It is usually sold as a solution or medicated soap, sometimes in combination with benzyl benzoate. Sulfiram is now rarely used, but, , is still available in Brazil, India, and South Africa (as monotherapy). Adverse effects Dizziness, headache, fatigue and erythematous rash may occur. A single case of toxic epidermal necrolysis was reported in 1968. Sulfiram is structurally related to disulfiram (Antabuse), and readily converts to disulfiram when exposed to light.
