GERD Home > Zantac for Babies

Zantac is licensed to treat several conditions in adults and children, including ulcers, erosive esophagitis, and gastroesophageal reflux disease (GERD). There are two forms of prescription Zantac that can be given to babies -- Zantac EFFERdose tablets and Zantac syrup. These products have been approved for use in babies as young as one month old.

Can Babies Use Zantac?

Yes, Zantac® (ranitidine hydrochloride) can be used for babies. Zantac has been approved for use in children and babies as young as one month old. In fact, this medication comes in two prescription forms that are easy to give to babies and children:
  • Zantac EFFERdose® tablets -- Zantac EFFERdose tablets have a light citrus flavor and are designed to be dissolved in water before giving them to your child.
  • Zantac syrup -- Zantac syrup is peppermint-flavored.
Always discuss all medications for your baby with your baby's healthcare provider. Do not give over-the-counter Zantac to babies.

Uses of Zantac for Babies

In children and babies, Zantac has been approved for:
  • Treating ulcers (including duodenal ulcers and stomach ulcers) and preventing these ulcers from returning once they are healed
  • Treating GERD -- GERD is short for gastroesophageal reflux disease (see Infant GERD)
  • Treating erosive esophagitis -- erosive esophagitis refers to damage to the esophagus, often caused by stomach acid.

Zantac Dosage for Babies

The dosing of Zantac for babies and infants is based on their weight.
Zantac Dosing for Ulcers
For the treatment of stomach ulcers or duodenal ulcers in children or babies, the typical dose of Zantac is usually 2 mg to 4 mg per kg (a little less than 1 mg to 2 mg per pound) twice daily. The total amount of Zantac administered per day should not be more than 300 mg (this is only an issue with larger children). For preventing ulcers from coming back once they are healed, the dosage for babies is typically 2 mg to 4 mg per kg (a little less than 1 mg to 2 mg per pound) once a day, but no more than 150 mg per day.
