It appears glucuronide conjugation of lorazepam is increased in the presence of combined hormonal oral contraceptives; the clinical significance of this interaction is not determined. Stable at room temperature for up to 24 hours. Consider the benefits of appropriate anesthesia in pregnant women against the potential risks, especially for procedures that may last more than 3 hours or if multiple procedures are required prior to delivery. The CNS depressant effects of topiramate can be potentiated pharmacodynamically by concurrent use of CNS depressant agents such as the benzodiazepines. General supportive and symptomatic measures are recommended; vital signs must be monitored and the patient closely observed. If concurrent use is necessary, initiate gabapentin at the lowest recommended dose and monitor patients for symptoms of respiratory depression and sedation. Particular caution is required in determining the amount of time needed after outpatient procedures or surgery before it is safe for any patient to ambulate. al. Dasabuvir; Ombitasvir; Paritaprevir; Ritonavir: (Moderate) Monitor for an increase in lorazepam-related adverse reactions and consider reducing the dose of lorazepam if concomitant use of lorazepam and dasabuvir is necessary. Patients should be instructed to avoid situations where drowsiness may be a problem and not to take other medications that may cause drowsiness without adequate medical advice. Educate patients about the risks and symptoms of respiratory depression and sedation. Suvorexant: (Moderate) CNS depressant drugs may have cumulative effects when administered concurrently and they should be used cautiously with suvorexant. Trihexyphenidyl: (Moderate) CNS depressants, such as anxiolytics, sedatives, and hypnotics, can increase the sedative effects of trihexyphenidyl. If an opiate agonist is initiated in a patient taking a benzodiazepine, use a lower initial dose of the opiate and titrate to clinical response. Ativan Oral Concentrate LORazepam Oral Concentrate Store inuse bottle in refrigerator. For example, the concomitant use of barbiturates and benzodiazepines increases sleep duration and may contribute to rapid onset, pronounced CNS depression, respiratory depression, or coma when combined with sodium oxybate. Monitor patients for decreased pressor effect if these agents are administered concomitantly. Patients should not drive or operate heavy machinery until they know how the combination affects them. Lorazepam in: ASHP Injectable Drug Information If an opiate agonist is initiated in a patient taking a benzodiazepine, use a lower initial dose of the opiate and titrate to clinical response. For elderly or debilitated patients, an initial dosage of 1 mg/day to 2 mg/day in divided doses is recommended, to be adjusted as needed and tolerated. In more serious cases, and especially when other drugs or alcohol were ingested, symptoms may include ataxia, hypotonia, hypotension, cardiovascular depression, respiratory depression, hypnotic state, coma, and death. Reported elimination half-lives are 12 hours, 14 +/- 5 hours, and 20.2 +/- 7.2 hours for immediate-release oral formulations, the parenteral formulation, and the extended-release capsules, respectively. Limit the use of opioid pain medication with lorazepam to only patients for whom alternative treatment options are inadequate. PROTECT FROM LIGHT. Dose range: 0.025 to 0.1 mg/kg/dose. Clemastine: (Moderate) Coadministration can potentiate the CNS effects (e.g., increased sedation or respiratory depression) of either agent. If a higher dosage is needed, increase the evening dose before the daytime doses. Monitor patients for decreased pressor effect if these agents are administered concomitantly. Doxylamine; Pyridoxine: (Moderate) Coadministration can potentiate the CNS effects (e.g., increased sedation or respiratory depression) of either agent. Suspensions were extemporaneously prepared at a . If such therapy is initiated or discontinued, monitor the clinical response to the benzodiazepine. Pre-existing depression may emerge or worsen during use of benzodiazepines including lorazepam. Lorazepam Intensol Oral Concentrate, USP, CIV Rx Only - DailyMed Lorazepam is administered orally. If a benzodiazepine is prescribed for an indication other than epilepsy in a patient taking an opiate agonist, use a lower initial dose of the benzodiazepine and titrate to clinical response. Lorazepam dosage should be modified based on clinical response and degree of hepatic impairment; a smaller dosage may be sufficient for patients with severe insufficiency. If benzhydrocodone is initiated in a patient taking a benzodiazepine, reduce initial dosage and titrate to clinical response. The no-effect dose was 1.25 mg/kg/day (approximately 6 times the maximum human therapeutic dose of 10 mg per day). Use caution with this combination. Aspirin, ASA; Caffeine: (Minor) Patients taking benzodiazepines for insomnia should not use caffeine-containing products prior to going to bed as these products may antagonize the sedative effects of the benzodiazepine. How do I store lorazepam? Avoid prescribing opiate cough medications in patients taking benzodiazepines. Educate patients about the risks and symptoms of respiratory depression and sedation. Physical stability of highly concentrated injectable drugs solutions used in intensive care units. Avoid opiate cough medications in patients taking benzodiazepines. The severity and timeline of the withdrawal symptoms will depend largely on who long one has used Lorazepam, the size of the doses taken, the frequency of the doses, concurrent substance use, and the presence . Long-Term Stability of Lorazepam in Sodium Chloride 0.9% Stored at Different Temperatures in Different Containers. Diphenhydramine: (Moderate) Coadministration can potentiate the CNS effects (e.g., increased sedation or respiratory depression) of either agent. Because lorazepam can cause drowsiness and a decreased level of consciousness, there is a higher risk of falls, particularly in the elderly, with the potential for subsequent severe injuries. Electric medication storage boxes are available and for long expeditions are a reasonable solution. Limit the use of opiate pain medications with benzodiazepines to only patients for whom alternative treatment options are inadequate. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. Metyrapone: (Moderate) Metyrapone may cause dizziness and/or drowsiness. Prescribers should re-assess patients for drowsiness or sleepiness regularly throughout treatment, especially since events may occur well after the start of treatment. These interactions are probably pharmacodynamic in nature. Educate patients about the risks and symptoms of respiratory depression and sedation. storage of the drug, lorazepam concentration did not substantially degrade over a 60-day period; lorazepam stored in an oven kept at 37 C experienced signicant degradation, suggesting that lorazepam's stability is heat-sensitive.4 Midazolam is thought to be stable at room temperature, but the heat stability and degrada- For the 1 mg/mL solution, 20 mL of the 2 mg/mL lorazepam preparation and 20 mL of 5% dextrose injection were added to a 250 mL evacuated bottle. The severity of this interaction may be increased when additional CNS depressants are given. Cisapride: (Moderate) Cisapride may enhance the sedative effects of benzodiazepines. Drugs that can cause CNS depression, if used concomitantly with olanzapine, can increase both the frequency and the intensity of adverse effects such as drowsiness, sedation, dizziness, and orthostatic hypotension. Mean kinetic temperature (MKT) exposure was derived for each sample. Ethynodiol Diacetate; Ethinyl Estradiol: (Minor) Ethinyl estradiol may enhance the metabolism of lorazepam. Patient counseling is important, as cisapride alone does not cause drowsiness or affect psychomotor function. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. Avoid lorazepam extended-release capsules and utilize lorazepam immediate-release dosage forms that can be easily titrated. Methyldopa: (Moderate) Methyldopa is associated with sedative effects. Use caution with this combination. Clonidine: (Moderate) Clonidine has CNS depressive effects and can potentiate the actions of other CNS depressants including benzodiazepines. If a benzodiazepine is prescribed for an indication other than epilepsy in a patient taking an opiate agonist, use a lower initial dose of the benzodiazepine and titrate to clinical response. Butalbital; Acetaminophen; Caffeine: (Moderate) Additive CNS and/or respiratory depression may occur with concurrent use. Use these drugs cautiously with MAOIs; warn patients to not drive or perform other hazardous activities until they know how a particular drug combination affects them. If administered to patients who have received a benzodiazepine chronically, abrupt interruption of benzodiazepine agonism by flumazenil can induce benzodiazepine withdrawal including seizures. Metabolic acidosis is associated with the use of dichlorphenamide and has been reported rarely with the use of lorazepam injection for the treatment of status epilepticus. A reduction in dose of the CNS depressant may be needed in some cases. Additive drowsiness and/or dizziness is possible. DISCONTINUATION: To discontinue, gradually taper the dose. PDF Impact of Temperature Exposure on Stability of Drugs in a Real-World Consider alternatives to benzodiazepines for conditions such as anxiety or insomnia in patients receiving buprenorphine maintenance treatment. Initiation of sleep induction or maintenance medication should be preceded or accompanied by non-pharmacologic interventions and maximized treatment of underlying conditions (if applicable). Chlorpheniramine; Dextromethorphan; Phenylephrine: (Moderate) Coadministration can potentiate the CNS effects (e.g., increased sedation or respiratory depression) of either agent. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. In patients treated with buprenorphine for opioid use disorder, cessation of benzodiazepines or other CNS depressants is preferred in most cases. If a benzodiazepine is prescribed for an indication other than epilepsy in a patient taking an opiate agonist, use a lower initial dose of the benzodiazepine and titrate to clinical response. Titrate the dose of remimazolam to the desired clinical response and continuously monitor sedated patients for hypotension, airway obstruction, hypoventilation, apnea, and oxygen desaturation. Limit the use of opiate pain medications with benzodiazepines to only patients for whom alternative treatment options are inadequate. Glecaprevir; Pibrentasvir: (Moderate) Monitor for an increase in lorazepam-related adverse reactions and consider reducing the dose of lorazepam if concomitant use of lorazepam and glecaprevir is necessary. Benzodiazepine dependence can occur after administration of therapeutic doses for as few as 1 to 2 weeks and withdrawal symptoms may be seen after the discontinuation of therapy. Therefore, in the management of overdosage, it should be borne in mind that multiple agents may have been taken. Dosage for patients with severe hepatic disease should be adjusted carefully according to patient response; lower doses may be sufficient in such patients. Lorazepam Macure . to determine the stability of amoxicillin trihydrate- clavulanate If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. Use caution with this combination. Ergotamine; Caffeine: (Minor) Patients taking benzodiazepines for insomnia should not use caffeine-containing products prior to going to bed as these products may antagonize the sedative effects of the benzodiazepine. Lorazepam injection also contains benzyl alcohol as a preservative. Levocetirizine: (Moderate) Concurrent use of cetirizine/levocetirizine with benzodiazepines should generally be avoided. If a benzodiazepine is prescribed for an indication other than epilepsy in a patient taking an opiate agonist, use a lower initial dose of the benzodiazepine and titrate to clinical response. (Moderate) Monitor for an increase in lorazepam-related adverse reactions and consider reducing the dose of lorazepam if concomitant use of lorazepam and paritaprevir is necessary. Avoid use of benzodiazepines in older adults with the following due to the potential for symptom exacerbation or adverse effects: delirium (new-onset or worsening delirium), dementia (adverse CNS effects), and history of falls/fractures (ataxia, impaired psychomotor function, syncope, and additional falls). ASHP Recommended Standard Concentrations for Adult Continuous Infusions: 1 mg/mL. Avoid lorazepam extended-release capsules and utilize lorazepam immediate-release dosage forms that can be easily titrated. Concurrent administration of lorazepam with a UGT inhibitor may result in increased plasma concentrations, reduced clearance, and prolonged half-life of lorazepam. Administer immediately; do not store for future use.Storage: Protect from light. Keywords: Educate patients about the risks and symptoms of respiratory depression and sedation. (PDF) Chemical Stability of Extemporaneously Prepared Lorazepam Drospirenone; Ethinyl Estradiol; Levomefolate: (Minor) Ethinyl estradiol may enhance the metabolism of lorazepam. Use lowest effective dose. Esophageal dilation occurred in rats treated with lorazepam for more than one year at 6 mg/kg/day. the slight difference in stability at room tempera- . Papaverine: (Moderate) Concurrent use of papaverine with potent CNS depressants such as benzodiazepines could lead to enhanced sedation. Budgeting in the post-COVID era: Be in the room where it happens. Codeine; Guaifenesin; Pseudoephedrine: (Major) Concomitant use of opiate agonists with benzodiazepines may cause respiratory depression, hypotension, profound sedation, and death.
