Hi there, This is Dr Basu, Experienced Specialist. I am here to address your concerns and provide great service.
No terbinafine will not cause psoriasis.
However, terbinafine can give rise to different types of rash from allergic reaction.
But psoriasis is not reported.
Terbinafine can worsen psoriatic rash if you already have psoriasis.
Usually a strong steroid cream or oral steroid will be helpful in that case.
It was my pleasure to help you today.
