Why compounding
When a manufactured drug doesn't fit the patient.
Compounding lets a prescriber order exactly what one patient needs, when a commercial product can't provide it.
No commercial option fits
We compound patient-specific medications when a suitable commercial product doesn't exist or isn't appropriate, following your provider's prescription.
Personalized strength and dosing
Exact strengths, including micro-doses, and titration schedules tailored to your treatment plan.
Alternative dosage forms
Capsules, oral liquids, transdermal creams and gels, troches, suppositories, ophthalmics and sterile preparations, as directed by your provider.
Fewer problem ingredients
Formulations can be prepared without common excipients such as dyes, sugar, lactose, gluten or alcohol when your prescriber requests it.
Fewer bottles to manage
When clinically appropriate, compatible medications can be combined into a single preparation to simplify administration.
Prescription required. Compounded medications are prepared under federal and state regulations and USP standards; they are not reviewed or approved by the FDA. Availability of certain compounds may vary by state law and clinical appropriateness.

FAQ
Frequently asked questions.
What is a compounding pharmacy?
A 503A compounding pharmacy makes patient-specific medications, with a custom strength, ingredients and dosage form, to your prescriber's directions. AccuMix prepares sterile and non-sterile forms under USP 795, 797 and 800 standards.
When is a compounding pharmacy necessary?
When a commercial drug doesn't fit the patient: a different strength or titration is needed, an alternative dosage form (liquid, troche, transdermal, sterile injection or ophthalmic), an allergen or additive must be avoided (dyes, lactose, gluten, alcohol), a drug is in shortage or discontinued, or compatible medications need to be combined.
What forms are compounded medications available in?
Sterile: injections, IVs and ophthalmics. Non-sterile: capsules, oral liquids, troches and ODTs, creams, gels, ointments and lotions, transdermals, suppositories, and nasal sprays and rinses.
Which providers can prescribe compounded medications?
Licensed prescribers in the patient's state: MD/DO, NP/APRN, PA, DDS/DMD, DPM, OD/ophthalmology (where permitted), DVM (animals), and ND/NMD in eligible states. DEA registration is required for controlled medications.
Is pharmaceutical compounding different from drug manufacturing?
Yes. 503A compounding is custom, patient-specific prescription work. It is not mass-produced, and it follows USP standards; compounded medications are not FDA-approved products. Manufacturing is FDA-approved mass production under cGMP for resale. 503B outsourcing is a separate FDA-regulated model for office-use batches.
Who regulates compounding pharmacies?
State Boards of Pharmacy (licensure, inspections and 503A rules), the FDA (enforcement of the FD&C Act; the FDA does not approve compounded medications), the DEA (controlled substances), and USP standards 795, 797 and 800.
