What is Losec?

Losec is the brand name for omeprazole, which is a prescription medication used to treat gastroesophageal reflux disease (GERD) and acid reflux.

Losec contains the active ingredient omeprazole, which inhibits the activity of the proteins known as proton pumps; these pumps produce stomach acid. It is part of a group of medicines that are called proton pump inhibitors (PPIs).

You can buy Losec either in the form of capsules or as a multiple unit pellet system (Losec MUPS).

The 20mg (28 capsules) dosage is available for next day delivery at Medicine Direct's online pharmacy.

What is Losec used for?

Losec is an effective treatment for anyone suffering from acid reflux, providing a cure for anyone with excessive stomach acid. Excess acid in the stomach can be painful and lead to stomach ulcers or the erosion in the lining of your throat.

As well as treating acid reflux, taking Losec can be used to treat gastrointestinal ulcers and heartburn.

Who can take Losec?

Losec and other omeprazole products are not suitable for everyone. If you have any concerns or doubts, you should contact your pharmacy or speak to your doctor before you take either Losec MUPS or tablets.

If you are pregnant, trying to get pregnant or are breastfeeding, it is not recommended that you take Losec.

Losec can interact with several different medicines, please refer to our Warnings and Drug Interactions tab for the full list of medicines that can have an adverse effect when taken with Losec.

Possible side effects

As is the case with all medicines, omeprazole medicines do have the risk of certain side effects.

Losec is considered a safe drug to take and most people who use it will not experience any adverse effects from the medicine. For those who do experience an adverse effect, they are usually mild and will not last for very long.

Common side effects when using Losec include:

  • Stomach pain
  • Constipation
  • Headaches
  • Wind
  • Feeling sick
  • Being sick
  • Diarrhoea
  • Dizziness
  • Sleepiness
  • Difficulty in falling asleep

You may also develop an itchy or lumpy rash on your skin. Losec may cause swelling in your feet or ankles.

If these symptoms persist, you should speak to your doctor or pharmacist.

Please refer to our Side Effects tab for the full list of more serious reactions you may experience while taking Losec. If any of these symptoms appear, you are advised to contact 999 or go to A&E immediately, especially if you display symptoms of a severe allergic reaction.

Losec Dosage

Unless instructed differently by your doctor, you should take omeprazole medication once a day, preferably in the morning. Always read the patient information leaflet before taking any medicine.

For adults:

Take one dose of 20mg each day. This may vary from between 10mg and 40mg each day, depending on the severity of the condition you are being treated for.

For children:

Children with reflux oesophagitis, and who weigh 10-20kg, will usually be prescribed 10mg once a day.

For children who weigh more than 20kg, the recommended dose is 20mg.

Losec (omeprazole) capsules should be swallowed whole and taken with a glass of water.

If you have trouble swallowing capsules whole, you can open the capsule up over an empty glass and suspend it in a slightly acidic drink, such as fruit juice or yogurt, and take within 30 minutes.

Do not chew or crush the capsules as this will render the medicine ineffective.

Most people will experience the benefit of this medicine within the first hour after taking it, but it should be noted that in some cases it can take up to four days for the full effects to take hold. If your symptoms have not been alleviated by this time, we advise you to go back to your doctor for advice.

Losec can be taken with or without food, but try to take it at the same time each day. If you forget to take a dose, take it as soon as you remember, then go back to taking it at your regular time the next day.

Do not take two doses in the same day.
