Rantac (Ranitidine) - Dosage for a 9-Year-Old
Average weight at 9 years: ~25-30 kg
Oral Dose by Indication
| Indication | Dose | Frequency | Max |
|---|---|---|---|
| Peptic/Duodenal Ulcer | 2-4 mg/kg/day | Divided into 2 doses | 300 mg/day |

| Erosive Esophagitis | 5-10 mg/kg/day | Divided into 2 doses | 600 mg/day |
Practical Dose Calculation (for ~28 kg child)
- Ulcer / acid suppression: 2-4 mg/kg/day = ~56-112 mg/day → typically 75 mg twice daily
- GERD: 5-10 mg/kg/day = ~140-280 mg/day → typically 75-150 mg twice daily
Available Rantac Formulations
- Rantac 75 mg tablet - standard choice for this age
- Rantac 150 mg tablet - can be halved if needed
- Rantac syrup (75 mg/5 mL) - useful if swallowing tablets is difficult
Key Points
- Give 30 minutes before meals for best effect
- Duration: typically 4-8 weeks for ulcer healing; shorter courses for GERD symptoms
- Note: In 2019-2020, ranitidine was recalled in many countries (including India and the US) due to NDMA (a potential carcinogen) contamination. Famotidine (Famocid/Topcid) is now the preferred H2-blocker alternative. Check whether Rantac is currently available/approved in your region before prescribing.
- Always dose based on the child's actual weight and confirm with a pediatrician.
