Acid is produced naturally in your stomach to help you digest food and to kill bacteria. This acid is irritant so your body produces a natural mucus barrier which protects the lining of your stomach. In some people this barrier may have broken down allowing the acid to damage the stomach causing inflammation, ulcers and other conditions. In other people there may be a problem with the muscular band at the top of the stomach that keeps the stomach tightly closed. This may allow the acid to escape and irritate the oesophagus. This is called 'acid reflux' and can cause heartburn and/or oesophagitis.
Proton pump inhibitors such as lansoprazole stop cells in the lining of the stomach from producing too much acid. This can help prevent ulcers from forming or assist the healing process. By decreasing the amount of acid, they can also help to reduce acid reflux related symptoms such as heartburn.
Lansoprazole is also used to treat irritation and ulceration of the stomach caused by non-steroidal anti-inflammatory drugs (NSAIDs). It can also be used as one part of a treatment to get rid of Helicobacter pylori, a bacterium found in the stomach which can cause ulcers.
Before taking lansoprazole
Before taking lansoprazole make sure your doctor, dentist or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have liver problems.
- If you have any of the following symptoms: bleeding, difficulty swallowing, being sick frequently, or unexplained weight loss.
- If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to this or any other medicine.
How to take lansoprazole
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take lansoprazole exactly as your doctor has told you.
- Try to take lansoprazole at the same time each day to avoid missing any doses. The usual dose is once a day in the morning. However, if you are taking lansoprazole for Helicobacter pylori eradication, you will be told to take two doses a day - one in the morning and one in the evening.
- Take each dose at least 30 minutes before a meal.
- Do not take indigestion remedies 2 hours before or after you take lansoprazole as they may interfere with the way lansoprazole is absorbed by your body.
- If you have been given capsules, you should swallow these whole with a drink of water. Do not chew, crush or open the capsules.
- If you have been given orodispersible tablets (FasTabs®), you can place these on your tongue and suck to disperse the granules before swallowing, or you can stir them into water before swallowing, or you can swallow them whole with a drink of water.
- If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Smoking increases the amount of acid produced by the stomach and will aggravate your condition. If you smoke, talk to your doctor or pharmacist about quitting.
- Try to avoid foods and drinks that may upset your stomach such as alcohol, citrus fruits/juices, drinks containing caffeine, tomatoes and spicy food.
- Try to keep your regular appointments with your doctor. This is so your progress can be monitored.
- Recent studies suggest that there may be a slight increase in the risk of bone fractures when proton pump inhibitors like lansoprazole are taken for longer than a year. If this affects you, speak with your doctor to check that you are taking enough vitamin D and calcium to reduce this risk.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking lansoprazole.
- If you buy any medicines, check with a pharmacist that they are safe to take with lansoprazole.
