What Happens If You Miss a Dose of Delestrogen

Missed Delestrogen Dose — What to Do

If you miss a Delestrogen injection, you may notice return of hot flashes, night sweats, mood changes, or vaginal dryness as your blood estrogen falls. According to FDA-approved prescribing information for Delestrogen, you should not inject extra doses to make up for a missed one. Contact your prescriber or clinic to arrange the missed injection as soon as reasonably possible and follow their timing guidance. Contact your prescriber if doses are missed repeatedly or if symptoms change.

Per FDA-approved prescribing information for the commercial Delestrogen product, Delestrogen is a depot injectable form of estradiol valerate that is released slowly over days to weeks. According to FDA-approved prescribing information for the commercial Delestrogen product, how quickly symptoms return depends on the dose and injection interval. With injections every 1–4 weeks, symptoms may reappear anywhere from a few days to a couple of weeks after a missed dose. A single missed dose may allow return of menopausal symptoms such as vasomotor symptoms (hot flashes), sleep or mood changes, and may sometimes cause irregular bleeding if you still have a uterus.

• If you remember very soon (within a few days): call your clinic and arrange the injection; this may restore estradiol levels more promptly.
• If you are late but still within your usual dosing interval: your provider may give the injection at the next available visit — per FDA-approved prescribing information for the commercial Delestrogen product, no additional dose is indicated without prescriber direction.
• If you are well beyond your scheduled interval or have worsening symptoms: call your clinician; they may bring you in sooner or may adjust the schedule temporarily.
• Do not inject extra doses unless directed by your prescriber — per FDA-approved prescribing information for the commercial Delestrogen product, additional doses to make up for a missed dose are not indicated.
• Symptoms warranting prompt prescriber contact: Per FDA-approved prescribing information for the commercial Delestrogen product, the FDA labeling describes new heavy bleeding, severe mood changes, chest pain, shortness of breath, leg swelling, or signs of injection-site infection as serious events associated with estrogen-containing products; the FDA boxed warnings for estrogen-containing products specifically address 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.

In short: missing one Delestrogen injection may bring back menopausal symptoms; reach out to your prescriber to reschedule rather than doubling doses. Contact your prescriber if doses are missed repeatedly or if symptoms change, and contact your prescriber promptly if symptoms are severe or unusual.
