TL;DR
A compounding pharmacy can prepare medication for a specific patient or clinical need, but a compounded drug is not a generic drug. Before paying, we recommend confirming the clinician, dispensing pharmacy, active ingredient, state licenses, total cash price, and shipping terms. For GLP-1 vials, check the concentration and prescribed dose on every label. Never reuse syringe-unit instructions from an older refill without verification.
What a compounding pharmacy does
A compounding pharmacy prepares medication for an individual patient or clinical need when an available manufactured product is unsuitable. Depending on the prescription and applicable rules, the pharmacist may adjust the strength, dosage form, flavor, or inactive ingredients.
For example, a patient may need a liquid instead of a pill or a formulation without a particular dye or preservative. “Custom” does not mean patients can select any drug or dose. The prescriber and pharmacist must assess the request, and the prescription must comply with federal and state requirements.
Compounded drugs versus generic drugs
A generic drug is an FDA-approved alternative to a brand-name drug and must meet federal approval standards. A compounded drug is prepared under separate compounding rules and generally does not receive FDA premarket approval as a finished product.
For that reason, we do not describe compounded semaglutide or tirzepatide as a generic version of a branded prefilled pen. The formula, concentration, container, and dosing method may differ.
Compounding pharmacy versus regular pharmacy
A retail pharmacy primarily dispenses finished medications made by manufacturers, although some retail pharmacies also offer compounding services.
| Check | Regular retail pharmacy | 503A compounding pharmacy | 503B outsourcing facility |
|---|---|---|---|
| Common role | Dispenses manufactured drugs | Prepares patient-specific compounds | May compound certain drugs for health care facilities |
| Prescription model | Patient prescription | Generally an identified-patient prescription | Separate federal conditions apply |
| Product approval | Often dispenses FDA-approved products | Compounds generally are not FDA-approved | Compounds generally are not FDA-approved |
| Main oversight | State board and applicable federal law | State board and applicable federal rules | FDA oversight and applicable state rules |
A 503A pharmacy generally compounds for identified patients. A 503B outsourcing facility operates under different federal conditions and is not automatically a retail pharmacy serving individual patients.
Who handles each part of online prescription care
Online care may involve several businesses:
- The clinician decides whether treatment and a prescription are appropriate.
- The named pharmacy or facility prepares and dispenses the medicine.
- The platform may coordinate care, payments, or refill requests.
- The carrier handles delivery, not medication or dosing questions.
- The service terms should explain cancellations, refunds, and replacements.
At Temi, we help patients keep medications, care details, and refill needs in one place. The pharmacy named on the label remains the best source for product-specific questions.
FDA-approved, FDA-registered, and state-licensed are different claims
Compounded drugs generally are not FDA-approved as finished products. FDA approval means the agency reviewed a specific product and its labeling before marketing.
FDA registration refers to a facility or regulatory status. It does not mean the FDA approved every product or endorsed the business. Likewise, a state pharmacy license permits a pharmacy to operate within its authorized scope but does not validate every website claim or dosing instruction.
What each claim proves
- FDA-approved product: The named finished product completed the applicable premarket review.
- FDA-registered facility: The facility appears in an FDA system and must follow rules associated with that status.
- State-licensed pharmacy: A state board has granted a license that patients can verify.
- Inspection record: An inspection occurred. The date, findings, responses, and later actions provide necessary context.
We never call a pharmacy “FDA-approved” based only on its registration, inspection history, or 503B status.
Are compounding pharmacies legal, and is a prescription required?
Last reviewed: October 3, 2026.
Compounding is lawful when it meets applicable federal and state requirements. Whether a specific prescription is permitted depends on the drug, ingredient, facility type, patient’s state, and current regulatory conditions.
Patient-specific compounded medication generally requires a valid prescription. Paying a membership or consultation fee does not guarantee that a clinician will prescribe treatment.
For current information, we recommend checking official records:
- FDA Drug Shortages database
- FDA compounding information
- FDA registered outsourcing facilities
- National directory of state boards of pharmacy
How shortages affect compounded semaglutide and tirzepatide
The rules governing copies of commercially available drugs may differ when a drug is in shortage or a documented clinical need exists. Because shortage status and enforcement policies can change, avoid blanket claims that compounded semaglutide or tirzepatide is always permitted or always prohibited.
Our guide to weight loss injections, costs, safety, and refills can help patients prepare for a conversation with their clinician.
Semaglutide base versus salt forms
Ask for the exact active ingredient shown on the prescription and dispensing label. Semaglutide base and semaglutide salt forms should not be treated as interchangeable terms.
We recommend avoiding injectable products labeled “research use only” or sold without clinician review, a valid prescription, and a named dispensing pharmacy.
How to verify a compounding pharmacy before checkout
A polished website is not proof that a pharmacy is properly licensed. Before entering payment details:
- Get the pharmacy’s legal name, address, phone number, license number, and dispensing state.
- Confirm that it may dispense into the patient’s state.
- Verify the license through the relevant state board.
- Check the license status, address, expiration information, and disciplinary history.
- Confirm the clinician’s identity, credentials, and state authority.
- Request the active ingredient, dosage form, concentration, and complete price.
Red flags include no clinician review, no named pharmacy, no pharmacist contact method, a guaranteed prescription, “research use only” ingredients, or claims that a compound is an FDA-approved generic.
Quick verification checklist
Before payment, we suggest confirming:
- Clinician and dispensing pharmacy identities
- Active pharmacy license and state authority
- Active ingredient and dosage form
- Concentration and prescribed dose
- Syringe units, when applicable
- Vial volume, storage instructions, and beyond-use date
- Shipping, cancellation, refund, replacement, and refill terms
A beyond-use date is not the same as a manufacturer’s expiration date. Keep the invoice, label, pharmacy phone number, and shipping records. If medication arrives warm, frozen, leaking, or damaged, hold it until the pharmacy provides product-specific guidance.
Check the GLP-1 label before every dose and refill
Compounded GLP-1 vials may require patients to measure each dose with a syringe. Check every new label for the active ingredient, concentration, prescribed dose, syringe units if applicable, vial volume, storage instructions, beyond-use date, and pharmacy phone number.
“Units” identify syringe markings; they do not state the drug dose on their own. The same unit marking can deliver a different milligram dose if the concentration changes. Our guide to how milligrams relate to tirzepatide syringe units explains why concentration must be confirmed first.
A refill with a new concentration
A refill may contain the same prescribed milligram dose at a different concentration. In that case, the syringe marking may also change.
If the milligram dose, concentration, and unit instructions do not agree, stop and call the dispensing pharmacist before injecting. Never copy instructions from an old vial or dashboard without checking the current label.
When to call for help
Contact the clinician or pharmacist about side effects, missed doses, dosing questions, or storage problems. Do not double a delayed dose unless the clinician gives instructions for that specific medication and schedule.
Seek prompt medical attention for a severe allergic reaction, persistent vomiting with dehydration, severe abdominal pain, or another acute concern.
Refills, transfers, shipping, and local access
Start the refill process before the final dose. Confirm whether refills remain, which pharmacy will dispense the medication, whether another clinical review is required, and what the total charge will be.
Compounded prescriptions may not transfer like standard retail prescriptions. Formula details, state rules, and pharmacy procedures can affect the process. Our prescription refill support resources help patients organize their questions.
A pharmacy may ship across state lines only where authorized. Kansas patients can check the Kansas Board of Pharmacy, while Oklahoma patients can use the Oklahoma State Board of Pharmacy. Our pharmacy guides for cash-pay prescription services explain common dispensing and payment models.
If the next dose is due and the shipment is late
Call the pharmacy for tracking and storage guidance, then contact the prescriber for missed-dose instructions. Do not use damaged or improperly stored medicine until the pharmacy confirms what to do, and do not change the dosing schedule independently.
What a compounded prescription costs in cash
An advertised price may exclude clinician visits, memberships, supplies, laboratory work, shipping, refill fees, or dose-related price changes.
Before paying, request the amount due now and the expected recurring total in writing. Insurance coverage varies, and many compounded prescriptions are paid for in cash.
Questions to ask before entering a card
- What is due today, and which charges repeat?
- Are visits, medication, shipping, supplies, and laboratory work included?
- Does the price change with dose, concentration, or vial size?
- What are the cancellation and refund deadlines?
- Who handles failed delivery or damaged medication?
- What happens if the clinician does not prescribe?
Frequently asked questions
These answers cover the main distinctions, but we still recommend checking current pharmacy licenses and product information before each fill.
