Dangers of Botox

Many people are familiar with the use of Botox® (onabotulinumtoxinA, previously known as botulinum toxin type A) for reducing the appearance of frown lines. However, the drug is approved for other uses, such as treating severe sweating and various muscle spasm conditions. Although most people respond well to Botox, dangers associated with its use should be reviewed with your healthcare provider.
As with any medicine, side effects are possible with Botox. Some of the most common reactions that have been reported with this drug (when used for cosmetic purposes) include droopy eyelids, muscle weakness, and facial pain. In studies of Botox for treating medical conditions rather than for cosmetic purposes, neck pain, headache, and difficulty swallowing were reported.
Other dangers associated with Botox include the risk of allergic reactions, heart problems, a decrease in blinking reflexes, or vision changes. In order to help ensure a safe treatment process, you should talk to your healthcare provider before using Botox if you have heart disease, a neuromuscular disease, or an infection near the site where you would receive the injections.
