Warnings and precautions

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

• if you are scheduled to have a specific blood test (Cromogranina A),
• if you have ever had a skin reaction after treatment with a similar medicine to Estomil Flas to reduce stomach acid,
• if you suffer from a skin rash, especially in sun-exposed areas, 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, it may cause inflammation in the kidneys. 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 must inform your doctor of these signs.

Inform your doctor if you have a serious liver disease. Your doctor may need to adjust the dose.

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

If your doctor has prescribedEstomilFlas in addition to other medications for the treatment of Helicobacter pylori infection (antibiotics) or along with anti-inflammatory medications to treat pain or rheumatism, read the prospectuses of these medications carefully.

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