Finding a loose white tablet marked “T 194” can be worrying, especially when you don’t know where it came from. The official drug label identifies it as oxycodone hydrochloride 10 mg with acetaminophen 325 mg, a prescription opioid medicine used for severe pain.
The tablet is white to off-white, capsule-shaped, 14 mm long, and plain on the reverse side. These details can support identification, though counterfeit tablets can copy the same appearance. Check the original pharmacy container or ask a pharmacist before taking an unfamiliar pill.
Emergency: suspected overdose
Call 911 if someone cannot be awakened, has slow or stopped breathing, collapses, or has a seizure. Give naloxone if available and stay with the person until help arrives.
For a possible medication or acetaminophen overdose, contact Poison Control at 1-800-222-1222, even when the person feels well.
What is the T194 pill?
T194 is a generic oxycodone and acetaminophen tablet. Each tablet contains 10 mg of oxycodone hydrochloride and 325 mg of acetaminophen.
Oxycodone is an opioid pain medicine. Acetaminophen is a non-opioid medicine that relieves pain and lowers fever. The combination is available by prescription only and is classified by the DEA as a Schedule II controlled substance.
The product is manufactured by Ascent Pharmaceuticals for Camber Pharmaceuticals.
T194 pill identification details

A pharmacy may dispense the medicine under a different NDC when another company repackages it. The imprint, ingredients, and strength should still match the labeled product.
Online pill images may not show the tablet at its physical size. Use the 14 mm measurement along with the imprint, color, shape, and reverse side when discussing the tablet with a pharmacist.
A pharmacist can compare these features with official records. Laboratory testing is needed to determine what an unknown tablet contains.
How T194 differs from T191, T192, and T193
Camber sells several oxycodone and acetaminophen strengths with similar T-series imprints.
| Imprint | Oxycodone/acetaminophen strength | General appearance |
|---|---|---|
| T 191 | 2.5 mg/325 mg | White to off-white, capsule-shaped |
| T 192 | 5 mg/325 mg | White to off-white, round and scored |
| T 193 | 7.5 mg/325 mg | White to off-white, capsule-shaped |
| T 194 | 10 mg/325 mg | White to off-white, capsule-shaped |
The first number in each strength is the amount of oxycodone. The second number is the amount of acetaminophen.
These tablets cannot be exchanged without the prescriber’s approval. Taking a higher oxycodone strength than prescribed can cause severe sleepiness, respiratory depression, overdose, or death.
Is T194 the same as Percocet 10/325?
T194 contains the same active ingredients and strength associated with Percocet 10/325. Percocet is a brand name, and T194 is a generic oxycodone and acetaminophen tablet manufactured for Camber.
Both contain:
- Oxycodone hydrochloride 10 mg
- Acetaminophen 325 mg
The tablets may look different because each manufacturer uses its own shape, color, imprint, and inactive ingredients. People sometimes call every oxycodone and acetaminophen tablet “Percocet,” though the brand and generic product names are different.
A different oxycodone and acetaminophen 10/325 tablet uses the imprint M523/10/325 and has a different appearance.
What is T194 used for?
Oxycodone and acetaminophen tablets are prescribed for pain severe enough to require an opioid when other treatments are inadequate. A prescriber may consider this medicine when non-opioid pain relievers do not control the pain or cannot be tolerated.
It may be prescribed after certain operations, serious injuries, dental procedures, or other painful conditions. The reason for using it, dose, and treatment length depend on the individual patient.
For many short-term pain conditions, an opioid may only be needed for a few days. Continued use requires regular review of pain relief, side effects, and the risk of misuse or dependence.
Is T194 an immediate-release tablet?
T194 is an immediate-release oxycodone and acetaminophen tablet. Extended-release oxycodone products have different dosing instructions and cannot be substituted dose for dose.
How does T194 relieve pain?
Oxycodone
Oxycodone binds mainly to mu-opioid receptors in the brain and spinal cord. This changes how the nervous system responds to pain.
The same action can slow breathing and cause sleepiness. These effects become more dangerous after an excessive dose or when oxycodone is combined with alcohol, sedatives, or other opioids.
Acetaminophen
Acetaminophen relieves pain and reduces fever. Its exact pain-relieving action is not fully understood, though much of its effect occurs in the central nervous system.
Acetaminophen has little anti-inflammatory action. Taking too much can seriously damage the liver.
T194 dosage and safe use
The numbers 10/325 describe the amount of medicine in each tablet. They do not tell you how many tablets are safe for you.
The product Medication Guide describes taking the prescribed dose every 6 hours as needed for pain. Your pharmacy label contains the instructions selected for your condition, health history, and prior opioid use.
Follow these precautions:
- Take the medicine exactly as prescribed.
- Do not increase the dose or take it earlier than directed.
- Contact the prescriber if the dose does not control your pain.
- Do not use another person’s prescription.
- Never share or sell the tablets.
- Use the lowest prescribed dose for the shortest required period.
- Do not stop regular use suddenly without discussing a taper.
Serious breathing problems are most likely when treatment begins or after the dose is increased. They can occur even at a prescribed dose. Contact the prescriber before changing how much you take.
Rarely, an opioid can increase pain or make normal touch painful. This is called opioid-induced hyperalgesia or allodynia. Contact the prescriber if pain becomes worse after a dose increase, new pain appears, or you become more sensitive to pain. Do not increase the dose yourself.
A 10 mg oxycodone dose may cause serious breathing problems in a person who has never taken opioids. Opioid tolerance varies, so one person’s prescription cannot be used to judge what is safe for someone else.
Can you take it with food?
Oxycodone and acetaminophen may be taken with or without food. Taking it with food may reduce nausea for some people.
Follow any food instructions printed on your pharmacy label. Avoid alcohol, including medicines or liquid products that contain alcohol.
Grapefruit and grapefruit juice may increase oxycodone levels and side effects. Ask your prescriber or pharmacist whether you should avoid them.
What should you do after a missed dose?
Many prescriptions direct patients to use this medicine only when needed. In that case, there may not be a fixed dose to miss.
If your prescription uses a schedule, follow its missed-dose instructions or ask your pharmacist. Do not double the next dose.
Can you split or crush T194?
T194 has no score line. Do not split, crush, or otherwise alter it unless your prescriber or pharmacist says it is appropriate. Snorting or injecting the tablet is misuse and can cause overdose or serious injury.
Acetaminophen and liver damage
Each tablet contains 325 mg of acetaminophen. This amount counts toward your total intake from every prescription and nonprescription product.
Acetaminophen may appear on medicine labels as “acetaminophen” or “APAP”. Tylenol is a common brand that contains acetaminophen.
It is also found in many cold, flu, headache, and sleep medicines. Taking several products without checking their ingredients can cause an accidental overdose.
The product label warns patients not to exceed 4,000 mg of acetaminophen from all sources in 24 hours. This is a label limit, not a personal target. People with liver disease or regular alcohol use may need a lower acetaminophen limit. Ask a clinician which daily limit applies to you.
Do not convert the 4,000 mg limit into a permitted number of T194 tablets. Your prescribed oxycodone limit may be far lower.
Signs of possible liver injury
Possible symptoms include:
- Nausea or vomiting
- Loss of appetite
- Heavy sweating
- Upper abdominal pain
- Unusual tiredness
- Dark urine
- Yellow skin or eyes
Serious liver injury may not become clear for 48 to 72 hours after an overdose. Contact Poison Control or seek medical care immediately after a suspected excessive dose, even when no symptoms are present.
Common side effects
Common or reported side effects of oxycodone and acetaminophen include:
- Constipation
- Nausea
- Vomiting
- Drowsiness
- Dizziness or lightheadedness
- Tiredness
- Headache
- Abdominal discomfort
- Itching
Rise slowly after sitting or lying down because the medicine can lower blood pressure and cause fainting.
Constipation is common during opioid treatment. Drinking enough water, eating fiber, and staying active may be useful when these steps are safe for you. A pharmacist or prescriber may recommend a laxative when needed.
Avoid driving, operating machinery, or doing another dangerous activity until you know how the medicine affects you.
Serious side effects
Get urgent medical help for:
- Slow, shallow, or irregular breathing
- Extreme sleepiness
- Difficulty waking
- Fainting
- Severe confusion
- Chest pain
- Fast heartbeat
- Swelling of the face, tongue, mouth, or throat
- Trouble swallowing or breathing
- Seizure
- Severe abdominal pain
- A serious or spreading skin reaction
Opioids may rarely contribute to serotonin syndrome when combined with certain medicines. Symptoms can include agitation, confusion, a high body temperature, sweating, stiff muscles, poor coordination, diarrhea, or a fast heartbeat.
Opioids can cause central sleep apnea and low oxygen during sleep. Tell the prescriber about pauses in breathing, worsening sleep apnea, or unusual daytime sleepiness.
Opioids can rarely cause adrenal insufficiency, more often after longer than 1 month of use. Symptoms may include ongoing nausea, vomiting, loss of appetite, weakness, unusual tiredness, dizziness, or low blood pressure.
Acetaminophen can cause rare, serious skin reactions. Stop taking the medicine and seek medical care at the first sign of a new rash or skin reaction, including blistering, peeling skin, mouth sores, or facial swelling.
Call 911 for breathing problems, extreme drowsiness, loss of consciousness, seizure, or severe allergic symptoms.
T194 overdose signs
An overdose can result from oxycodone, acetaminophen, or both ingredients. Each causes a different form of poisoning.
Signs of an oxycodone overdose
Possible signs include:
- Slow or stopped breathing
- Inability to wake
- Extreme sleepiness
- Pinpoint pupils
- Cold or clammy skin
- Limp muscles
- Low blood pressure
- Unusual snoring or gurgling sounds
- Pale, gray, or blue lips and fingertips
Pinpoint pupils can occur during opioid overdose, though pupil size alone cannot confirm an overdose.
What to do during a suspected opioid overdose
- Call 911 immediately.
- Give naloxone if it is available.
- Follow the naloxone package instructions.
- Give another dose when directed if the person does not respond.
- Support breathing or begin CPR if you are trained.
- Place the person on their side once they are breathing independently.
- Stay with the person until emergency responders arrive.
Naloxone can restore breathing after an opioid overdose. Its effect may wear off before oxycodone leaves the body, so the person can stop breathing again.
Calling 911 remains necessary after naloxone has been given, even when the person wakes up.
Naloxone does not treat acetaminophen poisoning
Naloxone reverses opioid effects. It does not prevent liver damage caused by acetaminophen.
Someone who took too much T194 needs medical assessment for both ingredients. Hospital treatment for acetaminophen poisoning may include N-acetylcysteine, also called NAC. It works best when medical care begins early.
Do not wait for nausea, abdominal pain, or yellow skin to appear. Severe acetaminophen poisoning may cause few early symptoms.
Drug and alcohol interactions
Tell your prescriber and pharmacist about every prescription medicine, nonprescription product, vitamin, and supplement you use.
| Substance or medicine | Main concern |
|---|---|
| Alcohol | Severe sedation, breathing problems, overdose, and greater liver risk |
| Benzodiazepines | Profound sleepiness, coma, or fatal respiratory depression |
| Other opioids | Greater sedation and overdose risk |
| Sleeping medicines | Reduced awareness and impaired breathing |
| Gabapentin or pregabalin | Increased sedation and respiratory depression |
| Muscle relaxants | Greater sleepiness and breathing problems |
| Sedating antihistamines | Increased drowsiness and confusion |
| Other acetaminophen products | Accidental acetaminophen overdose |
| Some antidepressants | Serotonin syndrome or stronger side effects |
| Certain migraine medicines | Possible serotonin syndrome |
| Some antibiotics and antifungals | Increased oxycodone levels |
| Some seizure medicines | Reduced oxycodone levels or withdrawal |
Benzodiazepines include alprazolam, lorazepam, and diazepam. Combining one with an opioid can cause profound sedation, respiratory depression, coma, and death.
Some medicines can change how the liver processes oxycodone. Examples include clarithromycin, erythromycin, ketoconazole, itraconazole, ritonavir, carbamazepine, phenytoin, and rifampin.
Serotonergic medicines include some SSRIs, SNRIs, tricyclic antidepressants, triptans, trazodone, tramadol, cyclobenzaprine, and metaxalone.
The label does not recommend oxycodone and acetaminophen during MAOI treatment or within 14 days after stopping an MAOI. Urgent opioid use during this period requires clinician-directed test dosing and close monitoring.
Tell the prescriber if you use buprenorphine, butorphanol, nalbuphine, or pentazocine. These medicines can reduce oxycodone’s pain-relieving effect or cause withdrawal in someone who is physically dependent on opioids.
Do not stop a prescribed medicine or change its dose based on an interaction list. Ask the prescriber or pharmacist to review the combination.
Who should avoid T194?
The official label lists several contraindications. The medicine should not be used by someone with:
- Significant respiratory depression
- Acute or severe asthma without suitable medical monitoring
- Known or suspected bowel obstruction, including paralytic ileus
- A known allergy to oxycodone, acetaminophen, or another tablet ingredient
Several health conditions require extra caution and closer monitoring:
- COPD or another lung condition
- Sleep apnea
- A recent head injury
- Increased pressure inside the skull
- Seizure disorder
- Liver or kidney disease
- Thyroid problems
- Low blood pressure
- Difficulty urinating
- Pancreas or gallbladder disease
- Depression or another mental health condition
- A prior opioid overdose
- A personal or family history of substance use disorder
Adults aged 65 or older may be more sensitive to oxycodone. Reduced liver or kidney function can also cause the medicine to remain in the body longer.
Safety and effectiveness have not been established for pediatric patients. Accidental ingestion of even one dose can cause fatal respiratory depression in a child.
Counterfeit T194 pills and fentanyl
Counterfeit drug producers can copy the T194 imprint, white color, capsule shape, and plain reverse side. A tablet can closely match an online photograph and still contain fentanyl or another unexpected substance.
The safest source is a licensed pharmacy that dispenses the medicine in a labeled container. Tablets bought through social media, street sellers, friends, or unlicensed websites have an unknown identity and strength.
Do not depend on shade, texture, smell, taste, speckles, or tablet hardness. There is no dependable visual test for fentanyl.
If the tablet did not come from your pharmacy:
- Do not take it.
- Keep it away from children and pets.
- Ask a pharmacist to examine it.
- Contact Poison Control after a possible ingestion.
- Call 911 for overdose symptoms.
Ask a clinician or pharmacist about keeping naloxone available. This is especially relevant after a previous overdose, with an opioid use disorder, when other medicines can slow breathing, or when someone in the home is at risk of accidental ingestion. Family members should know where naloxone is stored and how to use it.
Tolerance, dependence, addiction, and withdrawal
These terms describe different experiences.
Tolerance
Tolerance means the same dose produces less effect after repeated use. Never respond by increasing the dose yourself.
Call the prescriber if the medicine stops controlling your pain or if your pain becomes worse.
Physical dependence
Physical dependence means the body has adapted to regular opioid exposure. A sudden dose reduction or discontinuation can cause withdrawal.
Dependence can happen during prescribed treatment. It does not automatically mean the person has an addiction.
Opioid use disorder
Opioid use disorder involves impaired control over opioid use or continued use despite harmful results. Signs can include strong cravings, taking more than prescribed, unsuccessful attempts to reduce use, and neglecting daily responsibilities.
Anyone concerned about their use should speak honestly with a healthcare professional. Treatment can include buprenorphine, methadone, or naltrexone. Counseling may also be part of care.
In the U.S., FindTreatment.gov and the SAMHSA National Helpline at 1-800-662-HELP (4357) can connect people with treatment services.
Withdrawal symptoms
Possible symptoms include:
- Restlessness
- Anxiety or irritability
- Sweating
- Runny nose
- Watery eyes
- Yawning
- Chills
- Muscle or joint pain
- Abdominal cramps
- Nausea or vomiting
- Diarrhea
- Trouble sleeping
- Faster heart rate or higher blood pressure
Do not stop regular opioid use suddenly. A prescriber can prepare a gradual, individual taper based on the dose, treatment length, health history, and response.
Pregnancy and breastfeeding
Tell your prescriber if you are pregnant, planning a pregnancy, or breastfeeding.
Using oxycodone for an extended period during pregnancy can cause neonatal opioid withdrawal syndrome. An affected newborn may develop irritability, shaking, abnormal sleep, a high-pitched cry, vomiting, diarrhea, feeding problems, or poor weight gain.
Use near labor can also affect a newborn’s breathing. A pregnant patient who has developed physical dependence should not stop suddenly without medical guidance.
Oxycodone passes into breast milk. The prescriber must consider the parent’s medical need, treatment dose, and the infant’s risk.
Seek immediate medical care if a breastfed infant develops unusual sleepiness, poor feeding, limpness, or breathing difficulty.
Safe storage and disposal
Store the tablets at 20°C to 25°C (68°F to 77°F). Protect them from moisture and keep them in the original pharmacy container.
Use a locked location that children, visitors, and other household members cannot access. Avoid leaving the bottle in a purse, bathroom, vehicle, or unlocked drawer.
Unused opioids should be removed from the home promptly. A pharmacy, police department, hospital, or DEA-authorized collection site may accept them.
A take-back program is the preferred disposal method. When one is unavailable, follow the medication label, current FDA disposal directions, or instructions from your pharmacist.
What should you do after finding a loose T194 pill?
Take these steps:
- Do not swallow the tablet.
- Keep it away from children and pets.
- Check both sides for the complete imprint.
- Record its color, shape, size, and score line.
- Look for the original labeled container.
- Ask a pharmacist to compare the tablet with official pill records and advise you on safe disposal.
- Contact Poison Control after a possible accidental ingestion.
- Call 911 for breathing problems, collapse, seizure, or inability to wake.
Do not place a loose opioid tablet into another prescription bottle. This can cause medication errors and may expose someone else to a fatal dose.

What kind of pill is T194?
T194 is a white to off-white, capsule-shaped tablet containing oxycodone hydrochloride 10 mg and acetaminophen 325 mg. It is a prescription Schedule II opioid medicine.
Is T194 a Percocet 10?
T194 has the same active ingredients and strength associated with Percocet 10/325. T194 is a generic product manufactured for Camber, and Percocet is a brand name.
Is T194 an immediate-release tablet?
Yes. It is an immediate-release oxycodone and acetaminophen tablet. Extended-release oxycodone products have different dosing instructions.
Is T194 a strong opioid?
Each tablet contains 10 mg of oxycodone. This dose can cause severe sedation and breathing problems, especially in someone without opioid tolerance. Take it only under the instructions of the prescriber who issued the prescription.
Can you take Tylenol with T194?
T194 already contains 325 mg of acetaminophen, the active ingredient in Tylenol. Taking another acetaminophen product can lead to an excessive total dose. Ask your pharmacist or prescriber before combining them.
Can you drink alcohol while taking it?
No. The Medication Guide warns patients to avoid alcohol. The combination can cause severe drowsiness, breathing problems, overdose, and greater liver damage.
How long do the effects last?
The label does not give one fixed duration of pain relief. Its Medication Guide describes taking the prescribed dose every 6 hours as needed. Response varies, so follow the pharmacy label and never repeat a dose early.
How long can oxycodone appear on a drug test?
The product label roughly estimates 1 to 2 days after a single oxycodone dose. Some urine tests may detect oxycodone for as long as 4 days. The window depends on the test, dose, repeated use, metabolism, and kidney or liver health. A laboratory or clinician should interpret the result.
Can a tablet with the correct imprint be counterfeit?
Yes. Counterfeit tablets can copy a legitimate imprint, color, and shape. A labeled prescription filled by a licensed pharmacy gives the most dependable confirmation of the source.
What if a child swallows one tablet?
If the child has trouble breathing, collapses, has a seizure, or cannot be awakened, call 911. Otherwise, call Poison Control at 1-800-222-1222 immediately. Accidental ingestion of one opioid dose can cause fatal respiratory depression in a child. Do not wait for symptoms.
