Call 911 now: lips, mouth, throat or tongue swelling, or struggling to breathe, after a cream or tablet.
Urgent care or your doctor today: skin on the foot or leg that is painful, hot and swollen. Contact a doctor right away, especially with red streaks, pus or a fever.
Stop the tablets and call the doctor or urgent care now: yellow skin or eyes, pale poop and dark pee, while on terbinafine.
Your doctor: athlete's foot or a fungal nail with diabetes or a weakened immune system.
Your doctor: pharmacy treatment has not worked, a lot of pain, the rash spreads to the hands, or the nail infection spreads to other nails.
Your doctor: not better in 2 to 4 weeks on the feet, or 2 weeks on the groin.
