Hi

Lanzol is usually given after 1 year of age.
Usual dosage given is 15 mg per day.
Duration of treatment will depend on the response to treatment.

Its is safe.
How ever any medications can have adverse effects especially when given for long term.
It may cause liver enzyme abnormalities, electrolyte abnormalities and effects due to long term suppression of acid secretion.

You have to be on a regular follow up with your doctor to assess the response, to monitor your kid`s growth and to look for any adverse effects.

Along with medications you have to make sure that
- He is kept upright for at least 30 min after feeds.
- Give semi solid and solid food.
- Milk can be thickened by addition of cereals like rice.
- Do not overfeed. Instead give small frequent feeds.

Usually kids outgrow this reflux- as they grow, the tone of the muscle that encircles the junction between stomach and food pipe increases- so reflux becomes less.

Hope my answer helps you.
Wish your kid good health.
