Few cases of acute Sansert® (methysergide maleate) intoxication have been reported. The possible symptom complex is therefore not fully known. The following symptoms are based on these few case reports. Euphoria, hyperactivity, tachycardia, dilated pupils, and dizziness have been reported in a child with a dose of 20-24 mg of Sansert® (methysergide maleate). In adults, peripheral vasospasm, with diminished or absent pulses, coldness, mottling and cyanosis, has been observed at a dose of 200 mg. Ischemic tissue damage has not been reported in acute overdosage with Sansert® (methysergide maleate).

Treatment consists of removal of the offending drug by induction of emesis, or gastric lavage in the case of very recent intake, repeat dose administration of activated charcoal and catharsis. There is no evidence that forced diuresis accelerates the elimination of Sansert® (methysergide maleate). However, I.V. fluids may be given as a general supportive measure. Treatment of peripheral vasospasm should consist of warmth, but not heat, and protection of the ischemic limbs. In reported cases of Sansert® (methysergide maleate) overdosage, the use of vasodilators has not been necessary. However, if vasospasm is persistent, severe, or if there is evidence of impending ischemic tissue damage, these agents may be beneficial. Careful nursing care is recommended in order to prevent tissue damage.

Up-to-date information about the treatment of overdose can often be obtained from a certified Regional Poison Control Center. Telephone numbers of certified Regional Poison Control Centers are listed in the Physicians Desk Reference®.*
