What should you know about infant reflux medicine?

Reflux happens when milk and stomach contents move back towards the food pipe. It is common in young babies because the valve between the stomach and food pipe is still developing. Spitting up is different from painful or complicated reflux: concern rises when feeds are consistently difficult, weight gain is poor, or the baby seems distressed.

A doctor may review the feeding pattern, amount, preparation of formula, position during and after feeds, and the baby’s growth. Medicines that reduce stomach acid do not treat ordinary spit-up and can have unwanted effects, so they are not a routine remedy for every unsettled baby.

Arrange a Child Health Consultation if reflux is affecting feeds, sleep, comfort, or growth. Keep a simple record of feeds, spit-up, crying, wet nappies, and any medicine already tried. Follow the clinician’s instructions exactly if medicine is prescribed; do not use an adult product, thicken feeds, or alter formula without advice.

Offer calm, paced feeds and pause for burping when needed. Keep the baby upright while awake after a feed, but always place the baby flat on their back for sleep on a firm, clear surface. Never prop a bottle or place a sleeping baby on their side or front to control reflux.

Seek urgent medical help if vomit is green or bloody, forceful vomiting keeps happening, the baby is hard to wake, breathing is difficult, the abdomen looks swollen, or there are markedly fewer wet nappies. A baby who cannot keep feeds down needs prompt assessment.

Contact a clinician soon when feeding is repeatedly painful, crying is prolonged around feeds, symptoms are worsening, or growth is a concern. These signs need an examination rather than a medicine decision based on spit-up alone.

Could the feeding pattern, allergy, infection, or another problem explain these symptoms? Does my baby need a medicine, and what benefit should we expect? How should it be given, when should it be reviewed, and which changes mean I should stop and call?
