcohol for life.
Wishing for a quick recovery and thanks for calling.
