Pepcid (famotidine) can generally be taken up to twice a day — once in the morning and once at night — for up to 14 days if treating heartburn symptoms. For other acid-related conditions, a healthcare provider may prescribe different dosages and durations. The maximum OTC dose is usually 40 mg per day, and it should not be used more frequently or for longer than recommended without consulting a doctor. If symptoms persist beyond 14 days, see a healthcare professional for further evaluation.

Typical Dosage Frequency

• For occasional heartburn: twice daily (morning and night).
• For chronic conditions like GERD or ulcers: may be prescribed up to four times daily (every 6 hours).
• Do not exceed 2 tablets (maximum 40 mg) per 24 hours OTC.

Duration of Use

• OTC use: up to 14 days.
• Longer use requires medical supervision.

Additional Notes

• Can be taken with or without food.
• Take 10 to 60 minutes before a meal to prevent heartburn.
• Consult a healthcare provider if symptoms continue or worsen after 14 days.
