Botox injections are a cosmetic procedure commonly used to reduce the appearance of wrinkles and give skin a more youthful appearance. Botox is made with low concentrations of botulinum toxin type A, the same bacterial toxin that can cause botulism. However, when it is used in small doses it blocks the signal that causes muscles to contract, which reduces the appearance of wrinkles. Botox injections are the most common cosmetic procedure performed in the United States according to the Consumer Guide to Plastic Surgery. It can also be used to treat a variety of other medical conditions. Although Botox is usually safe when used properly, there are some risks associated with the procedure.
Botulism
Because Botox is derived from the same bacterial cells that can cause the deadly disease botulism, there is some risk of developing the condition if the injections are not administered properly. Signs and symptoms of botulism include muscle weakness, loss of strength, blurred or double vision, loss of bladder control and voice hoarseness.
Botulism can develop within hours of receiving Botox, but it may also develop weeks after treatment. To prevent serious complications, the Mayo Clinic recommends only receiving Botox injected from licensed physicians who have experience with Botox treatment. Look for doctors who are board-certified in cosmetic surgery, dermatology or otolaryngology.
Respiratory Difficulty
Another rare but potentially life-threatening side effect of Botox is developing difficulty breathing or swallowing. In severe cases, the condition can be fatal. These effects are more likely to develop in someone who already had problems with swallowing or breathing, so it's important to fully discuss the potential risks of Botox injections with your doctor before proceeding with treatment.
Other Side Effects
Many people will not experience any side effects as a result of Botox injections. However, the injections do have several known side effects, including pain and irritation at the injection site, headaches, temporary drooping of the facial muscles or weakness of the facial muscles, nausea and flu-like symptoms. These side effects are temporary and typically will resolve within a day or two or receiving the injections.
