More information about Lansoprazole

What is Lansoprazole?

Lansoprazole belongs to a group of medicines called proton pump inhibitors (PPIs). These lowers stomach acid levels by inhibiting (or stopping) certain enzymes in the stomach lining from producing acid.

As well as being commonly used to treat heartburn, Lansoprazole can treat other acid-related problems including:

  • gastroesophageal reflux disease (GORD)
  • stomach ulcers
  • oesophagitis
  • stomach infections (when taken alongside antibiotics)
  • Zollinger-Ellison syndrome (a rare condition caused by a tumour in the pancreas)

Lansoprazole comes as dispersible tablets (which dissolve in water) or capsules that are swallowed whole. They are a prescription-only medication (POM) and can only be taken with your doctor’s permission.

How does it work?

Lansoprazole, like other proton pump inhibitors, works to treat gastric issues like acid reflux by lowering the amount of stomach acid you produce.

Proton pumps are enzymes found in the lining of the stomach. They are responsible for producing stomach acid to help digest food.


By taking Lansoprazole, you inhibit (or stop) these enzymes from producing as much acid. This can relieve indigestion and heartburn, as well as other issues where stomach acid causes irritation, discomfort or burning sensations.

How do I use Lansoprazole?

You should always follow your doctor’s instructions when taking a newly prescribed medication. However, a recommended guide for taking Lansoprazole is as follows.

For best results, Lansoprazole should be taken on an empty stomach, 30 minutes before a meal. Make sure to swallow the capsule whole with water as chewing or breaking it can reduce how well it works. If taking a dispersible tablet, place it on the tongue and suck gently until it dissolves.

If you are taking one dose per day, it is recommended that you do so in the morning. If you take two doses, these should be spaced out (in the morning and evening).

Different conditions have different dosage instructions.

Condition Dosage
Heartburn 1 x 15 or 30 mg capsule daily for 4 weeks
Duodenal ulcers 1 x 30 mg capsule daily for 2 weeks
Stomach ulcers 1 x 30 mg capsule daily for 4 weeks
Oesophagitis 1 x 30 mg capsule daily for 4 weeks
Zollinger-Ellison syndrome 2 x 30 mg capsules daily (for as long as your doctor recommends)

If you forget a dose of Lansoprazole, take it as soon as you remember, unless it is close to the time of your next dose. If the latter is true, simply skip the forgotten dose and keep taking your treatment as usual.

What are the precautions?

If you are taking Lansoprazole on a long-term basis, make sure to report any significant side effects or symptoms to your doctor when you have your routine checkups.

If you experience an allergic skin rash while taking Lansoprazole, especially in areas exposed to the sun, you must tell your doctor as soon as you can. This could be a sign that you need to stop treatment. The same goes for any new joint pain or discomfort.

Potential drug interactions

Before taking Lansoprazole, make sure to tell your doctor about any other drugs you are taking. This includes over-the-counter and recreational drugs.

In particular, tell your doctor if you are taking medicines containing any of the following active substances as Lansoprazole may affect the way these drugs work:

The following drugs should not be taken with Lansoprazole:

  • ketoconazole, itraconazole, or rifampicin (used to treat infections)
  • digoxin (used to treat heart problems)
  • theophylline (used to treat asthma)
  • tacrolimus (used to prevent transplant rejection)
  • fluvoxamine (used to treat depression and other psychiatric diseases)
  • antacids (used to treat heartburn or acid regurgitation) sucralfate (used for healing ulcers)
  • a medicine used to treat mild depression (called St John’s wort)

What are the side effects?

Lansoprazole is generally well-tolerated. However, just like any medication, there is a risk of side effects.

It is normal to experience side effects (although not everybody gets them). In the majority of cases, they are mild and go away once you have finished taking the treatment.

Common side effects include:

  • headache
  • dizziness
  • gastric issues (including diarrhoea, stomach pains, constipation, nausea, vomiting, and gas)
  • skin rashes or itching
  • tiredness

Please note: if you experience any dizziness, it is your responsibility to avoid driving or operating heavy machinery for both your safety and others.

For an extended list of side effects, including rare and very rare side effects, please consult the patient leaflet included with your pack.

Who can take it?

Lansoprazole is safe for the majority of people. However, it’s important to consult with your doctor so you know that it’s safe for you.

Lansoprazole is NOT safe to take if:

  • you are allergic to Lansoprazole or any of the ingredients included in this treatment
  • you’ve had an allergic reaction (including an allergic skin reaction) to a different kind of proton pump inhibitor in the past
  • you are taking a medication for HIV called Atazanivir

Speak to your doctor before taking Lansoprazole if you have serious liver disease. They may need to adjust the dose to ensure that this medication is safe for you to take.

Lansoprazole FAQs

Can lifestyle changes help with my condition along with taking Lansoprazole?

Yes, making lifestyle changes can support your Lansoprazole treatment. Avoid fatty or spicy foods in large quantities and don’t lie down right after a meal. Reducing stress levels may also improve your condition.

Are there any foods or drinks I should avoid while taking Lansoprazole?

It's advisable to avoid foods and drinks that increase stomach acid or irritate the oesophagus. This includes spicy foods, citrus fruits, chocolate, caffeine, and carbonated beverages.

Can I consume alcohol while taking Lansoprazole?

While moderate alcohol consumption may not directly affect Lansoprazole, it can worsen acid reflux and other related symptoms. Limiting or avoiding alcohol is generally recommended.

Can I take Lansoprazole with antacids?

Yes, you can take antacids with Lansoprazole. Just make sure to space them out, ideally taking antacids at least an hour after Lansoprazole.

Can Lansoprazole cause weight gain or weight loss?

Lansoprazole is not typically associated with significant weight gain or loss. However, changes in appetite or digestive issues might indirectly affect weight.

Is it safe to drive or operate machinery after taking Lansoprazole?

Lansoprazole doesn't usually affect the ability to drive or operate machinery. However, if you experience side effects like dizziness, avoiding these activities is best.

Can pregnant or breastfeeding women take Lansoprazole?

Pregnant or breastfeeding women should talk to their doctor before taking Lansoprazole. Its safety during pregnancy and breastfeeding isn't fully known. Your doctor can help weigh the risks and benefits to decide what's best for you and your baby. Always prioritise safety for both mother and child.

Can I take Lansoprazole with antibiotics?

Yes, Lansoprazole can be taken with certain antibiotics. This combination is often used to treat H. pylori bacterial infections in the stomach. However, always inform your healthcare provider about all your medications to ensure no harmful interactions.

Is it safe to take lansoprazole long-term?

While Lansoprazole is generally safe for long-term use under medical supervision, there are potential risks. These include an increased chance of bone fractures, vitamin B12 deficiency, and possible changes in the stomach lining. Regular follow-up with a healthcare provider is essential to monitor for any adverse effects and to assess the ongoing need for treatment.

What should I do if I miss a dose of Lansoprazole?

If you miss a dose of Lansoprazole, take it as soon as you remember. However, if it's almost time for your next dose, skip the missed one and resume your regular dosing schedule. Don't take a double dose to make up for the missed one.

Can I stop taking Lansoprazole suddenly?

When considering stopping Lansoprazole, it's not advised to do so suddenly, especially after long-term use. Stopping abruptly can increase stomach acid, making symptoms worse. For a safe approach, consult your doctor. They can guide you on gradually reducing the dose to avoid any discomfort. Remember, following your doctor's advice is key to effective treatment.

What should I do in case of an overdose?

In case of a Lansoprazole overdose, immediately seek medical help. Symptoms may include confusion, drowsiness, blurred vision, and a fast heartbeat. Bring the medication container to assist healthcare professionals and follow their advice closely. Avoid self-medicating and monitor for any delayed symptoms.

How should I store Lansoprazole?

Store Lansoprazole at room temperature, away from moisture and heat. Keep it out of reach of children and in its original packaging.
