1. What Estomil Flas is and what it is used for

The active substance of Estomil Flas is lansoprazole, a proton pump inhibitor. Proton pump inhibitors reduce the amount of acid produced by the stomach.

Your doctor may prescribe you Estomil Flas for the following indications:

  • Treatment of duodenal and gastric ulcers
  • Treatment of inflammation of the esophagus (reflux esophagitis)
  • Prevention of reflux esophagitis
  • Treatment of heartburn and acid regurgitation
  • Treatment of infections caused by the bacteria Helicobacter pylori, in combination with antibiotics
  • Treatment or prevention of duodenal or gastric ulcers in patients who require continuous treatment with non-steroidal anti-inflammatory drugs (NSAIDs) (NSAID treatment is used for pain or inflammation)
  • Treatment of Zollinger-Ellison syndrome

Your doctor may have prescribed Estomil Flas for another indication or at a different dose than indicated in this leaflet. Follow your doctor's instructions regarding the administration of the medicine.

You should consult a doctor if you get worse or if you do not improve after 14 days.

2. What you need to know before you take Estomil Flas

Do not take Estomil Flas

  • if you are allergic to lansoprazole or any of the other ingredients of this medicine (listed in section 6)

Warnings and precautions

Consult your doctor or pharmacist before starting to take Estomil Flas:

  • if you have reduced body stores of vitamin B12 or risk factors for this and receive long-term treatment with lansoprazole. Like all medicines that reduce acid, Estomil Flas may reduce the absorption of vitamin B12,
  • if you are scheduled to have a specific blood test (Chromogranin A),
  • if you have ever had a skin reaction after treatment with a medicine similar to Estomil Flas to reduce stomach acidity,
  • if you suffer from a skin rash, especially in areas of the skin exposed to the sun, consult your doctor as soon as possible, as it may be necessary to interrupt treatment with Estomil Flas. Remember to mention any other symptoms you may notice, such as joint pain.

When taking lansoprazole, kidney inflammation may occur. The signs and symptoms may include decreased urine output or the presence of blood in the urine and/or hypersensitivity reactions such as fever, skin rash, and joint stiffness. You should inform your doctor of these signs.

Tell your doctor if you have severe liver disease. Your doctor may need to adjust the dose.

Your doctor may have performed or may perform a complementary test called endoscopy to diagnose your disease and/or rule out a malignant disease.

If you experience diarrhea during treatment with Estomil Flas, contact your doctor immediately, as Estomil Flas has been associated with a slight increase in infectious diarrhea.

If your doctor has prescribed Estomil Flas in addition to other medicines for the treatment of Helicobacter pyloriinfection (antibiotics) or together with anti-inflammatory medicines to treat pain or rheumatism, also read the patient information leaflets of these medicines carefully.

Taking a proton pump inhibitor like Estomil Flas, especially for a period of more than one year, may slightly increase the risk of hip, wrist, or vertebral fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which may increase the risk of osteoporosis).

If you have been taking Estomil Flas for a long time (more than 1 year), your doctor will probably have you checked regularly. During visits to your doctor, you should inform them of any new or abnormal symptoms or circumstances.

Other medicines and Estomil Flas

3. How to take Estomil Flas

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

Place the tablet on the tongue and suck it slowly. The tablet dissolves quickly in the mouth, releasing microgranules that should be swallowed without chewing. You can also swallow the tablet whole with a glass of water.

Your doctor may give you instructions to administer the tablet via a syringe, in case you have serious difficulties swallowing.

Follow the following instructions in case of administration via a syringe:

It is important that you check that the selected syringe is suitable.

  • Remove the plunger from the syringe (at least a 5 ml syringe for the 15 mg tablet and a 10 ml syringe for the 30 mg tablet).
  • Place the tablet in the reservoir.
  • Put the plunger back into the syringe.
  • For the 15 mg tablet: fill the syringe with 4 ml of water.
  • For the 30 mg tablet: fill the syringe with 10 ml of water.
  • Turn the syringe upside down and pull the plunger to allow 1 ml of air to enter.
  • Gently shake the syringe for 10-20 seconds until the tablet is dispersed.
  • The contents can be emptied directly into the mouth.
  • Refill the syringe with 2-5 ml of water to remove any remaining residue from the syringe and empty it into the mouth.

If you take Estomil Flas once a day, try to take it at the same time every day. You may get better results if you take Estomil Flas in the morning.

If you take Estomil Flas twice a day, you should take the first dose in the morning and the second dose at night.

The dose of Estomil Flas depends on your general condition. The usual doses of Estomil Flas for adults are indicated below. Sometimes, your doctor may prescribe a different dose and indicate a different duration of treatment.
