What is Losec?

Losec is a branded form of omeprazole, a well‑known medicine from the proton pump inhibitor (PPI) family. It is used to treat acid reflux, heartburn, indigestion, and stomach or duodenal ulcers. Losec works by reducing the amount of acid your stomach produces, helping relieve symptoms and allowing the oesophagus and stomach lining to heal.

Like other PPIs, Losec:

  • Blocks the stomach’s acid‑producing pumps
  • Significantly reduces acid levels for up to 72 hours
  • Helps soothe inflammation and supports healing
  • Provides long‑lasting relief when taken daily

What is Losec used for?

Losec is commonly recommended for adults experiencing:

  • Acid reflux (GERD) – stomach acid travelling back into the food pipe, causing heartburn and irritation
  • Frequent or ongoing heartburn and indigestion
  • Stomach & duodenal ulcers – and to help prevent recurrence
  • Inflammation of the oesophagus caused by excess acid
  • Protection from acid‑related symptoms in people taking NSAIDs (e.g., ibuprofen)

What are the side effects of Losec?

Common Side Effects: 

These may affect up to 1 in 10 people:

  • Headache 
  • Diarrhoea,
  • Stomach pain
  • Constipation
  • Wind (flatulence) 
  • Feeling sick (nausea) or being sick (vomiting) 
  • Benign stomach polyps (harmless)

When to Seek Medical Help?

  • Severe allergic reaction (swelling, wheezing, rash, difficulty swallowing)
  • Severe skin blistering or peeling
  • Yellow skin or dark urine (possible liver problem)

Frequently asked questions

  • What is the best treatment for acid reflux?

    The most effective acid reflux treatment includes Omeprazole and Lansoprazole. These medications help reduce stomach acid, relieving heartburn and indigestion. A prescriber can recommend the most suitable option based on symptoms and medical history.

  • Can you buy omeprazole over the counter?

    Lower doses of Omeprazole are available without a prescription, but stronger doses require prescriber approval. This ensures the medication is safe and appropriate for individual needs, especially for those needing long-term management.

  • What to drink for acid reflux relief?

    Drinking water, herbal teas, and non-citrus drinks can help ease symptoms. Caffeinated drinks, alcohol, and fizzy beverages may worsen acid reflux and should be avoided where possible. Choosing the right fluids can support treatment and reduce irritation.

  • What not to take with Lansoprazole?


    Certain medications, including antacids, blood thinners, and some antibiotics, may interfere with treatment. A prescriber will check for any potential interactions before approving a prescription to ensure safe use.
