The quick sort
| Item | Waste stream | Where it goes |
|---|---|---|
| Partly used, expired, or past-discard GLP-1 vial | Pharmaceutical waste | Pharmaceutical waste container, sent for incineration |
| Syringe or needle used to draw or inject | Sharps | FDA-cleared sharps container |
| Single-dose autoinjector pen (built-in needle) | Sharps | Whole pen into the sharps container |
| Multi-dose pen with leftover drug | Pharmaceutical waste (needle removed to sharps) | Pharmaceutical waste container |
| Expired or unwanted testosterone | Controlled substance inventory (Schedule III) | DEA-registered reverse distributor |
| Remainder of a testosterone dose just given | Controlled substance wastage | Recorded and witnessed per policy and state rules |
GLP-1 vials are pharmaceutical waste
Compounded semaglutide and tirzepatide usually come in multi-dose vials. Once a vial is partly used, expired, or past its discard date, what’s left is pharmaceutical waste.
- Not sharps. A vial isn’t a sharp, and drug waste doesn’t belong in a sharps container. Sharps are often treated by methods built for infectious waste, not drugs.
- Not trash. Drug left in a vial can be retrieved from a dumpster, and some states restrict businesses from putting drug waste in the trash.
- Not the drain. Pouring it out sends the drug into water.
Semaglutide and tirzepatide aren’t on EPA’s P or U lists, and they aren’t controlled substances. Unless a specific compounded formulation meets a hazardous waste characteristic, it goes in non-hazardous pharmaceutical waste. Check the safety data sheet if you’re unsure.
To keep it simple for staff, many clinics put every GLP-1 vial in the pharmaceutical waste container, partly used or empty. No one has to judge what counts as empty.
Pens, needles, and syringes are sharps
- Syringes and needles used to draw from a vial or inject go straight into an FDA-cleared sharps container.
- Single-dose autoinjector pens have a built-in needle. The whole pen goes in the sharps container.
- Multi-dose pens take a separate pen needle. The needle goes in the sharps container. A pen with drug left in it goes to pharmaceutical waste.
- Replace sharps containers at the fill line. High-volume injection clinics fill them quickly.
Sharps mail-back kits start at $55. See GLP-1 pen disposal for brand-name pens, and sharps container sizes to pick a size.
Testosterone is a controlled substance
Testosterone and other anabolic steroids are Schedule III controlled substances under federal law. A clinic that stocks testosterone needs a DEA registration for that location and DEA-compliant records. Disposal splits two ways.
Expired or unwanted vials: inventory
A multi-dose testosterone vial that reaches its discard date wasn’t part of a dose given to a patient. The conservative approach is to treat the remainder as inventory and send it to the reverse distributor.
The remainder of a dose: wastage

Other drugs clinics stock
- Phentermine is Schedule IV. Expired or unwanted stock goes to a reverse distributor, like testosterone.
- Vitamin B12, lipotropic injections, and other non-controlled injectables go in pharmaceutical waste when expired or partly used.
- Lidocaine and other numbing agents in med spas are non-controlled pharmaceutical waste when expired.
- Blood-soaked gauze or dressings are regulated medical waste in most states. Lightly soiled items usually aren’t; check your state’s definition.
Patients’ leftover medication
Patients who inject at home end up with leftover pens, vials, and needles. DEA and FDA point people to take-back first: a drop box or a mail-back envelope. A clinic can’t accept patients’ controlled substances, such as testosterone, unless it’s registered with DEA as a collector. A medication mail-back kit (from $95) gives patients a take-back option at home, and a sharps mail-back kit covers their needles.
A clinic checklist
- A pharmaceutical waste container in every room where GLP-1 vials are opened.
- A sharps container at every injection point, replaced at the fill line.
- Testosterone and phentermine in a locked cabinet with a perpetual inventory.
- Testosterone wastage recorded and witnessed per your state rules and policy.
- Expired controls pulled on a schedule and sent to a DEA-registered reverse distributor.
- Certificates of Destruction, transfer records, and Form 41 filed together for at least two years.
- A take-back option for patients’ leftover home medication.

Frequently asked questions
How do clinics dispose of partially used semaglutide or tirzepatide vials?
As pharmaceutical waste. A partially used, expired, or past-discard-date GLP-1 vial still holds drug, so it isn't sharps and it isn't trash. Put it in a pharmaceutical waste container and send it for incineration, with a Certificate of Destruction for your records.
Is semaglutide or tirzepatide hazardous waste?
Neither is on EPA's P or U lists. Unless a specific formulation meets a hazardous waste characteristic, unused product goes in non-hazardous pharmaceutical waste. If you're unsure about a compounded formulation, check its safety data sheet or ask your compounder.
Are GLP-1 drugs controlled substances?
No. Semaglutide and tirzepatide aren't controlled substances, so no DEA forms are needed to dispose of them. Phentermine, which many weight-loss clinics also stock, is Schedule IV. Testosterone is Schedule III.
Do GLP-1 pens go in a sharps container?
The needle does. Single-dose autoinjector pens with a built-in needle go whole into the sharps container. For multi-dose pens, remove the pen needle into the sharps container; a pen with leftover drug goes to pharmaceutical waste.
How do TRT clinics dispose of expired testosterone?
Testosterone is Schedule III. Expired or unwanted vials are controlled inventory and go to a DEA-registered reverse distributor for incineration. The reverse distributor completes DEA Form 41 and returns a Certificate of Destruction.
What about the leftover testosterone after a partial dose?
That's wastage. Record it in your administration log, with a witness where your state or policy requires one, and handle it by the method your policy names. It doesn't go on Form 41.
Can patients bring leftover GLP-1 pens or testosterone back to the clinic?
A clinic can't accept patients' controlled substances unless it's registered with DEA as a collector. Point patients to a take-back site or a medication mail-back kit for home use.
