Cocaine is also highly pyrogenic, because the stimulation and increased muscular activity cause greater heat production. Heat loss is inhibited by the intense vasoconstriction. Sometimes seizures may occur. Anxiety, paranoia and restlessness are also frequent. Stroke, seizures, fever, infection, kidney failure, liver hepatitis, pneumonia, thrombophlebitis (clotting of the veins), and HIV are other potential complications of cocaine use and cocaine overdose.
