How should I use Annovera?
Use Annovera exactly as directed by your health care professional. Follow all directions on your prescription label and read all medication guides or instruction sheets.
The Annovera vaginal ring will not prevent pregnancy if you wear it only during intercourse. You must wear the ring around-the-clock for 3 full weeks (21 days).
After 21 days, remove the ring and wait 7 full days before inserting the ring again. Try to stay on your schedule of inserting and removing the ring.
Do not leave the Annovera ring out of the vagina for longer than a total of 2 hours during the 21-day wearing time.
If a ring falls out, wash it with mild soap and warm water, pat dry with a clean cloth, and reinsert it.
You may need to use back-up birth control (condoms or spermicide, but not a female condom) for 7 days in a row:
- if the ring has been out of the vagina for more than a total of 2 hours during the 21-day wearing time;
- if the Annovera ring has been out of the vagina for longer than 7 days; or
- if you recently had a baby and have not yet started having periods again.
You may have breakthrough bleeding. Tell your doctor if this bleeding continues for longer than 7 days or is very heavy.
If you need major surgery or will be on long-term bed rest, you may need to stop using Annovera for a short time. Any doctor or surgeon who treats you should know that you are using the Annovera vaginal ring.
Annovera will not protect you from sexually transmitted diseases--including HIV and AIDS. Using a condom can help protect you from these diseases.
Whenever the ring is out of the vagina, wash the ring with mild soap and warm water, pat dry, and store in the case provided. Store at room temperature. Protect from heat, sunlight, and freezing. Follow the provided instructions for cleaning the Annovera vaginal ring when not in use.
After using a Annovera vaginal ring for 1 year, dispose of the used vaginal ring in the case or pouch it came in and throw it away where children and pets cannot get to it. Do not flush the ring down a toilet.
