If you experience changes in the frequency or severity of seizures after initiating this medication, promptly discuss these changes with your doctor.
This medication may cause drowsiness and reduced alertness, increasing the risk of falls, particularly in older adults. If you have concerns, consult your doctor to discuss potential strategies for minimizing this risk.
Do not alter the dosage or discontinue this medication without consulting your doctor, as this may lead to seizures. If you are taking this medication long-term, your doctor may recommend regular blood tests to monitor your condition.
Prolonged use of this medication or taking it at high doses may result in tolerance, reducing its effectiveness. If you suspect this medication is no longer working as intended, contact your doctor. However, do not exceed the prescribed dose, as this can lead to adverse effects.
Some formulations of this medication may contain benzyl alcohol. If you are administering this medication to a newborn or infant, it is crucial to avoid products containing benzyl alcohol, as it can cause severe side effects in these age groups, particularly when combined with other medications containing benzyl alcohol. Consult your doctor to determine if the prescribed product contains benzyl alcohol.
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects. Similarly, when administering this medication to children, exercise caution, as they may be at a higher risk of experiencing certain side effects.
This medication may pose risks to the unborn baby if taken during pregnancy. If you become pregnant or are planning to become pregnant, inform your doctor immediately. Taking this medication late in pregnancy may increase the risk of respiratory or feeding problems, low body temperature, or withdrawal symptoms in the newborn. Discuss the potential risks and benefits with your doctor.
Overdose Information
Overdose Symptoms:
- Extreme drowsiness or sedation
- Confusion
- Slurred speech
- Slowed reflexes
- Ataxia (loss of coordination)
- Hypotension (low blood pressure)
- Respiratory depression (slow, shallow breathing)
- Coma
What to Do:
Seek immediate medical attention. Call 911 or Poison Control at 1-800-222-1222. Overdose may require supportive care, including airway management and possibly flumazenil (a benzodiazepine antagonist), though flumazenil should be used with caution due to risk of seizures in dependent patients.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 and CYP2C19 inhibitors (e.g., ketoconazole, itraconazole, fluvoxamine, fluoxetine) due to increased diazepam exposure and risk of prolonged sedation.
- Opioids (concomitant use significantly increases risk of respiratory depression, profound sedation, coma, and death).
Major Interactions
- Other CNS depressants (e.g., alcohol, barbiturates, other benzodiazepines, general anesthetics, tricyclic antidepressants, antipsychotics, antihistamines, muscle relaxants) due to additive CNS depressant effects.
- Sodium oxybate (GHB) due to profound CNS depression.
- Cimetidine, omeprazole, esomeprazole (inhibit diazepam metabolism, increasing levels).
Moderate Interactions
- Antacids (may delay oral absorption, not relevant for injection).
- Disulfiram (inhibits diazepam metabolism).
- Oral contraceptives (may inhibit diazepam metabolism).
- Theophylline (may antagonize benzodiazepine effects).
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To assess baseline respiratory status, especially before IV administration, due to risk of respiratory depression.
Timing: Prior to administration
Rationale: To establish baseline cardiovascular status; IV administration can cause transient hypotension.
Timing: Prior to administration
Rationale: To assess baseline neurological status and guide dosing.
Timing: Prior to administration
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
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
Routine Monitoring
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.
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.
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).
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.
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.
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:
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.
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.
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
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.
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)
