Many search for an M523 pill identifier for various reasons. Some people are concerned if the white oval pill they’ve found is real or a pressed counterfeit. Others may be worried after finding the pill in their loved one’s possession, wondering if they are misusing or abusing it.

What is M523 Pill?

The M523 pill is a white, oval tablet imprinted with “M523” on one side and “10/325” on the other. Manufactured by Mallinckrodt Pharmaceuticals, it contains 325 mg of acetaminophen and 10 mg of oxycodone hydrochloride (Oxy). Also known as Perc 10 or Oxy 10, the M523 white pill is a prescription-only narcotic with a high potential for addiction. It is classified as a Schedule II controlled substance. Counterfeit versions are commonly found on the street, the dark web (DW), and online platforms, posing serious health risks.

Individuals might search for this medication using various terms like:

  • M523 Oblong Pill
  • M523 Oval Pill
  • M523 Oxy 10 325
  • M523 on one side 10 325

M523 white oval pill is often prescribed under brand names such as Percocet, Endocet, Roxicet, and Primalev. It is commonly used to manage:

  • Chronic pain
  • Post-operative pain
  • Back pain
  • Joint pain
  • Cancer-related pain

The pill has “M523” imprinted on one side and “10/325” on the other, making it easily identifiable.

What Is In M523 White Pill?

The M523 pill is commonly known as Percocet, which contains oxycodone and acetaminophen. Some people mistakenly confuse it with Hydrocodone, Norco 10, or Vicodin (Vikes) because these also combine opioid with Tylenol.

Oxycodone Hydrochloride: An opioid pain reliever, oxycodone is the primary ingredient responsible for the pain-relieving effects of this medication.

Acetaminophen: Commonly known by the brand name Tylenol, acetaminophen is a less potent pain reliever that enhances the effects of oxycodone.

Risk and Dangers of M523 Pills

10/325 Pill: Acetaminophen Risk

M523 10/325 pill contains 325 mg of acetaminophen (Tylenol) with 10 mg of oxycodone. While 325 mg may seem low, taking multiple pills or combining it with other acetaminophen-containing drugs can cause liver damage or death. The risk increases if you:

  • Take more than 4,000 mg of acetaminophen per day.
  • Consume alcohol while taking 10/325 Percocet pill.

According to the research on National Library of Medicine:

  • 56,000 ER visits, 2,600 hospitalizations, and 500 deaths annually in the U.S. are due to acetaminophen toxicity.
  • 50% of these cases are unintentional overdoses.
  • Acetaminophen toxicity is the leading cause of liver transplants in the U.S.

M523 Addiction and Dependence

Oxycodone, the active opioid in the M523, is highly addictive. Regular use can quickly lead to dependence, even if taken as prescribed. For some, addiction can begin within a few weeks of regular use.
How you become dependent on M523:

  • Tolerance develops, meaning the same dose provides less relief, leading to the need for higher doses.
  • Withdrawal symptoms may occur if you stop using the pill, such as nausea, anxiety, sweating, and restlessness.

How M523 makes you feel:

  • Initial effects of M523 white oval pill include pain relief, feelings of relaxation, and euphoria.
  • Over time, users may experience drowsiness, confusion, and mood swings.

Long-term use of M523 can lead to severe physical dependence and addiction, requiring medical intervention for safe withdrawal.

Withdrawal Symptoms from M523 Pill

Even if used as prescribed, long-term use of the M523 pill can lead to dependence. Stopping the medication abruptly can cause withdrawal symptoms such as:

  • Nervous tremors
  • Sweating
  • Runny nose
  • Muscle spasms
  • Anxiety and restlessness

In severe cases, withdrawal from the M523 white pill can lead to life-threatening complications like seizures and cardiac arrest. To avoid these risks, it’s essential to taper off the medication under medical supervision.

Signs of M523 Pill Misuse or Abuse

If you find an M523 pill in a loved one’s possession, you may be concerned about misuse or abuse. Watch for signs such as:

  • Sudden mood swings
  • Pinpoint pupils
  • Drowsiness
  • Missing prescriptions
  • Social withdrawal

If you notice these signs, it’s important to approach your loved one with care and encourage a conversation about potential abuse or dependence.

Overdose Risk

If you find M523 pills in a loved one’s possession or are misusing them yourself, be aware that addiction can develop quickly. Tolerance builds, leading to increased dosages, which increases the risk of overdose.

What to Do in Case of an M523 Pill Overdose

Signs include: Slowed breathing, extreme drowsiness, cold, clammy skin, and loss of consciousness.

Administer naloxone (if available) and call emergency services immediately.

Naloxone can temporarily reverse the effects of an opioid overdose, but medical help is still necessary.

Is the M523 Pill Real or Pressed?

A significant concern in online discussions is whether the M523 pill is real or a pressed counterfeit. Users on Reddit and other platforms often describe counterfeit pills that look identical to the real white oval pill M523, but upon closer inspection, subtle differences in the size or imprint become apparent. Some counterfeit pills, referred to as “pressies,” are made to resemble legitimate Percocet but may contain fentanyl.

One user explained:
“I’ve run into multiple fake M523s. They look perfect, but some have the numbers ’10/325′ upside down. I’ve also seen skinny, long batches that didn’t feel right.”

Another user shared:
“I saw a vendor selling pressed Perc 10s for $300. They looked almost real, but I wouldn’t trust them. Fentanyl is everywhere, and nobody would test a pill they think is real.”

Counterfeit M523 pills are highly dangerous because they often contain fentanyl, commonly referred to as “fet” or “fetty,” a synthetic opioid far more potent than oxycodone.

Always buy pills from legitimate pharmacies. If you are dependent on opioid painkillers, get help before they claim your life.

Risk of Counterfeit M523 Pills

Counterfeit M523 pills, often laced with fentanyl or fentanyl analogs, are becoming widespread. These fake pills, marked “10/325” and “M523,” are nearly identical to the real ones but can be lethal due to the presence of potent substances like fentanyl, even in small amounts.

Fentanyl test strips can detect fentanyl, but they miss other dangerous substances commonly found in counterfeit pills, such as:

If you suspect a pill is counterfeit, avoid handling it and contact emergency services immediately.

In 2022, the Dutchess County Drug Task Force seized counterfeit M523 pills containing fentanyl, underscoring the growing threat of these dangerous fake pills.

Identifying Fake M523 Pills

To determine whether an M523 pill is real or fake, check for the following:

  • Clear imprints: Real pills should have “M523” on one side and “10/325” on the other.
  • Consistent size and shape: Real pills are uniform, while counterfeit pills may vary in size or thickness.
  • Taste difference: Authentic M523 pills contain acetaminophen, which has a slight taste. If the pill tastes off, it may be counterfeit.

Keep in mind that while checking these features can provide clues about the legitimacy of a pill, it is not foolproof.

How to Safely Stop Taking the M523 Pill

If someone is dependent on the M523 white oval pill, tapering off under medical supervision is the safest method. Gradually reducing the dose can help minimize withdrawal symptoms and prevent severe complications. It’s essential to consult a healthcare provider before discontinuing the pill.
