How is onychomycosis treated?
Whether to treat a fungal nail infection is up to you. If it is not treated, it won't go away, and it might get worse. But fungal infections can be hard to treat. If you do treat it, you could spend a lot of money, and the treatment might not work.
If you decide to treat a fungal nail infection, you can try an antifungal cream, lotion, or nail polish. You can buy some types without a prescription, or your doctor can prescribe a stronger one. You may need to use this medicine for a few weeks or for as long as a year. Even so, it may not get rid of the infection.
Antifungal pills give the best chance of curing a severe fungal nail infection, but they may cost a lot and have serious side effects. You will need to see your doctor for regular testing if you take these pills. You should not take them if you have liver or heart problems.
