By reducing acid levels, it helps prevent irritation of the stomach and esophagus, providing long-lasting relief from symptoms like heartburn, difficulty swallowing, and persistent cough caused by acid reflux.

Medication details

Description

Lansoprazole Tablets are designed to provide effective relief from acid-related conditions such as heartburn, acid reflux, and stomach ulcers. As a proton pump inhibitor (PPI), Lansoprazole works by reducing the amount of acid produced in the stomach, helping to ease discomfort and promote healing. Whether you experience frequent acid reflux or need treatment for a stomach ulcer, these tablets offer a trusted and clinically proven solution.

Always follow medical advice for safe and effective use. If you have any questions, don’t hesitate to ask your pharmacist or healthcare provider.

Directions

For best results, take Lansoprazole exactly as directed. It is usually taken once daily before a meal, preferably in the morning. Swallow the tablet whole with a glass of water, without crushing or chewing it. If you have difficulty swallowing, some brands allow you to open the capsule and mix the granules with a small amount of soft food or juice. Always follow the advice of your healthcare provider regarding dosage and duration of use.

Ingredients

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

Side Effects

Like all medications, Lansoprazole may cause 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. In rare cases, long-term use may lead to more serious issues such as low magnesium levels or increased risk of fractures. If you notice severe side effects like persistent stomach pain, unexplained weight loss, or difficulty swallowing, seek medical attention promptly.

Warnings

Before using Lansoprazole, it’s important to be aware of certain precautions. 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 may affect nutrient absorption, so speak to your healthcare provider if you need prolonged treatment. If your symptoms persist or worsen after two weeks of use, seek medical advice.

FAQs

Please read our FAQs page to find out more.

How long does it take for Lansoprazole to work?

Lansoprazole starts reducing stomach acid within a few hours, but it may take a few days to feel the full relief of symptoms. For conditions like acid reflux or ulcers, noticeable improvement usually occurs within a week.

Can I take Lansoprazole with other medications?

Some medications may interact with Lansoprazole, including certain antibiotics, blood thinners, and antifungal drugs. It’s always best to check with your doctor or pharmacist before taking it alongside other medicines.

What should I do if I miss a dose?

If you forget to take a dose, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed one and continue with your regular schedule. Do not take a double dose to make up for the missed one.

Can I stop taking Lansoprazole once I feel better?

Even if your symptoms improve, you should complete the course recommended by your doctor. Stopping too soon may cause symptoms to return. If you’re taking it long-term, consult your healthcare provider before discontinuing use.
