Written & medically reviewed by Dr. Sanjay Anbu, MBBS · Last reviewed 5 November 2026

Diazepam is used for anxiety, muscle spasm, seizures and alcohol withdrawal, short-term. It belongs to the Sedative / anti-anxiety (benzodiazepine group) group. These calm the nervous system for short-term anxiety, sleep or seizures. They can cause dependence, so they are used carefully and short-term.

Frequently asked questions

Why does diazepam make me drowsy the next day?

Diazepam is long-acting and leaves the body slowly, so drowsiness can carry over. Avoid driving or machines if you feel slowed.

Can diazepam be used for muscle spasm?

Yes, it relaxes muscles and is sometimes used briefly for painful spasm, as well as for anxiety and alcohol withdrawal.

Is it safe to take diazepam for a long time?

Long-term use can cause dependence and tolerance. It is usually prescribed for short periods and stopped gradually.
