Ranitidine Side Effects
Common side effects of ranitidine include headache, constipation, diarrhea, and upset stomach. Less common side effects may include dizziness, difficulty sleeping, and blurred vision. While most side effects of this drug do not require medical attention, be sure to notify your healthcare provider immediately if you experience heart problems, such as a fast or slow heart rate.
As with any medicine, there are possible side effects with ranitidine hydrochloride (Zantac®). However, not everyone who takes this drug will experience side effects. In fact, most people tolerate ranitidine well. When ranitidine side effects do occur, they are generally minor and either require no treatment or can easily be treated by you or your healthcare provider.
