When Estring Vaginal Ring Should Not Be Used:

Do not use Estring Vaginal Ring if you have unusual vaginal bleeding that has not been checked by a doctor. You should not use Estring Vaginal Ring if you have had blood clots (such as deep vein thrombosis or pulmonary embolism), liver disease, or if you have had a stroke or heart attack in the past 12 months.

How to Use Estring Vaginal Ring:
Cream, Insert, Suppository
- Your doctor will tell you how much of Estring Vaginal Ring to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
- Estring Vaginal Ring comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
- Wash your hands with soap and water before and after using Estring Vaginal Ring or inserting the ring.
-
To use the vaginal ring:
- Estring Vaginal Ring is contained in a ring that you or your health caregiver will put into your vagina. The ring will slowly release small amounts of medicine for your body to absorb. Your health caregiver will show you how to insert the ring.
- Leave the ring in its sealed wrapper until you are ready to use it.
- Once the ring is in place in your vagina, you should not be able to feel the ring. If you feel uncomfortable, the ring may not be pushed in far enough. Gently push the ring farther into your vagina. If you feel pain, talk to your doctor.
- You will leave the ring in for 90 days (3 months), unless your doctor tells you a different schedule. After that time, remove the ring and insert a new one. If you forget to remove the ring after 90 days, call your doctor for instructions.
- The ring may move down into the lower part of your vagina accidently. One thing that could make this happen is straining to have a bowel movement. Use your finger to gently push the ring back into place. If the ring comes all the way out of your vagina, rinse it off with warm water and put it back in. Call your doctor if the ring comes out several times.
- If you need to remove the ring, hook your finger through the ring and pull it out.
-
To use the vaginal tablet:
- The tablet should be used only in your vagina. Do not swallow the tablet.
- Each vaginal tablet comes packaged inside an applicator. Do not take the tablet out of the applicator. If the tablet comes out of the applicator before you put it in your vagina, do not use the tablet or applicator. Use a new applicator that still has the tablet inside it.
- Take the applicator out of the plastic wrap before using it.
- Use the applicator only one time and then throw it away. Use a new applicator for each dose.
- It is best to always use Estring Vaginal Ring at the same time of day. Most women will start by inserting a new tablet every day for two weeks, then change to inserting a new tablet only 2 days each week. Carefully follow the schedule that your health caregiver tells you to.
-
To use the vaginal cream:
- This cream medicine comes in a tube with a plastic applicator. You will need to use the applicator each time you use the medicine, so wash the applicator with warm, soapy water after each use. Do not use the medicine without the applicator.
- Measure the cream using the marks on the plastic applicator. Make sure you use the correct mark for your specific dose.
How to Store and Dispose of Estring Vaginal Ring:
- Store the unopened packages of Estring Vaginal Ring at room temperature, away from heat, moisture, and direct light.
- Wrap the used vaginal ring in tissue and throw it away where children and pets cannot get to it. Do not flush the ring down the toilet.
- Ask your pharmacist, doctor, or health caregiver about the best way to dispose of the used medicine applicator(s), containers and any leftover medicine after you have finished your treatment. You will also need to throw away old medicine after the expiration date has passed.
- Keep all medicine away from children and never share your medicine with anyone.
