Before you decide to take an oral antifungal medication to treat a
fungal infection such as
athlete's foot or a
fungal nail infection, you and your health
professional will want to consider the possible risks. Depending on the
medication and your particular risk factors, some antifungal
medications may:
- Affect liver or kidney function.
- Cause liver damage or failure, particularly when combined with
alcohol or certain medications.
- Weaken the
heart's ability to contract, leading to
heart failure.1
- Cause dangerous side effects
when combined with many different common medications.
During oral antifungal treatment, your health professional may
require blood tests to check your kidney and liver function.
Possible mild side effects caused by antifungal medications include
stomach upset, headaches, and skin rash.
