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

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

Your doctor may prescribe Duomate Flas for the following indications:

  • Treatment of duodenal and gastric ulcers
  • Treatment of esophageal inflammation (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

It is possible that your doctor has prescribed Duomate Flas for another indication or at a different dose than indicated in this package leaflet. Follow your doctor's instructions regarding the administration of the medication.

2. What you need to know before taking Duomate Flas

Do not take Duomate Flas:

  • If you are allergic to lansoprazole or any of the other components of this medication (listed in section 6).
  • If you are taking another medication whose active ingredient is atazanavir (used in the treatment of HIV).

Warnings and Precautions

When taking lansoprazole, kidney inflammation may occur. The signs and symptoms may include decreased urine volume 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.

Consult your doctor before starting to take Duomate Flas:

  • If you have ever had a skin reaction after treatment with a medication similar to Duomate Flas to reduce stomach acidity.
  • If you are scheduled to undergo a specific blood test (Chromogranin A).

If you experience 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 Duomate Flas. Remember to mention any other symptoms you may notice, such as joint pain.

Inform your doctor if you have a severe liver disease. It may be necessary for the doctor 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 cancer.

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

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

If you are taking proton pump inhibitors like Duomate Flas, especially for 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 are taking Duomate Flas for more than three months, it is possible that your blood magnesium levels may decrease. Low magnesium levels can cause fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you experience any of these symptoms, see your doctor immediately. Low magnesium levels can also cause a decrease in blood potassium and calcium levels. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.

If you have been taking Duomate Flas for a long time (more than 1 year), your doctor will likely perform regular check-ups. During visits to your doctor, you should inform them of any new or abnormal symptoms and circumstances.

Using Duomate Flas with Other Medications

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medications.

In particular, inform your doctor if you are using medications that contain any of the following active ingredients, as Duomate Flas may affect their mode of action:

  • ketoconazole, itraconazole, rifampicin (used to treat infections)
  • digoxin (used to treat heart problems)
  • theophylline (used to treat asthma)
  • tacrolimus (used to prevent transplant rejection)
  • fluvoxamine (used to treat depression and other psychiatric disorders)
  • antacids (used to treat heartburn or acid regurgitation)
  • sucralfate (used to heal ulcers)
