2.4 Preparation and

Storage of Solutions of Vancomycin Hydrochloride Each vancomycin hydrochloride for oral solution kit contains 1 bottle of vancomycin hydrochloride USP powder and 1 bottle of pre‑measured Grape‑Flavored Diluent to be added to the vancomycin bottle. A healthcare provider (i.e., a pharmacist) must reconstitute vancomycin hydrochloride USP powder with the Grape‑Flavored Diluent provided in the kit. Vancomycin hydrochloride for oral solution is available in various strengths and volumes in the kit as shown in Table 1.

Table 1: Vancomycin Concentration and Volume after Reconstitution Vancomycin Concentration after Reconstitution Final Volume of Vancomycin Hydrochloride after Reconstitution Vancomycin Strength per Bottle Diluent for Vancomycin Hydrochloride 25 mg/mL 150 mL 3.75 g 147 mL 300 mL 7.5 g 295 mL 50 mg/mL 150 mL 7.5 g 145 mL 300 mL 15.0 g 289 mL Steps for the Preparation of Solutions of Vancomycin Hydrochloride Hold the neck of the bottle containing the vancomycin hydrochloride USP powder for oral solution (see Table 1 ), and tap the bottom edges on a hard surface to loosen the powder. Remove the cap from the vancomycin hydrochloride USP powder for oral solution bottle (“Powder Bottle”). Tap the top of the induction seal liner to loosen any powder that may have adhered to the liner. Carefully and slowly peel back the inner foil seal liner from the Powder Bottle. Shake the Grape‑Flavored Diluent (see ) for a few seconds. Remove the cap from the diluent bottle. Carefully and slowly peel back the inner foil seal from the diluent bottle. Transfer approximately one-half the contents of Grape-Flavored Diluent into the Powder Bottle. Replace the Powder Bottle cap, tighten onto the Powder Bottle, and shake the Powder Bottle vertically for approximately 45 seconds.

NOTE: DO NOT use the diluent cap on the Powder Bottle as it may cause the solution to leak from the bottle. Re-open the Powder Bottle and add the remaining Grape‑Flavored Diluent into the Powder Bottle. Replace the Powder Bottle cap, tighten onto the Powder Bottle, and shake the Powder Bottle for approximately 30 seconds.

NOTE: DO NOT use the diluent cap on the Powder Bottle as it may cause the solution to leak from the bottle. Dispense the Powder Bottle containing reconstituted solution of vancomycin hydrochloride oral solution to the patient. Instruct the patient to shake the reconstituted solution of vancomycin hydrochloride well before each use and to use an oral dosing device that measures the appropriate volume of the oral solution in milliliters. Store the reconstituted solution of vancomycin hydrochloride at refrigerated conditions, 2°C to 8°C (36°F to 46°F) when not in use. Discard the reconstituted solution of vancomycin hydrochloride after 14 days, or if it appears hazy or contains particulates.
