All medicines have risks and benefits. Your doctor has weighted the risks of you taking SOLOX with the benefits they expect it will have for you.

If you have concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with your medicine . You may need to read it again.

What SOLOX is used for

The name of your medicine is SOLOX. It contains the active ingredient lansoprazole. SOLOX belongs to a group of medicines called proton pump inhibitors (PPI's). SOLOX works by decreasing the amount of acid the stomach produces, to give relief from symptoms and allow healing to occur.


SOLOX is used to treat or help heal peptic ulcers of the stomach and duodenum. These can be caused in part by too much acid being made in the stomach. SOLOX is also used to help stop duodenal ulcers coming back.

Reflux Oesophagitis

SOLOX is used to treat reflux oesophagitis or reflux disease. This is caused by "washing back" (reflux) of food and acid from the stomach into the oesophagus. Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Helicobacter pylori

SOLOX can also be used in combination with certain antibiotics to help get rid of H. pylori infections in certain people with ulcers or chronic gastritis. H. pylori is a bacteria which is associated with the development of ulcers.

Your doctor may have prescribed it for another reason. SOLOX is only available with a doctor's prescription. Ask your doctor if you have any questions about why this medicine has been prescribed for you.

SOLOX has not been shown to be addictive.

Before you take SOLOX

When you must not take it

Do not take SOLOX if:

If you are not sure whether you should start taking SOLOX, talk to your doctor.

Do not use it after the expiry date (EXP) printed on the pack . It may have no effect at all, or worse, an entirely unexpected effect if you take it after the expiry date.

Do not use SOLOX if the packaging is torn or shows signs of tampering.

Before you start to take it

You must tell your doctor if you have allergies to:

  1. Other medicines
  2. Other substances, such as foods, preservatives or dyes.

If you have not told your doctor about any of the above, tell him/her before you start taking SOLOX.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop. Some medicines may interfere with SOLOX or vice versa.

These include:

These medicines may be affected by SOLOX, or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor or pharmacist can advise you on this.

How to take SOLOX

How much to take

Take SOLOX only when prescribed by your doctor. Your doctor will tell you how many capsules you will need to take each day. This depends on your condition.

Carefully follow all directions given to you by your doctor. They may differ from the information contained in this leaflet. If you do not understand the instructions, ask your doctor or pharmacist for help.

Reflux oesophagitis:

30 mg lansoprazole once daily for 4 weeks. If you are not fully healed within this time your doctor will prescribe a second 4-week course of SOLOX. To prevent relapse, your doctor may suggest a maintenance dose of 15 mg daily. Your doctor will tell you the duration of treatment. Do not interrupt or stop your treatment.

Duodenal ulcer:

30 mg of lansoprazole once daily for 4 weeks. To prevent relapse, your doctor may suggest a maintenance dose of 15 mg once daily. Your doctor will tell you the duration of treatment. Do not interrupt or stop your treatment.

30 mg of lansoprazole once daily for 8 weeks.

Eradication of H. pylori:

How to take it

Swallow SOLOX capsules whole with a full glass or water or other liquid.

Do not chew the capsules.

How to open the capsule blister

Remove an individual capsule blister by cutting or tearing along the perforations. Remove the capsule by peeling back the top layer from the opposite end to the lot number and expiry date.

When to take it

Take your SOLOX at about the same time every day. This will help you remember when to take the capsules.

How long to take it

Take SOLOX for as long as your doctor recommends. Your doctor will monitor your condition and adjust your treatment as needed.

If you forget to take it

Take it as soon as you remember, and then go back to taking it as you would normally. If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take SOLOX, ask your pharmacist for some hints.

If you take too much (Overdose)

Immediately go to the Accident and Emergency at your nearest hospital or telephone the New Zealand National Poisons Information Centre (telephone 0800 POISON or 0800 764 766) if you think that you or anyone else may have taken too much SOLOX.

Do this even if there are no signs of discomfort or poisoning.
You may require urgent medical attention.

While you are using SOLOX

Things you must do

Use SOLOX exactly as your doctor has prescribed.

Tell your doctor if you become pregnant while taking SOLOX. SOLOX may affect your developing baby if you take it during pregnancy.

Also tell your doctor if you are breast-feeding or intend to breast feed. SOLOX passes into breast milk and could affect your baby.

Tell your doctor or pharmacist that you are taking SOLOX if you are about to start taking any other medicines.

Things you must not do

Do not give SOLOX to anyone else, even if they have the same condition as you.

Do not stop taking it or change your dose unless your doctor tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how SOLOX affects you.

SOLOX may cause dizziness or light-headedness in some people, especially after the first dose. Make sure that you know how you react to SOLOX before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.

If you drink alcohol, dizziness or light-headedness may be worse.

Things that may help your condition

Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

Side Effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SOLOX.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you have any of the following and they worry you:

These side effects are usually mild.

Rarely, more serious side effects may occur. If any of the following happen, stop taking SOLOX and tell your doctor immediately or go to the Accident and Emergency at your nearest hospital:

The above side effects are serious and also rare. If you experience any of these side effects you should seek urgent medical attention.

Tell your doctor if you experience anything else that causes you pain or discomfit.

As natural acid in the stomach helps to kill bacteria, the lowering of acid by acid-reducing drugs such as SOLOX may make some people have certain stomach infections. If you suffer from severe persistent diarrhoea and/or vomiting when taking SOLOX, tell your doctor.

Other problems are more likely to arise from the ulcer itself rather than the treatment. For this reason, contact your doctor immediately if you notice any of the following:

Do not be alarmed by this list of possible side effects. They do not occur often and you are unlikely to experience any of them.

After using SOLOX


Keep your capsules in a cool, dry place where the temperature stays below 25°C.

Do not store SOLOX in the bathroom or near a sink or window.

Do not leave SOLOX in the car on hot days. Heat and dampness can destroy some medicines.

Keep your capsules in the pack until it is time to take them. If you take the capsules out of the pack they will not keep well.

Keep SOLOX where young children cannot reach it. It is a good idea to store medicines in a locked cupboard at least one-and-a-half metres above the ground to ensure children cannot take them.


If your doctor tells you to stop taking SOLOX, ask your pharmacist what to do with any capsules that are left over.
