1. What Omeprazole SUN is and what it is used for

Omeprazole SUN contains the active substance omeprazole. It belongs to a group of medicines called ‘proton pump inhibitors’. These medicines work by reducing the amount of acid produced by the stomach.

Omeprazole SUN is used to treat the following conditions:

In adults:

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach escapes into the gullet (the tube which connects the throat to the stomach), causing pain, inflammation and heartburn.
  • Ulcers in the upper part of the intestine (duodenal ulcer) or in the stomach (gastric ulcer).
  • Ulcers caused by a bacteria called Helicobacter pylori. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
  • Ulcers caused by medicines called non-steroidal anti-inflammatory drugs (NSAIDs). Omeprazole SUN may also be used to prevent ulcers if you are taking NSAIDs.
  • Too much acid in the stomach caused by a tumour in the pancreas (Zollinger-Ellison syndrome).

In children:

Children over 1 year of age and ≥ 10 kg

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach escapes into the gullet (the tube which connects the throat to the stomach), causing pain, inflammation and heartburn.

In children, symptoms of the disease may include vomiting or regurgitation of food, and poor weight gain.

Children over 4 years of age and adolescents

  • Ulcers caused by a bacteria called Helicobacter pylori. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2. What you need to know before you take Omeprazole SUN

Do not take Omeprazole SUN

  • If you are allergic to omeprazole or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic to medicines containing proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
  • If you are taking a medicine that contains nelfinavir (used to treat HIV infection).

Do not take Omeprazole SUN if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Omeprazole SUN.

Warnings and precautions

Consult your doctor or pharmacist before taking Omeprazole SUN.

Serious skin reactions such as Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash with eosinophilia and systemic symptoms (DRESS) and acute generalized exanthematous pustulosis (AGEP) have been reported with omeprazole. Stop taking omeprazole and contact your doctor immediately if you experience any of these symptoms.

Kidney inflammation has been reported with omeprazole. Signs and symptoms may include decreased urine output or blood in the urine and/or hypersensitivity reactions such as fever, rash and joint pain. You should inform your doctor of these signs.

Omeprazole SUN may hide the symptoms of other diseases. Therefore, if you experience any of the following before you start taking Omeprazole SUN or during treatment, consult your doctor immediately:

  • Unintentional weight loss and difficulty swallowing.
  • Stomach pain or indigestion.
  • Vomiting food or blood.
  • Black stools (faeces stained with blood).
  • If you have severe or persistent diarrhoea, as omeprazole has been associated with a slight increase in infectious diarrhoea.

  • If you are due to have a specific blood test (Chromogranin A).

If you are taking proton pump inhibitors like Omeprazole SUN, especially over a period of more than one year, you may have a slightly increased risk of hip, wrist and spine fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which can increase the risk of osteoporosis).

If you get a rash on your skin, especially in areas exposed to the sun, you should contact your doctor as soon as possible, as you may need to stop your treatment with Omeprazole SUN. Also, remember to mention any other symptoms that you may notice, such as joint pain.

This medicine may affect how your body absorbs vitamin B12. If you have to take it for a long time, contact your doctor if you notice any of the following symptoms, which could indicate low levels of vitamin B12:

Adverse Effects of Unknown Frequency (frequency cannot be estimated from available data)
