Doctors may prescribe Zantac for kids with heartburn. This medication belongs to the group of H2 blockers that prevents excess production of stomach acid. But does Zantac for babies work the same way? Zantac is the brand name of ranitidine (generic name), which is also available over the counter. Though you should give Zantac syrup to babies as per the pediatrician’s recommendations, you can read on to know if it is safe to treat heartburn and if it has any side effects.
What Is Zantac?
Zantac is the brand name for the generic antacid compound called ranitidine (1). Ranitidine is a type of histamine-2 (H2) blocker and is particularly used to suppress the stomach cells from producing excess acids and thus prevent heartburn.
Can A Baby Have Zantac?
Yes, babies can have ranitidine (Zantac), but only on a doctor’s prescription (2). Never give Zantac to babies and toddlers unless advised by a pediatrician. When administered in the right dosages, Zantac can be effective and not have any side-effects.
What Is The Right Age To Give Zantac?
Zantac is usually prescribed to babies of at least a month old (3). A pediatrician will explore non-pharmacological treatment, change in maternal diet, and other safer medical alternatives when the baby is less than a month old.
What Is Zantac Used For In Babies?
- Acid reflux or gastroesophageal reflux. In this condition, the lower esophageal sphincter present at the junction of esophagus and stomach does not shut completely and allows some stomach acid to flow upwards towards the mouth. Ranitidine subdues the secretion of stomach acid, thus providing relief from acid reflux.
- Gastroesophageal reflux disease (GERD). When acid reflux becomes chronic, it is called GERD. Zantac provides relief from GERD by preventing excess acid accumulation in the stomach.
- Esophagitis. It is the inflammation of the inner lining of the esophagus caused due to several reasons including GERD. Ranitidine is found to be effective in the treatment of this condition as well.
What Is The Dosage Of Zantac For Babies?
Usually, about 1-2mg of Zantac per kg of the baby’s weight is the prescribed single dosage. No more than two to three such doses are to be given in a day (6).
For example, if the baby weighs about 10kg, he will get about 20mg (2mg x 10kg) of Zantac per dose, which amounts to about 60mg of Zantac in a day, in three doses.
Note that the dosage and duration can vary due to several factors such as the age of the baby, and the severity of the condition. The doctor will also let you know the best time to give the medicine (full stomach or empty stomach) and if the medicine can be combined with other medication (like gas drops or antacid).
Dosage form of Zantac:
Zantac is available in the form of syrup or effervescence tablet for babies. Syrups are easy to administer to older infants who may like the slightly sweet taste. Younger infants could be given effervescent tablets that dissolve in water. The water can be administered to the baby through a dropper syringe.
How Long Does It Take For Zantac To Work In Babies?
The time taken for the medicine to work depends on the severity of baby’s reflux. Ideally, a baby should get relief from reflux and GERD within two weeks from the day Zantac was first administered.
Are There Side-Effects Of Zantac On Babies?
Yes. Side-effects of Zantac include:
- Lethargy and excessive sleepiness
The side-effects are not many and usually disappear once the medicine has been discontinued.
The negative effects are significant among less than 2% of patients who take the medication (10). However, some may experience a few long-term side-effects of using the medicine.
Long-term side-effects of Zantac in babies:
Ranitidine seldom has any long-term effects on the baby’s health. However, if the baby is regularly given Zantac or if there is an overdose of the medication, then the baby runs the risk of the following long-term side-effects:
- Repeated stomach infections: Ranitidine suppresses the stomach acid that plays a vital role in destroying pathogens. Extended consumption of Zantac can increase the risk of infection due to lower acid production (11).
- Necrotizing enterocolitis: It is a condition where bacteria destroy the walls of intestines, leaving perforations/holes in the intestinal walls. Stool and semi-digested food spill out from such holes into the abdominal cavity causing severe infection (12). While the exact reason for this condition is not known, some studies have shown that increased use of H-2 blockers, such as ranitidine (Zantac), in babies can put them at risk of necrotizing enterocolitis (13).
- Liver function problems: Excessive use of the drug may decrease liver capabilities, leading to complications and susceptibility of the liver to diseases like hepatitis. Liver problems due to ranitidine occur in one among 1,000 patients (10).
- Neuropsychological problems: Complications include chronic disorientation, confusion, delirium, and hallucinations. However, these side effects happen in less than 1% of ranitidine users and usually only among those infants who are critically ill and on multiple medications.
- Cardiovascular problems: This is an extremely rare side-effect of ranitidine, which affects one in a million patients and only due to rapid dosage or overdose of ranitidine. Problems of the heart include abnormal heart rate, either too many or too few heartbeats than the average.
What If The Baby Is On Zantac But Still Spits Up?
If your baby continues to spit up despite using Zantac, then take him to the doctor immediately. This could indicate some other underlying condition or infantile diseases such as pyloric stenosis that causes the baby to spit up (14). Get your baby checked by a pediatrician in case of chronic spit ups that do not stop even with ranitidine.
Frequently Asked Questions
1. Is Zantac Same As Prilosec And Prevacid?
Zantac is different from Prilosec and Prevacid. Prilosec is the brand name for the generic compound called omeprazole and Prevacid is the brand name for lansoprazole. Both omeprazole and lansoprazole belong to the compound group called proton-pump inhibitors, also used for treating acid reflux (9), while ranitidine (Zantac) is an H2 blocker. They act differently.
2. Does Zantac Help With Gas In Babies?
There is no evidence that Zantac can provide babies relief from excessive gas. It may help ease the gas caused by acid reflux, but it does not treat gas directly. Ranitidine is primarily prescribed for GER and GERD.
Ranitidine is less likely to cause serious side-effects that have a long-term effect on the baby. Despite that, a baby’s doctor will choose Zantac as a last resort – when nothing seems to ease a baby’s reflux. Experts state that Zantac is safer than alternative medicines, but more research is needed to learn its true effects. For the safety of your infant, use Zantac only as and when prescribed by the pediatrician.

Zantac for babies should be given if the pediatrician recommends it. These are H2 blockers that suppress stomach acid production, thus relieving heartburn. It is available in syrup and tablet forms. Syrups or effervescent tablets that dissolve in water after dissolving are given through droppers for babies. Side effects are less common if given the right dosages according to the baby’s weight, age, and other factors. Never give a portion of adult zantac medications to babies since the composition may vary and often causes adverse effects.
