can i ask why you are taking four ibuprofen a day and if you were advised to do so by a doctor or health care provider? how long have you been taking them? you will need to contact your doctor or health care provider for evaluation. ibuprofen can cause many gastrointestinal side effects and there is a possibility of a link between its use and ulcers. based on your doctor's evaluation they may prescribe a prescription medication that does not have these types of side effects.
