Quick Summary

Lansoprazole

Type of medicine

Proton pump inhibitor (PPI) that reduces stomach acid.

Active Ingredient

Lansoprazole – a proton pump inhibitor.

When relief starts

Usually two to three days; full benefit can take up to four weeks.

Not Suitable For

People with known allergies to lansoprazole or other PPIs; consult a healthcare professional if you have severe liver problems or if symptoms persist.

Blocking the gastric proton pump (H+/K+-ATPase) to reduce acid production in the stomach.

Lansoprazole for heartburn and acid reflux

Recurring reflux can make everyday meals uncomfortable. The Care Pharmacy offers a confidential online assessment to help you find out whether lansoprazole is an appropriate treatment, with support from our pharmacy team.

15 mg and 30 mg pack options

Both strengths are available in packs of 28. Select a strength to see the total pack price and price per unit. Your prescriber will check the dose and duration against your symptoms, medical history and current medicines.

What to expect

Lansoprazole reduces the acid your stomach makes. Symptoms may begin to improve after two to three days, although full benefit can take up to four weeks. It is not an instant-relief treatment, and a higher strength is not automatically more suitable.

A clear route from assessment to delivery

Complete the online assessment with details of your symptoms and any treatment you have tried. A UK prescriber reviews your answers and may contact you for more information. If suitable and prescribed, your treatment is delivered discreetly.

Using your treatment

Take lansoprazole as prescribed, usually at least 30 minutes before food. Read the leaflet supplied with your medicine. Contact a healthcare professional if symptoms persist or worsen.

What ingredients are in Lansoprazole?

Lansoprazole contains the active ingredient lansoprazole, a proton pump inhibitor (PPI) that reduces the amount of acid produced in the stomach.

In addition to the active ingredient, it may contain inactive components such as sucrose, maize starch, magnesium carbonate, and capsule shell ingredients. These help protect the medicine and ensure effective delivery.

Always check the patient information leaflet supplied with your medication for a full and accurate list of ingredients, especially if you have allergies or sensitivities. If you are unsure, speak to your pharmacist before taking Lansoprazole.

Warnings and precautions

Lansoprazole may not be suitable for everyone. Speak to a healthcare professional before using it if you have liver problems, unexplained weight loss, difficulty swallowing, or persistent stomach pain. These symptoms may require further investigation before starting treatment.

Long-term use of Lansoprazole may be associated with certain risks, including low magnesium levels, vitamin B12 deficiency, or an increased risk of bone fractures. Always use the lowest effective dose for the shortest duration necessary.

If you are taking other medications, including antifungals, blood thinners, or HIV treatments, inform your doctor or pharmacist, as interactions may occur. If you are pregnant or breastfeeding, seek medical advice before use.

What are the side effects of Lansoprazole?

Lansoprazole may cause side effects, although many people use it without significant problems. Common side effects can include headache, diarrhoea, constipation, nausea, or stomach pain. These are usually mild and may improve with continued use.

Less commonly, some people may experience dizziness, dry mouth, or skin rash. Rare but more serious side effects can include severe allergic reactions, liver problems, or persistent gastrointestinal symptoms.

If you experience severe or unusual symptoms, such as swelling of the face or throat, difficulty breathing, or ongoing stomach pain, seek medical advice promptly. Always use Lansoprazole as directed and consult a healthcare professional if you have concerns.

How do I store Lansoprazole?

Store Lansoprazole at room temperature in a cool, dry place, away from direct heat and sunlight. Keep the medication in its original packaging to protect it from moisture.
