Retatrutide Reconstitution to 4 mg/mL

Retatrutide concentration after reconstitution is calculated as total retatrutide amount (mg) divided by final diluent volume (mL). [1] A 36 mg vial reconstituted to a concentration of 4 mg/mL requires a final volume of 9 mL. [1]

Calculation of Final Volume

  • Desired concentration = 4 mg/mL. [1]
  • Total retatrutide amount = 36 mg. [1]
  • Final volume required = 36 mg ÷ 4 mg/mL = 9 mL. [1]

Diluent Amount to Add

  • 9 mL of Sterile Water for Injection should be added to the vial to obtain 4 mg/mL (36 mg ÷ 9 mL = 4 mg/mL). [1]

Preparation Method Consistent With Label Instructions

  • Sterile Water for Injection should be withdrawn using aseptic technique into a sterile syringe. [1]
  • The diluent should be injected into the vial containing the lyophilized powder. [1]
  • The vial should be gently swirled until the powder fully dissolves. [1]
  • Shaking vigorously should be avoided. [1]
  • The solution should be clear. [1]

Concentration Check After Reconstitution

  • The expected concentration after reconstitution is 4 mg/mL. [1]
  • A test draw of 1 mL should contain 4 mg total retatrutide. [1]

Storage and Use Considerations

  • Reconstitution should be performed with sterile technique and the reconstituted solution should be handled according to label directions. [1]
  • Use should be restricted to under medical supervision. [1]

Medication Safety Considerations

  • Retatrutide should not be used outside medical supervision. [1]
  • Guidance should be followed regarding dose titration and monitoring for adverse effects. [1]
