Prometrium vs generic progesterone: verify the capsule and ingredients
At a glance

| Availability limit | A published brand label is not a stock check. | DailyMed flags inactivated NDC codes in this record. It must not be presented as proof of a currently available supplier. |

This is a bounded label comparison, not a verification of every generic on sale. A different dispensed supplier needs a fresh ingredient and substitution check. For budgeting, compare the same prescribed cycle rather than assuming every plan uses a capsule every day.
How to use this comparison
Take the brand and generic names, strength and supplier to the pharmacist. Request the current ingredient list for the actual dispensed product if you have an allergy concern. For budgeting, count the capsules required by the prescribed schedule instead of assuming every progesterone plan uses the same quantity each month. Ask for brand and generic prices using identical days supplied. Keep this comparison tied to the role in your estrogen plan; it is not a recommendation to start progesterone for sleep.
