Women's health compounding in Chino, CA
Mixwell prepares customized women's health formulations to your prescription. Topical creams, sublingual troches, capsules and vaginal preparations, compounded in Chino and delivered across California. We do not compound injectables or pellets.
Women's health compounding is the preparation of a customized medication by a licensed pharmacy, made to a prescriber's written specification. It adjusts an existing drug's strength, ratio, combination, or dosage form when no commercially available product fits the patient.
Mixwell Compounding Pharmacy performs non sterile compounding at 13788 Roswell Ave, Ste 158, Chino, CA 91710. We do not perform sterile compounding, and we do not prepare injectables or pellets. Compounded preparations are not FDA approved, and a valid prescription is required for every preparation.
Start where your patient is
Choose a category to highlight the formulation problems we hear about most from women's health practices. Every option below still requires a prescription and a decision by the treating prescriber.
A two estrogen combination at a chosen ratio is not something you can pull off a shelf. It is prepared individually to what the prescriber writes, which is the main reason these prescriptions come to a compounding pharmacy.
Estradiol, estriol, progesterone, testosterone and DHEA can be combined into a single preparation when the prescriber specifies it, rather than layering separate products through the day.
A troche dissolves in the mouth instead of sitting on the skin. Absorption varies with technique, so it suits patients who will follow the directions consistently.
Vaginal preparations are used for localized symptoms. FDA approved vaginal products exist and are often the right starting point. Compounding covers combinations and strengths those products do not offer.
A mucoadhesive base is designed to adhere to mucosal tissue, which supports retention at the site. Not every base is validated for vaginal use, so this is worth a call before writing.
Multi ingredient ointments prepared to a prescriber's specification, including lanolin free options for patients who react to it. Ask specifically about timing relative to feeds.
Sometimes the problem is a dye, preservative or filler rather than the active. Where the formulation allows, we can prepare it without the specific ingredient.
When a prescriber expects to adjust over time, we can prepare more than one strength, or score a troche so a dose can be divided along a marked line.
Not sure an active will hold up in a given base, or which route suits a patient? Call our pharmacist first. Some actives are poor candidates for certain vehicles and we will tell you.
These are common examples, not a complete list, and not a recommendation for any individual patient. For a specific drug, strength, ratio or dosage form, call (909) 378-7301.
Why the form matters
A cream that feels unpleasant gets skipped. A capsule that cannot be swallowed gets halved. A troche that is chewed rather than dissolved delivers something different from what the prescriber intended. Matching the dosage form to the person is not a convenience, it is part of whether the therapy is taken as written.
For prescribers and practice managers
You reach a compounding pharmacist, not a queue. Ask about base selection, ratio, compatibility, or beyond use dating before the prescription is written. Call (909) 378-7301.
Manufactured products come in fixed strengths, and no manufacturer makes a two estrogen combination at a chosen ratio. We compound to what is written rather than what a factory decided to make.
Most non sterile preparations are ready in one to two business days. Call to confirm for your specific formulation.
Courier in the Inland Empire and Greater Los Angeles, plus shipping to patients and practices statewide.
A USP 795 and USP 800 compliant facility with a negative pressure room for hazardous drug handling.
We are a non sterile pharmacy. We do not prepare injectables, subcutaneous pellets, or anything requiring sterile technique. If a request falls outside our scope we will say so on the first call rather than waste your time.
Read before prescribing or starting
Changing the dosage form does not change the drug. Everything below applies to a compounded preparation exactly as it applies to a manufactured one.
Estrogen and estrogen with progestogen product labeling carries boxed warnings, including warnings relating to endometrial cancer, cardiovascular disorders, breast cancer and probable dementia. Those warnings apply to the drug rather than to who made the preparation, so they apply to a compounded preparation as well. A prescriber weighs individual risks and benefits, discusses the shortest appropriate duration, and decides whether a progestogen is needed. Do not start, stop or change a dose without speaking with your prescriber.
Absorption from a topical cream depends on the site and the amount applied, and absorption from a troche depends on how long it is held in the mouth and how much saliva is swallowed. Two people using the same preparation the same way can absorb different amounts. This is why technique, consistency and prescriber monitoring matter, and why an individual impression of benefit is difficult to interpret on its own.
Several actives used in women's health compounding are not appropriate during pregnancy, and some require care during nursing. Tell your prescriber if you are pregnant, may become pregnant, or are breastfeeding before starting anything. For preparations applied to the breast or nipple, ask specifically about timing relative to feeds and whether anything needs to be wiped away first.
Topical and vaginal preparations commonly cause local effects at the site of application, including irritation, burning, itching, dryness or discharge. Report any new symptom to your prescriber, and contact them promptly for unusual vaginal bleeding, breast changes, chest pain, shortness of breath, leg swelling or a severe headache. These lists are not complete.
How we operate
They have not been reviewed by the FDA for safety, effectiveness, or manufacturing quality. FDA approved products exist across women's health, including oral and transdermal estradiol, micronized progesterone, and several vaginal products. Where an approved product fits the patient, it is generally the appropriate first choice.
Bioidentical describes a molecule that is structurally identical to what the body produces. Several FDA approved products contain bioidentical hormones. The word describes the molecule, not the pharmacy that made it, and it is not by itself a claim about safety or effectiveness.
Every preparation is made for an identified patient from a prescription written by a licensed prescriber. Compounded medications are not available over the counter.
Oral, topical, transdermal, sublingual and vaginal preparations. No injectables, no pellets, nothing requiring sterile technique.
Our lab follows USP 795 for non sterile compounding and USP 800 for hazardous drug handling, with a negative pressure containment room.
Federal law requires that prescription drug promotion, including promotion of compounded drugs, be truthful, accurate and not misleading. Nothing on this page is a claim of safety or effectiveness for any preparation, and nothing here claims a compounded preparation is safer or more effective than an FDA approved product. FDA recommends that consumers and patients talk to their health care professional about their specific circumstances before taking any medication.
Dosage forms
The form is often the whole reason a prescription comes to us. A patient who cannot tolerate an oral capsule, or who needs a preparation placed where the symptom is, changes what makes sense.
Vehicles
The base carries the active through skin or mucosa, holds the preparation stable through its beyond use date, and decides whether a patient finds it pleasant enough to keep using. Name a preference on the prescription or write pharmacist's choice.
Base availability depends on the active ingredient and the intended route. Not every base is validated for vaginal use, so ask our pharmacist before the prescription is written.
For prescribers and practice managers

A pharmacist reviews compatibility, base selection and beyond use dating, then calls your office back with anything that needs a decision.
