    Drug Shortage Alert

    Estradiol patches on backorder. We compound estradiol.

    Multiple estradiol transdermal patches are on backorder. Your prescriber can order a compounded alternative — cream, gel, or troche — compounded in 1–2 days and shipped to your door.

    Current Status

    What's on shortage

    ASHP has listed estradiol transdermal system as a current shortage since January 30, 2026. The FDA has not designated an official shortage as of September 2026, which limits pharmacies' ability to substitute freely even while shelves are empty.

    Twice-weekly estradiol patches from Amneal (Dotti, Lyllana), Mylan/Viatris, Noven, Sandoz and Zydus
    Strengths affected: 0.025, 0.0375, 0.05, 0.075 and 0.1 mg/day
    Cause reported: demand rising faster than capacity after the FDA removed the boxed warning on hormone therapy in late 2025
    No resupply date published; the ASHP bulletin below is updated as manufacturers report

    Don't stop estradiol abruptly

    Sudden discontinuation of estradiol can cause rebound vasomotor symptoms — hot flashes, night sweats, sleep disruption — and may affect bone density in long-term HRT patients. Your prescriber can transition you to a compounded alternative while maintaining therapeutic hormone levels.

    What to do right now:

    1. 1. Contact your prescribing provider
    2. 2. Ask about switching to a compounded estradiol cream, troche, or capsule
    3. 3. Your prescriber can send the prescription to Generation Pharmacy — we compound in 1–2 days

    Clinical Reference

    Patch → Compounded estradiol cream: typical starting doses

    Patch doses do not convert 1:1 to cream. The patch's labeled dose is the amount delivered systemically per day; compounded cream needs a higher applied dose because only a fraction absorbs through the skin. Route equivalence for approved products (a 0.05 mg/day patch is roughly 1 mg of oral estradiol) follows the Canadian Menopause Society equivalency table and the Menopause Society's 2022 position statement, cited below. No guideline publishes a compounded-cream equivalence. The ranges here are this pharmacy's starting points, confirmed with serum estradiol at 4 to 6 weeks.

    Why the cream dose is higher than the patch dose: A patch's labeled dose (e.g., 0.05 mg/day) is the amount delivered systemically. Cream absorption through the skin is partial and varies by patient, application site, and formulation — so the applied dose must be higher to achieve comparable serum levels. Serum estradiol should be checked at 4–6 weeks post-conversion and dose adjusted accordingly.
    Other dosage forms: We also compound estradiol as sublingual troches and oral capsules. These routes have different bioavailability profiles than topical cream and require individualized dosing — they are not interchangeable at the same mg. Ask our pharmacist for guidance on troche or capsule dosing.
    Considering Bi-Est? Some providers use the shortage as an opportunity to discuss Bi-Est (80/20 estriol/estradiol) formulations — but that is a different clinical decision, not a 1:1 patch conversion. Bi-Est adds estriol, which the patch does not contain. If switching to Bi-Est, the estradiol component should match the target dose while the estriol is an addition. Discuss with the patient before changing therapy.

    Prescribing Reference

    Topi-CLICK dosing & days supply

    We dispense estradiol cream in Topi-CLICK metered-dose applicators. The cream concentration is compounded to your patient's prescribed dose — 2 clicks delivers the full daily dose regardless of strength, keeping it simple for patients.

    30-Day Supply

    Topi-CLICK 35

    2 clicks (0.5 mL) daily

    15 mL fill · 0.25 mL per click

    Standard monthly fill. Concentration = prescribed dose ÷ 0.5 mL.

    60-Day Supply

    Topi-CLICK 35

    2 clicks (0.5 mL) daily

    30 mL fill · 0.25 mL per click

    Same device and concentration as the 30-day, larger fill volume.

    90-Day Supply

    Topi-CLICK 140

    2 clicks (1 mL) daily

    90 mL fill · 0.5 mL per click

    Larger dispenser, half the cream concentration — same daily dose in 1 mL.

    Sample Rx

    "Estradiol 2 mg/mL topical cream in Topi-CLICK. Sig: Apply 2 clicks (0.5 mL = 1 mg) topically once daily. Qty: 15 mL. Days Supply: 30. Refills: 2." The same 2-clicks-daily sig works at every strength — only the concentration changes, which keeps dosing simple for patients and titration simple for you.

    Application sites

    Rotate application between inner forearm, inner thigh, or behind the knee. Avoid areas with thick skin or heavy hair. Do not apply to breasts. Allow cream to absorb fully before dressing.

    Available Alternatives

    What we compound for estradiol shortage patients

    Estradiol Topical Cream

    Applied to the inner forearm or thigh once daily via Topi-CLICK applicator. Closest analogue to patch — delivers estradiol transdermally, bypassing first-pass liver metabolism.

    Typical range: 0.5 mg to 4 mg per application (2 clicks daily)

    View details

    Bi-Est Cream (Estradiol + Estriol)

    A common BHRT formulation — but a different therapy than estradiol alone. 80% estriol / 20% estradiol. Not a direct patch substitution; discuss with your prescriber before switching.

    Typical range: 1.25 mg to 5.0 mg total estrogen per application

    View details

    Bi-Est Cream, Custom Ratio (Estradiol + Estriol)

    A second Bi-Est ratio option for providers who titrate estradiol and estriol differently than the classic 80/20 formulation.

    Typical range: Custom ratios per prescriber

    View details

    Estradiol Sublingual Troche

    Dissolves under the tongue for rapid absorption. Bypasses first-pass metabolism. Some providers prefer this for patients who don't tolerate topicals.

    Typical range: 0.25 mg to 1.0 mg daily

    View details

    Vaginal Estriol Cream

    For patients whose primary concern is vaginal atrophy/GSM rather than systemic menopausal symptoms. Local action with minimal systemic absorption.

    Typical range: 0.5 mg to 1.0 mg per application

    View details

    Progesterone (if applicable)

    Women with an intact uterus on estradiol typically need concurrent progesterone. We compound oral capsules and topical creams in custom strengths.

    Typical range: 50 mg to 200 mg daily, per prescriber's protocol

    For Prescribers

    Transitioning a patient from patch to compound

    1

    Choose the alternative

    Topical estradiol cream is the closest analogue to the patch. Troches are an option for patients who prefer sublingual. Bi-Est (estradiol + estriol) is a separate clinical decision — not a 1:1 patch conversion.

    2

    Choose a starting dose

    Cream doses are higher than patch delivery rates because only a fraction absorbs transdermally. Use the dose ranges above as a starting point. Adjust based on serum estradiol levels at 4–6 weeks.

    3

    Prescribe to Generation Pharmacy

    ePrescribe via SiPrescribe (NCPDP: 5685271), call, or fax. We compound in 1–2 business days and ship directly to your patient.

    4

    Confirm with labs

    Check serum estradiol at 4–6 weeks. Adjust dose if levels are below target range. Consider trough levels for twice-daily dosing.
