Minimal. Botulinum toxin is a deadly poison in large doses because it can paralyze vital muscles used in breathing and swallowing. In the very small doses used in cosmetic treatments, there have been no serious incidents. Bruising, drooping and rarely, blurred and double vision are realistic risks. Counterfeit products could be a problem. Going to an experienced, licensed injector is your best protection.
Not Really Dangers.. There are some minimal risks when using botox. Bruising (<5%), swelling, discomfort, headache, eyelid or brow drooping (exceedingly rare). Of course any medication taken inappropriately can have serious side effects. Botox has a very safe track record now for 20+ years. You should avoid Botox while pregnant or breast feeding and if you have any neurological conditions. Hope this helps!
Minor bruising. No long term or systemic side effects have been documented in cosmetic uses of Botox (less than 200 units). Botox therapy is a safe and effective for excessive wrinkling due to facial expression muscles. Beyond minor local swelling and discomfort during injection, the most common side effect is occasional mild bruising. Temporary eyelid droop and headaches are rarely reported.
Minimal. Most problems are related to bruising and swelling from the needle. Occasionally some muscle other than the intended target can be affected. Those deaths that occurred a long time ago now were related to greedy people using research Botox that was never intended for humans.
Botox safer thanASA? Is Botox safer than aspirin? Maybe. The risks of this product are relatively low given over 20 years of use. Despite this there are highly publicized related & unrelated adverse outcomes & perhaps more out there that are yet to be described. It is a natural product derived as a toxin from a bacteria. It blocks neurotransmitters and therefore its use by inexpereinced individuals can cause problems.
Botox complications. High doses may increase the risk of Botox complications, especially when used for neurological indications compared with cosmetic cases. There are a few serious complications including problems swallowing when high units have been used in the neck area. Extremely rarely, there could be nausea and flulike symptoms but this was seen in placebo treated study patients too.
