Found a loose pill? It’s a mini heart attack moment. You're staring at this tiny, chalky thing—white, round, and stamped with a simple ML—and your brain immediately goes to the worst-case scenario. Is it a heavy-duty painkiller? Someone’s lost blood pressure med? Honestly, the "ML" imprint is one of those confusing ones because it doesn't just belong to one single drug.
Context is everything here. Depending on whether there are numbers next to those letters, you could be holding anything from a homeopathic leg cramp remedy to a potent prescription antipsychotic. Let's peel back the layers on what this mystery pill actually is before you do anything risky.
The Most Common Culprit: Homeopathic Relief
If the pill is just a plain, small, white round tablet with ML and absolutely no numbers, there is a very high statistical chance you're looking at a homeopathic product. Specifically, these are often manufactured for The Magni Company or Apotheca Company.
They aren't "drugs" in the way we usually think of them. They’re basically ultra-diluted natural substances used for:
- Muscle and Leg Cramp Relief: Contains stuff like Magnesia phosphorica and Cuprum metallicum.
- Sleep Assistance: Often uses Chamomilla or Passiflora.
- Sciatica or Tinnitus Relief: Same tiny white format, different botanical "actives."
Because these are homeopathic, they usually contain a lot of lactose or magnesium stearate as filler. If you're lactose intolerant, even these "natural" pills might give you a stomach ache. But compared to a prescription narcotic, they are physically quite harmless.

When Numbers Change the Game
Now, if that ML has a number tailing it, the stakes go up. Pharmaceutical companies like MSN Laboratories or Novadoz Pharmaceuticals use the ML prefix for some serious heavy-hitters.
ML 40: Lurasidone Hydrochloride
This is a big one. ML 40 is the imprint for Lurasidone (40 mg), better known by the brand name Latuda. It’s an atypical antipsychotic. Doctors prescribe this for schizophrenia or the depressive episodes associated with Bipolar I disorder.
If you or someone you know takes this, it’s not something to mess around with. Skipping a dose or taking one by mistake can cause significant side effects like extreme drowsiness, tremors, or "inner restlessness" (akathisia). It’s definitely not a "chill pill."
ML 60 and ML 61: Escitalopram
Sometimes you'll see ML 60 or ML 61. These are often versions of Escitalopram, which is the generic for Lexapro.
- ML 60: Usually 10 mg.
- ML 61: Usually 20 mg.
It’s an SSRI used for anxiety and depression. While it’s widely prescribed, stopping it cold turkey can lead to "brain zaps" and a nasty withdrawal syndrome.

ML 11: Liothyronine Sodium
This tiny white round pill is used for thyroid hormone replacement. If someone has an underactive thyroid (hypothyroidism), this provides a synthetic version of the T3 hormone. It’s powerful stuff; too much can make your heart race like you’ve had ten espressos.
Is It Oxycodone?
This is the question that keeps pharmacists up at night. People see a small white round pill and panic, thinking it’s a "Percocet" or "oxy."
The short answer: No. Pure oxycodone or oxycodone/acetaminophen blends usually have very different imprints like M30, 512, RP, or A349. While there are dozens of manufacturers, an "ML" alone is not a standard marking for American-made oxycodone. However—and this is a huge however—we live in an era of counterfeits. Illegal labs can press anything into a pill. If you didn't get that pill directly from a pharmacy bottle, you cannot trust the imprint 100%.
Why Imprints Even Exist
The FDA basically mandates that every legal solid oral medication has a unique "ID badge." This is for safety. If a kid gets into a cabinet or an ER doctor needs to identify what a patient swallowed, they shouldn't have to guess.
The "ML" generally stands for the manufacturer's internal code or the lab that produced the generic version. When a drug goes off-patent, a dozen different companies might start making it, each with their own "ML," "IP," or "GG" stamp. It’s a mess for the consumer, but it’s how the industry tracks quality and origin.
What You Should Do Right Now
If you found an ML white round pill and you're not sure what it is, don't play chemist.

- Don't Taste It: Some people think they can identify pills by bitterness. That's a myth and can be dangerous with high-potency meds like Lurasidone.
- Use a High-Res Photo: Take a clear picture of the imprint and use a professional pill identifier like the one on Drugs.com or WebMD.
- Call the Pro: Take the pill to any local CVS, Walgreens, or independent pharmacy. A pharmacist can look at the bevel, the thickness, and the font of the "ML" and tell you exactly what it is in seconds.
- Dispose of It Safely: If it’s a stray pill, don't just toss it in the trash where a pet might find it. Mix it with coffee grounds or kitty litter in a sealed bag before throwing it out, or better yet, take it to a drug take-back kiosk.
Identifying a pill is only the first step. If you realized you've taken the wrong medication, call Poison Control (1-800-222-1222) immediately. Even if it's "just" a homeopathic pill, getting a professional opinion is the only way to be sure you're safe.
