Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- See a doctor before using it if you have trouble swallowing, unexplained weight loss, vomit blood, black stools, or are over 55 with new or changed indigestion. These can be signs of something more serious.
- Long-term use can lower magnesium and vitamin B12 levels and may slightly raise the risk of bone fractures. Your doctor will review whether you still need it.
- It can affect how some medicines work, such as clopidogrel (especially with omeprazole and esomeprazole), methotrexate, some HIV medicines and some antifungals.
- Tell your doctor if you have liver problems or are due to have a stomach test (endoscopy or breath test).

Like all medicines, Prevacid can cause side effects, but not everybody gets them.
Common side effects
- Headache
- Diarrhoea or constipation

- Muscle cramps, shaking, an uneven heartbeat or fits (possible low magnesium, with long use)
- A rash on sun-exposed skin with joint pain (a rare lupus-like reaction)

- Swallow the capsule whole with water, or let the orally dispersible tablet melt on your tongue.
- A common adult dose is 15 mg to 30 mg once a day.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
