IMITREX DOSAGE
How should you take Imitrex?
Imitrex should be taken as soon as your symptoms appear,
but may be used at any time during an attack.
Imitrex is available in three forms: injection,
tablets, and nasal spray.
Imitrex injection
Imitrex injection is administered just below the skin
with 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 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 the medication. You can take a second injection if your headache
returns.However, never take more than 2 Imitrex injections within
24 hours, and be sure to wait 1 hour between doses of.
Imitrex tablets
Imitrex tablets should be swallowed whole, with liquid. If you
have had no relief 2 hours after taking Imitrex Tablets, you
may take a second dose of up to 100 milligrams, if your doctor
advises it. If the headache returns, you may take additional doses
of Imitrex at intervals of at least 2 hours. You should not take
more than 300 milligrams in one day. If your headache returns after you
have had an Imitrex Injection, you may take single Imitrex
Tablets, at intervals of at least 2 hours, up to a maximum of
200 milligrams in a day.
Imitrex nasal spray
Imitrex nasal spray is packaged in single-dose bottles
containing either 5 or 20 milligrams of the drug. The usual Imitrex
dosage is a single spray in one nostril. If the headache returns,
you may repeat the Imitrex dose once after 2 hours. Do
not take more than 40 milligrams a day.
Imitrex dosage for adults:
- Imitrex injection: The maximum single recommended Imitrex dose for an adult is 6 milligrams injected under the skin. The maximum recommended Imitrex dose that may be given within 24 hours is two 6 milligram injections taken at least 1 hour apart.
- Imitrex tablet: The usual Imitrex
dose for an adult is 25, 50 or 100 milligram tablet
taken with water or other liquid. The most you should take at one time
is 100 milligrams, and the most you should take in 1 day is 200 milligrams.
Imitrex doses should be spaced at least 2 hours apart.
If you have liver disease, you should not take more than 50 milligrams
of Imitrex Tablets at one time.
- Imitrex nasal spray: The recommended adult dose
ranges from 5 to 20 milligrams taken when the attack begins and repeated
once, if necessary, 2 hours later. Imitrex nasal spray doses
are usually taken as a single spray in one nostril, but if a 10 milligram
dose works best for you, you can take it as a 5 milligram spray
in each nostril. Do not use more than 20 milligrams at a time, or take
more than 40 milligrams a day.

have serious consequences. If you suspect an Imitrex
