Can Botox Be Used on a Patient with Level 3 Kidney Disease?

As long as your nephrologist has no issues with you having Botox for cosmetic reasons, the number of units is very low and the effect localized to the muscle injected except for very rare instances, there should be a good possibility of a patient with kidney disease having safe Botox treatment.

There is no clinical evidence that botulinum toxins such as Botox, Dysport or Xeomin is contraindicated in patients with kidney or liver diseases.

Botox is not contraindicated in patients with chronic kidney disease (CKD). We routinely use Botox for cosmetic (wrinkles) and therapeutic indications (hyperhidrosis, migraine headaches) in patients with chronic kidney disease. 

With cosmetic doses of Botox, almost all of the Botox injected in a particular area is permanently bound in tissue within the first 1-3 hours.  There is no problem using it in patients with kidney disease.

I don't see any problem for you. But to be sure, consult your renal physician and also ask Allergan directly.
