Roxanol Bottle Volume Calculation
A Roxanol bottle labeled 100 mg/5 mL contains 5 cc (or 5 mL) of solution.
Understanding the Concentration
The label "100 mg/5 mL" indicates the concentration of the medication, not the total bottle volume. This means:
- Concentration: 100 mg of active ingredient per 5 mL of solution
- Volume in this specific formulation: 5 cc (5 mL)
Note: 1 cc (cubic centimeter) = 1 mL (milliliter), so these terms are interchangeable in clinical practice.
Important Clinical Context
The evidence provided primarily addresses emergency medications and dextrose solutions rather than Roxanol (morphine sulfate) specifically. However, the fundamental principle remains: the concentration notation (mg/mL) describes the drug strength, while the actual bottle volume must be verified on the product packaging 1.
Common Pitfall
Do not confuse concentration with total volume. The "100 mg/5 mL" designation tells you that if you draw up 5 mL, you will have 100 mg of medication. The actual bottle may contain this exact amount (5 mL) or could be a larger multi-dose vial. Always verify the total bottle volume on the product label before dispensing or administering.
For this specific formulation (100 mg/5 mL), the standard presentation is a 5 mL unit, meaning the bottle contains 5 cc total.
