Omeprazole is used to treat and prevent some stomach and gut problems, such as indigestion, reflux, and ulcers. It reduces the amount of acid made in your stomach.
Take omeprazole regularly as directed with a glass of water. You can take it with or without food, but it may work better if you take it before food.
Capsules or tablets: If you have trouble swallowing you can open the capsule or break the tablet and mix with a small amount of soft food or liquid. Swallow without chewing. Do not crush the capsule contents or tablets.
Liquid: Shake well before use. Measure each dose carefully with an oral syringe or measuring spoon.
If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.
Some medicines available without a prescription may react with omeprazole including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
|Side Effects||Recommended action|
Muscle twitching or cramps, tiredness or weakness, tingling or numbness (may be signs of low magnesium)
|Tell your doctor|
|Tell your health professional if troublesome|
If you notice any other effects, discuss them with your doctor or pharmacist.
