Preventative (prophylactic) medicines

Your doctor may decide to prescribe you some preventive medicines if acute therapy fails to control your symptoms, or if you experience several attacks per month (more than three or four). It is important to take the medicine every day as directed by your doctor, even if you feel well. Your doctor may tell you to stop taking the medicine, for example every six months, to check that you still need to take it.

There are a number of possible medicines that your doctor may decide to treat you with, depending on the severity and associated symptoms that you experience. If one medicine does not work or causes side effects, another medicine may be more suitable.
