Hard to : Overdose on topicals. Long term side effects of topical ketamine are minimal if any at all. Great old drug for neuropathic pain or for opiod tolerant patients.
Created for people with ongoing healthcare needs but benefits everyone.

Unlikely : It is very unliky that you will absorb enough topically administered Lidocaine and ketamine to achieve any significantly high blood levels which would lead to toxicity.
