~Botulinum Toxin Type B

I am writing to tell you about MYOBLOCTM (Botulinum Toxin Type B) Injectable Solution, a new botulinum toxin therapy. MYOBLOC has been shown to be effective in patients with cervical dystonia (also known as spasmodic torticollis) to reduce neck pain and allow for more normal head positioning.

In clinical studies, patients treated with MYOBLOC showed a greater reduction in neck
pain and in abnormal flead position versus those patients who had received inactive drug (placebo). In patients who responded, the effect of MYOBLOC typically lasted 3 to 4 months. The most frequent side effects reported with MYOBLOC are dry mouth, difficulty
swallowing, upset stomach, and pain at the injection site. These side effects are generally mild to moderate, temporary, clear up on their own, and more common with higher doses.

MYOBLOC is the only botulinum toxin therapy available in a ready-to-use solution that requires only refrigeration storage. It can be stored in your doctor’s refrigerator for up 21 months in unopened vials. In addition MYOBLOC is available in three convenient dosing volumes, which allows your doctor to customize therapy to your individual needs.

If you begin therapy with MYOBLOC, you will also discover another important benefit the Solutions Program~-a patient support program specially created for patients who are receiving treatment with MYOBLOC.
