Answer

Drug eruptions can mimic a wide range of dermatoses. The morphologies are myriad and include morbilliform (most common, see image below), urticarial, papulosquamous, pustular, and bullous. Medications can also cause pruritus and dysesthesia without an obvious eruption. Both calcium channel blockers and interferon are strongly associated with eczematous eruptions.
