Before taking Pepcid, tell your doctor if you have kidney or liver disease, a history of Long QT syndrome, stomach cancer or other problems, or asthma, COPD, or other breathing problems.
Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, and a general ill feeling.
You should not use Pepcid if you are allergic to famotidine or similar medicines such as ranitidine (Zantac), cimetidine (Tagamet), or nizatidine (Axid).

kidney disease;
liver disease;
