What Is a Compounding Pharmacy? (And Why It Matters for Patients in Kingsport)

A compounding pharmacy creates custom medications tailored to you. Learn what compounding is, what it treats, and how Marcum's Pharmacy has served Kingsport for 60+ years.

What Is a Compounding Pharmacy? (And Why It Matters for Patients in Kingsport)

Picture this: your doctor writes you a prescription, you take it to a chain pharmacy, and the answer comes back — "we only carry that in 10mg or 50mg." Your provider needs 25mg. The pharmacist shrugs. You leave without a solution.

That scenario plays out more often than it should. And it's exactly the kind of problem a compounding pharmacy is built to solve.

If you've heard the term but aren't sure what it means — or why patients across the Tri-Cities are choosing independent compounding pharmacies over big-box chains — this guide is for you.


The Short Answer: What Compounding Actually Means

Compounding is the process of creating a customized medication for a specific patient. Instead of pulling a pre-manufactured pill off the shelf, a compounding pharmacist prepares the medication from scratch — adjusting the dose, changing the delivery form, removing an allergen, or combining ingredients in a way that a commercial product simply doesn't offer.

It sounds new, but it isn't. For most of pharmacy history, all medications were compounded. Pharmacists mixed, measured, and prepared every prescription by hand. Mass pharmaceutical manufacturing changed that in the mid-20th century — and for most common medications, that's a good thing. But not every patient fits a standard mold.

Today, compounding fills the gaps that mass manufacturing leaves behind. That's why it's growing again — and why practices like personalized hormone therapy, weight-loss medicine, and specialty dosing have brought compounding back into the conversation.


What Makes a Compounding Pharmacy Different From a Regular Pharmacy?

A traditional retail pharmacy — whether it's your local chain or an independent shop — dispenses commercially manufactured medications. The drug, dose, and form are fixed. The pharmacist's job is to verify the prescription and dispense it accurately. That's valuable work, and it covers the vast majority of what most patients need.

A compounding pharmacy does all of that and offers something more: the ability to prepare a medication that doesn't exist in a commercially available form.

Your compounding pharmacist isn't just checking a label — they're formulating. They're making decisions about ingredients, bases, concentrations, and delivery methods. That requires a deeper level of training, specialized equipment, and a hands-on relationship with both the prescribing provider and the patient.

At Marcum's Pharmacy in Kingsport, every compounded medication is prepared by a licensed PharmD. Colton and Catherine Marcum — both pharmacists and the owners of the practice — built the compounding program alongside a team that includes pharmacists with decades of compounding experience. That expertise matters when the medication being prepared is tailor-made for you.


What Can a Compounding Pharmacy Make?

The short answer: quite a bit — as long as it's prepared pursuant to a valid prescription from a licensed healthcare provider. Here's how compounding shows up in real patient care:

Bioidentical Hormone Therapy (BHRT)

Many patients pursuing hormone support for perimenopause, menopause, or hormonal imbalance find that commercially available hormone products don't offer the exact dose or delivery method their provider recommends. Compounded BHRT may allow for customized estrogen, progesterone, or testosterone formulations — in strengths and forms that fit the patient's specific lab results and symptoms, as determined by their provider.

Sublingual GLP-1 Formulations

Compounded semaglutide pharmacy services have grown significantly as patients seek personalized weight-loss support. Certain compounded semaglutide formulations may be available with a valid prescription from a licensed provider. These are not the same as commercially manufactured Ozempic or Wegovy — they are compounded preparations, and their availability is subject to FDA shortage designation status. Our pharmacists can answer your questions about what's currently available and what a prescription pathway looks like.

Low Dose Naltrexone (LDN)

Naltrexone is commercially available, but not in the low doses some providers prescribe for certain autoimmune and inflammatory conditions. Compounding makes those precise doses possible — as directed by your healthcare provider.

Methylene Blue

Precise dosing matters with methylene blue, and our compounding team can prepare formulations under pharmacist-supervised protocols as prescribed.

Veterinary Compounding

Pets have unique needs too. If your dog won't take a tablet or your cat needs a dose that doesn't come in a commercial formulation, a veterinary compounding pharmacy can prepare a flavored chew, a transdermal gel, or a liquid suspension that actually works for your animal.

Alternative Dosage Forms

Sometimes the medication is available commercially — but the form isn't right for the patient. A person who struggles to swallow tablets might do better with a sublingual drop. A child who refuses capsules might accept a flavored suspension. Compounding makes those adaptations possible through troches, topical creams, gels, and more.


Is Compounding Safe? What Patients Should Know

It's a fair question, and you deserve a straight answer.

Compounding pharmacies in Tennessee operate under the oversight of the Tennessee Board of Pharmacy. Marcum's Pharmacy is a 503A compounding pharmacy — which means every compounded medication is prepared for a specific patient, pursuant to a valid prescription from a licensed healthcare provider. 503A pharmacies are not bulk manufacturers. Each preparation is made to order.

It's important to be clear: compounded medications are not FDA-approved. The FDA approves commercially manufactured drugs through a standardized testing process. Compounded medications are prepared based on your provider's prescription and our pharmacists' expertise — they haven't gone through that same approval pathway. That doesn't mean they're unsafe, but it's something every patient should understand going in.

What gives Marcum's patients confidence is the combination of credentials, experience, and relationships. Cephas Sloan has been compounding at this pharmacy since 2000. Zach Carland since 2009. Whitney Nussman has been leading the technical team since 2005. These aren't anonymous technicians at a faceless lab — they're neighbors who've spent careers perfecting this craft in your community.


Does Insurance Cover Compounded Medications?

Honestly? Coverage varies widely, and most compounded medications are not covered by standard insurance plans. That's a real consideration, and we'd rather tell you upfront than let you be surprised at the counter.

A few things worth knowing:

  • Some HSA and FSA accounts can be used toward compounded prescriptions — ask your benefits administrator.
  • Your provider may be able to document medical necessity, which can sometimes support a coverage appeal.
  • In some cases, a compounded formulation is still cost-competitive with a branded drug, even without insurance.

Our pharmacists can walk you through cost and coverage questions — no appointment needed. Just call or stop in.


Frequently Asked Questions

What is the difference between a regular pharmacy and a compounding pharmacy?

A regular pharmacy dispenses commercially manufactured medications in fixed doses and forms. A compounding pharmacy prepares customized medications from scratch for individual patients — adjusting the dose, delivery form, or ingredients based on a provider's prescription. Not every pharmacy compounds; it requires specialized training, equipment, and licensing.

What is compound medicine?

Compound medicine — or a compounded medication — is a drug preparation made specifically for one patient by a licensed pharmacist, based on a prescription from their healthcare provider. It may differ from commercial options in dose strength, dosage form (such as a cream instead of a pill), or ingredient composition (such as removing a dye or allergen).

Can a compound pharmacy make Ozempic?

Not exactly. Ozempic is a branded, commercially manufactured product. However, certain compounding pharmacies may be able to prepare semaglutide formulations — the active ingredient in Ozempic — subject to FDA shortage designation status and with a valid prescription from a licensed provider. These are compounded preparations, not the same as Ozempic. If you're exploring compounded GLP-1 options, our pharmacists can explain what's currently available and what the prescription process looks like.

Can you trust a compound pharmacy?

Yes — if you choose one that operates under proper regulatory oversight. Look for a pharmacy licensed by the state board of pharmacy, staffed by credentialed pharmacists, and operating as a 503A facility (patient-specific compounding). Marcum's has been serving the Tri-Cities under those standards for over 60 years, and our pharmacists are available to answer any question you have about how your medication is prepared.

Do I need a prescription for compounded medications?

Yes. All compounded prescription medications at Marcum's require a valid prescription from a licensed healthcare provider. Compounding is not a workaround for getting medications without a prescription — it's a way to customize a medication your provider has already determined is appropriate for you.

There's no shortage of pharmacies in the Tri-Cities. So why do patients drive past a chain on every corner to fill a prescription here?

Colton and Catherine Marcum didn't inherit a big-box franchise — they built on a legacy of independent pharmacy practice rooted in this community. When you call with a question, you're talking to a pharmacist who knows your name, not a call center.

Part of it is the team. Our compounding pharmacists have decades of combined experience. Our lead technician has been here since 2005. That kind of continuity means something when someone is preparing a medication specifically for you.

And part of it is the approach. We don't believe in one-size-fits-all care. Compounding has always been part of what neighborhood pharmacies do — we've just never stopped doing it.
