How Long Do Botulinum Toxin Injections Last?

The effect of one botulinum toxin injection usually lasts 3 to 4 months. Minimizing the use of treated muscles by controlling animation will help it last longer. The best time to retreat is when the underlying muscle has regained the partial ability to contract. If retreatment occurs before the muscles have fully regained their ability to move, the botulinum toxin injections are additive resulting in a longer lasting effect. This occurs because of muscle atrophy which usually occurs after 3-4 consecutive treatments.

What are the Side Effects?

Temporary bruising is possible and is minimized by avoiding aspirin-like products for 1 week, Vitamin E for 1 week, and alcohol for 3 days before injections. Mild headaches may occur and usually resolve with Tylenol. A slight change in the shape of the eyebrow is possible. Drooping of the eyelid is rare and usually resolves within a few days to weeks.

What Should I Do After Treatment?

It is important to utilize the treated area for the first 3 hours to facilitate the uptake of the botulinum toxin injection. Mild exercise is allowed 4 hours after the treatment.
