Patient on allergen immunotherapy developed systemic lupus erythematosus?– A clinico-pharmacological look out

Drug induced lupus is an autoimmune condition secondary to drug exposure which leads to development of systemic lupus erythematosus (SLE). However, labelling the culprit drug needs a prudent insight into the pharmacological plausibility of each of the offending drugs in suspicion. Here we present a report where allergen immunotherapy was suspected to cause SLE and a deeper clinico-pharmacological evaluation cleared the air.
