Other Comments
There must be a drug-free interval of 3 to 4 weeks after every 6 month course of treatment.
If after a 3 week trial period, efficacy has not been demonstrated, continued administration is unlikely to be beneficial.
The protective effect of methysergide reportedly develops in 1 to 2 days and persists 1 to 2 days after the drug is discontinued.
Patients who take ergotamine for extended periods of time may become dependent on it and require progressively increasing doses for relief of vascular headaches and for prevention of dysphoria effects which follow withdrawal.
