This calculator determines the Ranitidine dose for treating conditions like ulcers or GERD, using a concentration of Ranitidine 15 mg/mL, based on the patient’s weight for pediatric patients ≥1 month and a fixed dose for adults:
Dose in mL and mg (based on Ranitidine):
Pediatric ≥ 1 month: 4 to 10 mg/kg/day po BID (Max: 300 mg/day)
Adults: Usual dose is 150 mg PO BID
Where:
Administer as prescribed for ulcers or GERD. ⚠️ Always consult a healthcare provider.
Enter the patient’s weight in kilograms or pounds, select the unit, and click "Calculate." The calculator provides the dose in mL and mg (Ranitidine) for pediatric (≥1 month) and adult patients, ensuring the minimum dose (if applicable) is less than or equal to the maximum dose for pediatric patients.
Example: Weight 12 kg:
Pediatric ≥ 1 month: Min Dose: 1.6 mL (24 mg) PO BID Max Dose: 4 mL (60 mg) PO BID Adults: Usual dose is 10 mL (150 mg) PO BID Calculations must be re-checked and should not be used alone...
Consult a healthcare provider before administering.
Ranitidine (Zantac) is used to treat ulcers, GERD, and other conditions involving excess stomach acid.
Pediatric ≥ 1 month: 4 to 10 mg/kg/day po BID (Max: 300 mg/day). Adults: 150 mg PO BID.
Consult a doctor, as Ranitidine is not typically recommended for infants under 1 month without medical supervision.
Enter the weight in pounds, and the calculator will automatically convert it to kilograms for calculation (1 lb = 0.4536 kg approximately).
The maximum daily dose is 300 mg for pediatric patients (≥1 month) and not specified beyond the usual 300 mg/day for adults (typically managed by clinical judgment).
