If your child has stomach pain, heartburn, or ulcer symptoms, you might have heard about ranitidine. It’s an over‑the‑counter drug that reduces acid in the stomach. Before giving it to a kid, understand how it works, the right dose, and safety tips.
Ranitidine blocks histamine receptors in the gut, which lowers the amount of acid your child’s stomach produces. Less acid means less irritation on the lining, helping heal ulcers and easing heartburn. It starts working within an hour and lasts about 12 hours, so a single dose often covers a whole day.
The key to safe use is weight‑based dosing. Most pediatric guidelines suggest 1 mg per kilogram of body weight, taken once or twice daily. For example, a 20‑kg child would get about 20 mg per dose. Always double‑check the label and ask your pharmacist if you’re unsure.
Avoid giving adult formulations to kids. Pediatric syrups or chewable tablets let you measure small amounts accurately. If you have only tablets, break them into pieces carefully and use a proper measuring device.
If your child’s symptoms last more than two weeks, cause vomiting blood, or are accompanied by severe pain, call a doctor right away. Ranitidine can mask serious problems, so professional evaluation is essential for ongoing issues.
Also watch for signs of an allergic reaction: rash, itching, swelling, or trouble breathing. Those require immediate medical attention.
Most kids tolerate ranitidine well, but some may experience mild headaches, dizziness, or constipation. If you notice persistent diarrhea, stomach cramps, or a change in behavior, stop the medication and talk to your pediatrician.
Rarely, ranitidine can affect liver enzymes or cause low blood counts. Routine check‑ups will catch these problems early if they arise.
Keep the medicine in a cool, dry place away from direct sunlight. Store it out of reach of children—ideally in a locked cabinet. Do not use any medication that looks discolored or past its expiration date.
If you have leftover ranitidine after finishing the course, dispose of it according to local pharmacy guidelines. Never share your child’s dose with siblings or friends.
Ranitidine can be a helpful tool when used correctly. By measuring the dose, watching for side effects, and keeping an eye on your child’s symptoms, you’ll give them relief without unnecessary risk.
