I have been prescribed terbinafine tablets for toe nail infection. 5 weeks into taking the I woke to by body being covered in a rash. It says a rash could be a side effect of the tablets. I don t want to particularly stop taking them but thought I would continue and monitor if the rash worsens or becomes uncomfortable especially as the toe is painful and it is nigh on impossible to get a doctors appointment outside work hours and being self employed and risk of permanent loss of customers if appointments have to be cancelled I cannot attend during the day even then it can be a week or more wait.
