Botox is a popular cosmetic treatment that has been approved by the Food and Drug Administration (FDA) for the treatment of chronic migraines. This therapy works best for people who have headaches for at least 15 days a month. While there are no long-term or life-threatening adverse effects related to botulinum toxin treatment for any cosmetic indication, it is important to be aware of the potential risks associated with this procedure. The effects of administering different botulinum neurotoxin products at the same time or several months apart from each other is unknown.
Excessive neuromuscular weakness may be aggravated by administration of another botulinum toxin prior to resolution of the effects of a previously administered botulinum toxin. Usually, the toxic effects of botulinum toxin can appear on the tenth or eleventh injection, after previous uncomplicated injections. Certain anesthetic medications used during surgery may interact with Botox and possibly make Botox less effective. It is also possible that these or other Botox side effects last longer, such as a few days or weeks.
According to the authors, only 25% of patients did not experience any side effects during the course of treatment. The most common side effects associated with Botox include pain, swelling, and bruising at the injection site, as well as headache, flu-like symptoms, and nausea. In rare cases, more serious side effects such as difficulty breathing, blurred vision, drooping eyelids, and muscle weakness can occur. It is important to obtain the right knowledge about all possible adverse effects, their mechanisms and ways to prevent them.
If side effects seem life-threatening or if you think you're having a medical emergency, call 911 or the local emergency number immediately. The absence of warnings or other information for a given drug does not indicate that the drug or drug combination is safe, effective, or appropriate for all patients or for all specific uses. In addition, they cause muscle fibrosis after several years, although so far no such effect has been demonstrated in a shorter follow-up. If you have side effects that last longer than a few days or weeks, bother you, or worsen, talk to your doctor or pharmacist.
The U. S. Food and Drug Administration (FDA) describes adverse effects as serious if they meet strict criteria. Cosmetic treatment of cervical wrinkles and lines generally requires higher doses of botulinum toxin and increases the risk of serious side effects.
