Each MILPROSA (progesterone) vaginal system is a white to off-white, flexible, non-biodegradable silicone ring (toroidal-shaped), which contains 1.78 grams of progesterone and releases an average of 11 mg/day of progesterone over a 7-day period of use. MILPROSA vaginal system has an inner and outer diameter of approximately 38 mm and 55 mm, respectively, and a cross-sectional diameter of approximately 8.5 mm.

Each MILPROSA is packed individually in a sealed foil pouch. These pouches are available in cartons packed:

  • 2 vaginal systems per carton (NDC 55566-9400-1)

Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [See USP Controlled Room Temperature]. Do not refrigerate or freeze and avoid excessive heat.

After use, place in pouch and discard via a drug take-back option if available; otherwise, mix with something undesirable, such as used coffee grounds, dirt, or cat litter to make it less appealing to children and pets. Place the mixture in something that can be closed (a re-sealable zipper storage bag, empty can, or other container) and discard in the household trash. DO NOT flush down toilet. See drug disposal information at www.fda.gov/drugdisposal for more information.


Advise the patient to read the FDA-approved patient labeling (Instructions for Use).

  • MILPROSA is not recommended for use with other vaginal products (such as antifungal products, vaginal lubricants, diaphragms, and condoms) as this concomitant use has not been studied and may alter the progesterone release and absorption from the vaginal system [see Warnings and Precautions (5.4) and Drug Interactions (7)].
