Can I have Botox while taking erythromycin for a tooth infection?

You should be able to proceed with your Botox treatment if you are taking erythromycin for a tooth infection. If you have an active infection near the treatment area it is recommended to wait until the infection has resolved before having your Botox treatment.

Since botox is injected locally and remains in the muscles in which it is injected, there should be no problem to have it injected while on antibiotics. Botox is injected in small amounts and is not absorbed systemically requiring metabolism/excretion by the liver/kidneys, therefore it would not interfere with the metabolism of the antibiotic.

I would recommend you wait 1 week after you have completed your antibiotics before having any toxins
