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.

Before you start

• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

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.

What side effects might you notice?

Side Effects	Recommended action
Muscle twitching or cramps, tiredness or weakness, tingling or numbness (may be signs of low magnesium)	Tell your doctor

If you notice any other effects, discuss them with your doctor or pharmacist.

Other information:

• Rarely, lansoprazole can cause kidney problems. Often there are no symptoms, but you may feel unusually tired or weak, or have a fever or nausea. Discuss this with your health professional.
• If your symptoms are well managed, talk to your doctor about whether you need to keep taking lansoprazole – they may recommend that you stop it. When you stop you may get symptoms like reflux and heartburn but these should only last for a few weeks. Talk to your health professional if these are troublesome, or if they do not get better.
• Long-term use of lansoprazole may cause bone problems, gut infections, and low vitamin B12. Tell your doctor if you have weak bones (osteoporosis), if you experience severe diarrhoea or stomach cramps or have concerns about vitamin B12. Talk to your doctor about how long you should take lansoprazole for.
