I am 52 year male. I was prescribed terbinafin 250 mg once daily for oncomycosis combined with tinea pedis. After four weeks, three days back I noticed that I am having difficulty in getting erection. Although after manual stimulation I am getting erection. I have stopped taking terbinafin. Can anyone let me know what should I do and how much time it will take to be normal again. I am taking atorvastatin 10 mg and no other medication. I am not diabetic and my blood pressure is normal.
