There are many lansoprazole-based products available, some of which are available over-the-counter and some which need a prescription. It’s important that you get the right drug for you, and this is where our doctor can help.

By speaking to them about your symptoms, you’ll get expert advice on the most effective way to treat your condition. Lansoprazole is also sometimes mixed with antibiotics to treat certain conditions, which is something you should definitely talk to a GP about before you start.

Taking lansoprazole on the go

Lansoprazole Dosage

There are a number of different ways to take lansoprazole, including a slow-release capsule that you swallow whole, a tablet that dissolves on your tongue, or a liquid.

Lansoprazole normally needs to be taken for a number of days before you start to feel better, while many products are most effective if you take them just before a meal. You should take lansoprazole as instructed by your doctor - don’t stop taking it or change your dosage without speaking to them first.

If you accidentally miss a dose, don’t panic. You can take it as soon as you realise what’s happened, unless of course it’s nearly time for your next dose anyway. In this situation, just skip the one you forgot. You should never take a double dose of lansoprazole.

What Are The Side Effects of Lansoprazole?

Common side effects of lansoprazole include nausea, diarrhoea, constipation and headaches. These are usually mild and nothing to worry about. They’ll go away once you finish your treatment.

You should look out for potentially serious side effects that, while rare, will need medical attention. See a doctor straight away if you get diarrhoea that’s bloody, or very watery.

Long term use of lansoprazole can lead to low magnesium, symptoms of which include heart palpitations, muscle cramps and dizziness. It may also cause low levels of vitamin B12.

You must get emergency medical help right away if you think you’re having an allergic reaction to lansoprazole. Call an ambulance if you’re having trouble breathing, notice swelling around your face and neck, or develop a sudden, severe rash.

Things to avoid

Before you start taking lansoprazole, tell your doctor what else you’re taking, as some drug combinations don’t mix well together and could even be dangerous.

It may not be safe to take lansoprazole if you have:

  • Liver disease
  • Low magnesium levels
  • Osteoporosis

It’s also linked to an increased risk of bone fractures, particularly in older patients. Some brands of lansoprazole are not suitable for people under the age of 18.

If your heartburn has lasted longer than three months, it’s likely being caused by an underlying condition. Lansoprazole won’t be effective here, so you should see a doctor about treating whatever’s causing your heartburn.

Lansoprazole and Alcohol

Alcohol can cause side effects such as drowsiness and dizzy spells when mixed with lansoprazole. If you’re taking lansoprazole with antibiotics, remember that many antibiotics can cause unpleasant side effects when mixed with alcohol.

Alcohol can also make conditions such as acid reflux and stomach ulcers worse.

Is It Safe to Take Lansoprazole During Pregnancy?

Lansoprazole is not thought to be harmful for pregnant women, but it’s advisable to ask a doctor before you start taking it, in order to understand the risks.

There’s a chance that lansoprazole might get into breast milk, so if you’re breastfeeding, you should find an alternative medicine to treat your heartburn.
