Botox for Migraines FAQ

Frequently Asked Questions (FAQ) ~ BOTOX® and Chronic Migraine

What is BOTOX®

BOTOX® (onabotulinumtoxinA) is part of a group of drugs known as biologics—biologic medicines are made from living things. BOTOX® is a purified protein that is made from a type of bacteria calledClostridium botulinum type A.

BOTOX® is injected to prevent headaches in adults with Chronic Migraine who have 15 or more headache days each month with headache lasting 4 hours or more each day in people 18 years or older.

It is not known whether BOTOX® is safe or effective to prevent headaches in patients with migraine who have 14 or fewer headache days each month (episodic migraine).

Who makes BOTOX®?

BOTOX® therapy is made only by Allergan—a US-based specialty drug and medical device company offering innovative products in approximately 100 countries. Allergan is committed to significant and ongoing investment in research and development to pursue discoveries and treatments.

How can I be sure I am receiving authentic BOTOX®?

Allergan takes many steps to ensure that the distribution of BOTOX® (onabotulinumtoxinA) is safe and effective for patients.

Look for “Allergan” hologram

Only BOTOX® manufactured by Allergan is FDA approved and federally licensed to be sold and used in the United States. Products imported by foreign or unlicensed suppliers are not FDA approved and may be counterfeit.

There are a couple of easy ways to ensure you are receiving authentic BOTOX®:

  • The carton will have a US license number on the side
  • The vial will have the BOTOX®logo as well as a hologram (rainbow) image that says Allergan

How is BOTOX® treatment given to appropriate Chronic Migraine patients?

BOTOX® is injected by a doctor into 7 specific areas in the head and neck with very fine needles. A complete injection pattern has 31 total injections

What are the side effects with BOTOX®

The most common side effect seen in Chronic Migraine clinical trials was neck pain, experienced by approximately 9% of people in the BOTOX® group vs 3% in placebo group. Other side effects (experienced by ≥ 2% of people treated with BOTOX® and more frequent than placebo-treated patients) include headache, migraine, slight or partial facial paralysis, eyelid drooping, bronchitis, musculoskeletal stiffness, muscle weakness, pain in 1 or more muscles, ligaments, tendons, or bones, muscle spasms, injection-site pain, and high blood pressure. This does not cover all possible side effects of BOTOX®. Please see the Important Safety Information including Boxed Warning and Medication Guide and talk to your doctor.

What serious and/or immediate allergic reactions have been reported? 

These reactions include itching, rash, red itchy welts, wheezing, asthma symptoms, or dizziness or feeling faint. Tell your doctor or get medical help right away if you experience any such symptoms; further injection of BOTOX® should be discontinued.

How often will I need BOTOX® treatment? 

BOTOX® injections are given every 12 weeks by your doctor. Your doctor will decide if you need an ongoing therapy.

Can I still take acute medication for my migraines once I begin BOTOX® treatment? 

BOTOX® is a preventive medication for headaches in adults with Chronic Migraine. BOTOX® is a prescription medicine that is injected to prevent headaches in adults with Chronic Migraine (15 or more headache days a month with each headache lasting 4 hours or more). BOTOX® is not approved for adults with migraine who have 14 or fewer headache days a month.

BOTOX® may not prevent all your headache days. Acute medications may still be taken while you are on BOTOX therapy. Your doctor will recommend a complete treatment plan that’s right for you.

Chronic Migraine

What’s the difference between headaches and Chronic Migraine? 

Frequent or re-occurring migraines may often be referred to as chronic, or “chronic migraines.” However, Chronic Migraine is a medical condition that is defined by having headaches on 15 or more days per month, with each headache lasting 4 hours or more. If you have Chronic Migraine, at least 8 of your headache days are associated with migraine. Learn more about Chronic Migraine.
