Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances. Be sure to describe the symptoms you experienced.
If you are currently taking itraconazole or ketoconazole, as these medications may interact with this drug.
If you are taking any other medications that can cause drowsiness. There are numerous drugs that can have this effect, so consult your doctor or pharmacist if you are unsure.
If you are breastfeeding, as you should not breastfeed while taking this medication.
This list is not exhaustive, and it is crucial to discuss all your medications (including prescription, over-the-counter, natural products, and vitamins) and health issues with your doctor and pharmacist. They will help determine if it is safe to take this medication with your other medications and health conditions. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
After taking this drug, avoid operating a vehicle or engaging in any activities that require alertness, as it may cause drowsiness. This effect can persist into the next day, so refrain from such tasks until you feel fully awake and alert.
Prolonged nightly use of sleep medications like this one for more than a few weeks can lead to reduced efficacy in addressing sleep issues, a phenomenon known as tolerance. Therefore, it is recommended to use this medication for a short duration only. If your sleep problems persist, consult your doctor for further guidance.
If you are taking this medication long-term, your doctor may recommend regular blood tests to monitor your condition. Be sure to discuss this with your doctor.
Avoid consuming alcohol while on this medication, and do not take it if you have had alcohol that evening or before bedtime. Additionally, consult your doctor before using marijuana, cannabis, or any prescription or over-the-counter drugs that may cause drowsiness or impair your reactions.
Some individuals taking sleep medications have reported engaging in activities such as driving, cooking, eating, or having sex while not fully awake, often without any memory of these events. If you experience such episodes, inform your doctor promptly.
This medication can cause drowsiness and decreased alertness, increasing the risk of falls, particularly in older adults. If you have concerns, discuss them with your doctor.
If you are 65 years or older, exercise caution when taking this medication, as you may be more susceptible to side effects.
There is a potential risk of harm to the unborn baby if this medication is taken during pregnancy. If you become pregnant or suspect you are pregnant while on this medication, contact 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. It is crucial to discuss this with your doctor to understand the potential risks and benefits.
Overdose Information
Overdose Symptoms:
- Extreme drowsiness
- Confusion
- Slurred speech
- Slowed reflexes
- Lack of coordination (ataxia)
- Hypotension (low blood pressure)
- Respiratory depression (slow, shallow breathing)
- Coma
What to Do:
Seek immediate medical attention or call 911. For poison control, call 1-800-222-1222. Overdose treatment may include supportive care, maintaining airway, and administration of flumazenil (a benzodiazepine receptor antagonist) in severe cases, though flumazenil carries risks of withdrawal and seizures.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, nelfinavir) due to significantly increased estazolam exposure and risk of prolonged sedation and respiratory depression.
- Opioids (due to risk of profound sedation, respiratory depression, coma, and death; Black Box Warning).
Major Interactions
- Other CNS depressants (e.g., alcohol, barbiturates, other benzodiazepines, tricyclic antidepressants, antihistamines, antipsychotics, general anesthetics, skeletal muscle relaxants) due to additive CNS depressant effects.
- Sodium oxybate (concomitant use is contraindicated with other sedative hypnotics).
Moderate Interactions
- Moderate CYP3A4 inhibitors (e.g., erythromycin, diltiazem, verapamil, grapefruit juice) may increase estazolam levels and enhance its effects.
- Drugs that induce CYP3A4 (e.g., carbamazepine, phenytoin, rifampin) may decrease estazolam levels and efficacy.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To confirm diagnosis of insomnia and rule out underlying medical or psychiatric conditions.
Timing: Prior to initiation of therapy
Rationale: To identify risk factors for abuse, dependence, and contraindications.
Timing: Prior to initiation of therapy
Rationale: To assess baseline organ function, especially in elderly or patients with pre-existing conditions, as dose adjustments may be needed.
Timing: Prior to initiation of therapy (if clinically indicated)
Routine Monitoring
Frequency: Regularly during therapy, especially during initial weeks and dose adjustments
Target: Improved sleep parameters, reduced insomnia symptoms
Action Threshold: Lack of efficacy or worsening symptoms may indicate need for re-evaluation or alternative therapy.
Frequency: Regularly during therapy, especially during initial weeks and dose adjustments
Target: Absence or minimal tolerable side effects
Action Threshold: Significant or intolerable side effects may require dose reduction or discontinuation.
Frequency: Periodically, especially with prolonged use
Target: Absence of signs of dependence or withdrawal
Action Threshold: Development of tolerance or withdrawal symptoms upon dose reduction/discontinuation indicates dependence and requires careful tapering.
Frequency: As clinically indicated
Target: Normal respiratory rate and effort
Action Threshold: Respiratory depression requires immediate intervention.
Symptom Monitoring
- Excessive daytime drowsiness
- Dizziness
- Lightheadedness
- Ataxia (impaired coordination)
- Confusion
- Memory impairment (anterograde amnesia)
- Paradoxical reactions (e.g., agitation, aggression, hallucinations, worsening insomnia)
- Respiratory depression (especially with opioids)
- Signs of withdrawal upon discontinuation (e.g., rebound insomnia, anxiety, tremors, seizures)
Special Patient Groups
Pregnancy
Estazolam is Pregnancy Category D. It should not be used during pregnancy unless the potential benefit justifies the potential risk to the fetus. Benzodiazepines can cause fetal harm when administered to pregnant women.
Trimester-Specific Risks:
Lactation
Estazolam is excreted into breast milk. Due to the potential for sedation, feeding difficulties, and withdrawal symptoms in the breastfed infant, use is generally not recommended. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients (under 18 years of age) have not been established. Use is not recommended.
Geriatric Use
Elderly patients are more sensitive to the effects of benzodiazepines and are at increased risk for adverse effects such as excessive sedation, dizziness, ataxia, falls, and cognitive impairment. The initial dose should be reduced to 0.5 mg at bedtime, and the dose should be titrated carefully based on individual response and tolerability. Monitor closely for CNS depression.
Clinical Information
Clinical Pearls
- Estazolam is a short-to-intermediate acting benzodiazepine hypnotic, suitable for short-term management of insomnia.
- Due to its potential for abuse, dependence, and withdrawal, it should be prescribed for the shortest duration possible and at the lowest effective dose.
- Patients should be warned about the risk of complex sleep behaviors (e.g., sleep-driving, preparing and eating food, making phone calls) while not fully awake, with amnesia for the event.
- Rebound insomnia and withdrawal symptoms can occur upon abrupt discontinuation, especially after prolonged use. Tapering is crucial.
- Avoid concomitant use with alcohol and other CNS depressants due to additive effects and increased risk of respiratory depression.
- The Black Box Warning regarding concomitant opioid use is critical; educate patients thoroughly on this risk.
Alternative Therapies
- Other benzodiazepine receptor agonists (BZRAs) for insomnia: zolpidem, zaleplon, eszopiclone (non-benzodiazepine hypnotics)
- Other benzodiazepines for insomnia: temazepam, triazolam, flurazepam
- Melatonin receptor agonists: ramelteon
- Orexin receptor antagonists: suvorexant, lemborexant, daridorexant
- Antidepressants with sedative properties: trazodone, doxepin (low dose)
- Antihistamines: diphenhydramine, doxylamine (OTC, generally not recommended for chronic insomnia)
- Cognitive Behavioral Therapy for Insomnia (CBT-I) - often considered first-line non-pharmacological treatment.
