To find a pharmacy for your telehealth brand, use the pharmacy your clinician network already fills through, contract your own, or have thimblehub introduce one we work with. Before you sign, check its license in every state you ship to, its FDA category if it compounds (503A compounding pharmacy or 503B outsourcing facility), its accreditation, and its DEA registration if you sell controlled substances. thimblehub sets up and runs your telehealth brand, fully managed, and routes its prescriptions to the pharmacy you contract or your network's pharmacies.
Three ways to get a pharmacy
| Route | What you get | Good fit when |
|---|---|---|
| Your network's pharmacy | Prescriptions go to the pharmacy your clinician network already fills through. Nothing extra to contract. | You want to launch fast and sell what the network's pharmacy stocks. |
| A pharmacy you contract | Your own price per fill, your packaging and inserts, your formulas, and a relationship you keep if you change networks. | You want control of margin and the unboxing, or you sell compounded formulas. |
| A pharmacy we introduce | thimblehub introduces pharmacies we work with. You agree terms with the pharmacy directly, and we connect it. | You don't have a pharmacy yet and want one that already fills for telehealth brands. |
Any route works with thimblehub. If you change pharmacies later, we connect the new one and your checkout and portals stay as they are. Own a licensed pharmacy already? Pharmacies launching their own brand covers routing your brand's prescriptions back to it. If you still need clinicians, clinician networks compared covers that side.
503A or 503B: which pharmacy you need
If you sell FDA-approved drugs, any pharmacy licensed in your patients' states can fill them. Compounded medicines change the question, because federal law splits compounders into two kinds.
| Rule | 503A pharmacy | 503B outsourcing facility |
|---|---|---|
| Who oversees it | Its state board of pharmacy, day to day | FDA, which inspects on a risk-based schedule |
| Prescription for each patient | Required | Optional. It can also make office stock. |
| Quality rules | USP compounding standards and its state's rules | Current good manufacturing practice (CGMP) |
| Bulk ingredients | USP monograph, an approved drug's ingredient, or FDA's 503A list | Only from FDA's 503B clinical-need list, or for a drug in shortage |
| Copies of approved drugs | Not regularly or in inordinate amounts, unless the prescriber documents a significant difference for that patient | Not allowed, unless the approved drug is in shortage or the prescriber determines a clinical difference for the patient |
| How to verify it | State board license search | FDA's registered outsourcing facility list |
From 21 U.S.C. 353a and 353b and FDA's compounding pages. Compounded drugs are not FDA-approved. Checked October 12, 2026.
A telehealth order is a prescription for one patient, which is the work a 503A pharmacy does. For GLP-1s the copy rule decides what you can sell at all, and how to start a GLP-1 telehealth business walks through it.
Eight checks before you sign
Ask the pharmacy to prove each one in writing, then confirm what you can yourself in the records listed in the next section.
Tick what you have. We sort out the rest with you.
Where to look each one up
| Check | Where to look | What good looks like |
|---|---|---|
| State licenses | Each state board of pharmacy's license search. FDA's BeSafeRx page and NABP's directory link every board. | Active in its home state, plus a nonresident license in each state you ship to. California needs a separate nonresident sterile compounding license for compounded sterile drugs. |
| 503B registration | FDA's registered outsourcing facility list, 98 facilities as of September 30, 2026 | Registered this year, with its last inspection, any Form 483 and any action reviewed. Facilities that don't re-register by December 31 drop off on January 1. |
| Accreditation | ACHC's accredited organization search for PCAB, and NABP's list of accredited compounding pharmacies | Current, and covering the work it does: USP 795 for nonsterile, 797 for sterile, 800 for hazardous drugs |
| Online pharmacy status | LegitScript's certification lookup, by website | Certified, if the pharmacy sells to patients on its own site. LegitScript certifies pharmacies as well as telehealth brands. |
| Controlled substances | The pharmacy's DEA registration certificate | Registered for the schedules you sell, with software that meets DEA's electronic prescribing rules (21 CFR 1311) |
| E-prescribing | Ask, then prove it with a test order | Connected to Surescripts, where virtually all pharmacies e-prescribe and 98.3% are enabled for controlled substances |
From state boards, NABP, FDA, ACHC, LegitScript, DEA (eCFR) and Surescripts' 2025 impact report, listed under Sources. Checked October 12, 2026.
Three answers end the conversation: the pharmacy calls its compounded drugs FDA-approved (FDA doesn't approve compounded drugs), it can't show a license for a state you ship to, or it offers routine copies of an approved drug at volume.
From first call to first order
thimblehubChoose your route
You pick a route: your network's pharmacy, your own contract, or an introduction from thimblehub to a pharmacy we work with.
Checks and contract
You run the eight checks and sign the pharmacy agreement, with your attorney reading it first.
Pharmacy access
You share your pharmacy's ordering account with us, when prescriptions go to your own pharmacy.
Products mapped, dispatch on
thimblehub maps your products to the pharmacy and turns on dispatch. Your network's clinicians approve each order, and approved prescriptions go straight to the pharmacy.
A backup pharmacy
You sign a backup pharmacy, and thimblehub connects it the same way.
A test order, together
You and thimblehub place a test order through intake, payment, clinician review and pharmacy dispatch. Then you go live.
Setup with a pharmacy and network already in place can have you live as fast as 3 days after you sign. Still need a pharmacy? Your launch date moves with the contract, and what to expect when you start shows the rest of setup.

Frequently asked questions
- How do I find a compounding pharmacy for my telehealth brand?
- Ask your clinician network which pharmacies it fills through, ask other brands, or have thimblehub introduce one we work with. Then verify it yourself: a license in every state you ship to, 503A or 503B status, PCAB or NABP accreditation, DEA registration for controlled substances, and prices and turnaround in writing.
- Do I need my own pharmacy to start a telehealth brand?
- No. You can use the pharmacy your clinician network fills through, contract your own, or have us introduce one. Your own contract gives you your price per fill, your packaging and a relationship you keep if you change networks.
- How do I choose a pharmacy partner for a telehealth startup?
- Pick a route first: your network's pharmacy, one you contract, or one thimblehub introduces. Then run the eight checks: state licenses, 503A or 503B status, accreditation, DEA registration if you sell controlled substances, e-prescribing, shipping terms, price and terms in writing, and a backup pharmacy.
- Can a telehealth platform send prescriptions to my own pharmacy?
- With thimblehub, yes. We route prescriptions to the pharmacy you contract or your network's pharmacies. We map your products to your pharmacy and turn on dispatch, and approved prescriptions go to it after clinician review.
- What's the difference between a 503A pharmacy and a 503B outsourcing facility?
- A 503A pharmacy compounds for individual patients against a prescription and is overseen by its state board. A 503B outsourcing facility registers with FDA, follows CGMP and can compound without a prescription for each patient, but only from bulk ingredients on FDA's 503B list or for drugs in shortage.
- Does my pharmacy need a license in every state I sell to?
- Plan on it. FDA tells patients to check that an online pharmacy is licensed by their own state's board, and states such as California license out-of-state pharmacies that ship to their residents. California also requires a California-licensed pharmacist-in-charge from July 1, 2026, and a separate license for sterile compounding.
- Should I have a backup pharmacy?
- Yes. A second pharmacy licensed in the same states keeps refills moving if your main pharmacy loses a license, runs short or slows down. We connect it the same way as your first.
