Botox® Frequently Asked Questions:

How long can I be treated with Botox?
Each treatment typically lasts up to 3 months and can be repeated as long as your condition responds to BOTOX® and you do not have any serious allergic reactions or other significant side effects. BOTOX® has been used for more than 15 years to help patients worldwide, and although formal, long-term clinical evaluations have not been conducted, its safety in long-term use has been well established.
Although most people continue to respond to BOTOX® injections, some people have experienced a diminished response over time. There may be several explanations for this:
1. Changes in your condition - If the pattern of your muscle activity changes, your healthcare provider may need to inject new muscles and/or change your dose. Identifying and injecting the affected muscle can be difficult, complicated by the changing pattern of muscle involvement and progression of the disorder.
2. Setting appropriate expectations - You may believe your first BOTOX® injection was more helpful than subsequent injections. That's because your condition was perhaps quite severe when you had your first injection. Subsequent injections are usually given before your condition becomes that severe again. Therefore, the relief you experienced with subsequent injections may not have been as dramatic as the first time.
3. Antibody formation - When foreign proteins, like botulinum toxins, enter your body, antibodies may form. If antibodies to botulinum toxin develop, you may no longer respond to treatment.

Because botulinum toxins are usually used to treat chronic conditions, it's important to preserve responsiveness to therapy.

How can I help maintain my response to Botox?

While the critical factors for neutralizing antibody formation have not been well characterized, you may be able to help maintain your response to BOTOX® by minimizing your total exposure. The potential for antibody formation may be minimized by injecting with the lowest effective dose given at the longest feasible intervals between injections.

How is Botox given?

BOTOX® is injected into the affected muscle(s). Your doctor will determine which muscles need to be treated.

Does the injection hurt?

Some people report discomfort from the injection. BOTOX® is reconstituted with sterile, preservative-free, normal saline for injection. The neutral pH of the injected solution, in combination with the fine-gauge needle your doctor will use, can help to minimize any injection-related pain.

When will Botox start to work?

If you're receiving BOTOX® for cervical dystonia, you'll usually see the effects within 2 weeks of the injection. If you're receiving BOTOX® for blepharospasm, you'll usually see effects within 3 days.

How long will the effect last?

BOTOX® offers sustained relief, dose after dose. The relief you'll feel from 1 treatment of BOTOX® will normally last for up to 3 months. Treatments can be continued as long as your condition responds to BOTOX®, and you do not have any serious allergic reactions or other significant side effects. When the relief begins to fade, you'll return to your doctor for your next treatment.

Usually, BOTOX® treatment is required approximately 4 times per year. Because symptoms can change over time, the amount and duration of relief you'll experience can vary. Consult your doctor, who can determine how to achieve the best possible results with BOTOX®.

What side effects have been seen with Botox?

The most frequently reported adverse reactions in patients receiving BOTOX® for the treatment of cervical dystonia are dysphagia (difficulty swallowing, 19%), upper respiratory infection (such as a cold or flu,12%), neck pain (11%), and headache (11%). Dysphagia is a commonly reported adverse event following treatment of cervical dystonia patients. In these patients, there are reports of rare cases of dysphagia serious enough to require the insertion of a gastric feeding tube (a tube for introducing nutritious, high-calorie fluids into the stomach).

The most frequently reported treatment-related adverse reactions in patients receiving BOTOX® for the treatment of blepharospasm are ptosis (droopy eyelids, 21%), superficial punctuate keratitis (inflammation of the cornea characterized by small erosions of the tissue covering the cornea, 6%), and eye dryness (6%). Reduced blinking from BOTOX® injection of the orbicularis muscle can lead to corneal exposure, persistent epithelial defect (a defect in the corneal covering), and corneal ulceration (a hollowed-out cavity in the cornea), especially in patients with VII nerve disorders.

Please seek immediate medical attention if swallowing, speech, or respiratory (breathing) disorders arise.

Is Botox right for me?

Your healthcare provider can help you decide if BOTOX® is right for you. In order to make the right treatment decision, you should discuss the following with your healthcare provider before choosing treatment:
• Clinical experience with the drug
• Effectiveness and side effects

Make sure your healthcare provider knows if you are pregnant, nursing, or taking any medications before receiving BOTOX® injections. Additionally, you should not receive BOTOX® if you have an infection at the injection site.

BOTOX® should be used with caution if you have other neurological diseases or disorders, or if you are taking aminoglycoside antibiotics or other drugs that interfere with neuromuscular transmission. Be sure to tell your healthcare provider about any prescription or over-the-counter medications you are taking before receiving BOTOX®.
