The T257 white pill is a prescription hydrocodone/acetaminophen tablet containing 5 mg of hydrocodone bitartrate and 325 mg of acetaminophen. DailyMed describes the labeled tablet as off-white to white, capsule-shaped, debossed T 257 on one side, with a bisect line on the other. Hydrocodone makes it a Schedule II controlled substance.

T257 is especially easy to confuse with other hydrocodone/acetaminophen tablets because several products contain the same two active ingredients and the same 5 mg/325 mg strength. The imprint is therefore important. A legitimate T257 and an M365 tablet can contain the same labeled active ingredients and strength while coming from different product lines and carrying different markings.

An imprint can identify a legitimate pharmaceutical product, but it cannot prove that a loose tablet is authentic. Counterfeit tablets can imitate prescription markings. A pill obtained outside a licensed pharmacy should not be assumed to contain hydrocodone simply because it looks like T257.

What Is the T257 White Pill?

T257 is an immediate-release prescription pain medication that combines an opioid, hydrocodone, with the non-opioid pain reliever acetaminophen. The labeled indication is pain severe enough to require an opioid when other treatment options are inadequate.

The pill is not a separate drug called “T257.” T257 is the imprint used to identify this particular hydrocodone/acetaminophen product. The drug names and strengths matter more medically than the imprint itself, while the imprint helps distinguish one manufactured tablet from another.

T257 vs. M365: Are They the Same?

T257 and M365 can both identify tablets labeled as hydrocodone bitartrate 5 mg and acetaminophen 325 mg. That does not make the physical pills identical. They use different imprints and can be associated with different manufacturers or labelers.

T257 T 257 on one side; off-white/white capsule-shaped tablet; bisect line on the reverse
M365 M365 on one side; white capsule-shaped tablet; scored on the reverse
Active ingredients Both can contain hydrocodone 5 mg / acetaminophen 325 mg
Controlled status Both are Schedule II because they contain hydrocodone

For a reader trying to identify a tablet, the important point is that the same drug and strength can appear under different imprints. If a prescription bottle says one product but the tablets suddenly look different, a pharmacist can verify whether the pharmacy dispensed a different approved generic product.

What Do the T and 257 Mean?

The characters are an identification imprint. They are not instructions and they do not mean the tablet contains 257 mg of hydrocodone. DailyMed labeling for the T257 product identifies the strength as 5 mg hydrocodone bitartrate and 325 mg acetaminophen.

Nearby imprint numbers may represent different strengths within a manufacturer’s product line. That is another reason a person should not identify a pill from color alone. White or off-white hydrocodone products can look similar while containing different strengths.

What Is Hydrocodone?

Hydrocodone is an opioid analgesic. It acts on opioid receptors in the central nervous system to change the perception and response to pain. The same pharmacology can also produce sedation, impaired coordination, slowed breathing, tolerance, physical dependence, and opioid use disorder.

Hydrocodone combination products are federally controlled as Schedule II substances. Schedule II status reflects accepted medical use as well as a high potential for abuse and the possibility of severe physical or psychological dependence.

Why Does T257 Also Contain Acetaminophen?

Acetaminophen is a non-opioid pain reliever. Combining it with hydrocodone can provide pain relief through different mechanisms, but acetaminophen creates a second safety issue that is separate from opioid overdose.

Taking too much acetaminophen can cause serious liver injury. The FDA advises adults and children age 12 and older not to exceed 4,000 mg of acetaminophen in 24 hours from all medicines combined. Some people may be advised to use less based on their health and other risk factors.

Accidental duplication is possible because acetaminophen is used in many cold, flu, headache, and pain medicines. Someone taking a prescription combination product should check other medication labels and follow the prescriber’s instructions.

How Strong Is T257?

The labeled tablet strength is 5 mg of hydrocodone bitartrate and 325 mg of acetaminophen per tablet. The number printed on a pill-identification page should not be used as a personal dosing instruction.

Even a legitimately prescribed opioid can cause dangerous respiratory depression. Risk is influenced by opioid tolerance, other medications, alcohol or sedative use, respiratory disease, age, and other health factors. A strength that is appropriate for one patient may not be appropriate for another.

What Is T257 Prescribed For?

Hydrocodone/acetaminophen labeling describes the medication as an opioid analgesic used for pain severe enough to require an opioid when alternative treatments are inadequate. It should be used only by the person for whom it was prescribed.

Sharing prescription opioids is dangerous. A person who has little or no opioid tolerance can experience severe sedation or respiratory depression from a drug that another patient has previously taken without that reaction.

Common Side Effects

Hydrocodone/acetaminophen can affect alertness, balance, and the digestive system. Reported effects include:

  • Drowsiness
  • Dizziness or lightheadedness
  • Nausea
  • Vomiting
  • Constipation
  • Mental clouding
  • Reduced coordination or alertness

People should follow the medication label and prescriber’s directions about driving or operating machinery because opioid effects can impair reaction time and judgment.

T257 and Alcohol

Alcohol can intensify the central nervous system depressant effects of hydrocodone. Combining an opioid with alcohol can increase sedation and suppress breathing. Hydrocodone/acetaminophen labeling warns that combining opioids with alcohol or other central nervous system depressants can result in profound sedation, respiratory depression, coma, and death.

Alcohol use can also matter when acetaminophen is involved because liver health and drinking patterns can affect the clinician’s assessment of acetaminophen safety.

T257 and Benzodiazepines

Benzodiazepines such as alprazolam, clonazepam, lorazepam, and diazepam can also depress the central nervous system. Using a benzodiazepine with hydrocodone can substantially increase the risk of severe sedation and respiratory depression.

A prescriber should know about every sedating prescription, over-the-counter product, and substance a patient uses. A person should not add another sedative simply because it was prescribed to them at another time.

Can You Overdose on T257?

Yes. A T257 tablet contains an opioid and can contribute to an opioid overdose. Taking excessive amounts can also create acetaminophen toxicity.

Possible opioid overdose signs include:

  • Inability to wake the person
  • Very slow, shallow, irregular, or stopped breathing
  • Choking or gurgling sounds in an unresponsive person
  • Blue, gray, or markedly discolored lips or nails
  • Pinpoint pupils

If opioid overdose is suspected, call emergency services and give naloxone if it is available. Naloxone can temporarily reverse opioid effects. Emergency care is still necessary because the opioid may remain active after naloxone begins to wear off.

Can T257 Cause Addiction or Physical Dependence?

Yes. Hydrocodone can cause both physical dependence and opioid use disorder. These are related but not identical.

Physical dependence means the body has adapted to repeated opioid exposure and withdrawal can occur after abrupt discontinuation. Opioid use disorder involves a broader pattern that may include craving, impaired control, continued use despite harm, and compulsive use.

A patient can develop physical dependence while using medication as prescribed. That is why current opioid guidance warns against suddenly stopping opioids in a person who may be physically dependent. Any reduction should be individualized by the treating clinician rather than copied from a generic schedule online.

What Does Hydrocodone Withdrawal Feel Like?

Opioid withdrawal can include restlessness, watery eyes, runny nose, yawning, sweating, chills, muscle aches, enlarged pupils, anxiety, insomnia, abdominal cramps, nausea, vomiting, and diarrhea.

Withdrawal risk depends on how long the opioid has been used, the person’s total exposure, and individual factors. A person who is concerned about dependence should speak with the prescriber before changing the medication abruptly.

Can a Counterfeit Pill Have T257 on It?

Yes. Pharmaceutical imprints are useful for identifying known medications, but counterfeit manufacturers can copy markings. FDA warns that counterfeit medicines may contain the wrong ingredient, too much or too little active ingredient, no active ingredient, or other harmful ingredients.

The safest chain of custody is a medication dispensed by a licensed pharmacy in its labeled prescription container. A loose “T257” pill bought online, through social media, or from an unlicensed source should not be treated as authenticated hydrocodone.

What Should You Do if a T257 Pill Looks Different?

If a tablet from a legitimate prescription suddenly differs in color, shape, or imprint from what you normally receive, compare it with the prescription label and contact the dispensing pharmacy. Pharmacies can switch between approved generic products, but the pharmacist can confirm exactly what was dispensed.

If the pill did not come from your prescription or its source is unknown, do not rely on an image search alone to decide whether to take it.

When Is T257 a Medical Emergency?

Seek emergency medical help for severe sleepiness with inability to wake, slowed or stopped breathing, loss of consciousness, suspected opioid overdose, suspected counterfeit-pill exposure, or suspected dangerous acetaminophen ingestion.

If opioid overdose is possible, administer naloxone when available while emergency help is being obtained.

Treatment for Hydrocodone Misuse or Opioid Use Disorder

Treatment needs differ for someone who has used a prescription incorrectly once, someone who has developed physical dependence, and someone with opioid use disorder. An assessment can determine whether the person needs withdrawal management, medication for opioid use disorder, outpatient treatment, residential care, or another level of support.

FDA and SAMHSA recognize medications such as buprenorphine, methadone, and naltrexone as evidence-based options for opioid use disorder. Rehabs.Today can also be used to compare detox centers and residential treatment programs.
