Heartburn

Lansoprazole works by blocking the acid-producing pumps in the stomach lining. By lowering stomach acid levels, it helps prevent irritation and inflammation of the stomach and esophagus, reducing symptoms like heartburn, difficulty swallowing, and persistent cough caused by acid reflux. It also aids in the healing of ulcers and prevents their recurrence, making it a reliable treatment for ongoing gastric conditions.

MEDICATION DETAILS

Description

Lansoprazole Capsules (28 capsules)

Lansoprazole Capsules give longer lasting relief from acid related conditions such as heartburn, acid reflux and stomach ulcers. Lansoprazole is a proton pump inhibitor, or PPI, which reduces the amount of acid the stomach produces, easing discomfort, allowing healing and preventing further irritation. It is a medicine that requires a clinician to assess whether it is suitable for you.

How it works

Acid is produced by pumps in the lining of the stomach. A proton pump inhibitor switches those pumps off at source, which is a different approach from an antacid that neutralises acid already there, or an alginate that forms a barrier. Because it reduces production rather than reacting to what is present, the effect lasts far longer, and it builds over the first few days rather than working on the first dose.

How to use it

Swallow the capsule whole with water, usually in the morning before food, exactly as directed. Do not chew or crush it. Complete the course your clinician has set, even once symptoms settle, particularly if you are being treated for an ulcer. Smaller evening meals, less alcohol and caffeine, and not lying down soon after eating all help alongside.

Who it is for

It is for people where a clinician has confirmed a PPI is appropriate. Your clinician needs to know about liver problems, low magnesium, osteoporosis risk, and other medicines you take, since lansoprazole interacts with several, including clopidogrel and methotrexate.

Safety and when to get advice

Headache, diarrhoea, constipation, wind and nausea are among the reported effects. Long term use is reviewed because of effects on magnesium, vitamin B12 and, with prolonged use, bone health. See a doctor promptly for difficulty or pain on swallowing, food sticking, unexplained weight loss, persistent vomiting, vomit resembling coffee grounds or black tarry stools. Seek emergency help for chest pain with breathlessness or sweating. Our UK pharmacy team can answer questions about this product before you buy.

Common questions

When should I take it?
Usually in the morning before food, following the directions given to you.

How soon does it work?
The effect builds over a few days rather than on the first dose.

Can I take an antacid as well?
Often yes for breakthrough symptoms, but check with a pharmacist about timing.

Always read the patient information leaflet supplied with the pack before use.

Directions

For the best results, take Lansoprazole Capsules exactly as directed. The usual dose is once daily before a meal, preferably in the morning. Swallow the capsule whole with a glass of water—do not crush or chew it. If you have trouble swallowing, some brands allow you to open the capsule and mix the granules with a small amount of soft food or juice. Always follow your doctor's or pharmacist's instructions regarding dosage and duration of use.

Ingredients

Each capsule contains the active ingredient lansoprazole, which belongs to the proton pump inhibitor class of medications. Additional inactive ingredients may vary depending on the brand but typically include substances that aid in capsule formulation and absorption. If you have specific allergies or dietary restrictions, check the ingredient list on the packaging or consult your pharmacist.

Side Effects

As with any medication, Lansoprazole may cause some side effects, although not everyone experiences them. The most common side effects include headaches, nausea, diarrhea, constipation, and stomach pain. Some people may also experience dizziness or dry mouth. Long-term use may lead to more serious effects, such as low magnesium levels or an increased risk of bone fractures. If you experience severe symptoms like persistent stomach pain, unexplained weight loss, or difficulty swallowing, seek medical advice immediately.

Warnings

Before taking Lansoprazole, there are a few important precautions to consider. Do not take this medication if you are allergic to lansoprazole or other proton pump inhibitors. If you are pregnant, breastfeeding, or taking other medications, consult your doctor before use. Long-term use can affect nutrient absorption, so speak with your healthcare provider if you require prolonged treatment. If your symptoms persist or worsen after two weeks, seek medical advice.

FAQs

Please read our FAQs page to find out more.

Is lansoprazole a good option if I take clopidogrel?

Lansoprazole is generally one of the preferred acid-reducing medicines for people taking clopidogrel, as it is less likely than some others to interfere with how clopidogrel works. Even so, always tell our pharmacy team at info@rightangled.com about all your medicines so the right choice can be confirmed for you.

What if I struggle to swallow the capsule?

Some lansoprazole formulations can be opened and the granules taken in a little soft food or juice, or there are orodispersible versions that melt on the tongue. The granules should not be chewed. Check which formulation you have, or ask our pharmacy team for guidance.

Can it affect magnesium levels or bones with long use?

Prolonged use of this type of medicine has been linked to low magnesium levels and a small increase in fracture risk. These matter mainly with extended use, which is why long courses should be reviewed rather than continued indefinitely without assessment.

Does it interact with HIV medicines?

Lansoprazole can reduce the absorption of some HIV medicines, such as atazanavir, by lowering stomach acid. If you take any antiviral medicines, tell our pharmacy team at info@rightangled.com before starting.
