Hello and welcome to Healthcare Magic . From my clinical experience I would like to suggest that you might be suffering fom the adverse effects of Crocin (paracetamol ,generic name-acetaminophen ). Paracetamol is metabolised by the liver and is hepatotoxic; side effects are multiplied when combined with alcoholic drinks, and very likely in chronic alcoholics or patients with liver damage. Prolonged daily use increases the risk of upper gastrointestinal complications such as stomach bleeding,and may cause kidney or liver damage. Dosages exceeding 325 mg of paracetamol should be avoided due to risks of hepatoxicity . Crocin is an antipyretic and analgesic which means it can bring down the body temperature and reduce pains but it is not a treatment for fever .It might be that the general disease is progressing to its next level and you are experiencing the abdominal complications . I recommend visiting your GP and get yourself clinically evaluated for the exact cause of the fever and the GI symptoms . Pantosec -D would help more if you are also experiencing nausea and vomiting and heartburn . I would suggest not to self medicate at this point . Thanks .
