The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Famotidine comes as a tablet that is usually taken by mouth 1 to 4 times daily, with or without food. Most conditions improve within 4 to 8 weeks and so the medication may be stopped at that time.

The suspension form should be shaken well before each use and unused liquid should be thrown away after 30 days.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of famotidine at the same time.

Take famotidine exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

Most ulcers will heal within 4-8 weeks and famotidine treatment can be stopped. For patients with severe cases this may be extended up to 12 weeks.

Reduced dosages may be required in younger patients or in those with moderate to severe kidney disease.

For active peptic or gastric ulcers (ulcers in the small intestine or stomach):

• A typical starting dose is 40 mg once a day at bedtime.
• This can be split into 20 mg twice a day.
• Maintenance therapy of healed ulcers is typically 20 mg once daily at bedtime.

For reflux disease (GERD):

• A typical starting dose is 20 mg twice a day for up to 6 weeks.
• This may be increased to a maximum of 40 mg twice a day for up to 12 weeks depending on the severity of the condition.

For hypersecretory (extremely high amount of excretion) diseases such as Zollinger-Ellison Syndrome:

• Typical starting dose is 20 mg every 6 hours.
