Warnings and precautions
Tell your doctor if you have a severe liver disease. It may be that the doctor needs 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.
In case you experience diarrhea during treatment with Opiren, contact your doctor immediately, as Opiren has been associated with a slight increase in infectious diarrhea.
If your doctor has prescribed Opiren in addition to other medicines intended for the treatment of Helicobacter pyloriinfection (antibiotics) or together with anti-inflammatory drugs to treat pain or rheumatism, also read carefully the package leaflets of these medicines.
Taking a proton pump inhibitor like Opiren, 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 (reduced bone density) or if your doctor has told you that you are at risk of osteoporosis (for example, if you are taking steroids).
If you have been taking Opiren for a long time (more than 1 year), your doctor will probably perform regular check-ups. During your doctor's visits, you should inform him of any new or abnormal symptoms or circumstances.
Consult your doctor before starting to take lansoprazole:
Taking Opiren with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription.
In particular, inform your doctor or pharmacist if you are taking medicines that contain any of the following active substances, as Opiren may affect their mode of action:
Taking Opiren with food and drinks
To get the best results from your medicine, you should take Opiren at least 30 minutes before meals with a glass of water.

If you are pregnant, or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Patients taking Opiren may occasionally experience side effects such as dizziness, drowsiness, fatigue, and visual disturbances. If you experience any of these side effects, you should act with caution as your reaction ability may be reduced.
