About Chronic Migrain

  • 15+ days

    15 or more days of experiencing headaches each month (also called headache days)
  • 4+ hours

    Each headache lasts for 4 or more hours each day

Understanding Botox®

BOTOX® is a treatment that can be used to prevent headaches in adults with chronic migraine, and in fact, it has been shown to significantly reduce the number of headache days per month in migraine sufferers.

How BOTOX® works

BOTOX® is a muscle relaxant that is injected into the muscles or deep into the skin. It works by partially blocking the nerve impulses to any muscles that have been injected and reduces excessive contractions of these muscles. The muscle relaxation is reversible with a time-limited duration of effect.

In the case of chronic migrain, it is thought that BOTOX® blocks pain signals, which indirectly block the development of migraine.


How Botox is Administrated®

BOTOX® is given via an intramuscular (into the muscles) injection. In the case of chronic migrain, BOTOX is injected into 7 specific head and neck muscle areas that may be contributing to the development of headaches.

Your doctor will determine the number of injection sites required to treat your specific condition.

BOTOX® injection sites for chronic migrain include the areas shown here:


The recommended dose of BOTOX® is 155 units in 31 sites, but if your doctor thinks it is necessary, he or she may decide to inject additional units of BOTOX

It is recommended that you receive your BOTOX® treatments 12 weeks apart.

There are several possible explanations for a lack of or diminished response to an individual treatment with BOTOX®. These include: the dose given may not have been adequate, the selected areas of injection may not have beed appropriate or the muscles selected for injection may not have been easily accessible.

Should you feel that you had a lack of or diminished response from treatment, be sure to talk to your doctor.

Preparing for treatment

Keep in mind that:
The treatment should take approximately 15 minutes.
The needle size is very small.
You can go hove as soon as your treatment is done.
