Women considering menopausal hormone therapy may encounter pellets, patches, gels, sprays and oral medications. These delivery methods are not interchangeable, and the best option depends on symptoms, uterus status, health history, risk factors, preferences and the exact hormone being prescribed.

What Are Hormone Pellets?
Pellets are implanted under the skin and release hormone over time. Compounded hormone pellets are not FDA-approved finished drug products, and the dose is difficult to promptly change after insertion.
Transdermal Estrogen Patches and Gels
FDA-approved estradiol patches, gels and sprays deliver estrogen through the skin. Transdermal delivery avoids first-pass liver metabolism and may be preferred in some patients after individualized risk assessment.
Oral Menopausal Hormone Therapy
Oral estrogen and oral micronized progesterone are options for selected patients. Oral and transdermal routes have different pharmacology and risk considerations, so route selection should be individualized.
Why Uterus Status Matters
For most women with an intact uterus who use systemic estrogen, adequate progestogen is needed to protect the endometrium. Women who have had a hysterectomy may have different treatment needs.
Are Pellets Better for Menopause?
There is not evidence that compounded pellets are categorically safer or more effective than FDA-approved menopausal hormone therapy. The limited ability to adjust a pellet after insertion is an important disadvantage when compared with patches, gels or tablets.
Which Route Has the Lowest Risk?
No route is lowest-risk for every patient. Age, time since menopause, cardiovascular and blood-clot history, breast and gynecologic history, liver health, symptoms, dose and hormone formulation all influence the benefit-risk discussion.
How Long Should Menopause HRT Be Used?
There is no universal stop date. Treatment should be periodically reassessed based on ongoing symptoms, benefits, risks and patient preferences rather than automatically continued or stopped at a fixed age.
Frequently Asked Questions
Are pellets more “natural” than patches?
No. FDA-approved estradiol products can contain hormone chemically identical to endogenous estradiol. “Bioidentical” does not mean a pellet is safer or more natural.
Can I switch from pellets to a patch or gel?
Potential transitions require individualized timing because an implanted pellet may continue releasing hormone. The prescribing clinician should plan the change.
Do pellets eliminate the need for progesterone?
No. For most women with a uterus using systemic estrogen, adequate endometrial protection remains important regardless of how estrogen is delivered.
