Diazepam
Generic: diazepam · Brand: Valium® · Class: Anxiolytic — Benzodiazepine — Schedule IV
🧠
How It Works
Diazepam is a long-acting benzodiazepine with one of the longest half-lives of any benzodiazepine (20–100 hours) and active metabolites that extend its duration even further. It enhances GABA activity broadly, producing anxiolytic, muscle-relaxant, sedative, and anticonvulsant effects. Its very long half-life means less rebound anxiety between doses but also means it accumulates in the body with repeated use — especially in older adults where it can cause prolonged sedation. Used for anxiety, muscle spasms, alcohol withdrawal, and procedural sedation.

What It Treats
Anxiety DisordersFDA-approved for short-term anxiety management
Alcohol WithdrawalFDA-approved; long half-life makes it ideal for managing withdrawal symptoms
Muscle SpasmsFDA-approved for relief of skeletal muscle spasm
Seizure DisordersFDA-approved; rectal gel used for cluster seizures
Procedural SedationUsed before medical procedures to reduce anxiety and provide sedation

Dosing Overview
| Population | Start | Typical Range | Max |
|---|---|---|---|
| Adults Anxiety | 2–5 mg 2–4x daily | 4–40 mg/day | 40 mg/day |
| Adults Muscle Spasm | 2–10 mg 3–4x daily | 6–40 mg/day | 40 mg/day |
| Older Adults Avoid if possible | 2–2.5 mg 1–2x daily | 2–5 mg/day | 10 mg/day |
Taken with or without food. Long half-life means once or twice daily dosing is sufficient. Accumulates significantly in older adults — use with extreme caution or avoid. Available in tablet, liquid, and rectal gel formulations.

Side Effects
Common
- Sedation and drowsiness
- Dizziness
- Memory impairment
- Coordination problems
- Fatigue
- Slurred speech
- Muscle weakness
- Confusion
Call us if you notice
- Respiratory depression (especially with opioids or alcohol)
- Severe accumulation in elderly
- Falls and fractures
- Prolonged sedation
- Severe withdrawal if stopped abruptly
Diazepam's very long half-life is an advantage for smooth coverage but means it accumulates with regular use. In older adults, it can build up to dangerous levels causing falls and confusion. The Beers Criteria lists diazepam as inappropriate for routine use in adults over 65.

Important Safety Information
Dependence and Withdrawal: Benzodiazepines can cause physical dependence with regular use. Never stop abruptly — withdrawal can cause seizures, severe anxiety, and in rare cases can be life-threatening. Always taper slowly with your provider.
Alcohol is Dangerous: Combining benzodiazepines with alcohol or other CNS depressants can cause respiratory depression and death. Never mix these.
Opioid Combination — BLACK BOX WARNING: Combining benzodiazepines with opioids significantly increases the risk of respiratory depression, coma, and death. If you take any opioid medication, tell your provider immediately.
Impaired Driving: Benzodiazepines impair reaction time and coordination. Do not drive or operate heavy machinery until you know how this medication affects you.
Pregnancy: Benzodiazepines can cause fetal harm and neonatal withdrawal. Discuss risks and benefits carefully with your provider.
Tolerance Develops: The sleep and anxiety effects often diminish with regular use as tolerance develops. These medications are generally recommended for short-term use only.
Elderly Warning — Beers Criteria: Diazepam is listed on the Beers Criteria as a potentially inappropriate medication for adults 65 and older due to its very long half-life and high accumulation risk. Falls, cognitive impairment, and prolonged sedation are significant risks.
