Let's take a minute to talk about your medication.

This is famotidine. 

Famotidine reduces excess acid in your stomach, so it can prevent and treat stomach ulcers.  It can also reduce acid in your throat to relieve heartburn, sour taste, trouble swallowing and other symptoms.

Most people tolerate famotidine well, and it is considered generally safe.  Still, some people may have headaches, dizziness or constipation.  This is normal and should go away.  If these or other side effects become reasons you want to stop taking this medication, please talk with your doctor or pharmacist.

Some over-the-counter medications contain famotidine or similar medications, so talk to your pharmacist before taking any of those to make sure they don't interact.

For best results, take famotidine as long as prescribed, and follow the acid-reducing diet and activities recommended by your doctor.
