Possible Side Effects of Benzodiazepines

Like any other drugs, benzodiazepines also have side effects. Here are the things you should be cautious about:

1. General Side Effects

You may notice different side effects from different types of benzodiazepines, but most of them cause dizziness, sedation, unsteadiness and weakness. Some other side effects include headaches, loss of orientation, a feeling of depression, confusion, sleep disturbance, aggression, memory impairment and excitement. During the first few days of treatment, it is quite common to experience transient drowsiness as well.

2. Drug Interaction

Oral benzodiazepines interact with substances and medications that depress the brain like barbiturates, narcotic analgesics, alcohol, hypnotics and sleep medications.

You may also experience excessive sedation, drowsiness, lethargy and coma.

They sometimes also add another benzodiazepine to the prescription. Keep in mind that a cross-tolerance exists between benzodiazepines and some other depressants such as barbiturates and alcohol, which means the effects of the drugs may not be that noticeable.
