How to Switch From Compounded to FDA-Approved HRT

A lot of women discover months in that the "bioidentical hormones" they have been taking are compounded preparations rather than FDA-approved products. Sometimes that is fine and was the right clinical choice. Often it was never really a choice at all, because nobody spelled out the difference.

If you would rather be on an approved product, switching is usually straightforward, frequently cheaper, and does not mean starting your dose from scratch.

First, find out what you are actually taking

Look at the label and the pharmacy that dispensed it. Signals that a preparation is compounded include a pharmacy name rather than a manufacturer, a strength that is not a standard commercial one, a cream or troche made "for" you, and a combination of two hormones in a single custom cream.

If it is not obvious, ask directly: "Is the product I am receiving an FDA-approved product or a compounded preparation, and which pharmacy dispenses it?" A provider that will not answer that plainly has answered a different, more useful question about itself.

What the difference actually means

FDA-approved products went through federal review for safety and efficacy, and every batch is manufactured to a standardised potency. Compounded preparations are mixed by a pharmacy for an individual patient, usually from FDA-approved active ingredients, but the finished preparation is not reviewed for safety, efficacy or batch-to-batch consistency.

The practical difference is dose predictability, and it is largest with creams, where how much hormone actually reaches your bloodstream varies with the base used and your own absorption.

"Bioidentical" does not settle this either way. It describes the molecule, not the regulatory status, and FDA-approved bioidentical estradiol and micronized progesterone both exist. Our full explainer on compounded versus FDA-approved hormones covers the distinction properly.

The approved equivalents to ask for

Most compounded regimens have a straightforward approved counterpart:

• Compounded estradiol cream or gel maps to an FDA-approved estradiol patch, gel or spray. The patch is often the easiest swap, because dosing is precise and transdermal delivery is generally preferred where clotting risk matters.
• Compounded oral estradiol maps to an approved estradiol tablet, which is also one of the cheaper generics in common use.
• Compounded progesterone cream maps to an approved micronized progesterone capsule. This is the most important swap on the list if you have a uterus, because topical progesterone creams have real doubt attached to whether they achieve reliable endometrial protection.
• Compounded vaginal estrogen maps to approved vaginal creams, tablets, inserts and rings.
• Compounded testosterone has no approved female equivalent in the US. If it is still indicated, ask whether a small dose of an approved men's product could replace it, which is the option the Global Consensus prefers; otherwise it stays compounded. See who actually prescribes testosterone for women.

Dose is the part that needs care

This is where the switch is worth doing properly rather than quickly. Compounded and approved products are not always milligram-for-milligram equivalent in what they deliver, particularly with creams, where absorption varies.

So do not assume your new dose is simply the same number. Tell the prescribing clinician exactly what you are on, how you feel on it, and what you have already tried. A good clinician will pick the approved strength closest to your current effective dose and adjust from there, which usually means one adjustment rather than starting at the bottom.

Give it six to eight weeks before judging, and expect the possibility of one tweak.

The cost surprise, which usually goes your way

Compounded hormones are essentially never covered by insurance. FDA-approved ones frequently are.

Generic oral estradiol and micronized progesterone are among the cheaper prescriptions in common use, and with a discount card at a retail pharmacy the monthly cost can land well below a telehealth subscription. If you have a clinician willing to prescribe, this route often beats every platform on price.

What you give up is the convenience and the menopause-specific expertise. That is a real trade, not a trick, and for plenty of women the subscription is worth it. But if cost is what prompted the switch, price the retail generic route before assuming a platform is cheaper.

Who to switch to

If you want to stay with telehealth, the constraint is that most menopause platforms are compounded-only. Winona is the main exception among the well-known brands: its estrogen patch, estrogen tablet and progesterone capsule are FDA-approved products, alongside compounded creams. It does not require bloodwork to start, and it does not serve every state, so check yours.

Gala Health is compounded, which its landing page states in the fine print. If FDA-approved is your reason for moving, it is not the destination, though it remains a reasonable option on price and fifty-state coverage for women who are not making this particular switch.

Your own primary care clinician or gynecologist is also a perfectly good destination for approved generics, and is often the cheapest.
