What are the side effects of Rabeprazole?

Q: I have skin rashes for many days. As I have acidity, I take rabeprazole 20 mg. Could this be an allergy to this medicine?

A:Rabeprazole may cause the following side effects: headache, upset stomach, diarrhoea, stomach pain, vomiting, constipation, dry mouth, increased or decreased appetite, muscle or bone pain, drowsiness, dizziness, difficulty in falling asleep or staying asleep. Rarely, it may cause the following skin changes: rash, itching, sweating, urticaria (hives), alopecia (hair loss)- but all these side effects are an exception rather than a rule. Also please check if you are taking any other medications concomitantly.
