How to take omeprazole
Make sure you’re fully informed regarding omeprazole capsules by reading the leaflet that is enclosed within the package.
The dose is one capsule per day. It is best taken in the morning, without food, swallowed whole with half a glass of water. It should be swallowed whole and not chewed. However, if you have trouble swallowing them, the contents of the capsule can be taken out and swallowed with water, or mixed with water or fruit juice and taken immediately.
Depending on the severity of your symptoms, the doctor might recommend the 20mg or 40mg capsules.
When it’s being used to prevent stomach irritation in people who are also taking a non-steroidal anti-inflammatory drug (such as Arcoxia), then the usual dose is 20mg a day and omeprazole only needs to be taken for as long as you are also taking the non-steroidal anti-inflammatory drug (NSAID).
Is omeprazole suitable for me?
There are some situations where omeprazole, like all medicines, should be used with caution or would not be recommended at all – for example, in people who are allergic to any of its active or inactive ingredients. During your consultation with us, it is important that we’re informed if you are taking any other medicines – whether they’re prescribed by your doctor or bought from a pharmacy without a prescription. Omeprazole can cause problems if taken with certain other medicines, including some treatments for HIV/AIDS, and clopidogrel (Plavix).
You should use omeprazole with caution if you are pregnant or suspect you’re pregnant, or are breastfeeding or planning to breastfeed.
If this medication doesn’t work for you, tell the doctor because a different treatment might be better suited to you.
Please make sure you give the doctor a full picture of your general health in the consultation, to make sure we have all the information required to assess the suitability of omeprazole before recommending it for you.
What are the side effects of omeprazole?
Omeprazole is similar to any other medication in that it can cause side effects. However, not everybody will experience them.
If you noticed any of the following rare but serious side effects, stop taking Omeprazole Capsule and contact a doctor immediately:
- Sudden wheezing, swelling of your lips, tongue and throat or body, rash, fainting or difficulties in swallowing (severe allergic reaction).

You are most likely to experience headaches, abdominal pain, constipation, diarrhoea, flatulence, nausea and vomiting while taking omeprazole.
