Works by

Esomeprazole works by blocking the acid-producing pumps in the stomach lining, effectively reducing the amount of acid produced. By lowering acid levels, it helps prevent irritation and inflammation, reducing symptoms such as heartburn, difficulty swallowing, and discomfort caused by acid reflux. It also plays a crucial role in healing stomach ulcers and preventing them from coming back. Many people use Esomeprazole for ongoing management of acid-related conditions, as it provides long-lasting relief and protection.

Side effects

Headache, nausea, stomach pain, diarrhoea, constipation, bloating, and benign stomach polyps​

Medication details

Description

Esomeprazole Tablets are specially formulated to provide relief from acid-related conditions such as heartburn, acid reflux, and stomach ulcers. As a proton pump inhibitor (PPI), this medication helps to reduce excess stomach acid, alleviating discomfort and preventing irritation in the stomach and esophagus. Whether you suffer from frequent acid reflux or need a treatment to help heal an ulcer, Esomeprazole offers a trusted and clinically proven solution.

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

Directions

For the best results, take Esomeprazole exactly as directed. It is typically taken once a day, preferably in the morning before eating. The tablet should be swallowed whole with a glass of water and should not be crushed or chewed. If you have difficulty swallowing tablets, some brands allow the tablet to be dissolved in water or opened and mixed with a small amount of soft food. Always follow your doctor’s or pharmacist’s advice regarding the correct dosage and duration of use to ensure the best outcome.

Ingredients

Each Esomeprazole tablet contains esomeprazole, the active ingredient that belongs to the proton pump inhibitor class of medications. Additional inactive ingredients may vary depending on the brand but typically include substances that help with tablet formulation and absorption. If you have allergies or specific dietary concerns, it’s best to check the ingredient list on the packaging or consult your pharmacist.

Side Effects

Like all medications, Esomeprazole may cause side effects, though not everyone experiences them. Some of the most common side effects include headaches, nausea, diarrhea, constipation, stomach pain, and bloating. Some individuals may also experience dizziness or dry mouth. Long-term use may lead to more serious effects, such as vitamin B12 deficiency, 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, you should seek medical attention immediately.

Warnings

Before taking Esomeprazole, it’s important to consider a few precautions. Do not take this medication if you are allergic to esomeprazole or other proton pump inhibitors. If you are pregnant, breastfeeding, or taking other medications, consult your doctor before use. Long-term use should only be done under medical supervision, as it may affect nutrient absorption over time. If your symptoms persist or worsen after two weeks of use, seek medical advice to ensure the correct treatment plan.

FAQs

Please read our FAQs page to find out more.

How is esomeprazole related to omeprazole?

Esomeprazole is the S-isomer of omeprazole, a closely related but distinct molecule from the same family of acid-reducing medicines. Because they are so similar, you should not take esomeprazole and omeprazole together, or alongside another medicine of the same type.

Can I disperse the tablet if I cannot swallow it whole?

Esomeprazole tablets can usually be placed in half a glass of still (non-fizzy) water and stirred until they disperse, then drunk straight away; rinse the glass with a little more water and drink that too. The granules should not be chewed or crushed. Check your product leaflet for the exact method.

Can I take esomeprazole if I am on clopidogrel?

Like omeprazole, esomeprazole can reduce how well clopidogrel works and this combination is best avoided; a different acid-reducing medicine is usually preferred for people on clopidogrel. Tell our pharmacy team at info@rightangled.com about all your medicines before starting.

Does esomeprazole interact with HIV medicines?

Esomeprazole is not recommended alongside atazanavir and may affect some other antiviral medicines, as lowering stomach acid changes how they are absorbed. If you take any HIV or antiviral medicines, tell our pharmacy team at info@rightangled.com before starting.
