A person's age is among the factors that can affect Pepcid dosing. For example, the recommended Pepcid dosage for treating gastroesophageal reflux disease (GERD) in adults is 20 mg, taken twice daily for up to six weeks. However, for children ages 1 to 16, the recommended Pepcid dose for treating GERD is 0.5 mg per kg (about 0.23 mg per pound), taken twice daily, up to a maximum of 40 mg twice a day. Also, the recommended Pepcid dosage for treating ulcers in adults is 40 mg daily, while the Pepcid dosage for treating ulcers in children ages 1 to 16 is 0.5 mg per kg per day (about 0.23 mg per pound per day).
The dose of Pepcid® (famotidine) that your healthcare provider recommends will vary depending on a number of factors, including:
- Your age
- The medical condition that you are being treated for
- Other medical conditions you may have
- Other medications you are currently taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
