I don’t know, but the compounding pharmacy would tell me if I asked. You can call a compounding pharmacy and ask what “ recipes” they have for pain cream. Ask specifically about the Lido. I don’t know if that will actually make sense, since it’s blended with other medications in a base. I’ve had two different recipes - one had so many ingredients that it seemed sticky.
I shared the recipe with my neurologist, he was happy to have that, and the phone number for the pharmacy.
Doctors really want to help!
