My father(age 68yrs) became unconsus four times in the month of Sept.'11 but there was no previous history of such incidence. He is a petient of high BP (160/110). Doctor prescrib him Valparin chrono 500 twice dailly. alongwith lobate 100 (Twice), Losar H (one), Rivotril (one). Now there is no such unconsusnes problem. Blood pressure is also under control (110/70). But he is suffering from stomack problem, sometimes diarrhea, swelling of legs, low back pain. he is now unable to take proper amount of food as he feels tasteless. Can you tell mewhether it is due to side effect of any medicine? or any thing else?
