Estring is used after menopause to treat moderate to severe menopausal changes in and around the vaginal area such as as dryness, burning, and itching of the vaginal area, urgency or irritation with urination, and pain during sexual intercourse).

Estring is an off-white, soft, flexible ring with a center that contains 2 mg of estradiol. The ring releases estradiol into the vagina in a consistent, stable manner for 90 days. It should be removed after 90 days of continuous use. If continued therapy is required, the ring should be replaced.

How to use Estring Vaginal Ring

Use Estring exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

Wash your hands before and after inserting an Estring vaginal ring.

To use the Estring vaginal ring:

Squeeze the sides of the Estring vaginal ring together and insert it into the vagina as far as possible (into the upper 1/3 of the vagina). You should not be able to feel the ring once it is in position. If you can feel it, use a finger to push it further into the vagina. It is not possible for the ring to go too far in or become lost.

The Estring vaginal ring should remain in place for 90 days. It should then be removed and replaced by a new ring, if prescribed by your doctor. If at any time the ring falls out, rinse it with warm water and reinsert it. If it slides down into the lower part of the vagina, use a finger to reinsert it.

The Estring vaginal ring does not need to be removed during sexual intercourse. It should not be felt by either partner. If it is bothersome, it can be removed, rinsed with warm water, and reinserted following intercourse.

To remove the ring, loop a finger through the ring and gently pull it from the vagina.

Your doctor should check your progress on a regular basis to determine whether you should continue this treatment. Self-examine your breasts for lumps on a monthly basis and have a mammogram every year while using Estring.

If you need major surgery or will be on long-term bed rest, you may need to stop using this medicine for a short time. Any doctor or surgeon who treats you should know that you are using Estring.

Store at room temperature away from moisture and heat. Keep the Estring vaginal ring in its protective pouch until you are ready to use it.
