Treatment

• For the treatment of toenail fungus, doctors may prescribe oral or topical prescription medications.
  
  

Types

• Oral medications used for toenail fungal infections include terbinafine and itraconazole. Topical medications include a clear solution similar to nail polish called ciclopirox and urea skin creams.
  
  

Function

• Both the topical and oral antifungal medications work by preventing fungal cells from producing chemicals vital for the fungus to survive and reproduce. This eventually leads to their death and the end of the infection.
  
  

Time Frame

• Doctors typically prescribe oral medications for toenail fungus for six to 12 weeks, reports the Mayo Clinic. Ciclopirox lacquer requires about one year to completely eliminate an infection.
  
  

Risks

• Oral antifungal medications have the potential to cause common side effects like skin rashes and more serious complications like liver damage, warns the Mayo Clinic. Ciclopirox poses a risk for skin redness and swelling as well as changes in the shape or texture of your nails, cautions the U.S. National Library of Medicine.
