Patient Reviews: How Omeprazole Has Made a Difference

What is Omeprazole?

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 brand names, including Losec and Prilosec.

By inhibiting proton pumps in stomach-lining cells, omeprazole prevents excessive acid secretion, thus treating conditions such as:

  • Heartburn
  • Acid reflux
  • Indigestion
  • Stomach ulcers
  • Gastro-oesophageal reflux disease (GORD)
  • Zollinger-Ellison syndrome

Understanding Heartburn?

Heartburn is a primary symptom of acid reflux and GORD. It occurs when stomach acid flows back into the oesophagus, resulting in a burning sensation in the chest. The backflow of acid has easy passage if the lower oesophageal sphincter is weakened, which means it easily relaxes and opens up.

Acid reflux can be quite painful and uncomfortable. If left untreated, frequently recurring acid reflux may cause severe damage to the oesophageal tissue.

Symptoms of heartburn include:

  • Burning pain in the chest
  • Pain at the back of the throat
  • Recurrent coughing or hiccups
  • Sour taste in the mouth

While acid reflux itself is not a serious condition, stomach acid can damage the cells in the oesophagus, which carries risks of further complications, such as Barrett's oesophagus. Speak to your doctor if you are concerned about developing Barrett's oesophagus as a result of chronic GORD.

There are steps you can take to prevent heartburn from developing, such as:

  • Avoid foods that might trigger heartburn or indigestion.
  • Avoiding lying down straight after a meal
  • Eating your food slowly
  • Reduce the amount of food you eat before bed

Other possible causes of heartburn include:

  • Anti-inflammatory medicines (such as Ibuprofen)
  • Pregnancy
  • Smoking
  • Stress

If you suspect a medication you are taking is causing acid reflux, speak to your doctor or ask a pharmacist for advice. They may be able to prescribe or recommend a heartburn treatment for you, like Omeprazole.

How Does Omeprazole Work?

Omeprazole is a proton pump inhibitor (PPI) that blocks cells in the lining of the stomach, which reduces the amount of acid produced in the stomach.

By reducing the amount of acid produced by the stomach, Omeprazole reduces the chances of acid reflux occurring.

How Do I Take Omeprazole?

Your doctor will determine a suitable starting dose of Omeprazole for you and how frequently you should take it.

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 the gullet heals.

When Should I Take Omeprazole?

You should take Omeprazole in the morning, with or without food.

Omeprazole capsules should be swallowed whole with a glass of water.

The doctor may increase or lower the dosage depending on how you respond to the treatment.

What Should I Do If I Forget to Take Omeprazole?

If you forget to take Omeprazole when you should, take it as soon as you remember.

Do not take more Omeprazole to make up for a missed dose.

What Should I Do If I Take More Omeprazole Than I Should?

Speak to your doctor or pharmacist right away if you accidentally take more Omeprazole than prescribed.

Taking more Omeprazole than you should is unlikely to treat your condition any more effectively but may increase your risk of side effects.

If you are unsure how much Omeprazole you should take, ask your doctor or consult the patient information leaflet.

Omeprazole Side Effects and Cautions

Before taking Omeprazole, we encourage you to read the patient information leaflet (PIL) enclosed with your medicine.

The patient information leaflet contains important information about taking and storing Omeprazole, including a complete list of side effects, ingredients, and instructions on what to do if you experience an allergic reaction.

You can view the patient information leaflet for Omeprazole online.

Omeprazole Allergies

Do not take Omeprazole if you are allergic to any of the ingredients used to make Omeprazole or are allergic to any other medication belonging to the proton pump inhibitor (PPI) class, such as lansoprazole.

If you experience any signs of an allergic reaction, stop taking Omeprazole and speak to your doctor urgently. If you experience a severe reaction, go straight to your nearest A&E department immediately. Take the medicine and packaging with you so the doctors can assess what you took and how much you took.

Signs of an allergic reaction may include:

  • Swelling of the lips, face, tongue and throat
  • Difficulty breathing
  • Difficulty swallowing
  • Raised, lumpy rash (hives)

Who Should Not Take Omeprazole?

Omeprazole may affect the effectiveness of other medicines. Ensure that you speak to your doctor about any medication you are currently taking, including those bought over-the-counter, on prescription, and health or dietary supplements.

Omeprazole During Pregnancy and Breastfeeding

If you are pregnant, think you might be pregnant, or plan on becoming pregnant soon, speak to your doctor or a pharmacist for advice on whether the benefits of this medicine outweigh any potential risks posed to you or your unborn child.
