Primary formulary: Compounded bioidentical estradiol + progesterone (troche, cream, capsule); DHEA

Quick answer

Breast tenderness shows up on the FDA labels for the active ingredients Winona prescribes — Compounded bioidentical estradiol + progesterone (troche, cream, capsule). This page walks through the labelled frequency ranges, what to watch for, and when to call your clinician.

What Winona prescribes and why it matters for breast tenderness

Winona dispenses compounded bioidentical estradiol and progesterone in troche, cream, or capsule form; safety data draws from the FDA-approved active ingredients rather than the compounded product itself. Because Winona prescribes FDA-approved active ingredients, the labelled adverse-reaction tables from those medications describe the frequencies you should expect. Breast tenderness is the single most frequent labelled reaction across all four brands.

Common label-level side effects

Prometrium PIL Section 6.1 lists breast tenderness at 8%

Serious label-level warnings

Drawn from Section 5 (Warnings and Precautions) of the FDA-approved PILs — including the estradiol boxed warning where applicable.

What to ask your provider

“Which SKU in the Winona formulary am I on, and what is its labelled frequency for breast tenderness?”
“Is my breast tendernesslikely a labelled adverse reaction, or something separate that needs its own workup?”
“Would a different delivery route (patch vs. pill, oral vs. transdermal) change my expected frequency?”
“What is the plan if breast tendernessdoes not settle within 2–3 cycles?”
