Benzodiazepines, also called Benzos, are among the most prescribed medications globally. These psychoactive drugs are hypnotic, sedative, and anxiety-reducing, effectively treating anxiety disorders, insomnia, seizures, alcohol withdrawal symptoms, and panic disorders. Commonly prescribed Benzos include lorazepam (Ativan), diazepam (Valium), clonazepam (Klonopin) and midazolam (Versed). Benzos are generally safe if taken in the short term under prescription. However, prolonged use of the drug will cause tolerance, dependence, abuse, withdrawal effects, and possible overdose. Here’s what you should know about common benzodiazepine side effects.
