Concerns we are asked about

Mixwell Compounding Pharmacy is about 10 miles from Walnut, CA, in Chino, up Grand Avenue or the 60. Walnut sits in the Walnut Valley between the San Jose Hills and the Puente Hills. Many Walnut households span generations under one roof, so a single prescriber may be treating a young child who can't swallow a tablet and an older adult managing several medications at once. Lactose is a common tablet and capsule filler, and dyes or preservatives cause problems for some patients. We prepare flavored oral suspensions, lactose free and dye free formulations, and custom strengths, along with pain management and dermatology preparations, to a prescriber's exact order. Mixwell is non sterile only; we do not compound sterile preparations or injectables.

Questions from Walnut patients

What is a compounding pharmacy?

A compounding pharmacy prepares a medication for one patient, to a prescriber's written order, by combining or adjusting ingredients. It is used when an approved product does not fit, such as when a patient needs a different strength, a liquid instead of a tablet, or a formula without an ingredient they react to.

Can a medication be made dye free or sugar free for a child?

Often yes, when the prescriber orders it. A compounding pharmacy can leave out a specific dye, sugar, or flavor a child reacts to, and can add a flavor the child will accept. Some preparations still need a preservative to stay stable, and the pharmacist will tell you when that applies.

Do you accept insurance, and how much does a compounded medication cost?

Mixwell does not accept insurance. Pricing depends on the ingredients, the strength, the form, and the quantity your prescriber orders, so we quote each prescription individually. Call the pharmacy for pricing and any current specials before we compound, so there are no surprises.

How do I transfer a prescription to Mixwell?

Call the pharmacy with your current pharmacy's name and phone number, and the prescription number if you have it. Our pharmacist contacts your current pharmacy and handles the transfer. Please share health details by phone rather than through website forms or email, so they stay protected.

Do you deliver to Walnut?

Yes. We deliver from our Chino lab to Walnut and across California. Call (909) 378-7301 and we will confirm delivery to your address.

How long does a compounded prescription take?

It depends on the formulation and on ingredient availability. We confirm timing with you by phone when we receive the prescription, and we tell you if an ingredient is on backorder.

Do I need a prescription?

Yes. Every compounded preparation is made from a valid prescription written by a licensed prescriber. We can contact your prescriber or your current pharmacy for you.

Do you take insurance, and can I use an HSA or FSA card?

Mixwell does not accept insurance. You should be able to use an HSA or FSA card for compounded medications, though not for veterinary prescriptions. Call (909) 378-7301 for pricing.
