Handling Side Effects

Use of Drugs

What to do if you experience a side effect


Side effects cannot be ruled out. If this happens, you should not hesitate to call or see your doctor or pharmacist immediately. Only he or she can advise you what to do, change your treatment, adjust the dose of your current treatment, or leave things as they are.


Your doctor is asked to report the side effect to the health authorities (e.g. the European Medicines Agency or the Food and Drug Administration in the USA) or to the manufacturer. The reports are then evaluated very carefully and the information might well end up in the patient leaflet which is continually updated to include any additional side effects that are observed in clinical practice over the years.


If you want to report a side effect or quality complaint, please contact your health care professional (e.g. treating physician or pharmacist), your local health authority, or contact us directly.
