Promethazine has been reported to be misused in conjunction with opioids in several settings. Promethazine misuse by itself or in conjunction with opioids may have serious adverse health effects. To date, no prevalence data for the nonmedical use of promethazine have been reported. This study examines the prevalence and correlates of promethazine use in 2 different populations in San Francisco, California: methadone maintenance clinic patients and community-based injection drug users (IDUs). ⋯ The finding that one-quarter of methadone maintenance patients in a clinic or recruited in community settings have recently used promethazine provides compelling evidence of significant nonmedical use of promethazine in this patient population. Further research is needed to establish the extent and nature of nonmedical use of promethazine.

Case Reports
Concerns about pregabalin: further experience with its potential of causing addictive behaviors.
Pregabalin (PRG) is approved for the treatment of neuropathic pain, partial seizures, and generalized anxiety disorder in many countries. Supported by case reports and a few studies there is an ongoing debate on PRG's potential to cause addictive behaviors. Considering that PRG is currently under investigation for the treatment of benzodiazepine dependence and withdrawal as well as relapse prevention in alcohol dependence, assessment of PRG's abuse and dependence potential is indispensable. ⋯ During reduction of PRG, the patient developed a moderate withdrawal syndrome with vegetative symptoms. Because of the early detection of the developing PRG abuse (4 months after first application of PRG), the development of PRG dependence was prevented. This case illustrates the possibility of PRG to trigger the development of addictive behaviors and should encourage physicians to be very careful when administering PRG to patients with current or past substance-related disorders.
