Bioidentical and compounded: two different questions.
When you are ready to feel better, hormone terminology can make a treatment decision feel harder. Bioidentical. Compounded. Personalized. These words can sound reassuring without explaining much. You deserve to know what is in a prescription, why it was chosen and what evidence supports it.
Bioidentical describes a hormone's molecular structure. Compounded describes how a medication is prepared. A hormone can be bioidentical without being compounded, and neither term by itself proves that a treatment is safer or more effective.
What bioidentical actually means
Bioidentical hormones have the same molecular structure as hormones made by the human body. Estradiol and progesterone are examples. The term describes the hormone, not an assurance that a finished medication is right for every patient.
FDA-approved medicines containing bioidentical hormones are available. You do not have to choose a compounded prescription to use bioidentical hormone therapy. Natural-sounding language is not a substitute for a discussion of benefits and risks.
What changes when a medicine is compounded
Compounding involves preparing or altering a medication to meet a patient's needs. It can serve an important purpose when an approved drug is not medically appropriate, such as an allergy to an ingredient or a need for a different medication form.
Compounded medicines are not FDA-approved. FDA does not review each finished compounded drug's safety, effectiveness and quality before it is marketed. Federal and state oversight still applies; compounding does not mean there are no rules.
That distinction matters when you compare options. An approved product has gone through FDA's review process. A compounded prescription should come with a clear clinical reason for its selection and an explanation of its additional uncertainties.

Ask about approved options, too
ACOG recommends FDA-approved menopausal hormone therapies over compounded preparations when approved formulations are available. Its guidance says compounded bioidentical hormone therapy should not be prescribed routinely in that situation.
Personal care still matters with an approved medicine: your symptoms, medical history and preferences should shape the choice. If a compounded option is proposed, ask why it fits your particular need and what alternatives were considered. That is a reasonable part of making an informed decision.

Look for evidence about the actual treatment
Research supporting hormone therapy generally does not automatically validate every combination, cream or delivery method. The National Academies' review, commissioned by FDA, found that strong clinical evidence for the safety and effectiveness of compounded bioidentical hormone therapy was lacking.
Ask whether a cited study tested the actual formulation, route and regimen being offered. Patient experiences can help you understand someone's experience of care; they cannot establish that another person will have the same outcome.

Understanding Estrada's description
Estrada is Soha's compounded prescription vaginal cream containing bioidentical estradiol and progesterone, intended for systemic hormone therapy. An OB/GYN evaluates every patient and prescribes when appropriate.
Estrada is not FDA-approved. Ask your OB/GYN why a compounded prescription is appropriate for you, what evidence supports the proposed treatment and what follow-up will involve.

A few questions worth taking with you
Save these for your next conversation about hormone therapy:
- Is this finished medication FDA-approved or compounded?
- Which approved options could meet my needs?
- If it is compounded, what is the specific reason for choosing it?
- What studies support this exact formulation and its intended effects?
- What benefits, risks and follow-up should I understand before deciding?
Questions you may still have
Is a compounded medicine the same as a generic?
No. FDA-approved generics go through an approval process. A compounded drug is not an FDA-approved generic, even when an ingredient also appears in an approved medication.

Does bioidentical mean risk-free?
No. Matching a hormone's molecular structure does not remove treatment risks. FDA has not found evidence that compounded bioidentical hormones are safer or more effective than approved hormone therapies.
