Frequently asked questions
How long does local anaesthetic last?
It depends on the drug and site — typically from about an hour (lidocaine) to several hours (bupivacaine).
Is numbing cream safe for children?
Yes, in the right amount for their size before procedures, but too much over broken skin can be absorbed — follow instructions.
