Addiction, abuse, and misuse
- On September 2020, FDA addressed serious risks of benzodiazepine addiction, abuse, and misuse, which can lead to overdose and death
- Physical dependence can occur when taken steadily for several days to weeks, even as prescribed
- Stopping abruptly or reducing dosage too quickly can result in withdrawal reactions, including seizures, which can be life-threatening
- Assess each patient’s risk prior to prescribing and monitor regularly for the development of these behaviors or conditions
Contraindications
