Question: Would 10% lidocaine U.S.P be safe to use on my penis?

 thorntor - Sat Oct 31, 2009 5:14 pm

Recently i bought some spray, called SuperDragon 6000, which can be found here i've searched on google about the lidocaine part but can only find stuff like the 5% Topical patches, Would 10% be too much or okay to use?

User avatar Hi,
Lidocaine 3.5% and 5% have been studied (and being studied) for their efficacy in neuropathic pains and for post operative analgesia.

As the % increases, potential for local and systemic toxicity increases proportionately.
So far,there has not been widespread inclination or need to put 10% lidocaine through trials. 5% lidocaine appears to be satisfactory enough for most purposes.

If one is trying to use topical lidocaine for delaying ejaculation i would strongly advise against it and would like to warn that even potential for mortality from respiratory arrest exists as the % is hiked up.
Best wishes!
