Diazepam is a medication belonging to the benzodiazepine class, commonly used to treat anxiety, muscle spasms, and seizures. It works by enhancing the effects of a neurotransmitter called GABA, which helps calm the brain and nervous system. This drug is often prescribed for short-term use due to its potential for dependence and withdrawal symptoms. Diazepam can be taken orally, injected, or administered as a rectal gel, depending on the condition being treated. It is important to follow a healthcare provider's instructions when using this medication.
