For many years now the most common concentration of oral morphine solution used in hospice has been 20 mg per mL. Although the concentration is exactly the same, you may begin seeing different labeling. It may now read 100 mg per 5 mL.
The Food and Drug Administration worked with Roxane, the largest manufacturer of oral morphine solution to change the labeling and the look of the product to reduce the possibility of errors. The intent of this labeling is to help differentiate this product from another product with a concentration of 20 mg per 5 mL.
The volume of liquid is unchanged:
- 5 mg = 0.25 mL
- 10 mg = 0.5 mL
- 20 mg = 1 mL
The new labeling may mean a little change in our mathematics, but remember that the concentration has not changed.
If you have any questions about the concentration or labeling, call Pathways (1.888.755.7855) and we will be glad to double check your calculations with you.
