A 55 year old male, with uncontrolled diabetes mellitus and hypertension, developed severe air-borne contact dermatitis. The most appropriate drug for his treatment would be –: (A) Systemic corticosteroids, (B) Thalidomide, (C) Azathioprine, (D) Cyclosporine
Answer is C. Treatment of Allergic contact dermatitis


Topical corticosteroids in combination with oral antihistaminics are effective in most cases.
Extensive contact dermatitis may require treatment with a short course of oral corticosteroids.
In air-borne contact dermatitis, azathioprine may be effective.

As corticosteroids are contraindicated in patients with DM and hypertension, best option here would be azathioprine
