Nicolau syndrome associated with fluphenazine depot: A case report

Nicolau syndrome is a rare condition characterized by severe pain at the site of injection, leading to ulceration and necrosis of the local tissues. Its presentation is usually acute. Nicolau syndrome is commonly seen in patients after intramuscular, intra-articular, or subcutaneous injections of non-steroidal anti-inflammatory drugs, antiepileptics, antipsychotics, antibiotics, antihistamines, and corticosteroids. Immediate diagnosis and management of this syndrome are of great importance. We herein report a rare presentation of Nicolau syndrome in a 36-year-old married male who suffered from paranoid schizophrenia for the past 3 years. The patient presented with dull pain, mild swelling, and necrotic ulceration over the injection site after receiving intramuscular fluphenazine. The patient underwent wound debridement and was given prophylactic antibiotics. Despite a wide range of therapeutic options for the management of Nicolau syndrome described in the literature, there exist limited guidelines for its management.
