Oral antifungal medicines may be used to treat a fungal infection, such as athlete's foot or a fungal nail infection. Before you decide to take this type of medicine, you and your doctor will want to consider the risks. Some antifungal medicines may:
- Affect liver or kidney function.
- Cause liver damage or failure, especially when combined with alcohol or certain medicines.
- Weaken the heart's ability to contract. This can lead to heart failure.
- Cause dangerous side effects when combined with many common medicines.
