What Happens If You Miss a Dose of Femring

If your Femring falls out or you forget to replace it, according to FDA-approved prescribing information for Femring, reinsert it as soon as you remember. If it has been out or unreplaced for more than about 48 hours, insert a new ring and contact your prescriber for specific advice—a gap of this length may allow return of hot flashes and may affect endometrial safety if you still have a uterus.

What to do and why it matters

According to FDA-approved prescribing information for Femring, the appropriate steps depend on the situation:

• Ring still in place but past the 90‑day date: per FDA-approved prescribing information for Femring, replace it with a new ring as soon as you can. A short delay of a few days may allow symptoms to return, as the ring releases decreasing amounts of hormone over time.
• Ring fell out and has been out less than 48 hours: per FDA-approved prescribing information for Femring, rinse with lukewarm water and reinsert the same ring right away. This may restore hormone levels and may help maintain symptom control.
• Ring fell out or was missing 48 hours or more: per FDA-approved prescribing information for Femring, insert a new Femring and contact your clinician. Gaps of this length may reduce symptom relief and may require adjustment of any added progestin schedule (see below).
• You have a uterus: systemic estrogen (Femring) is typically prescribed with a progestin to support the uterine lining. If a missed ring changes the timing of your progestin, contact your prescriber—repeated or prolonged gaps may increase the likelihood of abnormal uterine bleeding or may lead to endometrial changes over time.
• Serious symptoms after a missed dose: per FDA-approved prescribing information for Femring, the FDA labeling describes symptoms such as heavy bleeding, severe pelvic pain, chest pain, shortness of breath, leg swelling or pain, and vision changes as serious events associated with estrogen-containing products, including cardiovascular events, deep vein thrombosis (DVT), pulmonary embolism (PE), endometrial cancer, breast cancer, and, in women aged 65 and older, probable dementia. Patients who experience any of these symptoms should contact their prescriber promptly. Whether any individual symptom warrants intervention depends on personal health factors that a clinician must assess, and published guidance from NAMS or ACOG informs how prescribers evaluate them.

Do not insert an additional ring to make up for a missed one unless directed by your prescriber. If you are ever unsure, contact your clinic. The primary concerns with a missed Femring are return of menopausal symptoms and, for patients with a uterus, maintaining the estrogen–progestin plan on a safe timetable. Contact your prescriber if doses are missed repeatedly or if symptoms change, particularly any new or unusual bleeding.
