How to take Eluryng

  • A healthcare provider will demonstrate how to put in the ring. 

  • Please read the Patient Information sheet and Instructions for Use included with the ring.

  • Each EluRyng box contains three vaginal rings, enough for three months. These rings can be stored at room temperature (68-77°F) for up to four months.

    • Do not store it in temperatures exceeding 86˚F.

    • Avoid direct sunlight.

  • If backup barrier birth control is necessary, do not use female barrier methods such as a diaphragm, cervical cap, or female condom.

How to start:

  • When first starting EluRyng, you can insert the ring:

    • On day one of the menstrual cycle, barrier birth control is not necessary.

    • On days two to five of the menstrual cycle, use barrier birth control for seven days.

  • Women on birth control pills can start EluRyng and quit taking pills at any time.

    • If the pills run out, EluRyng must be inserted the day after the last pill is taken.

  • Ask the prescriber when to start EluRyng if you:

    • Are using a progestin-only mini-pill, implant, IUD, or injectable contraceptive

    • Have had a recent abortion or miscarriage

    • Have given birth

  • Use backup barrier birth control for seven days after switching from progestin-only birth control.

  • Twenty-one days after insertion, remove the ring on the same day at the same time it was inserted. 

  • The next ring must be inserted on the same day of the week, exactly seven days after removal.

Insertion:

  • Wash and dry your hands.

  • Choose a comfortable position (sitting, standing, or lying down)

  • Remove the ring from the pouch.

  • Squeeze the sides of the ring together. 

  • Insert the ring into the vagina.

  • Use your index finger to push the ring deeper into the vagina.

  • There is no correct position for the ring. It works anywhere inside the vagina.

  • Once the ring is in place, most women don’t feel it. 

    • If the ring is uncomfortable, it may not be inserted far enough. With your index finger, gently push the ring farther into your vagina. 

    • If it’s painful, the ring may have been accidentally inserted into the bladder. Check to see if the ring is in the vagina. If not, call a healthcare provider immediately.

  • Regularly check to make sure the ring is still in the vagina. 

Removal:

  • Wash and dry your hands.

  • Insert a finger into the vagina and hook it through the EluRyng. 

  • Gently pull it from the vagina.

  • Put the used ring back in its resealable pouch and dispose of it in a trash can.

What to do if you miss a dose of Eluryng

  • A missed dose is considered:

    • Forgetting to insert a new ring at the beginning of the cycle

    • Forgetting to remove the old ring

    • When the ring comes out

If you forget to insert a new ring:

  • Check for pregnancy.

  • If you are not pregnant, insert the new ring and use backup barrier birth control for seven days.

If you forget to remove an old ring:

  • If it’s less than four weeks (28 days) after the ring was first inserted, remove it, allow seven days to pass, and insert a new one.

  • If it’s more than four weeks, check for pregnancy. If you are not pregnant, insert a new ring and use backup barrier birth control for seven days.

If a ring slips out of the vagina:

  • If it’s broken:

    • Throw it away and insert a new ring.

  • If it’s not broken and has been out of the vagina for less than three hours:

    • Rinse the ring with cool or lukewarm water and reinsert it.

  • If it’s been out of the vagina for more than three hours:

    • In weeks one and two, reinsert the ring. Use backup barrier birth control for seven days.

    • In week three, throw out the ring. Either insert a new ring and restart the 21-day cycle or wait seven days and insert a new ring to restart the 21-day cycle. Either way, use backup barrier birth control for seven days after the new ring is inserted.
