1. What is Parizac and what is it used for
Parizac 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.
Parizac is used to treat the following conditions:
In adults:
- “Gastroesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the esophagus (the tube that 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 infected by a bacterium 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 NSAIDs (non-steroidal anti-inflammatory drugs). Parizac can be used to prevent ulcers if you are taking NSAIDs.
- Excess acid in the stomach caused by a tumor in the pancreas (Zollinger-Ellison syndrome).
In children:
Children over 1 year of age and = 10 kg
- “Gastroesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the esophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and heartburn.
In children, the symptoms of the disease can include return of stomach contents to the mouth (regurgitation), vomiting, and insufficient weight gain.
Children over 4 years of age and adolescents
- Ulcers infected by a bacterium 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.

| Frequent: | affect 1 to 10 patients in 100 | 
| Infrequent: | affect 1 to 10 patients in 1,000 | 
| Rare: | affect 1 to 10 patients in 10,000 | 
| Very rare: | affect less than 1 patient in 10,000 |

Other adverse effects are:

- Alterations in blood tests that check liver function.

Rare Adverse Effects
- Blood problems, such as decreased white blood cells or platelets. This can cause weakness or bruising and increase the risk of infection.
- Allergic reactions, sometimes very intense, including swelling of the lips, tongue, and throat, fever, and wheezing.
- Low sodium levels in the blood. This can cause weakness, vomiting, and cramps.
- Agitation, confusion, or depression.
- Taste alterations.
- Visual problems, such as blurred vision.
- Sudden feeling of difficult breathing (bronchospasm).
- Dry mouth.
- Inflammation of the mouth.

- Liver problems, such as jaundice, which can cause yellowing of the skin, dark urine, and fatigue.
- Hair loss (alopecia).
- Skin rash with exposure to sunlight.
- Joint pain (arthralgias) or muscle pain (myalgias).
- Severe kidney problems (interstitial nephritis).
- Increased sweating.
Very Rare Adverse Effects
- Blood count alterations, such as agranulocytosis (lack of white blood cells).
- Aggressiveness.
- Seeing, feeling, or hearing things that do not exist (hallucinations).
- Severe liver problems that cause liver failure and brain inflammation.
- Sudden appearance of an intense rash, blistering, or peeling of the skin. This can be accompanied by high fever and joint pain (erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis).

- Increased breast size in males.
Unknown Frequency
- Inflammation of the intestine (which causes diarrhea).
- Skin rash, possibly with joint pain.
- If you are taking Parizac for more than three months, it is possible that magnesium levels in your blood may decrease. Low magnesium levels can cause fatigue, muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you have any of these symptoms, consult your doctor immediately. Low magnesium levels can also produce a decrease in potassium and calcium levels in the blood. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.
- If you are taking proton pump inhibitors like Parizac, especially for a period of more than one year, you may slightly increase the 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).
In very rare cases, Parizac can affect the white blood cells in the blood and cause immunodeficiency. If you have an infection with symptoms such as fever with a very deteriorated general condition or fever with symptoms of local infection, such as neck, throat, or mouth pain, or difficulty urinating, you should consult your doctor as soon as possible to perform a blood test and rule out a lack of white blood cells (agranulocytosis). It is important that you provide information about the medication you are taking at that time.
