Relpax - Dosage eletriptan hydrobromide
Dosage & Administration
The maximum recommended single dose is 40 mg.
In controlled clinical trials, single doses of 20 mg and 40 mg were effective for the acute treatment of migraine in adults. A greater proportion of patients had a response following a 40 mg dose than following a 20 mg dose [see Clinical Studies (14)].
If the migraine has not resolved by 2 hours after taking RELPAX, or returns after transient improvement, a second dose may be administered at least 2 hours after the first dose. The maximum daily dose should not exceed 80 mg.
The safety of treating an average of more than 3 migraine attacks in a 30-day period has not been established.
Dosage Form & Strengths
20 mg Tablets: Orange, round, convex shaped, film-coated, with "PFIZER" and "REP20" debossed.
40 mg Tablets: Orange, round, convex shaped, film-coated, with "PFIZER" and "REP40" debossed.
Tablets: 20 mg and 40 mg (3)
Overdosage
The elimination half-life of eletriptan is about 4 hours [see Clinical Pharmacology (12.3)], therefore monitoring of patients after overdose with eletriptan should continue for at least 20 hours or longer while symptoms or signs persist.
There is no specific antidote to eletriptan.
It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentration of eletriptan.
