Buy Losec Online

Losec is a prescription-only medicine which reduces the level of acid produced in the stomach, to bring relief from Gastro Oesophageal Reflux disease (GORD), a condition commonly referred to as heartburn. Losec is available in 10 mg, 20 mg, and 40 mg tablets.

You can safely buy Losec capsules online from our UK registered pharmacy. If your order is approved before 3pm, our dispensing pharmacy will process your order and dispatch it the same day via a next-day, discreet delivery.

What is Heartburn?

Heartburn is a condition characterised by a burning sensation around the chest. It is caused by acid reflux, when stomach acid finds its way up the oesophagus. This starts with the relaxation of the lower oesophageal sphincter, a muscular ring that connects the stomach and the oesophagus. Heartburn then becomes GORD after repeated episodes.

There are a number of potential triggers of heartburn, though it can be difficult to pin-point your triggers.

Some common triggers of heartburn include:

  • Acidic food (tomatoes)
  • Alcohol
  • Citrus (oranges, lemons)
  • Coffee
  • High fat food (cheese, nuts)
  • Onions and garlic
  • Pain relief medicines (ibuprofen, codeine, aspirin)
  • Spicy food

One method of determining a potential trigger of heartburn is to keep a food diary. Keep a record of the meals you eat, the time you ate them and any activities you did surrounding them. For example, whether you had a nap after a large meal or if you eat straight after exercising.

Next to each meal, take a note of whether you experienced heartburn, how long it lasted and a rating of the pain you experienced from 0 (indicating no pain) to 10 (unbearable pain). Do take your food diary with you to your doctors appointment as it can help them assess your condition and provide actionable steps on how to prevent or treat your symptoms.

It is important to treat chronic heartburn as it can result in serious oesophageal cell damage, causing a condition called Barrett's Oesophagus. In rare cases, Barrett's Oesophagus can develop into oesophageal cancer. According to Cancer Research UK, the risk of oesophageal cancer in patients with Barret's Oesophagus is greatly reduced by up to 71% by using proton pump inhibitors, such as Losec, to treat GORD and heartburn.

How does Losec work?

Losec contains a proton pump inhibitor known as omeprazole. It prevents cells in the stomach from producing an excess of stomach acid, which can increase the risk of developing heartburn and GORD symptoms. Losec's suppression of acid production is through H+/K+ ATPase enzyme inhibition at the stomach parietal cell secretory surface.

How do I take Losec?

You should always take Losec precisely as the pharmacist or doctor prescribes. If you are unsure about how you should take Losec, consult your doctor or pharmacist for assistance.

The doctor will determine an appropriate course of treatment for you, depending on your age and condition.
