Sibelium is used for the prevention of migraine headaches with or without aura (warning signs that occur before the headache begins). Sibelium should not be used for treatment of acute migraine headaches (headaches that have already started).
Sibelium helps to reduce the frequency of migraine attacks and, to a lesser extent, the severity of the attacks. Sibelium does not appear to have an effect on how long attacks last. The effect of Sibelium may not be seen for several weeks. Do not stop taking the medication due to lack of effect within the first six to eight weeks.
