A method of producing a compounded medication may include formulating a compounded transdermal cream that includes combining a diclofenac sodium solution and a lidocaine and prilocaine cream. The diclofenac sodium solution may be combined in an amount providing a diclofenac concentration of between approximately 0.1% and approximately 0.75% by weight of the compounded transdermal cream. The lidocaine and prilocaine cream may be combined in an amount providing an approximate equivalent concentration of each of lidocaine and prilocaine between approximately 1.5% and approximately 2.25% by weight of the compounded transdermal cream.
