The safest way to dispose of Tylenol is to drop it off at a drug take-back location. If that’s not an option, you can throw it in the household trash after mixing it with something unappetizing like dirt or used coffee grounds. Tylenol (acetaminophen) is not on the FDA’s flush list, so it should never go down the toilet or sink.
Best Option: Drug Take-Back Programs
Permanent drug take-back collection sites exist at many pharmacies, hospitals, and law enforcement offices across the country. The DEA maintains a search tool at apps.deadiversion.usdoj.gov where you can enter your zip code and find the nearest year-round drop-off location within 5 to 50 miles. Many chain pharmacies like CVS, Walgreens, and Walmart host collection bins near their pharmacy counters.
The DEA also holds National Prescription Drug Take Back Days twice a year, typically in April and October. These events set up temporary collection sites in communities that may not have permanent ones. You can bring Tylenol, other over-the-counter medications, and most prescription drugs with no questions asked.
How to Dispose of Tylenol in Household Trash
If you can’t get to a take-back site, the FDA recommends a specific process for throwing Tylenol away at home. Don’t just toss the bottle in the garbage, where a child or pet could find it. Follow these steps:
- Remove the pills or liquid from the original container. Take everything out of the bottle.
- Mix with something unappetizing. Combine the medication with dirt, cat litter, or used coffee grounds. This discourages anyone from retrieving it. If you’re disposing of liquid Tylenol, mix it the same way. Do not crush tablets or capsules before mixing.
- Seal it up. Place the mixture in a sealed plastic bag or another container that won’t leak.
- Throw the sealed container in your regular household trash.
- Handle the empty bottle. Scratch out or peel off any personal information on the prescription label before recycling or trashing the empty packaging.
This process works the same for all forms of Tylenol: regular tablets, extra strength caplets, liquid gels, children’s liquid suspension, and infant drops. The key difference with liquid formulations is simply that the mixture will be wetter, so make sure your sealed bag has no holes.
Why You Shouldn’t Flush It
The FDA maintains a “flush list” of medications that are so dangerous if accidentally ingested (particularly opioids) that flushing is considered safer than leaving them in the trash. Acetaminophen is not on that list. It doesn’t carry the same risk of fatal overdose from a single accidental dose that would justify sending it into the water supply.
Flushing any medication introduces it into wastewater systems. The U.S. Geological Survey has detected acetaminophen at low levels in surface water and treated wastewater. A Minnesota Department of Health review found acetaminophen in untreated drinking water at a concentration of 0.010 parts per billion. While that’s a tiny amount, lab studies show acetaminophen can interfere with embryonic development, reproduction, growth, and endocrine function in fish. Those effects were observed at higher concentrations than what’s currently found in waterways, but there’s evidence that exposure to low-level chemical mixtures containing acetaminophen may still harm aquatic life. Keeping it out of the drain is a simple precaution.
What About Expired Tylenol
If the reason you’re disposing of Tylenol is that it’s expired, you can follow the same steps above. Expired acetaminophen doesn’t become toxic. It gradually loses potency over time as its chemical composition shifts. For minor aches and pains, an over-the-counter medication that expired a couple of months ago is generally still fine to use until you can replace it, according to University Hospitals. But if your bottle is years past its date, or you simply want to clear it out, treat it like any other unused medication and use a take-back program or the household trash method.
Disposing of Large Quantities
If you’re cleaning out a medicine cabinet and have multiple bottles of Tylenol or other medications, a take-back site is the most practical route. Mixing large amounts of pills with coffee grounds gets messy fast, and collection programs are designed to handle bulk disposal safely. Call your local pharmacy ahead of time to confirm they accept walk-in drop-offs, since some locations have quantity limits or specific hours for their collection bins.
