What Happens If You Miss a Dose of Prempro

According to FDA-approved prescribing information for Prempro, if you miss a dose, take it as soon as you remember that day; do not double doses unless directed by your prescriber. If it is almost time for your next dose, skip the missed pill and resume your regular schedule.

Per FDA-approved prescribing information for Prempro, Prempro is a daily, combined estrogen-plus-progestin tablet. Missing a single tablet may allow return of menopausal symptoms such as hot flashes or breakthrough bleeding, particularly in the first few months of therapy. According to FDA-approved prescribing information for Prempro, the progestin component is intended to support the uterine lining; missing occasional doses does not meaningfully alter long-term outcomes, but missing several days in a row may lead to symptom return or may cause irregular bleeding. Contact your prescriber if doses are missed repeatedly or if symptoms change.

What to do if you miss a dose

• If you remember the same day: according to FDA-approved prescribing information for Prempro, take the missed tablet right away and then take the next dose at the usual time.
• If it's nearly time for your next pill: per FDA-approved prescribing information for Prempro, skip the missed dose and take only the next scheduled pill — do not take two tablets at once unless directed by your prescriber.
• If you vomit within two hours of taking a pill: the dose may not have been fully absorbed; consult your prescriber or pharmacist for guidance on whether to take another tablet.
• If you miss two or more consecutive days: per FDA-approved prescribing information for Prempro, resume taking one tablet daily and contact your prescriber for specific advice. Prolonged gaps may cause return of menopausal symptoms and may increase the chance of irregular or heavy bleeding.
• When to contact your clinician: per FDA-approved prescribing information for Prempro, the FDA labeling describes heavy vaginal bleeding, severe abdominal pain, sudden chest pain, shortness of breath, and swelling or redness in a leg as serious events associated with estrogen-containing products — including cardiovascular events, deep vein thrombosis (DVT), pulmonary embolism (PE), endometrial cancer, breast cancer, and probable dementia in women 65 and older; 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.
• Long-term effect: occasional missed doses may alter the overall balance of risks and benefits of HRT. Persistent nonadherence or stopping for extended periods may reduce symptom control and may reduce any bone-protective effects. Contact your prescriber to discuss whether your current regimen remains appropriate.
