What does it do?

Lansoprazole is used to treat and prevent some stomach and gut problems, such as indigestion, reflux, and ulcers. It reduces the amount of acid made in your stomach.

How should you take it?

Take lansoprazole regularly as directed with a glass of water. You can take it with or without food, but it may work better if you take it before food.
If you have trouble swallowing you can open the capsule and sprinkle the contents on a small amount of soft food or liquid. Swallow without chewing. Do not crush the capsule contents.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with lansoprazole including:

• iron supplements (e.g. Ferro-Tab®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
