3. How to take Omeprazol Stadapharm

Follow the instructions for administration of this medicine indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

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 medicine

• 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 medicine 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 substance and have an enteric coating that protects them and prevents them from breaking when passing through the stomach. The granules release the active substance in the intestine, where it is absorbed by the body to produce an effect.

What to do if you have problems swallowing the capsules

• If you have problems 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 medicine, fill the glass with water to about half, rinse it well, and drink the water. The solid parts contain the medicine; do not chew or crush them.

If you take more Omeprazol Stadapharm than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medicine and the amount ingested.

If you forget to take Omeprazol Stadapharm

If you forget 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.
