Do Botox injections contain sulfa?

In Botox?Botox is a purified protein that blocks the chemical acetylcholine and can relax muscles leading to a reduction in wrinkles and lines on the face. I am not aware that Botox contains any sulfa particles.

There are a few different brands of neuromodulators.  None of them contain Sulfa to my knowledge, and I use Botox commonly in patients with various antibiotic allergies. You can always request the packaging and ingredients information directly from the manufacturer if you need more specifics.  If you have a Sulfa allergy, make sure that you mention it to the doctor.All the best,

Sulfa-allergic patients can undergo Botox injections.
