Frequently Asked Questions
Correct troche storage and handling means keeping ketamine troches at a controlled room temperature, away from moisture, light, and heat sources, in their original opaque packaging, while tracking your remaining supply closely because ketamine is a Schedule III controlled substance. A troche is a compounded medicated lozenge that dissolves in the mouth for buccal or sublingual absorption; you can read more about how they're formulated in our guide to how troches are made. Because troches are compounded rather than manufactured on a factory line and sealed in blister packs, they can be more sensitive to environmental conditions than many commercially produced medications. Following your pharmacy's specific label instructions, along with the general guidance below, helps each dose deliver the intended amount of medication consistently throughout treatment.
Quick Answer
Store ketamine troches at controlled room temperature, generally 20-25°C (68-77°F), in their original opaque, moisture-resistant container. Keep them away from bathrooms, kitchens, direct sunlight, and hot cars, and never use a troche that has melted, softened, or changed color or texture without checking with your pharmacy first. Because ketamine is a Schedule III controlled substance, keep an accurate count of your supply and request refills before you run low. If your pharmacy's label gives different instructions, such as refrigeration, follow that guidance over general advice.
The United States Pharmacopeia (USP) is the nonprofit organization that sets official quality and storage standards for medications compounded and dispensed in the United States. USP General Chapter 659, which defines packaging and storage requirements for pharmaceuticals, describes controlled room temperature as 20-25°C (68-77°F), with brief excursions permitted between 15-30°C (59-86°F) during normal handling. Most compounding pharmacies dispense troches with instructions to store at room temperature, away from heat sources such as radiators, sunny windowsills, parked cars, and appliances that generate warmth.
Heat can soften a troche's base and speed up degradation of the ketamine compound. According to StatPearls, a peer-reviewed clinical reference maintained on the National Library of Medicine's NCBI Bookshelf, ketamine formulations should be stored according to the specific product or compounding instructions provided, since stability can vary by preparation. If your pharmacy's label specifies a different range, such as refrigeration for a particular formulation, follow that instruction over general guidance. For more on how storage conditions relate to expiration, see our guide to ketamine troche shelf life.
Moisture is the primary environmental threat to troche integrity. Humid environments, bathrooms where steam from showers raises humidity, and unsealed containers all expose troches to moisture that can:
- Soften the troche base and alter dissolution characteristics
- Activate degradation pathways in the ketamine compound
- Promote microbial growth in preservative-free formulations
Store troches in a cool, dry location away from bathrooms, kitchens, and other high-humidity areas. A bedroom drawer, closet shelf, or dedicated lockbox generally works better than a bathroom medicine cabinet. Keep the container tightly closed between uses, and avoid handling troches with wet hands.
Ketamine is not as light-sensitive as some medications, but prolonged exposure to direct sunlight or bright artificial light can still contribute to degradation over time. Keep troches in their original opaque pharmacy packaging, and store that packaging in a drawer, cabinet, or box away from windows and direct light sources.
Traveling With Troches
- Keep troches in their original, labeled pharmacy container when traveling; this documents the prescription for a Schedule III controlled substance.
- Avoid leaving troches in a parked car, glove compartment, or direct sunlight, where temperatures can rise well above the recommended range.
- Pack troches in carry-on luggage rather than checked bags, since cargo holds can reach temperature extremes.
- Use an insulated travel case for trips to hot or humid climates.
- Bring only the quantity needed for the trip, plus a small buffer, rather than splitting your full supply across multiple bags.
If a Troche Is Damaged or Melted
If a troche has melted, softened, changed color, or developed an unusual odor or texture, do not use it. Structural changes can mean the medication is no longer distributed evenly through the troche, so the dose you receive may not match what was prescribed. Contact your prescribing provider or compounding pharmacy before using or discarding the troche, and ask whether a replacement is appropriate. For general safety information, see our ketamine troche safety guide.
A Schedule III controlled substance is a Drug Enforcement Administration (DEA) classification for drugs with moderate to low potential for physical and psychological dependence, placed below Schedule I and II substances but still subject to specific handling expectations. Ketamine falls into this category. According to the DEA's drug scheduling information, this classification carries recordkeeping and security expectations throughout the supply chain, and patients share a practical responsibility to keep track of their own supply at home.
Know how many troches you have on hand, keep a simple log of usage, and request refills before you run out to avoid gaps in therapy. Report any discrepancies, such as missing troches or unexplained shortages, to your provider promptly. If you want guidance on structuring that conversation, see our guide on working with your provider.
Key Takeaway
Troche storage and handling comes down to three habits: keep troches cool, dry, and shielded from light in their original container; never use a troche that looks, smells, or feels different from when it was dispensed; and track your controlled substance inventory closely so refills happen before you run out.

Frequently Asked Questions
Only if your pharmacy label specifically instructs it. Repeated trips in and out of a refrigerator can introduce condensation, which reintroduces the moisture that troches are meant to avoid. Follow the storage instructions on your prescription label, since compounding formulas vary by pharmacy.
Shelf life depends on the specific compounding pharmacy's formula and the beyond-use date on your prescription label. See our guide to ketamine troche shelf life for more detail on how storage conditions affect stability over time.
Do not use it. Contact your prescribing provider or compounding pharmacy to ask about a replacement, and store the remaining supply properly going forward to prevent it from happening again.
Yes, in most cases, as long as you keep them in their original labeled container and follow standard rules for traveling with a Schedule III controlled substance. Check destination-specific regulations before international travel, and ask your provider if you have questions about a specific trip.
