If NuvaRing is out for less than three continuous hours:
If your NuvaRing accidentally falls out, never fear. If it has been out less than three hours, you should still be protected against an unintended pregnancy. Simply rinse the NuvaRing (that has slipped out) with cool-to-lukewarm water (not hot). Then, reinsert it as soon as possible, making certain that it has been reinserted within three hours of falling out. If you have lost the NuvaRing, you can insert a new contraceptive ring – just make sure to stay on the same schedule you would have followed if you were still using the lost ring.
If NuvaRing is out for more than three continuous hours:
- Insert a new NuvaRing immediately which will start your next three-week use period. If you choose this option, you may not experience a period from your previous cycle, yet breakthrough spotting or bleeding may occur.
- Wait for your period to occur and then insert a new contraceptive ring no later than seven days from the time the previous NuvaRing was removed or fell out. This option should only be chosen if the ring was used continuously for the preceding seven days. Additionally, for greatest effectiveness, you should also use a barrier method (like condoms or spermicides) until the new ring has been used continuously for seven days.
- The ring does not stay in the vagina for 3 weeks in a row
- If the ring is left in the vagina for more than 3 weeks
- The ring slides out of the vagina and is not replaced within 3 hours
- The unopened NuvaRing package is exposed to direct sunlight or very high temperatures.
- You use certain medications that can decrease the effectiveness of hormonal contraceptives like the ring.
Although the NuvaRing is 92% to 99.7% effective (with perfect use, less than 1 out of every 100 women who use the ring will become pregnant in one year whereas with typical use, 8 out of every 100 women who use the patch will become pregnant in one year), the effectiveness of the NuvaRing can be lowered due to user error.
