Buy Omeprazole Online

Omeprazole is a proton pump inhibitor or antacid. It is used for the treatment of several conditions of the stomach and oesophagus resulting from too much acid in the stomach. Omeprazole is typically used to treat frequent heartburn and gastro oesophageal reflux disease (GORD) and is available under a range of brands including Losec and Prilosec.

Omeprazole comes as 10 mg, 20 mg, and 40 mg capsules.

You can buy Omeprazole online from our UK regulated pharmacy. We understand the need for confidentiality when buying Omeprazole online, which is why our pharmacy packages all items in discreet, tamper-proof packaging which gives no indication of the contents or where it came from. Order before 3pm, Monday to Friday, and our UK pharmacy will dispense and dispatch your medicine the same day, for a fast next-day delivery.

What Is Heartburn?

Heartburn is a primary symptom of GORD. It occurs when stomach acid flows back into the oesophagus. The backflow of acid has easy passage when the lower oesophageal sphincter relaxes and opens up.

The burning sensation in the chest that accompanies heartburn is uncomfortable and can be quite painful. If left untreated, frequently recurring heartburn may cause severe damage to the oesophageal tissue.

How Does Omeprazole Work?

As a proton pump inhibitor, Omeprazole works by decreasing the amount of acid that the stomach produces. The drug inhibits the action of the cells in the lining of the stomach responsible for acid production.

By reducing the amount of acid produced by the stomach, Omeprazole prevents heartburn from occurring.

How Do I Take Omeprazole?

The amount and frequency, as prescribed by your doctor, will depend on your condition. Always follow the doctor's prescription when taking Omeprazole.

The recommended dose, unless prescribed otherwise by your doctor is as follows:

  • 10 mg once a day for 4-8 weeks if the gullet has not been damaged
  • 20 mg once a day for 4-8 weeks for a slightly damaged gullet. This dosage will be lowered to 10 mg a day after healing of the gullet.

To take, swallow one Omeprazole tablet in the morning with a glass of water. Omeprazole tablets can be taken with or without food.

The doctor may also increase or lower the dosage accordingly.
