Topical administration of medications for pain management has become increasingly more common. Pharmaceutical companies are getting in the game with products such as Flector patches, Voltaren gel, Pennsaid topical solution, Lidoderm patches, and Qutenza patches. Numerous over-the-counter products also exist.
Many patients need more than just one medication to treat their pain. And for some, the adverse effects and allergies of oral medications is too much to bear. For these patients, sometimes the best solution is having a compounding pharmacy put together a number of different medications with different mechanisms of action into a compounded cream that is applied directly over the site of pain.
Benefits of Compounded Creams

- Minimizes systemic absorption
