What is the risk of developing necrosis after Botox?

I have never seen necrosis after Botox injection. Side effects can include unwanted drooping of eyelids for example if injected initial the muscles involved in lis opening, facial nerve weakness in the distribution of the muscles of the face inbervated by the 7th nerve. The expectation is return of muscular function after the effects of Botox are gone, generally about 6 months after injection.

Botox is neurotoxin that inhibits muscle contractions. The side effects of Botox can include but are not limited to lazy eye, swelling, bruising, muscle weakness, etc. Necrosis, cell death, however, is not a common side effect of Botox.

The risk of developing necrosis from Botox injections would be extremely low. The most common side effects from Botox are minimal localized swelling and bruising. Botox is a very popular treatment in part because it works so well with very little risk. I encourage you to speak with your injector about any concerns you may have.

You are likely confusing Botox, which is used to treat dynamic (motion-related) wrinkles, with fillers injected in certain locations. Botox, whose consistency is like that of plain physiologic salt water, has therefore no chance of clogging blood vessels and hence NO risk for the development of necrosis. I have personally been treating patients for aesthetic purposes since 1991 and have never had a case of necrosis or seen one reported with Botox. Hopes this allays your concerns.

Thank you for sharing your question. The risk of necrosis with Botox is essentially zero. Hope this helps.
