Dosage Guide

Quick Answer

Lansoprazole's standard dose is decided by the doctor according to the condition — generally 15mg or 30mg once daily, 30 minutes before food. In H. pylori therapy it is used twice daily. Swallow capsule whole — do not crush or chew. Never exceed prescribed dose — long-term risks are dose-dependent.

Dose at a Glance

Adult Dose

15mg or 30mg capsule — as prescribed

Once daily, 30 minutes before the first meal; twice daily in H. pylori therapy

Max: Do not exceed the prescribed dose; older adults usually no more than 30mg a day; moderate or severe liver disease usually half the daily dose

Child Dose (Avoid in infants under 1 year)

Not recommended in children because clinical data are limited

Only if a specialist decides it is needed

Missed Dose

If you forget a dose, take it as soon as you remember — 30 minutes before food. If the next dose is soon, skip it. Never take a double dose. Acid symptoms may temporarily return — do not worry, take the next dose at normal time.

Overdose

In case of excessive dosing, contact a doctor or emergency room. Lansoprazole overdose can cause headache, nausea, and abdominal symptoms. Seek emergency help if serious.

Child Dose (Bachon ke liye)

Lansoprazole is not recommended in children because clinical data are limited, and it should be avoided in infants under 1 year. If a child needs it, only a specialist should decide on use and dose — do not calculate it yourself.

Pregnancy and Breastfeeding

As a precaution, it is preferable to avoid lansoprazole during pregnancy. It is not known whether it passes into breast milk, so during breastfeeding your doctor will weigh the benefit to you against the possible risk to the baby.

How to Take (Kaise leni hai)

Take 30 MINUTES BEFORE FOOD — most important point
Swallow capsule whole — do not damage the enteric coating
Take at the same time every day — maintain a routine
If swallowing is difficult, ask your doctor about an alternative formulation

Best Time to Take (Kab leni chahiye)

30 minutes before morning breakfast — for once daily dosing
In H. pylori therapy, the doctor specifies the schedule

With Food or Empty Stomach (Khali pait ya khane ke baad)

Lansoprazole 30 minutes before food — taking it in this window maximises efficacy. Taking it completely on an empty stomach or after food is not ideal. 30 minutes before first meal = best timing.

Missed Dose (Dose chhoot jaye to kya karein)

Take it as soon as you remember — 30 minutes before food. If the next dose is soon, skip it. Continue the normal schedule. Do not take a double dose — acid symptoms may temporarily return but this is expected.

Overdose (Zyada Dose)

If more than the prescribed dose is taken, contact a doctor or the nearest emergency room. Lansoprazole overdose can cause headache, nausea, and GI symptoms.
