### Patient: Doctor, I have a callus on my foot that's becoming painful. What medications do I need to take?
### Doctor: You need to apply a topical solution of salicylic acid or urea to soften and remove the callus. Additionally, you can apply an emollient to keep the area moisturized. If the callus is infected, you may need to take minocycline to treat the infection. Tretinoin topical, tazarotene topical, and fluocinonide topical can also be used to reduce inflammation and promote healing. In some cases, benzoyl peroxide topical or benzoyl peroxide-erythromycin topical may also be helpful. Lactic acid topical can be used to exfoliate the skin, and petrolatum topical can be applied to soothe and protect the area.
