There are a number of different ways you can take omeprazole, depending on the condition is it being used to treat. If you are using over-the-counter omeprazole, here is what you need to know:

• Don't take over-the-counter omeprazole for longer than two weeks without first consulting your doctor.
• If you are taking 10mg omeprazole, then it is typical to take just one a day in the morning.
• If you are finding that over-the-counter omeprazole is ineffective, speak to your doctor, who may prescribe a stronger dosage.

Your doctor will decide on the safest dosage of omeprazole for you. However, the following guidelines have been taken from the NHS:

• For the treatment of indigestion, between 10mg-20mg a day is usually sufficient.
• For the treatment of heartburn and acid reflux, 20mg – 40mg is normally recommended.
• Further uses and doses can be found in the patient information leaf
