What Is a Compounding Pharmacy?
A compounding pharmacy is a licensed pharmacy that prepares customized medications for individual patients when a healthcare provider determines that a commercially available medication does not adequately meet that patient’s needs.
Rather than manufacturing medications in large quantities, compounding pharmacies prepare prescriptions one patient at a time. Every compounded medication begins with a valid prescription and is formulated according to the prescriber’s directions while considering the patient’s individual requirements.
Customization may involve:
- Preparing a medication in a different strength
- Changing a tablet into an oral liquid
- Creating a topical cream or gel instead of an oral medication
- Removing certain non-essential ingredients, such as dyes or preservatives, when appropriate
- Combining ingredients into a patient-specific formulation when clinically justified
The purpose of compounding is not to replace FDA-approved medications. Instead, it exists to help patients whose medical needs cannot be adequately addressed by commercially available products.
For example, a child who cannot swallow tablets may need the same medication prepared as a flavored liquid. An adult with an allergy to a particular inactive ingredient may require a customized formulation without that ingredient. In other cases, a healthcare provider may prescribe a strength that is not commercially manufactured, making compounding an appropriate option.
Compounding has been part of pharmacy practice for centuries and remains an important aspect of personalized healthcare today. While pharmaceutical manufacturing provides standardized medications for millions of patients, compounding offers individualized solutions when standard products are not appropriate for a specific person’s medical needs.
When Might a Compounded Medication Be Appropriate?
A compounded medication may be considered when a licensed healthcare provider determines that an FDA-approved medication cannot adequately meet a patient’s specific clinical needs.
Some of the most common situations include:
Difficulty Swallowing Medication
Many children, older adults, and individuals with certain medical conditions have difficulty swallowing tablets or capsules. In these cases, a pharmacist may be able to prepare the medication in an alternative dosage form, such as an oral liquid, when appropriate and prescribed.
Customized Strengths
Commercial medications are manufactured in fixed strengths. Occasionally, a patient may require a dosage that is not commercially available. Compounding allows pharmacists to prepare medications in patient-specific strengths when prescribed by a healthcare provider.
Ingredient Sensitivities
Some patients have sensitivities or allergies to inactive ingredients found in commercially manufactured medications, such as certain dyes, flavorings, preservatives, or fillers.
When clinically appropriate, a compounded formulation may be prepared without those non-essential ingredients.
Alternative Dosage Forms
Not every patient benefits from the same method of medication delivery. Depending on the prescription and clinical situation, medications may sometimes be prepared as:
- Capsules
- Oral liquids
- Topical creams
- Topical gels
- Lotions
- Troches
- Suppositories
The most appropriate dosage form depends on the medication, the patient’s needs, and the healthcare provider’s instructions.
Pediatric Care
Children often require medication strengths or dosage forms that differ from those manufactured commercially. Compounding may allow medications to be prepared in child-friendly strengths or liquid formulations that are easier to administer while supporting accurate dosing prescribed by the child’s healthcare provider.
Veterinary Medicine
Animals present unique medication challenges because species, breeds, sizes, and administration preferences vary significantly. Compounded medications may help veterinarians prescribe formulations that are easier for pet owners to administer while meeting the specific needs of the animal.

Dermatology & Hormone Therapy
Healthcare providers may also prescribe compounded preparations in areas such as dermatology or hormone therapy when a patient requires a specific formulation, strength, or dosage form that is not commercially available. As with all compounded medications, these prescriptions should be based on an individualized clinical assessment by the prescribing provider.
See our Dermatology Compounding and Hormone Replacement services to learn how customized formulations may be prepared for patient-specific needs.
A Personalized Approach to Patient Care
Every patient is different. Age, allergies, medical history, treatment goals, and medication preferences can all influence which formulation is most appropriate. Compounding allows pharmacists and prescribers to work together to develop patient-specific medications when commercial options do not adequately address those individual needs.
How Does Medication Compounding Work?
Every compounded medication begins with a valid prescription from a licensed healthcare provider. Unlike commercially manufactured medications that are produced in large batches, compounded medications are prepared for an individual patient based on their unique medical needs.
Although every prescription is different, the compounding process generally follows a structured workflow designed to support accuracy, quality, and patient safety.
Step 1: Prescription Review
The process starts when the pharmacy receives a prescription from a licensed prescriber. Before any medication is prepared, the pharmacist carefully reviews the prescription to ensure it is complete and appropriate. This review may include:
- Patient information
- Medication strength
- Dosage form
- Route of administration
- Quantity prescribed
- Refill instructions
- Clinical considerations
- Potential ingredient sensitivities or allergies
Step 2: Ingredient Verification
Once the prescription has been reviewed, the pharmacist verifies the ingredients required to prepare the medication. This includes confirming:
- Active pharmaceutical ingredients (APIs)
- Pharmaceutical bases
- Excipients
- Stability considerations
- Ingredient quality
- Storage requirements
Step 3: Preparing the Medication
The pharmacist compounds the medication according to established procedures and applicable professional standards. Depending on the prescription, this may involve preparing:
- Capsules
- Oral liquids
- Topical creams
- Gels
- Ointments
- Troches
- Suppositories
- Sterile preparations (when applicable)
Step 4: Quality Verification
Before the medication is dispensed, the preparation undergoes a final verification process. This review may include checking:
- Correct ingredients
- Appropriate strength
- Appearance
- Packaging
- Label accuracy
- Prescription instructions
Step 5: Dispensing & Patient Counseling
Once the prescription is complete, the medication is dispensed to the patient. Depending on the medication, pharmacists may provide guidance on:
- Proper administration
- Storage recommendations
- Beyond-use dates
- Handling instructions
- Questions patients should discuss with their healthcare provider
Types of Compounded Medications
One of the advantages of compounding is the ability to prepare medications in different dosage forms when prescribed by a healthcare provider. The appropriate dosage form depends on the medication, the patient’s medical condition, and the prescriber’s clinical judgment.
| Dosage Form | Common Uses | Why It May Be Chosen |
|---|---|---|
| Capsules | Customized strengths | Dose flexibility when commercially available strengths are unsuitable |
| Oral Liquids | Children and older adults | Easier to swallow than tablets or capsules |
| Topical Creams | Dermatology | Localized application to the skin |
| Gels | Dermatology and localized therapy | Lightweight topical formulation |
| Ointments | Skin conditions | Longer-lasting protective barrier |
| Troches | Certain oral applications | Dissolve slowly in the mouth |
| Suppositories | Alternative administration | When oral dosing isn’t suitable |
| Sterile Preparations | Patient-specific sterile prescriptions | Prepared under applicable sterile compounding standards |
Not every medication can be prepared in every dosage form. The most appropriate option depends on clinical considerations and the prescribing provider’s instructions.
See our Dermatology Compounding services to learn how customized topical medications may be prepared for patient-specific needs.
Sterile vs. Non-Sterile Compounding
Compounding generally falls into two broad categories: non-sterile and sterile. Understanding the difference helps patients appreciate why certain medications require additional safeguards.
What Is Non-Sterile Compounding?
Non-sterile compounding includes medications that do not need to remain sterile during preparation. Examples include:
- Capsules
- Oral liquids
- Creams
- Gels
- Ointments
- Powders
- Suppositories
What Is Sterile Compounding?
Sterile compounding involves medications that must remain free from microbial contamination throughout preparation. Examples may include certain:
- Injectable medications
- Ophthalmic (eye) preparations
- Infusions
- Other sterile formulations prescribed for specific patient needs
Because contamination can pose significant patient safety risks, sterile compounding requires specialized environments, procedures, and quality controls.
Depending on the prescription, sterile compounding may relate to services such as IV Therapy and Ophthalmology Compounding when clinically appropriate.
Who May Benefit from Compounded Medications?
Compounding is not designed for one specific group of patients. Instead, it supports individualized care across many areas of healthcare when commercially available medications are not appropriate for a patient’s needs.
Children
Children often require medication strengths or dosage forms that differ from standard commercial products. For example, a child who cannot swallow tablets may benefit from a liquid formulation prescribed by their healthcare provider. Compounding may also allow for patient-specific strengths when clinically appropriate.
Older Adults
Many older adults take multiple prescription medications. Age-related changes, swallowing difficulties, and individualized dosing requirements may make alternative dosage forms appropriate in some situations. Compounding may help address those patient-specific needs when prescribed by a healthcare provider.
Dermatology Patients
Topical medications are commonly prescribed in dermatology. Compounding may allow healthcare providers to prescribe customized creams, gels, lotions, or ointments tailored to an individual’s prescription requirements.
See our Dermatology Compounding services to learn how customized topical medications may be prepared for individual prescription needs.
Women’s Health Patients
Women’s healthcare needs can vary significantly across different stages of life. Healthcare providers may prescribe compounded medications when a patient requires a customized dosage form or strength not commercially available. This may include patient-specific formulations prescribed as part of an individualized treatment plan.
See our Women’s Health Compounding services.
Men’s Health Patients
Some men’s health prescriptions may require customized strengths or alternative dosage forms based on individual clinical needs. Compounding allows pharmacists to prepare medications according to the prescribing provider’s directions while focusing on the patient’s unique requirements.
Read about our Men’s Health Compounding services.
Veterinary Patients
Every animal is different. Species, size, weight, and behavior all influence how medications are administered. Compounded veterinary medications may be prepared in dosage forms that are easier for pet owners to administer while following the veterinarian’s prescription. This personalized approach can support treatment across a wide variety of companion animals and other species.
See our Veterinary Compounding page for more information.
Compounded Medications vs. Commercial Medications
Although both compounded and commercially manufactured medications aim to support patient care, they serve different purposes.
| Commercially Manufactured Medication | Compounded Medication |
|---|---|
| Produced in standardized strengths | Prepared for an individual patient |
| Manufactured in large quantities | Prepared in response to a valid prescription |
| Standard dosage forms | Alternative dosage forms may be available when appropriate |
| FDA approval applies to marketed drug products | Compounded medications are not FDA-approved |
| Intended for broad patient populations | Intended for patient-specific medical needs |
Neither option is inherently “better.” In many cases, an FDA-approved medication is the preferred choice. Compounding becomes relevant when a healthcare provider determines that a commercially available product does not adequately meet an individual patient’s needs.
For this reason, decisions about compounded medications should always be made collaboratively between the patient, the prescribing healthcare provider, and the pharmacist.
Safety & Quality Standards in Compounding Pharmacy
When patients hear the term compounding pharmacy, one of the first questions they ask is:
“Are compounded medications safe?”
The answer requires some context. Compounded medications can play an important role in patient care when prescribed appropriately. However, unlike commercially manufactured drugs, compounded medications are not reviewed or approved by the U.S. Food and Drug Administration (FDA) before they are dispensed. Because of this, quality standards, professional oversight, and proper pharmacy practices become especially important.
Patient safety depends on several factors, including pharmacist expertise, ingredient quality, adherence to compounding standards, and collaboration between the pharmacy and the prescribing healthcare provider.
Understanding Quality Standards
Compounding pharmacies don’t simply mix ingredients together. Professional pharmacy practice follows established standards designed to promote consistency, accuracy, and patient safety throughout the preparation process. These standards help guide:
- Ingredient handling
- Equipment maintenance
- Preparation procedures
- Documentation
- Storage requirements
- Personnel training
- Environmental controls
- Quality assurance
USP <795>: Standards for Non-Sterile Compounding
Many compounded medications—including capsules, creams, oral liquids, gels, and ointments—are considered non-sterile preparations. United States Pharmacopeia (USP) General Chapter <795> establishes professional standards for preparing these medications. The chapter provides guidance on topics such as:
- Proper compounding procedures
- Documentation requirements
- Equipment cleaning
- Ingredient storage
- Beyond-use dating
- Personnel responsibilities
- Quality assurance practices
USP <797>: Standards for Sterile Compounding
Some medications must remain completely sterile during preparation. Examples may include certain injectable medications, ophthalmic preparations, and infusion therapies. USP General Chapter <797> establishes standards for sterile compounding to help reduce risks such as:
- Microbial contamination
- Incorrect preparation
- Improper storage
- Environmental contamination
- Patient exposure to unsafe sterile products
Sterile compounding typically requires specialized cleanroom environments, environmental monitoring, validated procedures, and additional personnel training beyond what is generally required for non-sterile preparations.
The Role of the Pharmacist
Compounding pharmacists do far more than prepare medications. They serve as an important part of the healthcare team by reviewing prescriptions, evaluating dosage forms, considering ingredient compatibility, and communicating with prescribers when clarification is needed. Responsibilities may include:
- Reviewing prescriptions
- Evaluating dosage forms
- Identifying potential formulation issues
- Confirming ingredient availability
- Counseling patients
- Answering medication questions
Quality Starts Before the Medication Is Made
Many patients focus only on the final medication. In reality, quality begins much earlier. It starts with:
- Qualified ingredient suppliers
- Appropriate storage conditions
- Equipment maintenance
- Documentation systems
- Staff training
- Environmental monitoring
- Standard operating procedures
Each step contributes to the consistency and quality of the final preparation.
Compounding Pharmacy Statistics & Industry Trends
While compounding has been part of pharmacy practice for generations, its importance continues to grow alongside personalized healthcare. Below are several statistics that help illustrate why individualized medication remains relevant today.
Prescription Medication Use
According to the CDC’s National Health Interview Survey (NHIS):
- 82.7% of older adults had prescription drug coverage, highlighting the widespread use of long-term medication therapies among the aging population.
- 7.7% of U.S. adults reported not taking medication as prescribed because of cost during 2024, demonstrating that medication access and adherence remain important healthcare challenges.
- The CDC continues to report that prescription medication use increases with age, reinforcing the need for individualized medication management in many patient populations.
Older Adults & Medication Use
Medication use is especially common among older adults. Recent CDC data shows that approximately 88.6% of adults aged 65 years and older reported using prescription medication during the previous 12 months. As patients age, healthcare providers often manage multiple chronic conditions, changing medication requirements, and individualized dosing considerations.
Growth of Personalized Medicine
Personalized medicine continues to influence healthcare worldwide. Factors contributing to this growth include:
- Aging populations
- Increased prevalence of chronic diseases
- Greater focus on individualized care
- Advances in pharmaceutical science
- Expanded collaboration between pharmacists and healthcare providers
