Drug Interactions

Famotidine can potentially interact with a few other medicines (see Drug Interactions With Famotidine).

Are There Alternatives?

Famotidine is quite effective at treating GERD, ulcers, or other digestive problems. It is also generally well tolerated. However, side effects may occur during treatment or the medicine may not work as well as needed. In these cases, your healthcare provider may recommend an alternative. Some examples of substitute medications include:
Other alternatives can include dietary changes (see GERD Diet) and surgery (for more serious problems).

What If I Take an Overdose?

People who take too much famotidine may have overdose symptoms that could include:
  • Vomiting
  • Restlessness
  • Low blood pressure (hypotension)
  • A rapid heart rate (tachycardia).
If you happen to take too much, seek immediate medical attention.

How Should Famotidine Be Stored?

All forms of famotidine (including the liquid suspension) should be stored at room temperature, away from moisture or heat. The medication should also be kept in an airtight container. The suspension is good for 30 days once it is mixed by your pharmacist. After 30 days, it should not be used and should be thrown away.
Keep this and all other medications out of the reach of children.
