    Losec MUPS is the branded version of Omeprazole. This particular brand comes in both the full strength and half strength of Omeprazole. It is a medicine that belongs to the family of drugs known as proton pump inhibitors (PPI). It is used to treat conditions such as acid reflux, gastro-oesophageal reflux disease (GORD) and heartburn. It works by preventing certain cells within the stomach lining from producing acid. This leads to a decrease in acid refluxing up towards the respiratory tract and causing symptoms associated with all the conditions above.  It is recommended that the patient take a daily dose regularly for therapeutic results to be at its most effective.

  • What Is the Difference Between Prescription and Over-the-Counter PPIs?

    Both prescription and over-the-counter PPIs contain the same active ingredients. They work in the same way, but OTC medications may contain a lower dose.

  • Are PPIs Safe?

    Long-term use can cause severe PPI side effects. Kidney disease, bacterial infections and bone fractures are some of the PPIs’ most serious side effects. You should only use this medication long term if advised by a healthcare professional.

  • How Do You Take a PPI?

    PPIs should be taken on an empty stomach, about 30 minutes to one hour before eating breakfast.

  • How Long Will I Have to Keep Taking PPIs?

    PPIs are generally supposed to be taken for two to eight weeks, depending on the condition being treated.

  • Can I drink alcohol?

    Drinking alcohol while taking PPIs can result in increased side effects and worsening of acid reflux.
