Losec is the branded version of Omeprazole. Omeprazole is medically equivalent to Losec but is available at a lower price.

 Gastro-oesophageal reflux disease (GORD) is a digestive condition that commonly occurs in one in five people. It can affect people of all ages, including children. It is most common in adults aged 40 and over and occurs more in men than in women. 

Acid reflux occurs when stomach acid leaks out of the stomach and into the gullet (oesophagus), which is a long tube that runs from the mouth to the stomach. Acid reflux is most commonly caused by weakening of the lower sphincter muscles of the gullet. 

The common symptoms of GORD (acid reflux) include:

  • Heartburn – a burning pain or discomfort below the breastbone, usually worse after meals,
  • or when bending down, or when lying down
  • An unpleasant taste in the mouth, caused by reflux of acid from the stomach
  • Pain and difficulty in swallowing (dysphagia)

Most people respond well to treatment with medication and some people may require a long-term course of medication to control the symptoms of acid reflux.

One tablet daily. Try to take omeprazole at the same time each day to avoid missing any doses. The usual dose is once a day in the morning.


  1. You can take your capsules with food or on an empty stomach. 

    • It is recommended that you take your capsules in the morning.

    • You can take your capsules with food or on an empty stomach.

    • Swallow your capsules whole with half a glass of water. Do not chew or crush the capsules.

      This is because the capsules contain coated pellets which stop the medicine from being broken down by the acid in your stomach. It is important not to damage the pellets. 

    If you or your child have trouble swallowing the capsules:

    • -  Open the capsules and swallow the contents directly with half a glass of water or put the

      contents into a glass of still (non-fizzy) water, any acidic fruit juice (e.g. apple, orange or

      pineapple) or apple sauce.

    • -  Always stir the mixture just before drinking it (the mixture will not be clear). Then drink

      the mixture straight away or within 30 minutes.

    • -  To make sure that you have drunk all of the medicine, rinse the glass very well with half a

      glass of water and drink it. The solid pieces contain the medicine - do not chew or crush them. 


      If you forget to take a dose, take it as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose. Do not take a double dose to make up for a forgotten dose. 

Losec is not likely to affect your ability to drive or use any tools or machines. Side effects such as dizziness and visual disturbances may occur (see section 4). If affected, you should not drive or operate machinery. 


  • Headache.

  • Effects on your stomach or gut: diarrhoea, stomach pain, constipation, wind (flatulence).

  • Feeling sick (nausea) or being sick (vomiting). 

    • If you are allergic (hypersensitive) to omeprazole or any of the other ingredients of Losec.

    • If you are allergic to medicines containing other proton pump inhibitors (eg pantoprazole,

      lansoprazole, rabeprazole, esomeprazole).

    • If you are taking a medicine containing nelfinavir (used for HIV infection)

      If you are not sure, talk to your doctor or pharmacist before taking Losec.

      Take special care with Losec

      Losec may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Losec or while you are taking it, talk to your doctor straight away:

      • You lose a lot of weight for no reason and have problems swallowing.

      • Y ou get stomach pain or indigestion.

      • You begin to vomit food or blood.

      • Y ou pass black stools (blood-stained faeces).

      • You experience severe or persistent diarrhoea, as omeprazole has been associated with a small

        increase in infectious diarrhoea.

      • Y ou have severe liver problems. 


        1. Tell your doctor or pharmacist if you are taking any of the following medicines:

          • Ketoconazole, itraconazole, posaconazole or voriconazole (used to treat infections caused by a


          • Digoxin (used to treat heart problems)

          • Diazepam (used to treat anxiety, relax muscles or in epilepsy)

          • Phenytoin (used in epilepsy). If you are taking phenytoin, your doctor will need to monitor you

            when you start or stop taking Losec

          • Medicines that are used to thin your blood, such as warfarin or other vitamin K blockers. Your

            doctor may need to monitor you when you start or stop taking Losec

          • Rifampicin (used to treat tuberculosis)

          • Atazanavir (used to treat HIV infection)

          • Tacrolimus (in cases of organ transplantation)

          • St John’s wort (Hypericum perforatum) (used to treat mild depression)

          • Cilostazol (used to treat intermittent claudication)

          • Saquinavir (used to treat HIV infection)

          • Clopidogrel (used to prevent blood clots (thrombi))

        • Erlotinib (used to treat cancer)

        • Methotrexate (a chemotherapy medicine used in high doses to treat cancer) – if you are taking a

          high dose of methotrexate, your doctor may temporarily stop your Losec treatment

          If your doctor has prescribed the antibiotics amoxicillin and clarithromycin as well as Losec to treat ulcers caused by Helicobacter pylori infection, it is very important that you tell your doctor about any other medicines you are taking.
