Studies in healthy volunteers show that in single high doses, lorazepam has a tranquilizing action on the central nervous system with usually no appreciable effect on the respiratory or cardiovascular systems. At steady state, AUCTau, Cmax, and Cmin were 694 ng x hour/mL, 35 ng/mL and 25 ng/mL, respectively, following once daily administration of the 3 mg ER capsules. Guanfacine: (Moderate) Guanfacine has been associated with sedative effects and can potentiate the actions of other CNS depressants including benzodiazepines. [3], A study evaluated lorazepam 2 mg/mL injectable solutions in clear glass syringes under refrigeration (4-10 C), at ambient temperatures (15-30 C), and at oven-heated temperatures (38 C) for up to 210 days (see Table 2).

Levonorgestrel; Ethinyl Estradiol; Ferrous Bisglycinate: (Minor) Ethinyl estradiol may enhance the metabolism of lorazepam. This action may be additive with other agents that can cause hypotension such as benzodiazepines. 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. The benzodiazepine antagonist flumazenil may be used in hospitalized patients as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. Loxapine: (Moderate) The combination of loxapine and lorazepam has been associated with acute respiratory depression, stupor, and/or hypotension in several patients. As with other benzodiazepines, lorazepam causes CNS depression that may lead to respiratory effects and should be used with extreme caution in patients with significant pulmonary disease such as respiratory insufficiency resulting from chronic lung disease (CLD), chronic obstructive pulmonary disease (COPD) or sleep apnea. Administer immediately; do not store for future use.Storage: Protect from light. Belladonna; Opium: (Major) Concomitant use of opiate agonists with benzodiazepines may cause respiratory depression, hypotension, profound sedation, and death. Limited published data are available in the pediatric population. 10 Equilibrate to room temperature before use. Lofexidine can potentiate the effects of CNS depressants such as benzodiazepines. to determine the stability of amoxicillin trihydrate- clavulanate Brimonidine; Timolol: (Moderate) Based on the sedative effects of brimonidine in individual patients, brimonidine administration has potential to enhance the CNS depressants effects of the anxiolytics, sedatives, and hypnotics including benzodiazepines. Brexanolone: (Moderate) Concomitant use of brexanolone with CNS depressants like the benzodiazepines may increase the likelihood or severity of adverse reactions related to sedation and additive CNS depression. The Beers Criteria are not meant to apply to patients at the end of life or receiving palliative care, when risk-benefit considerations of drug therapy can be different. Avoid lorazepam extended-release capsules and utilize lorazepam immediate-release dosage forms that can be easily titrated. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. In vitro data predicts inhibition of UGT2B7 by cannabidiol, potentially resulting in clinically significant interactions.

Limit the use of mixed opiate agonists/antagonists with benzodiazepines to only patients for whom alternative treatment options are inadequate. Lorazepam is an UGT substrate and paritaprevir is an UGT inhibitor. Patients taking medications such as tricyclic antidepressants, lithium, MAOIs, skeletal muscle relaxants, SSRIs and serotonin norepinephrine reuptake inhibitors (e.g., duloxetine, venlafaxine) should discuss the use of herbal supplements with their health care professional prior to consuming valerian; combinations should be approached with caution in the absence of clinical data. Initially, use a low dosage (i.e., 1 to 2 mg PO) and titrate slowly in the geriatric patient. Increase gradually as needed and tolerated. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. 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. The federal Omnibus Budget Reconciliation Act (OBRA) regulates the use of sedative/hypnotics in long-term care facility (LTCF) residents.

Off-label information indicates stable when maintained at room temperature for up to 6 months. Use caution with this combination. Educate patients about the risks and symptoms of respiratory depression and sedation. Ethinyl Estradiol: (Minor) Ethinyl estradiol may enhance the metabolism of lorazepam. Repeated or lengthy use of general anesthetic and sedation drugs during surgeries or procedures during the third trimester of pregnancy may have negative effects on fetal brain development. Therefore, these patients should be monitored frequently and have their dosage adjusted carefully according to patient response; the initial dosage should not exceed 2 mg. Paradoxical reactions have been occasionally reported during benzodiazepine use.

The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. There is a possibility of interaction with valerian at normal prescription dosages of anxiolytics, sedatives, and hypnotics (including barbiturates and benzodiazepines). Newer evidence suggests that 1 mg/mL solutions may be stored at room temperature for 3 days or under refrigeration for 5 days in a vial or syringe. Immediately after the preparation (hour 0) and after 1, 4, 8, 24, and 48 hours, 2 mL of each solution were withdrawn from each syringe and placed in glass tubes to proceed with the stability test. For these, standard refrigeration is not appropriate. Patients should be advised that if they become pregnant, they should communicate with their physician about the desirability of discontinuing the drug.
