an autoinjector (self-injection device). Choose a site where the skin is thick
enough to take the full length of the needle (1/4 inch). Avoid injecting
Generic Imitrex into a muscle or a vein. Your doctor should instruct you on
how to use the autoinjector and how to dispose of the empty syringes. You should
also read the instruction pamphlet that comes with Generic Imitrex. You can take
a second injection if your headache returns.However, never take more than 2 Generic Imitrex injections within 24 hours, and be sure to wait 1 hour

dose of Generic Imitrex of up to 100 milligrams, if your doctor advises it. If the headache returns,
you may take additional doses of Generic Imitrex at intervals of at least 2 hours.

after you have had an Generic Imitrex Injection, you may take single Generic Imitrex
Tablets, at intervals of at least 2 hours, up to a maximum of 200 milligrams

5 or 20 milligrams of the drug. The usual Generic Imitrex dosage is a single
spray in one nostril. If the headache returns, you may repeat the Generic Imitrex
dose once after 2 hours. Do not take more than 40 milligrams a day.
