The Best way to treat Migraines with Botox
Having published both in Science(296:5567;468-469:2002) and The New England Journal of Medicine (345:764-76:2002) on Botox and Migraines the recent
literature suggests the following:
1. a dose of 155 units.
2, a dilution of 100U /2cc to prevent diffusion to unwanted areas.
3. use a 30-32 gauge ½ inch needle.
4. the dose should be divided across 7 specific injection sites in the head and neck.
on each side except the procerus which gets a single injection.
5. Make Sure your physician understands this
6. My patients are reinjected every 3-12 months
Botox for Migraine headaches
Although some patients have reported that Botox injections have helped alleviate migraine headaches for up to 6 months, most patients will require repeat injections in 3 to4 months to prevent migraine recurrence.
BOTOX® for migraine often needs to be repeated in about 3 months
BOTOX® for migraine often needs to be repeated in about 3 months; and you may need a higher dose than 100 units [most of my patients need around 150 units, some need as much as 300 units, and some get by on 60-90 units].
After several treatment sessions you and your doctor will have a good idea of what is the ideal dose for you. As with other medications, your needs may change as time goes on, and the dose can be adjusted up or down to take this into account.

Botox lasts 3-4 months
Botox lasts in the body for about 3-4 months and slowly drops off over that timeframe. I'm not sure what kind of "reaction" you had to Botox but that's the lifetime of the product so you should be seeing it wear off soon. Your migraines will be getting worse now, simply because the Botox is wearing off and the muscles can contract again and cause the migraines!
