Prometrium is an FDA-approved oral capsule containing micronized progesterone that is chemically identical to progesterone of ovarian origin. Its labeled uses include treatment of secondary amenorrhea and prevention of endometrial hyperplasia in postmenopausal women with a uterus who are receiving conjugated estrogens tablets.

Is Prometrium the Same As Progesterone?
A common question is whether Prometrium is the same as progesterone. Prometrium is a brand-name formulation of micronized progesterone supplied in oral capsules. Other progesterone products and dosage forms are also available, including vaginal products, injections, and compounded formulations. Patients should use the specific product, strength, and route prescribed for them because formulations and inactive ingredients can differ.
How to Take Prometrium Capsules
Dosage and timing depend on the reason for treatment and the specific prescription. Patients should follow their healthcare provider’s instructions rather than a generalized dosing or administration schedule found online. Patients should follow the exact dose, schedule, and route on their prescription. For its FDA-approved oral uses, Prometrium labeling directs administration at bedtime because dizziness or drowsiness may occur. If a prescriber provides different instructions for an off-label use, patients should follow that individualized regimen.
Patients should not change their schedule or assume that a missed dose has made treatment ineffective. If a dose is missed during a fertility protocol, contact the prescribing fertility clinic or pharmacist for instructions specific to the prescription.
Storage and Management of Your Prometrium Prescription
Prometrium should be stored at 25°C (77°F), with permitted excursions from 15°C to 30°C (59°F to 86°F), protected from excessive moisture, and kept in a tight, light-resistant container. Patients should follow the storage instructions on the pharmacy label and contact the pharmacy if they are concerned that the medication was stored outside the recommended conditions.
Keeping the original packaging or instruction leaflet can help patients keep track of the medication strength, expiration date, and storage instructions, especially when taking multiple medications. If there is concern about storage conditions or exposure to heat during shipping, contact the pharmacist before using the medication.
When Should You Consult Your Physician While Using Prometrium
Prometrium can cause serious side effects in some patients. The current patient information advises contacting a healthcare provider right away for warning signs such as changes in vision or speech, a sudden severe headache, severe chest or leg pain with or without shortness of breath, dizziness or faintness, or other unusual symptoms that are concerning.
Patients should tell their healthcare provider about other medications and supplements they are taking and discuss any concerns about possible interactions or side effects. Current Prometrium labeling states that the capsules should not be used during pregnancy. Patients who become pregnant while taking Prometrium should contact their healthcare provider about their medication.
