Details

What is Losec and what does it do?

Losec is a medicine that is used to reduce the amount of acid in the stomach. Losec can be used to treat heartburn and acid reflux, but can also be prescribed to treat GORD (gastro-oesophageal disease) and ulcers.

Stomach acid is produced by certain cells in the stomach called proton pumps. Losec works by inhibiting the amount of acid produced so that it is less likely to escape and irritate the gullet.

When is Losec prescribed?

Losec can be prescribed to treat ulcers and gastroesophageal reflux disease (GORD) in adults and children.

In adults, Losec can be prescribed to treat different types of ulcers, including ulcers in the upper part of the intestine, ulcers infected with bacteria and ulcers caused by medicines called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Examples of NSAIDs are ibuprofen, aspirin and diclofenac.

Is Losec suitable for my condition?

It depends on your medical history and whether you take any other medicines. Certain conditions and medicines may affect the suitability of Losec and cause side effects, or affect the efficiency of this drug.

It is important that you tell our doctors through the medical questionnaire if you take any other medication. This applies to prescription medicine and over the counter medication and supplements.

Losec may not be prescribed if any of the following applies to you:

  • If you are allergic to Losec, omeprazole or any of the ingredients listed in the patient information leaflet.
  • If you are allergic to Losec or any medicine containing other proton pump inhibitors, including pantoprazole, lansoprazole, rabeprazole and esomeprazole.
  • If you are taking a medicine containing nelfinavir (used for HIV infection)

What is the recommended dosage of Losec?

You should follow the doctor’s instructions on how to take this medicine. The doses outlined below is for your reference only. You are recommended to take the capsules in the morning, with or without food. Swallow the capsules whole with water.

Never exceed the stated dose.

Losec doses for adults:

To treat symptoms of heartburn and acid reflux:

If your gullet (food pipe) has been slightly damaged, take 20mg (1 capsule) once a day for 4 - 8 weeks. If your gullet has not healed at the end of the course, the doctor may instruct you to take a dose of 40mg per day for a further 8 weeks.

Once your gullet has healed, the recommended daily dose is 10mg.

If your gullet is not damaged, the recommended dose to treat heartburn and acid reflux is 10mg once a day.

To treat ulcers in the upper part of the intestine (called Duodenal Ulcer)

The recommended dose for treating a duodenal ulcer is 20mg once a day for 2 weeks. If your ulcer has not healed at the end of the course, the doctor may instruct you to take the same dose for a further 2 weeks. If your ulcer has not fully healed, the doctor may increase your dose to 40mg once a day for 4 weeks.

To treat ulcers in the stomach (called gastric ulcer):

The recommended dose for treating a gastric ulcer is 20mg once a day for 4 weeks. If your ulcer has not healed at the end of the course, the doctor may instruct you to take the same dose for a further 4 weeks. If your ulcer has not fully healed, the doctor may increase the dose to 40mg once a day for 8 weeks.

To prevent duodenal and stomach ulcers from coming back, the doctor may prescribe 10mg or 20mg to be taken once a day.

To treat duodenal and stomach ulcers caused by NSAIDs:

The doctor may prescribe 20mg to be taken once a day for 4 - 8 weeks.

To prevent duodenal and stomach ulcers from forming while taking NSAIDs, the doctor may prescribe 20mg to be taken once a day.

Losec may hide symptoms of other conditions and diseases. It is important that you contact your own GP immediately if you notice any of the symptoms below:

  • You experience unexplained weight loss or have problems swallowing.
  • You get stomach pain or uncomfortable indigestion.
  • You begin to vomit or vomit blood.
  • You pass black stools.
  • You experience severe and/or persistent diarrhoea.
  • You have severe liver problems.
  • You have even had a skin reaction after treatment with a medicine similar to Losec or omeprazole.

Does Losec cause any side effects?

All medicines can cause side effects, although not everyone gets them. Common side effects from taking Losec include:

  • Headache
  • Effects on your stomach, such as diarrhoea, stomach pain, constipation and flatulence.
  • Feeling sick or being sick (vomiting).

You should contact your GP or nearest clinic immediately if you experience any of the below side effects:

  • Sudden wheezing, swelling of your lips, tongue and throat or body, skin rash, fainting or difficulties swallowing. These symptoms may indicate that you are having a severe allergic reaction.
  • Reddening of the skin with blisters or peeling, severe blisters or bleeding in the lips, eyes, mouth, nose or genitals.
  • Yellow skin, dark urine and tiredness which may indicate liver problems.

Can I reduce the risk of getting side effects?

Yes. You should always read the patient information leaflet thoroughly before use as this can help reduce the risk of side effects and interactions between medicines. Below are a few things you can do:

  • While filling in the medical questionnaire, remember to include any other medicines you are taking. Omeprazole and Losec can affect how other medicines work, so it is important that you tell our doctors about all medicine you take. Don’t forget to also include over the counter medication and supplements.
  • Read through the patient information leaflet to find out whether to take the medicine with food or on empty stomach. Some medicines can cause stomach upset when taken on an empty stomach.
  • Reduce the amount of alcohol you drink, or exclude alcohol completely until your course has finished. Alcohol can increase the risk of side effects of most drugs.

How do I buy Losec online?
