The botulinum toxin contained in this medication can spread to other body areas beyond where it was injected. This has caused serious life-threatening side effects in some people receiving botulism toxin injections, even for cosmetic purposes.
Call your doctor at once if you have drooping eyelids, vision problems, severe muscle weakness, loss of bladder control, or trouble breathing, talking, or swallowing. Some of these effects can occur up to several weeks after a botulinum toxin injection.
Botulinum toxin injections should be given only by a trained medical professional, even when used for cosmetic purposes.
Do not seek botulinum toxin injections from more than one medical professional at a time. If you switch healthcare providers, be sure to tell your new provider how long it has been since your last botulinum toxin injection.
Using this medication more often than prescribed will not make it more effective and may result in serious side effects.
You should not receive this medication if you are allergic to botulinum toxin, or if you have an infection, swelling, or muscle weakness in the area where the medicine will be injected.
Before receiving a botulinum toxin injection, tell your doctor if you have ALS ( Lou Gehrig’s disease), myasthenia gravis, Lambert-Eaton syndrome, or heart disease.
The effects of a botulinum toxin injection are temporary. Your symptoms may return completely within 3 months after an injection. After repeat injections, it may take less and less time before your symptoms return, especially if your body develops antibodies to the botulinum toxin.
