Dosing in kidney impairment
This label has no separate kidney-impairment dosing section. Check warnings and clinical pharmacology in the full label.
Dosing in liver impairment
Hepatic Impairment In patients with severe hepatic impairment, the dose of BYFAVO should be carefully titrated to effect. Depending on the overall status of the patient, lower frequency of supplemental doses may be needed to achieve the level of sedation required for the procedure. All patients should be monitored for sedation-related cardiorespiratory complications [see Clinical Pharmacology ] .

Important Dosage and Administration Instructions BYFAVO can depress respiration. Continuously monitor patients for early signs of hypoventilation, airway obstruction, and apnea using capnography, pulse oximetry, and clinical assessment. Only personnel trained in the administration of procedural sedation, and not involved in the conduct of the diagnostic or therapeutic procedure, should administer BYFAVO.
Administering personnel must be trained in the detection and management of airway obstruction, hypoventilation, and apnea, including the maintenance of a patent airway, supportive ventilation, and cardiovascular resuscitation. Supplemental oxygen, resuscitative drugs, and age- and size-appropriate equipment for bag/valve/mask assisted ventilation must be immediately available during administration of BYFAVO.
A benzodiazepine reversal agent should be immediately available. Continuously monitor vital signs during sedation and through the recovery period [see Warnings and Precautions ] . Peak sedation occurs approximately 3 to 3.5 minutes after an initial 5 mg intravenous injection of BYFAVO given over a 1-minute period [see Clinical Pharmacology ].
Titrate subsequent doses of BYFAVO on the basis of clinical judgment and assessment of the depth of sedation. If maintenance of procedural sedation is inadequate, consider alternative medications [see Clinical Studies ] .
Preparation Reconstitution of BYFAVO (remimazolam) for injection Strict aseptic technique must be maintained during handling of BYFAVO. This product does not contain preservative. Once removed from packaging, protect vials from light. Each single-patient-use vial contains 20 mg BYFAVO lyophilized powder for reconstitution.
The product must be prepared immediately before use. To reconstitute, add 8.2 mL sterile 0.9% Sodium Chloride Injection, USP, to the vial, directing the stream of solution toward the wall of the vial. Gently swirl the vial (do not shake) until the contents are fully dissolved. The reconstituted product will deliver a final concentration of 2.5 mg/mL solution of BYFAVO.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Upon reconstitution, the solution should be a clear, colorless to pale yellow solution. Discard if particulate matter or discoloration is observed. If not used immediately, reconstituted BYFAVO may be stored in the vial for up to 8 hours under controlled room temperature at 20°C to 25°C (68°F to 77°F).
After 8 hours, any unused portion must be discarded.
Administration with Other Fluids BYFAVO has been shown to be compatible with the following intravenous fluids: 0.9% Sodium Chloride Injection, USP 5% Dextrose Injection, USP 20% Dextrose Injection, USP 5% Dextrose and 0.45% Sodium Chloride Injection, USP. BYFAVO has also been shown to be compatible with Ringer's Solution, a solution containing Sodium Chloride, Potassium Chloride and Calcium Chloride Dihydrate.
BYFAVO has been shown to be incompatible with the following intravenous fluids: Lactated Ringer's Solution, a solution containing Sodium Chloride, Sodium Lactate, Potassium Chloride, and Calcium Chloride Dihydrate. Lactated Ringer's Solution is also known as Ringer's Lactate Solution, Compound Sodium Lactate Solution, and Hartmann's Solution.
Acetated Ringer's Solution, a solution containing Sodium Chloride, Sodium Acetate, Potassium Chloride, and Calcium Chloride Dihydrate. BYFAVO compatibility with other agents has not been adequately evaluated. Do not mix BYFAVO with other drugs or fluids prior to administration.

7 DRUG INTERACTIONS
7.1 Opioid Analgesics and Other Sedative-Hypnotics The sedative effect of intravenous BYFAVO can be accentuated by concomitantly administered CNS depressant medications, including opioid analgesics, other benzodiazepines, and propofol. Continuously monitor vital signs during sedation and through the recovery period. Titrate the dose of BYFAVO when administered with opioid analgesics and sedative-hypnotics to the desired clinical response [see Warnings and Precautions (5.2) ].
Contraindications
4 CONTRAINDICATIONS BYFAVO is contraindicated in patients with a history of severe hypersensitivity reaction to dextran 40 or products containing dextran 40 [see Warnings and Precautions (5.3) ]. Hypersensitivity to dextran 40. ( 4 )
Safety data

Liver injury (LiverTox)
ELikelihood score E: Unlikely cause of clinically apparent liver injury.
Remimazolam is an ultra-short acting benzodiazepine used intravenously for induction and maintenance of sedation for adults undergoing short term procedures not requiring general anesthesia. Remimazolam sedation has not been associated with serum aminotransferase elevations and has not been linked to cases of clinically apparent liver injury.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Neonates born to mothers using benzodiazepines late in pregnancy have been reported to experience symptoms of sedation and/or neonatal withdrawal [see Warnings and Precautions (5.4) , Clinical Considerations ]. Available data from published observational studies of pregnant women exposed to benzodiazepines do not report a clear association with benzodiazepines and major birth defects (see Data ). In animal studies, reduced fetal weights but no evidence of malformations or embryofetal lethality were noted in a study in which pregnant rabbits were treated intravenously with 4 times the maximum recommended human dose (MRHD) of 30 mg during organogenesis.
Adequate rodent reproductive and developmental toxicology studies have not been completed to fully evaluate the effects of BYFAVO. Published studies in pregnant primates demonstrate that the administration of anesthetic and sedation drugs that block NMDA receptors and/or potentiate GABA activity during the period of peak brain development increases neuronal apoptosis in the developing brain of the offspring when used for longer than 3 hours. There are no data on pregnancy exposures in primates corresponding to periods prior to the third trimester in humans (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Benzodiazepines cross the placenta and may produce respiratory depression, hypotonia, and sedation in neonates. Monitor neonates exposed to BYFAVO during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to BYFAVO during pregnancy for signs of withdrawal.
Manage these neonates accordingly [see Warnings and Precautions (5.4) ]. Data Human Data Published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. Although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted. In addition, the majority of more recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol,…
Breastfeeding (LactMed)
Although the manufacturer recommends that nursing mothers pump and discard breast milk for 5 hours after a dose, anesthesia guidelines recommend that breastfeeding can resume as soon as the mother has recovered sufficiently from general anesthesia to nurse. This strategy was employed at one center with no infant sedation or adverse effects. When a combination of anesthetic agents is used for a procedure, follow the recommendations for the most problematic medication used during the procedure.
