Key takeaway
Expired or leftover medicines in the house are a risk to children, pets, and anyone looking for pills. The FDA says the best disposal option is a drug take-back location or a prepaid mail-back envelope; if neither is available, check the FDA flush list, and otherwise mix medicines with dirt or cat litter before trashing them.

If you're cleaning out a medicine cabinet because a pill bottle was where it shouldn't have been — in a teenager's backpack, a guest's coat pocket, or your own hand for reasons you didn't plan — this page is for you. Getting old medicines out of the house is one of the few household tasks that measurably reduces risk, and it takes less than an afternoon.
The safest way to dispose of most unused or expired medicines is a drug take-back location or a prepaid mail-back envelope, according to FDA. DEA's collection site locator at dea.gov/takebackday shows sites near your zip code, and its National Take Back Day events add temporary collection points nationwide. If take-back isn't available: flush medicines only if they are on the FDA flush list; otherwise mix them with dirt, cat litter, or coffee grounds, seal the mixture in a bag, and put it in the trash with personal information scratched off the label.
Why Leftover Medicines Are a Household Risk
FDA's disposal guidance names the risks plainly: unused medicines taken by someone they weren't prescribed for, accidentally taken by a child or pet, or taken dangerously other than as directed. FDA's own video on the subject notes where these medicines actually live — bathrooms, kitchens, bedrooms, purses, and anywhere you store medicines — which is worth sitting with for a second. The riskiest bottle in your house may be in a purse on the floor.
There's also the diversion angle. Pills that linger "just in case" are available to anyone in the house or visiting it, including people struggling with an opioid or other substance use disorder. If a bottle you remember as full is suddenly half empty, that is a signal worth acting on, not ignoring. This is also a prevention step: clearing the house of unneeded medications is one of the practical things families do when someone they love is at risk.
Take-Back: The Best Option
Both FDA and DEA point to take-back as the preferred route. FDA says the best way to dispose of most unused or expired medicines — prescription and over-the-counter — is a take-back location or a prepaid mail-back envelope. DEA maintains a collection site locator where you enter a zip code or county/city/state and see collection sites near you; DEA notes that sites are added daily, so check again if your first search comes up empty. Per FDA, take-back locations are often found at local pharmacies or police stations, and may offer on-site drop-off boxes, mail-back programs, or in-home disposal products.
DEA also runs National Take Back Day, a periodic nationally coordinated collection event, with results from each event published on the Take Back Day page. The event is useful, but you don't have to wait for it — permanent collection sites are listed in the same locator and accept medicines year-round.
If you have even 15 minutes tonight: open dea.gov/takebackday, enter your zip, and note the nearest site and its hours. That's the whole first step.
Mail-Back Envelopes
If getting to a site is the obstacle, FDA describes prepaid drug mail-back envelopes as an equally good option: fill the envelope with your unused or expired medicine, seal it, and take it to any United States Postal Service office or USPS drop-box. Pharmacies and take-back programs are the usual source of the envelopes, so ask your pharmacist whether they stock them.
The Flush List: When Flushing Is the Right Move
FDA keeps an official flush list of medicines it says may be especially dangerous with just one dose if taken by children, pets, or others in the home — many powerful opioids are on it, and FDA explains that flushing certain medicines such as opioids helps keep everyone safe by ensuring these drugs can't be accidentally or intentionally swallowed, touched, or misused.
The rule FDA gives cuts both ways:
- If your medicine is on the FDA flush list and no take-back or mail-back option is available, flush it immediately.
- If your medicine is not on the flush list, do not flush it. Put it in the trash using the steps below.
Check the current flush list on FDA's drug disposal pages before deciding — the list is specific, and guessing is how medicines that shouldn't be flushed end up in the water supply.
Trash Disposal, Step by Step
For medicines not on the flush list, when no take-back or mail-back option exists, FDA's instructions are concrete:
- Mix the medicine with an unappealing substance — dirt, cat litter, or used coffee grounds.
- Do not crush the pills.
- Place the mixture in a sealed plastic bag.
- Scratch out the personal information on the empty prescription label before discarding the packaging.
The point of the unappealing mixture is to make the medicine unusable if a child, pet, or person digs through the trash. The label step protects your identity and your prescriptions.
Two edge cases FDA flags: needles and syringes have their own disposal guidance (see FDA's Medication Disposal Q&A), and some products with unusual dosage forms — sprays, lozenges — have product-specific instructions on the prescription packaging or from your pharmacist.
Storage Habits That Reduce Risk
Disposal handles what you're done with; storage protects what you're still using. There's no federal standard for home storage, so the practical guidance is common sense anchored in where medicines actually end up: consolidate them into one known location instead of scattering them across the bathroom, the kitchen, and a purse; keep them out of reach of children and pets; keep an informal count of pills remaining in important prescriptions so a shortfall surfaces quickly; and dispose promptly rather than stockpiling. If the household includes opioid prescriptions, ask your pharmacist about locking storage — many pharmacies sell locking bags and boxes designed for exactly this, and some insurance plans cover them.
And a prevention note that belongs in every home with opioids: DEA's Take Back Day page explains that naloxone reverses opioid overdoses in under two minutes and that Narcan can be administered by family members or caregivers. Ask a pharmacist or doctor about keeping naloxone at home. In an overdose emergency, call 911 immediately.
If This Page Is About Someone You Love
Sometimes a medicine-cabinet cleanup is really the moment you admitted something you've been avoiding: the count doesn't add up, bottles vanish, or someone you love is taking medication that was never theirs. If that's where you are, you don't have to sort it out alone. SAMHSA's National Helpline at 1-800-662-4357 is free, confidential, and answers 24/7 in English and Spanish — it can point you to treatment and support options for a family member without requiring any personal information. If someone is in a mental health crisis, call or text 988. In a medical emergency, call 911.

Common Questions
Where can I find a drug take-back location near me?
DEA maintains a collection site locator on its Take Back Day page at dea.gov/takebackday — enter your zip code or county/city/state and it shows collection sites near you. DEA notes that sites are added daily, so check back if nothing shows up. Take-back locations are often at local pharmacies or police stations, per FDA, and may offer on-site drop-off boxes, mail-back programs, or in-home disposal products.
What is DEA National Take Back Day?
It is DEA's periodic, nationally coordinated event where communities collect unused prescription drugs at temporary sites. The National Take Back Day results page on dea.gov/takebackday tracks each event. If you miss the event, permanent year-round collection sites are listed in the same locator — disposal doesn't have to wait for the next scheduled day.
Which medicines should I flush, and which should I throw in the trash?
FDA keeps a flush list of specific medicines that may be especially dangerous with just one dose if taken by children, pets, or others — many opioids are on it. FDA says flush those immediately if a take-back or mail-back option isn't available, and never flush anything not on the list. Other medicines go in the trash: mix with dirt, cat litter, or coffee grounds, don't crush pills, seal in a bag, and scratch out personal info on the label.
Can I use a mail-back envelope instead?
Yes. FDA describes prepaid drug mail-back envelopes as one of the best disposal options: fill the envelope with unused or expired medicine, seal it, and drop it at any USPS office or Postal Service drop-box. Some pharmacies and take-back locations provide them; check with your pharmacist.
How should I store prescription medicines at home so they don't get diverted?
FDA's own disposal video points out that unused medicines sit in bathrooms, kitchens, bedrooms, and purses — places that aren't secure. Sensible practices follow directly from that: keep medicines in one known location, out of reach of children and pets, track how many pills should be left so you notice a shortfall, and get rid of what you're no longer using promptly. If someone in the house takes an opioid medication, ask your pharmacist about lock bags or lockboxes.
What about naloxone and overdose safety at home?
DEA's Take Back Day page describes naloxone as a medication that can reverse an opioid overdose in less than two minutes and says Narcan can be administered by family members or caregivers. If your household contains opioid medicines, ask a pharmacist or doctor about having naloxone on hand. In an actual overdose emergency, call 911 immediately.
