Losec MUPS is a dispersible gastro-resistant tablet containing 20 mg of omeprazole used to treat conditions caused by excess stomach acid. MUPS stands for “Multiple Unit Pellet System” – a special formulation that allows the tablet to be dispersed in water, making it easier to swallow for those who have difficulty taking standard tablets.
Losec MUPS contains the active ingredient omeprazole, which belongs to a group of medicines called proton pump inhibitors (PPIs). These work by targeting the “proton pumps” in your stomach lining – the cells responsible for producing stomach acid.
When you take Losec MUPS, the omeprazole blocks these pumps, significantly reducing the amount of acid your stomach makes. This reduction in acid helps in several ways: it allows any damaged areas in your oesophagus or stomach to heal, prevents further damage from occurring, and relieves uncomfortable symptoms like heartburn and indigestion.
The dispersible formulation means the active ingredient is released in a controlled way, providing long-lasting acid suppression throughout the day. Most people notice their symptoms improving within a few days, though it may take up to four weeks to experience the full benefits.
Losec MUPS dispersible tablets are used to treat several conditions related to excess stomach acid:
Your doctor or pharmacist will determine which condition Losec MUPS is treating and advise you on the appropriate length of treatment.
Losec MUPS is suitable for adults who need treatment for acid-related conditions. The dispersible formulation makes it particularly useful for people who have difficulty swallowing standard tablets, including elderly patients.
However, Losec MUPS may not be suitable for everyone. You should consult your doctor or pharmacist before using Losec MUPS if you:
Before starting to take Losec MUPS, always let your doctor or pharmacist know about any medications you’re taking and any medical conditions you have. If you experience persistent stomach pain, unintentional weight loss, or difficulty swallowing, see your doctor before starting treatment, as these may be signs of a more serious condition.
Losec MUPS dispersible tablets offer flexible dosing options, making them easier to take than standard tablets.
If you prefer, you can swallow Losec MUPS tablets whole with a glass of water. Don’t chew or crush the capsules.
Like all medications, Losec MUPS can cause side effects, although not everyone experiences them. Most side effects are mild and improve as your body adjusts to the treatment.
If you experience any serious side effects, particularly if they’re severe or persistent, contact your doctor or pharmacist. If you notice signs of a serious allergic reaction (sudden wheezing, swelling of lips, tongue, or throat, or difficulty swallowing), stop taking Losec MUPS and seek immediate medical attention.
You can report side effects to the MHRA (Medicines and Healthcare products Regulatory Agency) via the Yellow Card Scheme to help monitor the safety of the medication.

MUPS contains omeprazole as its active ingredient. MUPS stands for “Multiple Unit Pellet System”, which is a special dispersible formulation of omeprazole. While both contain the same active ingredient and work in the same way, Losec MUPS has the advantage of being dispersible in water, making it easier to take for people who have difficulty swallowing standard omeprazole tablets.
Your doctor will tell you how long to take Losec MUPS. The duration depends on your condition – some people need short-term treatment for a few weeks, while others may need longer-term management. Don’t stop taking Losec MUPS without speaking to your doctor first, even if you feel better.
If you forget to take a dose, take it as soon as you remember on the same day. If you don’t remember until the next day, skip the missed dose and continue with your normal schedule. Don’t take a double dose to make up for a forgotten dose.
No, you shouldn’t cut, crush, or chew Losec MUPS tablets. The tablets contain special pellets designed to protect omeprazole from being broken down by stomach acid. If you cut or crush the tablet, it won’t work properly. If you have difficulty swallowing the tablet whole, use the dispersible method by placing it in water and drinking the mixture as directed.
Alcohol doesn’t interact directly with omeprazole, but it can irritate the stomach and worsen reflux. Limiting alcohol may help your symptoms.
