People who can't swallow pills
Children, older adults, and anyone with difficulty swallowing. The same active ingredient can often be prepared as a liquid suspension, a cream, or a troche that dissolves in the mouth.
A plain-language guide
What is compounding?
The short answer
Pharmaceutical compounding is the practice of preparing a medication individually for one patient, on the order of a licensed prescriber. Instead of dispensing a mass-manufactured drug in a fixed strength and form, a compounding pharmacist combines ingredients to create a specific preparation — a different dose, a different delivery form such as a cream or liquid, or a version that leaves out an ingredient the patient reacts to.
Compounding is a regulated pharmacy practice. Compounded preparations are not FDA-approved drug products, and they always require a valid prescription.
How does compounding work?
Every compounded prescription follows the same path — from your prescriber's order to a finished preparation made for one person.
-
1
Your prescriber writes the order
Compounding always begins with a licensed prescriber — an MD, DO, NP, PA, naturopathic doctor, dentist, or veterinarian — who decides a custom preparation is clinically appropriate and writes it as a prescription.
-
2
The pharmacist reviews it
A compounding pharmacist reviews the order for dose, form, and appropriateness, and contacts the prescribing office directly if anything needs clarifying. This is a professional judgment, not order-taking.
-
3
Ingredients are selected and documented
Active pharmaceutical ingredients and inactive bases are selected for the formula. Every lot is documented so the finished preparation can be traced back to what went into it.
-
4
The preparation is compounded
The pharmacist prepares the medication in the lab following USP standards — measuring, mixing, and processing it into the prescribed form. Hazardous drugs are handled in dedicated containment.
-
5
It's verified, labeled, and dispensed
The finished preparation is checked for accuracy and consistency, labeled with directions and a beyond-use date, and dispensed to the patient — usually within 24 to 48 hours.
Who is compounding for?
Compounding exists for the gap between a standard prescription and a real person's needs. These are the situations we see most.
People who react to dyes or fillers
Commercial tablets contain binders, dyes, and preservatives that some patients cannot tolerate. A compounded version can leave out a specific problem ingredient while keeping the active drug.
People who need a dose that doesn't exist
Manufactured drugs come in set strengths. When a patient needs a strength between those — or far below them, as with low-dose naltrexone — compounding can make it.
People whose medication was discontinued
When a manufacturer stops making a product, a compounding pharmacy can often prepare the same active ingredient so treatment doesn't have to stop.
Patients on hormone therapy
Bioidentical hormone replacement is frequently compounded because dosing is individualized and often needs adjusting over time in forms like creams, capsules, or troches.
Pets
Animals refuse tablets, and doses for a cat or a small dog often don't exist commercially. Compounding allows flavored liquids, transdermal gels, and tiny accurate doses on a veterinarian's prescription.
What forms can compounded medication take?
The right form is the one a patient will actually use. Your prescriber and our pharmacist decide together.
Capsules
Custom strengths; dye-free and filler-free options
Oral suspensions
Liquids for patients who can't swallow pills
Creams & gels
Applied to the skin; topical or transdermal
Troches
Dissolve in the mouth; no swallowing required
Suppositories
For patients who can't take medication by mouth
Nasal Sprays
Alternative to pills; delivered through the nasal passages
Flavored veterinary forms
Chicken, beef, fish, tuna, liver, and bacon
Oral rinses
Custom mouthwashes for oral pain and ulcers
How is a compounding pharmacy different from a retail pharmacy?
Retail pharmacy
- Dispenses drugs made by manufacturers
- Fixed strengths and forms
- FDA-approved products
- Same product for every patient
- Ingredients are set by the manufacturer
Compounding pharmacy
- Prepares each medication individually
- Custom strengths and delivery forms
- Not FDA-approved products
- Made for one patient's prescription
- Specific ingredients can be left out
Neither is better than the other. A commercially manufactured drug is the right choice for most patients, most of the time. Compounding exists for the times it is not.
Common questions about compounding
Do I need a prescription for a compounded medication?
Yes. Every compounded medication requires a valid prescription from a licensed prescriber. A compounding pharmacy cannot prepare a prescription medication without one. Our pharmacists can work directly with your provider's office to coordinate the formulation.
Are compounded medications FDA-approved?
No. Compounded preparations are not FDA-approved drug products. Compounding is a regulated pharmacy practice in which a licensed pharmacist prepares a medication for an individual patient on a prescriber's order. Compounded medications are not reviewed by the FDA for safety, effectiveness, or manufacturing quality the way commercially manufactured drugs are. Compounded medications are not represented as superior to FDA-approved products.
Is compounding safe?
Compounding is a long-established, regulated pharmacy practice. In California, compounding pharmacies are licensed and inspected by the California Board of Pharmacy, and preparations are made under United States Pharmacopeia standards — USP 795 for non-sterile compounding and USP 800 for hazardous drugs. As with any medication, safety depends on an appropriate prescription and a pharmacy that follows those standards. Discuss any medication with your prescriber.
How long does a compounded prescription take?
Most preparations are ready within 24 to 48 hours, depending on ingredient availability. Complex or specialty formulations can take longer. Call (909) 378-7301 and we'll give you an accurate timeline before you commit.
Does insurance cover compounded medications?
Mixwell does not accept insurance. Pricing varies by formulation, so call (909) 378-7301 to discuss your specific medication and current pricing. You may be able to use an HSA or FSA account for compounded medications; veterinary prescriptions cannot be charged to HSA or FSA accounts.
Can compounding pharmacies make any medication?
No. There are real limits. Compounding cannot be used to copy a commercially available FDA-approved drug without a clinical reason, and some substances cannot be compounded at all. Mixwell also performs non-sterile compounding only — we do not prepare injectables or sterile products. If a preparation is outside our scope, we'll tell you.
Can you compound medication for pets?
Yes, on a valid prescription from a licensed veterinarian. Veterinary compounding is one of the most common reasons pet owners seek out a compounding pharmacy: flavored liquids, transdermal gels, and accurate small doses that don't exist commercially.
Who prescribes compounded medications?
Any licensed prescriber can order a compounded medication within their scope of practice — including physicians (MD, DO), nurse practitioners, physician assistants, naturopathic doctors, dentists, and veterinarians. Compounding is used across almost all medical specialties: dermatology, hormone therapy, OB/GYN, Gastroenterology, pain management, pediatrics, dentistry, and veterinary medicine.
Think compounding might help?
Talk to your prescriber, or call us and we will tell you honestly whether compounding is the right fit for your situation.
