How Do I Take Tagamet?

When and How to Take Tagamet

Some general considerations for when and how to take the medication include the following:
  • Tagamet comes in tablet form. Depending on the condition being treated, it is usually taken by mouth one to four times a day.
  • For people with difficulty swallowing capsules or tablets, prescription Tagamet also comes in a solution (liquid) form.
  • You may take it with or without food. If you are using over-the-counter Tagamet HB to prevent heartburn, you should take it right before eating (or up to 30 minutes before eating), up to twice a day.
  • If you take Tagamet on a regular basis (not just when you need it), you should take it at the same time(s) each day to maintain an even level of the drug in your blood. If you take it just once a day, it is usually best to take it in the evening or before bedtime.
  • For the medication to work properly, it must be taken as prescribed. It will not work if you stop taking it.


The dosage your healthcare provider recommends will vary depending on a number of factors, including:
  • Your age
  • The medical condition being treated
  • Other medical conditions you may have
  • Other medications you may be taking.
As with any medication, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
