No: Terbinafine itself could not cause swelling or skin infection. The cephalexin is an antibiotic which is used to treat bacterial skin infections. The fungal infection and the bacterial infection are likely not related. Was the fungal infection of the finger or toe nails? Sometimes very bad fungal infections can leave breaks in the skin - this can allow bacteria to get inside and cause infection

Terbinafine/swelling: This is not classically described but would fill out a MedWatch report for FDA. Low white blood count is noted leading to infection with swelling, bleeding tendency is noted- could be hematoma. With swelling think of clot ( not previously noted, usually blood thinner) Consider sed rate,d-dimer level and/or sonogram to rule out clot/vasculitis. Also get CBC and CMP.. F/u with doc/urgent care.
