Tuberculosis (TB) poses major health problem in developing countries including India. According to WHO in 2010 survey, there were about 9.4 million active pulmonary TB Patients worldwide, out of that 2.3 million case were found in India. Isoniazid is known to be the least toxic among the first line antitubercular drugs.  Hypersensitivity reactions due to Isoniazid may present in the form of fever and skin rash. We hereby report a case of acute generalised exanthematous pustulosis due to isoniazid in a patient on anti-tubercular treatment. We also established the causality, severity, and preventability of the suspected adverse drug reactions (ADRs).
