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.

If you’re interested in how customized medications are used in specific areas of care, see our Dermatology Compounding, Women’s Health, Men’s Health, and Veterinary Compounding.

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 FormCommon UsesWhy It May Be Chosen
CapsulesCustomized strengthsDose flexibility when commercially available strengths are unsuitable
Oral LiquidsChildren and older adultsEasier to swallow than tablets or capsules
Topical CreamsDermatologyLocalized application to the skin
GelsDermatology and localized therapyLightweight topical formulation
OintmentsSkin conditionsLonger-lasting protective barrier
TrochesCertain oral applicationsDissolve slowly in the mouth
SuppositoriesAlternative administrationWhen oral dosing isn’t suitable
Sterile PreparationsPatient-specific sterile prescriptionsPrepared 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 MedicationCompounded Medication
Produced in standardized strengthsPrepared for an individual patient
Manufactured in large quantitiesPrepared in response to a valid prescription
Standard dosage formsAlternative dosage forms may be available when appropriate
FDA approval applies to marketed drug productsCompounded medications are not FDA-approved
Intended for broad patient populationsIntended 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

As healthcare moves toward more patient-centered treatment approaches, personalized medication strategies continue to receive greater attention.

Growth of the Compounding Pharmacy Market

Industry research estimates that the global compounding pharmacy market is valued at more than USD 14.81 billion and is expected to continue growing over the coming years. While market forecasts vary between research organizations, most identify similar growth drivers:

  • Increasing demand for personalized medicine
  • Growing elderly population
  • Rising prevalence of chronic health conditions
  • Expanding veterinary healthcare
  • Greater awareness of customized treatment options

These trends suggest that compounding will continue serving an important role within modern pharmacy practice.

Why Compounding Continues to Matter

Healthcare has changed significantly over the past several decades. Patients are living longer, managing multiple chronic conditions, and expecting care that is increasingly personalized. Although commercially manufactured medications meet the needs of millions of people every day, they cannot address every clinical situation. Some patients require:

  • Different strengths
  • Alternative dosage forms
  • Modified formulations
  • Specific inactive ingredient considerations
  • Individualized treatment approaches

Compounding exists to help address those situations when a licensed healthcare provider determines that customization is medically appropriate. Rather than replacing commercially available medications, compounding complements traditional pharmaceutical care by providing individualized solutions for patients with unique needs.

Choosing a Compounding Pharmacy

If you or your healthcare provider are considering a compounded medication, selecting the right pharmacy is an important part of the process.

Questions to Ask Before Choosing a Compounding Pharmacy

Questions you may wish to ask include:

  • Is the pharmacy licensed in its state of operation?
  • Does it compound the type of medication prescribed?
  • How are ingredients sourced?
  • What quality standards are followed?
  • Can a pharmacist answer my questions?
  • How should the medication be stored?
  • What is the expected beyond-use date?
  • What follow-up support is available if I have questions?

Open communication between the patient, pharmacist, and prescribing provider helps support safe and informed medication use.
