The white oval pill featuring the imprint IP 204 is a prescription-only combination medication containing Oxycodone Hydrochloride (10 mg) and Acetaminophen (325 mg). It is a generic formulation of the well-known brand-name drug Percocet.
Because it contains oxycodone a potent opioid this medication is classified as a Schedule II Controlled Substance in the United States, meaning it carries a high potential for abuse, severe dependency, and addiction.
Pill Identification
To safely verify this medication, confirm its visual and structural parameters:
- Attribute Specification
- Imprint Code IP 204

Black Market Warning: Counterfeit pills mimicking the IP 204 imprint are frequently sold illicitly. These fake tablets are often pressed with lethal doses of illicit fentanyl. Authentic medication should only ever be obtained from a licensed pharmacy.
Mechanism of Action
The IP 204 pill provides “dual-action” pain relief by attacking pain through two entirely distinct pathways in the central nervous system:
- Oxycodone (10 mg): A semi-synthetic opioid that binds directly to mu-opioid receptors in the brain and spinal cord. By activating these receptors, it inhibits the transmission of ascending pain signals and fundamentally alters how the brain perceives and emotionally responds to pain. It also induces a feeling of relaxation or mild euphoria.
- Acetaminophen (325 mg): A non-opioid, non-salicylate analgesic. It works primarily by inhibiting prostaglandin synthesis within the central nervous system, effectively raising the body’s overall pain threshold and reducing fever.
Combined, these two agents create a synergistic effect, offering significantly stronger pain control than either drug could provide on its own.
Dosage and Administration
This medication is strictly indicated for the management of acute, short-term moderate to severe pain when non-opioid options (like ibuprofen or plain acetaminophen) are insufficient or cannot be tolerated.
- Standard Adult Dosing: Typically, 1 tablet every 6 hours as needed for pain.
- Administration: Can be taken with or without food. Taking it with food or a glass of milk may help mitigate opioid-induced nausea.
- Maximum Daily Ceiling: Because each pill contains 325 mg of acetaminophen, individuals must ensure they do not exceed 4,000 mg of acetaminophen daily from all medication sources to avoid permanent liver damage. Additionally, dosing must be carefully managed to prevent opioid toxicity.
Severe Boxed Warnings & Precautions
The FDA places its most severe warnings (Boxed Warnings) on this combination due to the inherent risks of opioid components:
Addiction, Abuse, and Misuse
Even when taken exactly as directed by a doctor, physical dependence and addiction can develop within just a few weeks of consistent use. Never crush, chew, snort, or dissolve the tablet, as this releases the entire dose of oxycodone rapidly, drastically increasing the risk of a fatal overdose.
Life-Threatening Respiratory Depression
Oxycodone slows down brain activity, which can dangerously depress the respiratory drive. Breathing can slow down to shallow, irregular rates or stop entirely. This risk is highest when first starting the medication or following a dose increase.
Fatal Drug Interactions (CNS Depressants)
Taking the IP 204 pill alongside other Central Nervous System (CNS) depressants can cause profound sedation, respiratory arrest, coma, and death. Never mix this medication with:
- Alcohol
- Benzodiazepines (e.g., Xanax, Valium, Ativan)
- Muscle relaxants or prescription sleep aids
Severe Liver Warning
Acetaminophen overexposure can cause acute liver failure. Avoid taking any other cold, sinus, or sleep over-the-counter medications that contain “APAP” or acetaminophen while using this prescription.
Potential Side Effects
Side effects are common and generally scale with the dosage size. They are typically split between the gastrointestinal tract and the nervous system.
Common Side Effects
- Constipation: Opioids slow down bowel motility. Doctors frequently recommend a stool softener alongside treatment.
- Nausea and Vomiting: Especially common during the first few doses.
- Dizziness, Drowsiness, and Lightheadedness: Impairs the physical and mental abilities required to drive or operate heavy machinery.
- Dry mouth and sweating
Serious Side Effects (Require Immediate Emergency Care)
- Extreme somnolence (inability to wake up or stay awake)
- Slowed, shallow, or labored breathing
- Pinpoint (severely constricted) pupils
- Cold, clammy, or bluish skin (cyanosis)
- Severe allergic skin reactions (such as blisters or peeling skin from acetaminophen allergy)
Discontinuing the Medication
If this medication has been used daily for more than one to two weeks, do not stop taking it suddenly. Abruptly halting an opioid can precipitate severe, distressing physical withdrawal symptoms, including extreme anxiety, rapid heart rate, tremors, severe muscle aches, sweating, diarrhea, and vomiting. Always consult your prescribing doctor to establish a gradual, safe tapering schedule.
