Side-effects
A medicine is only made available to the public if the clinical trials have shown that the benefits of taking the medicine outweigh the risks.
Once a medicine has been licensed, information on the medicine's effects, both intended and unintended, is continuously recorded and updated.
Some side-effects may be serious while others may only be a mild inconvenience.
Everyone's reaction to a medicine is different. It is difficult to predict which side-effects you will have from taking a particular medicine, or whether you will have any side-effects at all. The important thing is to tell your prescriber or pharmacist if you are having problems with your medicine.
