Botox Benefits

For most patients, the effects of Botox become apparent in terms of diminished muscle activity within 2-3 days.  The effects gradually wear off over the following 2-3 months, and generally there is no residual muscle paralysis after 3-4 months.  For this reason, most patients return every 3-4 months for re-treatment.

Some patients seem to require less Botox at subsequent treatments, perhaps because there is some muscle atrophy as a result of loss of nerve stimulus due to the Botox.  There is no limit as to how long a patient can continue to receive Botox treatments.

Botox selectively inhibits acetylcholine release at the neural synapse. When injected, the botox binds to the receptor and prevents the release of acetylcholine.  However, there is still remaining acetylcholine that has already been released. It takes about 5 days for the remaining acetylcholine to be used up. So, it takes about 5 days for the effects to take effect.
