Use in Patients with Renal Impairment No clinical studies were conducted to evaluate the effect of renal impairment on the pharmacokinetics of mesna injection.

Use in Patients with Hepatic Impairment No clinical studies were conducted to evaluate the effect of hepatic impairment on the pharmacokinetics of mesna injection.

Preparation for Intravenous Administration and Stability Preparation Determine the volume of mesna injection for the intended dose. Dilute the volume of mesna injection for the dose in any of the following fluids to obtain a final concentration of 20 mg/mL: 5% Dextrose Injection, USP 5% Dextrose and 0.2% Sodium Chloride Injection, USP 5% Dextrose and 0.33% Sodium Chloride Injection, USP 5% Dextrose and 0.45% Sodium Chloride Injection, USP 0.9% Sodium Chloride Injection, USP Lactated Ringer’s Injection, USP Stability The mesna injection multidose vials may be stored and used for up to 8 days after initial puncture.

Store diluted solutions at 25°C (77°F). Use diluted solutions within 24 hours. Do not mix mesna injection with epirubicin, cyclophosphamide, cisplatin, carboplatin, and nitrogen mustard. The benzyl alcohol contained in mesna injection vials can reduce the stability of ifosfamide. Ifosfamide and mesna injection may be mixed in the same bag provided the final concentration of ifosfamide does not exceed 50 mg/mL.

Higher concentrations of ifosfamide may not be compatible with mesna injection and may reduce the stability of ifosfamide. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Any solutions which are discolored, hazy, or contain visible particulate matter should not be used.
