You need to follow the instructions from your doctor or the package label, and to ask for clarification of any parts that may not be understood. It is essential to take famotidine exactly as prescribed by your doctor, and not to take more or less than directed, or take it more often or for a longer period than recommended.
The dosage and length of treatment are based on your medical condition and response to therapy. In children, dosage may also be based on body weight. For adults and pediatric patients weighing 40 kilograms or more with normal renal function, the recommended dosage of Pepcid 20 mg and 40 mg tablets is applicable.
