thanks for the query.

Terbinafine is an antifungal drug with a known history of cutaneous allergic reactions in people who are allergic to it. Skin itch, swellings and ulceration are typical of drug reactions and in severe forms may present with skin ulcerations or especially around body cavities such as the mouth.

Terbinafine has a variable half life but most importantly, the first thing to do is to stop taking it and never do take it again as the nest time symptoms may be worst.

Psoriasis is a chronic skin disease which typically comes and goes and presents with thick silvery scales on red patches, Thickened and ridged nails, swollen and stiff joints etc.

The precise cause of psoriasis is unknown but it is believe that the immune system malfunctions and interacts with the environment to cause psoriasis. Risk factors include family history which is seen in up to 40% of people with psoriasis, tobacco, stress, obesity, HIV and bacterial infections, drug reactions etc.

Treatment options vary from
-topical agents such as; corticosteroids, retinoids, salycylic acid, coal tar etc
-phototherapy using uv light
-oral or injectable agents such as retinoids, methotrexate, cyclosporine, hydroxyurea, infliximab etc.
Your treating dermatologist will know these drugs and will choose his that is more confident in.

more importantly, lifestyle modifications are very important such as daily bath, useof medicated prednisolone creams or salicylic acid creams, exposure of affected areas to sunlight, avoid triggers of psoriasis such as drugs and others in your case and avoid alcohol.
Hope this answers your query. If you have further query, i will be ready to help.
Best regards.
