Approved by the Food and Drug Administration (FDA) for the treatment of chronic migraines. This therapy works best for people who have headaches at least 15 days a month. Most of the reported side effects are mild and fleeting. They include pain, swelling, or minor bruising at the injection site, plus headache and flu-like symptoms for the first 24 hoursSometimes, temporary weakness and sagging of the face may also occur.
Benign side effects are well-localized, reversible, self-limiting complications that appear within a few days of injection and usually go away without treatment. Headache is a common short-term side effect, as the toxin initially causes muscle spasms and then total paralysis. There are no long-term or potentially fatal adverse effects related to botulinum toxin treatment for any cosmetic indication. Most Botox side effects usually go away after a few days or weeks as the effects of the injection wear off.
The toxic effects of Botox can sometimes spread from the area where the injections* are given and cause a condition called botulism. It seems important to obtain adequate knowledge about all possible adverse effects, their mechanisms and ways to prevent them. Cosmetic treatment of wrinkles and cervical lines often requires higher doses of botulinum toxin and increases the risk of serious side effects. In some cases, this effect may have a more positive effect; other research has found that the inability to frown can help patients suffering from depression.
Usually, the toxic effects of botulinum toxin can appear on the tenth or eleventh injection, after previous injections without complications. In addition to complications at the injection site, there is a group of aesthetic and functional adverse effects associated with different muscle responses to botulinum toxin or to the poor placement of botulinum toxin. Other mild side effects of Botox may vary depending on the condition the medication is being used for. In studies, this side effect was reported in people who received Botox for migraine, axillary hyperhidrosis, limb spasticity, and cervical dystonia.
On the other hand, immunoresistance in the cosmetic use of botulinum toxin increases the risk of serious dose-dependent side effects. When you're younger, receiving mini-doses of Botox (also known as Botox for babies) can have a preventive effect, as it prevents wrinkles from developing as quickly or intensely. Methods to prevent bruising include applying ice to the area before the injection, which causes vasoconstrictive effects, and also making sure that the patient is not taking any anticoagulant medication, such as warfarin or aspirin, and that he does not have any underlying coagulation problem. Upper respiratory tract infection is the most common side effect in children who use Botox for this condition.
