The stability of this product when prepared in DMSO has not been determined. In general, solutions in DMSO should be prepared fresh and used promptly. Epinephrine is most stable in acidic aqueous solutions at pH 3.6, when stored tightly sealed under nitrogen or argon. Solutions prepared in basic buffers are unstable and turn red in color due to degradation. Published literature indicates solutions are stable for at least 1 month when stored at 4°C or 25°C. Commercial solutions are often assigned a shelf life of greater than 1 year.
