Clonazepam, marketed under names like Klonopin, is a benzodiazepine used to treat seizures, panic disorders, and anxiety. Although certain websites may advertise the availability of Clonazepam overnight without a prescription, obtaining it this way can lead to significant health and legal risks. Unsupervised use may cause sedation, dependency, and withdrawal complications. It's critical to obtain this medication legally through a qualified physician to ensure proper usage and monitoring.
