You may only know BOTOX® as a wrinkle treatment, but botulinum toxin type A was used to treat medical problems, such as Blepharospasm (abnormal spasms of the eyelid), years before it was used for cosmetic purposes.

Blepharospasm causes spasms in and around the eyelids. This results in frequent blinking and closing of the eyes that you cannot control. Because of these symptoms, it can be hard to see. But with treatment, you may be able to manage your symptoms. Many people have turned to BOTOX® for relief with positive results.

What is BOTOX® botulinum toxin A?

It is a toxin produced by the bacteria Clostridium botulinum which temporarily blocks the action of muscles.

Is botulinum toxin A safe?

Botulinum toxin is an approved treatment for Blepharospasm, hemifacial spasm and facial wrinkles. Long-term follow-up studies have shown it to be a very safe and effective treatment with up to 90 percent of patients obtaining almost complete relief of their Blepharospasm.

How is botulinum toxin A used for therapeutic uses?

It is used to treat Blepharospasm. Blepharospasm refers to eyelid muscles around the eye that close involuntarily. This may cause loss of vision, especially while reading, headaches and eyebrow strain. The early symptoms of blepharospasm include increased blink rate, eyelid spasms, eye irritation, midfacial or lower facial spasm, blow spasm and eyelid tic. Injection of tiny doses of botulinum toxin at several sites above and below the eyes can significantly relieve these symptoms.

How long does it take to work?

Benefits begin in about a week after injection and last for an average of three to four months.
