Warnings and precautions

Consult your doctor or pharmacist before starting to take Estomil:

• if you have reduced vitamin B12 reserves or risk factors for it and receive long-term treatment with lansoprazole. As all medications that reduce the amount of acid, Estomil may reduce the absorption of vitamin B12,
• 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 medication to Estomil for reducing 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.Remember to mention any other symptoms you may notice, such as joint pain.

When taking lansoprazole, it may cause inflammation in the kidneys. 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 must inform your doctor of these signs.

Inform your doctor if you have a severe liver disease. The 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 malignant disease.

In case of experiencing diarrhea during treatment withEstomil, contact your doctor immediately, asEstomilhas been associated with a slight increase in infectious diarrhea.

If your doctor has prescribedEstomilin addition to other medications for the treatment ofHelicobacter pyloriinfection (antibiotics) or together 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, 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).
