What Medication Is Associated With The 230 Yellow Round Pill?

Color, shape, and imprint are the three data points used to identify an unknown prescription pill. A yellow, round pill with the imprint “230” or “C 230” most commonly refers to one of two opioid medications: Acetaminophen and Oxycodone Hydrochloride (sold under brand names including Percocet, Endocet, and Roxicet) or Oxymorphone Hydrochloride Extended-Release (formerly sold as Opana ER). Other medications share a similar appearance, so identification should always be confirmed using a verified pill identifier or by consulting a pharmacist or physician.

If you did not receive this pill directly from a licensed pharmacy with a valid prescription, do not take it. Counterfeit pills that mimic the appearance of prescription opioids are widely available and may contain unknown substances, including fentanyl.

All Medications That Match the 230 Yellow Round Pill Description

According to Drugs.com, the following medications match a yellow, round pill with the imprint “230”:

• Acetaminophen and Oxycodone Hydrochloride (C 230 imprint): 325 mg / 10 mg. Sold under brand names Percocet, Endocet, Nalocet, Primlev, Roxicet, and Xartemis XR. A Schedule II controlled opioid analgesic.
• Oxymorphone Hydrochloride Extended-Release: 40 mg. Formerly sold as Opana ER. A Schedule II opioid. The extended-release formulation was withdrawn from the U.S. market at the FDA’s request in 2017.
• Ethinyl Estradiol and Norgestimate: 0.035 mg / 0.215 mg. An oral contraceptive tablet.
• Bisacodyl: 5 mg. A stimulant laxative.
• Trandolapril: 2 mg. An ACE inhibitor used to treat high blood pressure and heart failure.

The two opioid entries, Percocet (C 230) and Opana ER, carry the highest risk and are the most clinically significant matches. The sections below cover each in detail.

Acetaminophen and Oxycodone Hydrochloride (Percocet C 230)

Percocet is a combination prescription medication that pairs oxycodone, an opioid analgesic, with acetaminophen, a non-opioid pain reliever and fever reducer. The C 230 formulation contains 10 mg of oxycodone and 325 mg of acetaminophen. It is prescribed for moderate-to-severe pain when non-opioid alternatives have not provided adequate relief.

Oxycodone is classified as a Schedule II controlled substance by the Drug Enforcement Administration, meaning it carries a high potential for misuse, dependence, and addiction. It works as a central nervous system (CNS) depressant, binding to opioid receptors in the brain and spinal cord to reduce the perception of pain. According to the FDA, immediate-release oxycodone formulations are approved for moderate-to-severe pain in patients for whom alternative treatments are inadequate. Extended-release formulations are reserved for patients requiring continuous, around-the-clock pain management.

Side Effects of Acetaminophen and Oxycodone Hydrochloride

As a CNS depressant, oxycodone is associated with a range of adverse effects. Common and serious side effects include:

• Constipation and gastrointestinal distress
• Nausea and vomiting
• Dizziness and sedation
• Dry mouth
• Headache
• Sweating
• Slow or irregular heartbeat
• Low blood pressure
• Skin rashes
• Hallucinations and irritability
• Seizures
• Respiratory depression (slowed or stopped breathing, a potentially fatal effect)

Respiratory depression is the primary cause of opioid overdose death. If someone taking oxycodone becomes unresponsive, is breathing very slowly, or cannot be woken, call 911 immediately.

Does Oxycodone Cause Addiction?

Yes. Oxycodone and other opioid medications alter the brain’s reward and pain-regulation systems with repeated use. According to the National Institute on Drug Abuse (NIDA), long-term opioid use produces functional and structural changes in the brain that make it increasingly difficult to stop use despite harmful consequences. This is the clinical definition of opioid use disorder (OUD). Dependence can develop even when the medication is taken exactly as prescribed, which is why opioid prescriptions are closely monitored and typically limited in duration.

Oxymorphone Hydrochloride Extended-Release (Opana ER)

Oxymorphone is a synthetic opioid derived from morphine. In its oral form, oxymorphone can be significantly more potent than morphine, making it one of the stronger opioid analgesics that was available by prescription. Like oxycodone, it is a Schedule II controlled substance and a CNS depressant that acts on opioid receptors to reduce the experience of severe chronic pain. It was also used as a pre-operative sedative.

The 40 mg extended-release formulation, sold as Opana ER, was withdrawn from the U.S. market in 2017 after the FDA determined that its risks, including a pattern of misuse involving injection of crushed tablets, outweighed its benefits. The drug is no longer legally manufactured in the United States, but it may still be obtained illicitly.

Side Effects of Oxymorphone Hydrochloride

Oxymorphone shares many of the same adverse effects as other opioid medications. Side effects include:

• Blurred vision
• Respiratory changes, including slowed or labored breathing
• Confusion and disorientation
• Chest tightness
• Headache
• Dry mouth and increased thirst
• Urinary retention
• Lightheadedness
• Rapid heart rate
• Sweating
• Swollen extremities
• Fatigue

The FDA has issued warnings that serious, life-threatening, and potentially fatal respiratory depression can occur with oxymorphone extended-release, particularly when the tablet is misused by crushing, chewing, dissolving, or injecting it. Misuse of this kind causes the full 40 mg dose to be absorbed rapidly, which can result in a fatal overdose.

Does Oxymorphone Cause Addiction?

Yes. All full opioid agonists carry a risk of misuse, dependence, and addiction. Oxymorphone’s high potency makes this risk particularly significant. Even though the Opana ER formulation has been discontinued, oxymorphone obtained illicitly remains in circulation and continues to be misused. The same neurological changes that occur with oxycodone use apply to oxymorphone: repeated exposure alters brain function in ways that drive compulsive use.

Could the 230 Yellow Round Pill Be a Counterfeit?

This is a serious and increasingly common concern. The FDA requires that all prescription medications carry unique identification markers, including imprint codes, to support accurate dispensing and patient safety. Counterfeit pill manufacturers often replicate these markers to make fake pills appear legitimate.

The danger is in what counterfeit pills actually contain. Because they are produced outside of regulated pharmaceutical manufacturing, the active ingredients and their quantities are unknown. The Drug Enforcement Administration (DEA) has reported that a significant proportion of counterfeit pills tested in recent years contain fentanyl, and that many of those contain a potentially lethal dose. A pill that looks identical to a C 230 Percocet tablet may contain fentanyl, methamphetamine, or an uncontrolled quantity of oxycodone.

Safe prescription medications are dispensed only through licensed pharmacies with a valid prescription from a licensed prescriber. If a pill was obtained through any other channel, it should be treated as potentially counterfeit and not ingested. If you are unsure, bring the pill to a pharmacy, a healthcare provider, or a law enforcement agency for identification.

How to Identify a Pill You Are Unsure About

The most reliable free tool for pill identification is the pill identifier available at Drugs.com. Enter the imprint exactly as it appears on the pill (for example, “C 230”), along with the color and shape, to see all possible matches with images. You can also search by the drug name you believe the pill to be and compare images.

If the online tool does not resolve your question, take the pill to a pharmacist. Pharmacists are trained in medication identification and can confirm or rule out a match at no cost. If you suspect the pill is counterfeit or was obtained illegally, contact a law enforcement agency or a healthcare provider.

Signs of Opioid Use Disorder

Opioid medications prescribed for legitimate pain management can lead to dependence and addiction even when used as directed. Opioid use disorder (OUD) is a chronic medical condition, not a personal failing. Recognizing the signs is the first step toward getting help.

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, signs of opioid use disorder include:

• Persistent cravings for opioids
• Preoccupation with obtaining, using, or recovering from opioids
• Inability to control or reduce opioid use despite wanting to
• Continuing to use opioids despite negative consequences at work, in relationships, or to physical health
• Withdrawal symptoms when opioid use is reduced or stopped
• Needing increasingly higher doses to achieve the same effect (tolerance)
• Using opioids in situations where it is physically dangerous

If you recognize these signs in yourself or someone you care about, treatment is available and effective. Opioid use disorder responds well to evidence-based treatment, including medically supervised detox, residential care, and medication-assisted treatment (MAT).
