The BDZs can have some side effects, such as sedation and some short-term memory loss, but a larger concern is that benzodiazepines can be addictive.
Therefore, it is very important to take them as prescribed and to not just stop taking them. Withdrawal from BDZs can be dangerous and difficult, even resulting in seizures or death. They should be slowly tapered off of, not abruptly stopped.
BDZs can also cause birth defects, so it is important for women taking BDZs to be on birth control or to practice other safe sexual practices to prevent pregnancy. Finally, do not take BDZs and drink alcohol at the same time.
The depressant effects of alcohol and the inhibitory effects of BDZs can have a negative effect on motor activity and can make driving dangerous, not to mention having a significant depressant effect on the central nervous system that can potentially result in a shutdown of basic bodily functions, such as breathing.
