What is Omeprazole and what is it used for?

Omeprazole is a widely used medication to treat indigestion, heartburn and acid reflux.

It belongs to a group of medications called ‘proton-pump inhibitors’ which works by reducing the amount of acid your stomach makes.

How and when do I take Omeprazole?

Adults should take one 20mg capsule with water, preferably first thing in the morning for four weeks. If you are prescribed to take Omeprazole twice a day, it is recommended to take 1 dose in the morning, and 1 dose in the evening.

It is important not to chew the capsule because it will not work properly otherwise.

Can I take Omeprazole?

Omeprazole can be taken by children and babies if it has been prescribed by the doctor. Adults including those that are pregnant and breastfeeding are able to take it.

Omeprazole contraindications – There are some instances where omeprazole is not suitable for people to take. You should tell your doctor if you:

  • Are deficient in vitamin B12
  • Are allergic to protein pump inhibitors
  • Have had liver disease before

What dosage should I take?

Omeprazole is a prescription medication coming in 3 different dosage levels: 10mg, 20mg and 40mg.

The dosage level will depend on what the doctor recommends for you and the severity of the condition. Therefore we advice you to consult with your GP to see which dosage is suitable for you.

How long should I take it for?

If you bought Omeprazole over the counter and have not seen any improvements in health within 2 weeks, it is best to consult with your doctor.

It is best to consult with your GP about what is best for you.

What if I forget to take it?

If you usually take it once a day: Take the missed dose as soon as you remember, unless it is within 12 hours of your next dose then skip the dose.

If you take it twice a day: Take the missed dose unless it is within 4 hours of your next dose.

What if I take too much?

If you accidentally exceed the recommended dosage by taking 1 or 2 extra doses, it is unlikely that it will cause problems.

Consult a doctor if you start suffering from any of these symptoms:

  • Flushed skin
  • Feel sweaty
  • Blurred vision
  • Feeling confused/agitated
  • Quicker heartbeat
  • Feel sleepy

Can I take Omeprazole with alcohol?

Yes. Alcohol does not interact with Omeprazole, but it can cause acid reflux. If you wish to drink alcohol, we would recommend you do so in moderation.

Can I take Omeprazole whilst I’m pregnant or breastfeeding?
