Most side effects are minor and don't cause significant problems. However, a few are serious and need medical attention. Knowing what to do if you develop side effects can be confusing.
When prescribed a new medicine, ask your doctor or pharmacist what side effects to watch out for and what to do if you experience them. Ask them to write down their answers if you don't think you will remember them. Bear in mind that not everyone will experience the possible side effects, and some will be only temporary as your body gets used to the new medicine.
If you experience any change in how you feel while taking a medicine, make a note of the change. In particular, note what happens, when it happens, and how long it lasts.

Tell your doctor about any changes you have experienced when you next visit them—even if you don't know whether the change is a side effect. Your doctor needs to know about all the changes—positive and negative—so they have the information they need to decide whether the medicine is the most appropriate treatment for you.
If you think the change could be a serious side effect, contact a doctor without delay. If you are unsure what to do, ask a pharmacist for advice.
Even when side effects are not serious, they can be bothersome. If this is so, ask your doctor or pharmacist if there is any way of avoiding the side effects. There may be another way of taking the medicine or treating your condition.
Don't be tempted to take a smaller dose or to take the medicine less often in order to reduce the side effects. Doing so may make the medicine ineffective.
Read the medicine's Consumer Medicine Information (CMI) leaflet. CMI leaflets are available for most prescription medicines and some pharmacy medicines. The leaflet lists the medicine's side effects and tells you what to do if you experience them.
Ring Medicines Line and ask the pharmacist on duty any questions you may have about the medicine and its side effects. The service is free and confidential.
