USP 800 and Ketamine Troches: The Short Version
USP General Chapter <800> (usually just called USP 800) is a United States Pharmacopeia (USP) standard that tells pharmacies how to receive, store, compound, dispense, and dispose of drugs classified as hazardous. Ketamine appears on the hazardous drug list published by the National Institute for Occupational Safety and Health (NIOSH), so the compounding pharmacy preparing your ketamine troches is expected to follow USP 800 handling procedures. For you as a patient, USP 800 mostly governs what happens before your prescription reaches you: how pharmacy staff handle raw ketamine powder, where it is stored, and how leftover material is discarded. It is not a reason to change the routine your prescriber has already set for you, though a few sensible precautions are still worth knowing at home. See the complete guide to ketamine troches for the full picture of how troches are made and used.
Quick Answer
USP General Chapter 800 is the enforceable United States Pharmacopeia standard for how compounding pharmacies receive, store, prepare, and dispose of hazardous drugs. Ketamine is on the NIOSH hazardous drug list because of reproductive and developmental toxicity data in animal studies, so a pharmacy compounding your ketamine troches must follow USP 800 handling procedures. This standard governs pharmacy operations, not your day-to-day use, so your prescriber's directed routine for taking troches does not change because of it. At home, ordinary precautions such as handwashing, secure storage, and proper disposal of unused doses still apply.
What USP 800 Requires From a Compounding Pharmacy
USP 800 sets baseline requirements for any healthcare setting that handles hazardous drugs, including retail and specialty compounding pharmacies. For a pharmacy preparing ketamine troches, that can include designated storage and preparation areas separate from non-hazardous medications, engineering controls for staff who manipulate raw ketamine powder, personal protective equipment such as gloves and gowns, staff training and competency checks, and documented procedures for hazardous waste. These requirements work alongside USP 797 sterile compounding standards for injectable preparations and USP 795, which covers the non-sterile dosage forms most ketamine troches are made from.
USP 800 has carried official compendial status since 2019, but many state boards of pharmacy tied full enforcement to the revised USP 795 and USP 797 chapters, which became official on November 1, 2023. As of 2026, most state pharmacy practice acts expect compounders handling hazardous drugs to follow USP 800, and third-party accreditation reviews often check for it. If you are comparing pharmacies, this is one of several quality markers worth asking about; see how it fits into the broader question of compounded versus commercial troches.

Compare optionsIs Ketamine Really a "Hazardous Drug"?
NIOSH defines a hazardous drug as one that can pose a risk to healthcare workers who handle it repeatedly during preparation, through inhalation, skin contact, or accidental ingestion of powder or residue. Drugs qualify under six criteria: carcinogenicity, teratogenicity or developmental toxicity, reproductive toxicity, organ toxicity at low doses, genotoxicity, or a structure and toxicity profile similar to an existing hazardous drug. Ketamine's inclusion is tied to reproductive and developmental toxicity signals identified in animal research, not to the therapeutic dose you take as directed by your prescriber. NIOSH's framework addresses occupational exposure for people handling bulk powder or concentrated ketamine every working day, a different exposure pattern from a patient taking a single prescribed troche.
Handling Your Troches at Home
Once your troches are compounded, dispensed, and labeled, the pharmacy-side controls under USP 800 have already been applied. Your role as a patient is simpler: follow your prescriber's dosing instructions and use ordinary care in how you store and handle the medication. That is separate from technique questions like sublingual versus buccal administration or knowing what do ketamine troches look like, which your pharmacy or prescriber should also walk you through.

At-Home Handling Checklist
- Wash your hands before and after handling a troche
- Keep troches in their original, labeled container
- Store them out of reach of children and pets
- Avoid unnecessary bare-hand contact; handle only what your dose requires
- Ask a pregnant or breastfeeding household member not to handle your troches directly
- Return unused or expired troches to a DEA-authorized take-back location or your pharmacy
- Ask your compounding pharmacy whether it follows USP 800 hazardous drug handling standards
Reproductive Exposure and Disposal
Because NIOSH's hazardous drug designation for ketamine relates to reproductive and developmental toxicity data, household members who are pregnant or breastfeeding should avoid directly handling your troches. Ketamine is also a Schedule III controlled substance under the Drug Enforcement Administration (DEA), so unused doses belong at a DEA-authorized take-back site or back with your pharmacy, not in household trash or a toilet. Ask your prescriber or pharmacist for guidance specific to your situation.
Key Takeaway
Key takeaway: USP 800 is a pharmacy operations standard, not a signal that your prescribed troches are unsafe to use as directed. It describes the safety controls your compounding pharmacy should already have in place before your medication ever reaches you.

Frequently Asked Questions
No. USP 800 addresses how pharmacy staff handle hazardous drugs during compounding, storage, and disposal, not the safety of taking a troche as your prescriber directs. The standard exists to protect the people preparing your medication from repeated occupational exposure.
Ask directly. A legitimate compounding pharmacy should be able to describe its hazardous drug handling procedures and any third-party accreditation it holds that reviews compliance with USP standards, including USP 800, 795, and 797.
No. USP 800 is a compounding and handling standard, unrelated to FDA product approval. Compounded ketamine troches are prescribed off-label and are not FDA-approved products; only esketamine (Spravato) holds FDA approval for treatment-resistant depression. See the FDA status of compounded ketamine troches for more detail.
Return them to a DEA-authorized drug take-back location or ask your pharmacy about a mail-back disposal option. Do not flush them or throw them in household trash, since ketamine is a controlled substance and unused doses should be tracked out of the household.
