The structural formula is: Each metered-dose pump contains 8.1 mL and is designed to deliver 56 sprays of 90 mcL each after priming. One spray of Evamist contains 1.53 mg estradiol. The metered-dose pump should be held upright and vertical for spraying. Before a new applicator is used for the first time, the pump should be primed by spraying 5 times with the cover on.
