SIDE EFFECTS: Common side effects include:
More serious side effects include:
PREPARATIONS: Tablets: 20 and 40 mg
STORAGE: Eletriptan should be stored at room temperature, 15 C - 30 C (59 F - 86 F), away from heat and light and out of the reach of children.
DOSING: Eletriptan 20 or 40 mg is taken at the first sign of a migraine attack. The maximum single dose is 40 mg. If the symptoms improve but then return after two hours or longer, a second tablet may be taken before calling the doctor. In any case, no more than 80 mg of eletriptan should be taken in any 24-hour period.
DRUG INTERACTIONS: Ergots, like dihydroergotamine (DHE 45) and ergotamine tartrate (Cafergot, Bellergal-S, Ergomar), or methysergide (Sansert) can causes constriction of blood vessels. It is possible that these effects may add to the effects of eletriptan. Therefore, it is recommended that ergot-containing drugs not be used within 24 hours of eletriptan.
Ketoconazole (Nizoral), itraconazole (Sporanox), nefazodone (Serzone), clarithromycin (Biaxin), ritonavir (Norvir), and nelfinavir (Viracept) may increase the amount of eletriptan in the blood by blocking an enzyme in the liver that's important in eliminating eletriptan. Eletriptan should not be taken if any of these medications have been taken within the previous 72 hours. Other drugs that block the same enzyme include diltiazem (Cardizem; Dilacor), Verapamil (Calan; Isoptin), fluconazole (Diflucan), voriconazole (VFend), indinavir (Crixivan), and erythromycin (Ery-Tab).
