βš•οΈ

Dose Adjustments

Renal Impairment:

Mild: No specific adjustment typically required.
Moderate: No specific adjustment typically required, but use with caution.
Severe: Use with caution; consider lower doses and monitor for increased sedation due to accumulation of active metabolites.
Dialysis: Diazepam is highly protein-bound and not significantly removed by dialysis. Use with caution and monitor for effects.

Hepatic Impairment:

Mild: Consider lower initial doses and titrate carefully.
Moderate: Reduced dose (e.g., 50% of usual dose) and careful monitoring are recommended due to impaired metabolism and prolonged half-life.
Severe: Contraindicated in severe hepatic insufficiency due to risk of precipitating encephalopathy.

Pharmacology

πŸ”¬

Mechanism of Action

Diazepam enhances the effect of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, at the GABA-A receptor. It binds to specific benzodiazepine sites on the GABA-A receptor complex, leading to an increased frequency of chloride channel opening. This results in neuronal hyperpolarization, which inhibits neuronal excitation, producing anxiolytic, sedative, hypnotic, anticonvulsant, and muscle relaxant effects.
πŸ“Š

Tmax: IV: 1-5 minutes (onset of action); IM: 0.5-1.5 hours (for peak plasma concentration, but highly variable)
FoodEffect: Not applicable for IV/IM administration. For oral, food can delay absorption but not significantly affect extent.

Distribution:

Vd: 0.8-1.0 L/kg (adults); higher in neonates and infants
ProteinBinding: 98% (primarily to albumin)
CnssPenetration: Yes (highly lipophilic, rapidly crosses blood-brain barrier)

DurationOfAction: Acute anticonvulsant/sedative effect: 15-60 minutes (due to rapid redistribution); Clinical effects can persist for several hours due to active metabolites.

Safety & Warnings

⚠️

BLACK BOX WARNING

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation. The use of benzodiazepines, including diazepam, exposes patients and other users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. Before prescribing diazepam, assess each patient’s risk for abuse, misuse, and addiction. The continued use of benzodiazepines, including diazepam, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher doses. Abrupt discontinuation or rapid dosage reduction of diazepam after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue diazepam or reduce the dosage.
⚠️

  • Oral contraceptives (may inhibit diazepam metabolism).
  • Theophylline (may antagonize benzodiazepine effects).
🟒

Minor Interactions

  • Not available

Monitoring

πŸ”¬

Baseline Monitoring

Respiratory rate and depth

Rationale: To assess baseline respiratory status, especially before IV administration, due to risk of respiratory depression.

Timing: Prior to administration

Blood pressure and heart rate

Rationale: To establish baseline cardiovascular status; IV administration can cause transient hypotension.

Timing: Prior to administration

Level of consciousness/Sedation score (e.g., Ramsay Sedation Scale)

Rationale: To assess baseline neurological status and guide dosing.

Timing: Prior to administration

Liver function tests (ALT, AST, bilirubin)

Rationale: Diazepam is extensively metabolized by the liver; baseline assessment is important, especially in patients with hepatic impairment.

Timing: Prior to initiation of prolonged therapy or in patients with suspected liver disease

Renal function (BUN, creatinine)

Rationale: Metabolites are renally excreted; important for patients with renal impairment.

Timing: Prior to initiation of prolonged therapy or in patients with suspected renal disease

πŸ“Š

Routine Monitoring

Respiratory rate and depth

Frequency: Continuously during and immediately after IV administration; frequently during acute treatment.

Target: Normal for age; avoid bradypnea (<10 breaths/min in adults)

Action Threshold: Significant decrease in respiratory rate, shallow breathing, or signs of respiratory distress (e.g., cyanosis); administer naloxone if opioid co-administration suspected, consider flumazenil if benzodiazepine overdose.

Blood pressure and heart rate

Frequency: Frequently during and immediately after IV administration; periodically during acute treatment.

Target: Within patient's normal range; avoid significant hypotension or bradycardia.

Action Threshold: Significant drop in BP or HR; symptomatic hypotension.

Level of consciousness/Sedation score

Frequency: Continuously during and immediately after IV administration; frequently during acute treatment.

Target: Desired level of sedation (e.g., calm, drowsy but arousable); avoid unarousable sedation.

Action Threshold: Excessive sedation, unresponsiveness, or paradoxical reactions (e.g., agitation, aggression).

Injection site for irritation/thrombophlebitis

Frequency: Visually inspect during and after IV administration.

Target: No redness, swelling, pain, or induration.

Action Threshold: Signs of irritation or thrombophlebitis; discontinue infusion at site and apply warm compress.

Liver function tests (ALT, AST, bilirubin)

Frequency: Periodically (e.g., every 6-12 months) for patients on prolonged therapy.

Target: Within normal limits.

Action Threshold: Significant elevation (e.g., >3x ULN); consider dose reduction or discontinuation.

πŸ‘οΈ

Symptom Monitoring

  • Excessive sedation or drowsiness
  • Dizziness or lightheadedness
  • Ataxia or unsteadiness
  • Slurred speech
  • Difficulty breathing or shallow breathing
  • Paradoxical reactions (e.g., agitation, anxiety, hallucinations, aggression, rage)
  • Memory impairment (anterograde amnesia)
  • Signs of withdrawal upon abrupt discontinuation (e.g., seizures, tremors, anxiety, insomnia, muscle cramps)

Special Patient Groups

🀰

Pregnancy

Diazepam is classified as Pregnancy Category D, indicating positive evidence of human fetal risk. It should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

Trimester-Specific Risks:

First Trimester: Increased risk of congenital malformations (e.g., cleft lip/palate) if used during the first trimester, though data are conflicting.
Second Trimester: Risk of fetal exposure and potential for withdrawal symptoms in the neonate if used chronically.
Third Trimester: Risk of 'floppy infant syndrome' (hypotonia, lethargy, hypothermia, respiratory depression, feeding difficulties) if used late in pregnancy or during labor. Risk of neonatal withdrawal symptoms (e.g., hypertonia, irritability, tremors, feeding difficulties, seizures) if used chronically during the third trimester.
🀱

Lactation

Diazepam and its active metabolites are excreted into breast milk. The American Academy of Pediatrics considers it a drug for which the effect on the nursing infant is unknown but may be of concern. Use with caution.

Infant Risk: L3 (Moderately Safe). Potential for sedation, lethargy, poor feeding, and weight loss in the infant. Monitor breastfed infants for drowsiness, poor feeding, and developmental milestones. Consider alternative agents or temporary cessation of breastfeeding if significant infant effects are observed.
πŸ‘Ά

Pediatric Use

Use with caution, especially in neonates and young infants, due to immature metabolic pathways and increased sensitivity to CNS depressant effects. Dosing must be carefully calculated based on weight and age. Prolonged use can lead to physical dependence and withdrawal.

πŸ‘΄

Geriatric Use

Elderly patients are more sensitive to the effects of benzodiazepines and have a prolonged elimination half-life of diazepam and its active metabolites due to decreased hepatic metabolism. This increases the risk of excessive sedation, respiratory depression, cognitive impairment, and falls. Lower initial doses and careful titration are recommended. Avoid long-term use if possible.

Clinical Information

πŸ’Ž

Clinical Pearls

  • IV diazepam should be administered slowly (max 5 mg/min) into a large vein to minimize the risk of venous irritation, thrombophlebitis, and local pain.
  • Do not mix or dilute diazepam injection with other solutions or drugs in the syringe or infusion bottle, as precipitation may occur.
  • IM administration of diazepam is generally not recommended for acute indications due to erratic and slow absorption; IV route is preferred for rapid effect.
  • Patients should remain recumbent for at least 30 minutes after IV administration due to potential for hypotension and sedation.
  • Tolerance and physical dependence can develop with chronic use; withdrawal symptoms can be severe and life-threatening if discontinued abruptly.
  • Paradoxical reactions (e.g., excitement, agitation, hallucinations) can occur, especially in pediatric, geriatric, or psychiatric patients.
πŸ”„

Alternative Therapies

  • For acute anxiety/agitation: Lorazepam (IV), Midazolam (IV)
  • For status epilepticus: Lorazepam (IV), Midazolam (IM/buccal/nasal), Phenytoin (IV), Fosphenytoin (IV), Levetiracetam (IV)
  • For muscle spasms: Baclofen, Tizanidine, Cyclobenzaprine
  • For alcohol withdrawal: Lorazepam (IV/oral), Oxazepam (oral), Chlordiazepoxide (oral)
