Customized Medication Compounding at Webster Pharmacy
State-of-the-art compounding lab in St. LouisWhat is a compounding pharmacy?
There are benefits associated with working with a compounding pharmacy. Our compounding pharmacy focuses on providing patients with custom pharmaceutical products. We prepare custom dosage forms when standard FDA-approved drugs fail to do so, become unavailable, or are no longer produced by a pharmaceutical manufacturer. To learn more about the FDA shortage list click here.
Compounding medicine is the process by which a trained pharmacist makes a custom medication typically for a specific patient or for specific groups of patients.
At Webster Pharmacy, we also believe that compounding professionals should receive ongoing training in compounding to stay up-to-date with this art since most pharmacists no longer practice compounding. Our pharmacist stay up to date with education from the American College of Apothecaries compounding courses.

Frequently asked questions about compounding:
Will my insurance pay for my compound? Typically not, from our experience insurance companies cover products on their formularies. Often, the bases and excipients we used are not on their formularies so they will only cover the active ingredients. Also, insurance companies do not pay for the pharmacists' time involved in preparing the compound.
Can I use my FSA or HSA account to cover compounded products? Yes!
Can you make a cheaper version of a commercially available product? Not typically, if something can not be tolerated in the commercially available dosage form we can make it. One example is if someone has a peanut allergy we can make peanut free progesterone capsules.
Does Webster Pharmacy prepare Injectable meds? We are currently working on building out our sterile pharmacy.
Compounding Services FAQ – Webster RX Pharmacy
Welcome to Webster RX, a licensed non-sterile compounding pharmacy in Webster Groves, Missouri. We create custom medications tailored to individual patient needs using non-sterile (USP <795>) compounding methods. We do **not** perform sterile (USP <797>) compounding such as injectables, ophthalmics, or intrathecal preparations. All compounded medications require a valid prescription from a licensed prescriber.
Compounding is the creation of personalized medications when commercial products don’t meet a patient’s needs (e.g., custom strengths, allergen-free bases, alternative dosage forms like creams, gels, troches, capsules, or suppositories).
Webster RX specializes in **non-sterile compounding** with high-quality pharmaceutical-grade ingredients. We follow strict USP <795> guidelines for non-sterile preparations and Missouri Board of Pharmacy regulations to ensure safety, potency, and consistency.
We focus on non-sterile custom preparations, including:
- Hormone Replacement Therapy (HRT) – bioidentical testosterone, estradiol, progesterone in creams, gels, troches, vaginal suppositories
- Weight Management – compounded oral or sublingual semaglutide, tirzepatide (non-injectable forms only)
- Pain & Inflammation – topical creams/gels (ketoprofen, lidocaine, gabapentin, diclofenac, etc.)
- Dermatology & Skin Rejuvenation – GHK-Cu creams, tretinoin, hydroquinone, niacinamide, peptide blends
- Sexual Health – testosterone or PT-141 troches, vaginal estrogen/testosterone suppositories
