Found an Unknown Pill? Here's Exactly What to Do

You find a loose pill — in a child's bedroom, on the bathroom floor, at the bottom of a bag, or mixed in with other medications — and you have no idea what it is. Finding an unknown pillis more common than most people realize, and more dangerous than it looks. The wrong move can put someone's health at risk. Here is the safest, step-by-step approach to handle it.

Step 1: Do not take it — and do not throw it away

The first rule when you find an unknown pill is simple: do not take it, and do not let anyone else take it either. A pill that looks familiar can still be the wrong drug, the wrong dose, or a counterfeit that contains something entirely different from what the stamp suggests.

Equally important: do not throw the pill away yet. You may need it — to show a pharmacist, to describe it to Poison Control, or to compare against an identification result. Set it somewhere safe and out of reach of children and pets while you work through the steps below.

Step 2: Record every physical detail

Before you do anything else, write down everything you can observe about the pill. The more detail you capture now, the faster the identification process will go. Note:

• Color.Be specific — “light blue” vs. “teal,” “off-white” vs. “cream.”
• Shape. Round, oval, capsule, oblong, diamond, triangle, or another shape.
• Size. Estimate in millimeters or compare it to a coin — for example, roughly the diameter of a pencil eraser.
• Imprint. Any letters, numbers, or symbols stamped or embossed on either side (check both).
• Score line. A groove designed for splitting the pill in half.
• Coating and texture. Glossy film coat, matte surface, or gel capsule with powder inside.
• Where you found it. Context narrows options quickly.

Step 3: Look for an imprint under bright light

In the United States, the FDA requires almost all approved prescription and over-the-counter tablets and capsules to carry an imprint code — letters or numbers stamped into the pill. Tilt the pill under a bright light (a phone flashlight works well) and inspect both faces and the edge. Faint, shallow, or partially worn imprints are easy to miss at a glance.

If you find an imprint, note it exactly as it appears. Databases like the one at Drugs.com or the FDA's Pillbox let you enter a code and filter by color and shape to get a match.

If there is no imprint, you are dealing with a different situation — likely a supplement, a foreign or compounded medication, or something illicit. Our guide to identifying a pill with no imprint covers that scenario in depth.

Step 4: Use a photo-based pill identifier

Whether or not the pill has a visible imprint, a photo-based AI identifier can give you a useful starting point. Unlike traditional databases that require you to type in an imprint code, a photo app analyzes the pill's actual appearance — color, shape, size, and any markings — and returns a ranked list of likely matches, each with a confidence score.

To get the best result:

• Place the pill on a plain, contrasting background (white paper on a dark table, or vice versa).
• Use natural or bright indoor light — avoid flash glare.
• Take a sharp, in-focus photo of both sides of the pill.
• Include something for scale if the size is unusual.

The result is a shortlist — not a definitive answer. A good AI identifier will show a confidence score and tell you when it isn't sure rather than presenting a single result as fact. Treat it as information to bring to the next step.

Step 5: Confirm with a pharmacist

A pharmacist is the most reliable resource for identifying an unknown pill. They can match it by physical description or photo, cross-check it against your household's medication records, and tell you definitively whether it is safe. This step is free, fast — most pharmacies will help you at the counter without an appointment — and the only step that ends in certainty.

Bring the actual pill if you can, along with the photo and notes you took in the earlier steps. The more information the pharmacist has, the faster and more accurate the identification will be.

Step 6: Dispose of unidentified pills safely

If you cannot positively identify the pill and have no safe use for it, dispose of it properly. Do not flush most medications down the toilet (the FDA maintains a list of medications safe to flush, but most are not on it). Instead:

• Take it to a DEA-authorized take-back location — most pharmacies and many police stations accept medications, no questions asked.
• Use an at-home disposal kit (available at most pharmacies) that neutralizes the medication before you throw it in the trash.
• If no other option is available, mix the pill with something undesirable (coffee grounds or dirt) in a sealed bag before placing it in household trash.

What makes found pills especially risky right now

The rise of counterfeit pills has made finding an unknown pill more dangerous than it was even five years ago. Fake pills pressed to look like legitimate brand-name medications — Xanax, Adderall, OxyContin — often contain illicitly manufactured fentanyl, a synthetic opioid 50 to 100 times more potent than morphine. A single pill that looks unremarkable can be lethal.

This is not a reason to panic, but it is a reason to treat every unknown pill as potentially serious and to confirm the identification before making any decisions about it.
