3. How to take Improzol

Follow the administration instructions for the medication contained in this prospectus or as indicated by your doctor or pharmacist exactly. In case of doubt, ask your doctor or pharmacist.

The recommended dose is one 20 mg capsule once a day for 14 days. Contact your doctor if symptoms do not disappear after this time.

You may need to take the capsules for 2-3 consecutive days to achieve an improvement in symptoms.

How to take this medication

• It is recommended to take the capsules in the morning.
• You can take your capsules with food or on an empty stomach.
• Swallow the capsules whole with half a glass of water. Do not chew or crush the capsules, as they contain coated granules that prevent the medication from breaking down due to the action of stomach acid. It is important not to damage the granules. These granules contain omeprazole as the active ingredient and have an enteric coating that protects them and prevents them from breaking when passing through the stomach. The granules release the active ingredient in the intestine, where it is absorbed by the body to obtain an effect.

What to do if you have trouble swallowing the capsules

• If you have trouble swallowing the capsules:
  • Open the capsules and swallow the contents directly with half a glass of water or pour the contents into a glass of still water, acidic fruit juice (e.g., apple, orange, or pineapple), or apple sauce.
  • Always shake the mixture just before drinking it (the mixture will not be transparent). Then, drink the mixture immediately or within 30 minutes.
  • To ensure that you have taken all the medication, fill the glass with water to the halfway point, rinse it well, and drink the water. Do not use milk or carbonated water. The solid parts contain the medication; do not chew or crush them.

Use in children and adolescents

Children and adolescents under 18 years of age should not take this medication.

If you take more Improzol than you should

If you have taken more omeprazole than recommended, consult your doctor or pharmacist immediately. You can also call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount taken.

If you forget to take Improzol

If you forgot to take a dose, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed dose. Do not take a double dose to make up for the missed doses.

In very rare cases, omeprazole may affect the white blood cells in the blood and cause immunodeficiency. If you have an infection with symptoms such as fever with a severely deteriorated general condition or fever with symptoms of local infection, such as sore throat, mouth, 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).
