Driven by clinical results, MYOBLOC may help you achieve your treatment goals.

MYOBLOC is the first botulinum toxin therapy approved by the FDA for the treatment of CD and has proven efficacy backed by 11 clinical studies.

In multiple clinical studies, MYOBLOC injections have demonstrated an improvement in abnormal head position and neck pain associated with CD.

HOW DOES MYOBLOC WORK?

MYOBLOC disables a protein that would typically trigger the release of excessive acetylcholine, which causes muscles to become tense and spasm.

When your healthcare provider injects MYOBLOC into affected muscles, it blocks the release of acetylcholine, allowing them to relax.

Over time, your healthcare provider will adjust the dose of MYOBLOC to achieve maximum pain relief and muscle spasm control.

PATIENTS WHO RESPOND TO MYOBLOC CAN:

EXPERIENCE PAIN RELIEF AS EARLY AS 2 WEEKS AFTER INJECTION

NOTICE IMPROVEMENTS TO THEIR HEAD AND NECK POSITION (4 WEEKS)

FEEL RELIEF FOR 12-16 WEEKS

MYOBLOC achieved FDA approval based on 4 clinical studies that evaluated the efficacy, safety, and tolerability of MYOBLOC in both toxin A-responsive and toxin A-resistant adults with cervical dystonia. These studies assessed the ability of MYOBLOC to reduce the severity of abnormal head position, the effects of abnormal head position and pain on activities, and the severity and duration of dystonia pain.

IMPORTANT SAFETY INFORMATION

What is the most important information I should know about MYOBLOC?

MYOBLOC may cause serious side effects that can be life threatening. Call your doctor or get medical help right away if you have any of these problems after treatment with MYOBLOC:

Problems swallowing, speaking, or breathing. These problems can happen hours to weeks after an injection of MYOBLOC if the muscles that you use to breathe and swallow become weak after the injection and death can happen if you have severe problems.
- People with breathing problems who use muscles in their neck to help them breathe may be at greater risk.
- Swallowing problems may last several months and require a feeding tube. If severe, food or liquids may go into your lungs. People who already have swallowing or breathing problems are at highest risk.
Spread of toxin effects. In some cases, botulinum toxin may affect areas of the body away from the injection site and cause symptoms of botulism which include: loss of strength and muscle weakness all over the body; trouble saying words clearly (dysarthria); double vision; loss of bladder control; blurred vision and drooping eyelids; trouble breathing; hoarseness or change or loss of voice (dysphonia); trouble swallowing (dysphagia).

These symptoms can happen hours to weeks after you receive an injection of MYOBLOC.

These problems could make it unsafe for you to drive a car or do other dangerous activities.

Do not receive MYOBLOC if you:

are allergic to MYOBLOC or any of the ingredients in MYOBLOC.
had an allergic reaction to any other botulinum toxin product such as BOTOX®, BOTOX® Cosmetic (onabotulinumtoxinA), DYSPORT® (abobotulinumtoxinA), or XEOMIN® (incobotulinumtoxinA).
