My mother was having viral fever along with sore throat and cough,we were giving paracetamol,on third night temperature goes till 103 so doctor suggested Meftal 250 mg , on the forth day morning she was having severe stomach pain and excessive gas, and she has fainted and has seizure for few seconds 4-5 seconds, she never have seizure before in life, now she is fine and don't have fever just cough, doctor said it might be due to dehydration or reaction of meftal tablet, does its a matter of serious concern ? Pls suggest if any kind of test required or not ?
