ESTRING key facts
What is ESTRING?
ESTRING is the brand name for estradiol and is available as a vaginal ring.
What dosages is ESTRING available in?
ESTRING is available as a vaginal ring that releases estradiol, approximately 7.5 mcg per 24 hours, in a consistent stable manner over 90 days.
What is ESTRING used for?
ESTRING is an estrogen replacement and is used to treat vaginal dryness, burning, and irritation due to menopause.
How does ESTRING work?
ESTRING is an estrogen replacement that slowly releases a steady amount of estrogen to your vagina over 3 months. Your body makes a lot less estrogen during menopause, which can cause thinning of your vaginal walls. This can lead symptoms, such as vaginal dryness, burning, and irritation. Replacing estrogen helps relieve these menopausal symptoms.
How do I take ESTRING?
ESTRING is dosed as 1 ring inserted into your vagina as far as it can comfortably go. Remove and insert a new ring every 3 months.

If you have Medicare Part D or Medicare Advantage and none of the ESTRING savings options are applicable or affordable for me, what can you do?
If you are insured with Medicare and the ESTRING drug savings options are not applicable to you and still remain unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and after you have selected your state, it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
People who qualify for both Medicare and Medicaid are called ‘dual eligibles’.
If you are denied Medicaid for ESTRING, and you are still unable to afford your copay or co-insurance element (for example if you are in the coverage gap or Donut Hole) then you may be eligible for a federal support program like Low Income Subsidy. To be eligible for Low Income Subsidy, you need to be a resident in one of the 50 States or the District of Columbia. You can check eligibility online at SSA Medicare D Extra Help. You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).
I am uninsured or underinsured and none of the ESTRING prescription saving options are applicable or affordable for me, what can I do?
If you are uninsured or underinsured (for example, ESTRING is not covered by your plan) and the drug savings options are not applicable or still unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
If you are denied and all else fails, and if you have been prescribed ESTRING for an FDA-approved indication, you can call the pharmaceutical company to see if they have any other assistance programs.
I am commercially or privately insured and none of the ESTRING prescription saving options are applicable or affordable for me, what can I do?
If your medication is not covered by your plan, you can you can appeal your insurance company’s decision. Sometimes, a formal appeal can result in the drug being covered if it is deemed medically necessary.
