Over-the-counter treatments for jock itch that contain clotrimazole, miconazole, terbinafine and tolnaftate are equally effective, according to Drugstore.com. Among the brand names of such treatments are Lotrimin, Micatin and Lamisil. Most of these treatments come in cream, lotion or powder form.
Jock itch is most commonly caused by a fungal infection, though bacteria may also be a cause. The over-the-counter treatments for jock itch are all antifungal treatments; if a bacterial infection is also involved, treatment may require prescription antibiotics, as WebMD explains. Other home treatments for jock itch include drying the area thoroughly after bathing, wearing loose-fitting clothing, and applying hydrocortisone cream and zinc oxide ointment.
