Clinical Overview

What makes women's health compounding different

Approved products cover most of women's hormone care, so a compounded preparation needs a documented reason. National guidance points to two: an allergy to an ingredient in an approved product, such as the peanut oil in an oral progesterone capsule, and a strength or dosage form that approved products do not offer [1][2].

Estriol is a separate case. It has no FDA approved product in the United States, so a prescriber who wants it works with a compounding pharmacy by necessity rather than by preference.

How Mixwell supports these practices

  • Capsules, creams, troches, and vaginal suppositories, depending on the order
  • Custom strengths, including doses between commercial sizes for careful titration
  • Preparations without peanut oil, dyes, or a preservative a patient reacts to
  • Vaginal preparations, including estriol, which has no approved product here
  • Topical postpartum preparations combining actives a prescriber specifies

We keep the same line on evidence that the guidelines do. Compounded hormone therapy is not presented as safer or more natural than approved therapy, and national reviews describe safety concerns including variable dosing and the absence of standardized labeling and warnings [1][2].

Working with our pharmacist

Our pharmacist reviews the hormone, the strength, the base, and the dosage form with the prescribing office, and asks what the preparation needs to do that an approved product cannot. That reason belongs on the prescription, along with each active and strength, the quantity, and the directions.

Estradiol, estriol, and progesterone are handled as hazardous drugs, so these preparations are compounded in our negative pressure containment room rather than on an open bench [3]. Mixwell is a non sterile pharmacy, so injectable hormones and implantable pellets are outside what we prepare. Batch records document every preparation, and finished preparations ship across California.

Formulas Prescribers Order

Each formula is prepared only with a valid prescription. The prescriber decides what is appropriate.

Health Concerns We Support

Common Questions

When is a compounded hormone preparation appropriate?

National guidance points to two situations: a documented allergy to an ingredient in an FDA approved product, and a documented need for a dosage form that approved products do not offer. Preference alone is not one of them. Your provider documents the reason and writes the prescription, and Mixwell prepares it to that order.

Are compounded hormones safer than FDA approved hormones?

No. National reviews describe safety concerns with compounded hormone therapy, including limited regulation, dosing that can run high or low, and the absence of a label listing risks. Compounded preparations are not reviewed by the FDA. They exist for patients who cannot use an approved product, and that decision belongs to your prescriber.

Is saliva testing used to set hormone doses?

Saliva and urine hormone testing are considered unreliable for setting doses and are not recommended, and blood testing is rarely needed. Your provider decides what monitoring makes sense for you, based on your symptoms and history rather than on a test result alone.

How does a prescriber send a compounded prescription to Mixwell?

Prescribers can call, fax, or send an electronic prescription. The order should name each active ingredient and its strength, the base or vehicle, the dosage form, the quantity, and the directions. Our pharmacist confirms anything unclear before compounding, and can talk through vehicle options for the oral cavity beforehand.
