Identifying the '176' Pill
The most common medication marked with the imprint '176' is a white, oval-shaped, biconvex tablet [1.2.6]. It has been identified as a combination of Acetaminophen (325 mg) and Hydrocodone Bitartrate (10 mg) [1.2.2, 1.2.3]. This medication is available by prescription only and is classified as a Schedule II controlled substance in the U.S., indicating a high potential for abuse and dependence [1.2.2]. It is commonly prescribed for conditions such as back pain, general pain, cough, and rheumatoid arthritis [1.2.3].
It is important to note that another pill also exists with the '176' imprint. This version is a peach, round pill identified as Venlafaxine Hydrochloride (37.5 mg), an antidepressant used to treat major depressive disorder and anxiety [1.2.4]. However, the white oval pill is the more frequent identification. Always confirm your medication with a pharmacist if you are uncertain.
Pharmacology: How Acetaminophen/Hydrocodone Works
This combination medication contains two active ingredients that work together to relieve pain.
- Acetaminophen: A non-opioid pain reliever and fever reducer. Its exact mechanism is not fully understood, but it is thought to work by inhibiting the production of prostaglandins in the brain, which are chemicals involved in pain and fever signaling.
- Hydrocodone: A semi-synthetic opioid analgesic [1.2.5]. It works by binding to mu-opioid receptors in the central nervous system (the brain and spinal cord). This action blocks pain signals from being sent to the brain, reducing the sensation of pain and producing a sense of euphoria, which contributes to its high potential for abuse [1.2.5].
Primary Uses and Dosage
The primary use for the pill '176' is the management of moderate to severe pain for which other treatments have proven ineffective [1.2.3, 1.2.5]. The typical dosage contains 325 mg of acetaminophen and 10 mg of hydrocodone bitartrate [1.2.5]. Taking this medication with food may help reduce the risk of nausea. It is critical to follow the prescribing doctor's instructions precisely and never take more than the recommended dose. Exceeding the daily limit of acetaminophen (4 grams) can lead to severe liver damage [1.2.5].
Risks, Side Effects, and Warnings
As a potent narcotic, this medication carries significant risks and potential side effects.
Common Side Effects:
- Drowsiness and Dizziness
- Nausea and vomiting
- Constipation
- Lightheadedness
Serious Risks:
- Addiction and Dependence: As a Schedule II opioid, hydrocodone has a high potential for abuse, which can lead to addiction [1.2.2, 1.2.5].
- Respiratory Depression: Opioids can slow breathing, which can be life-threatening, especially in cases of overdose or when mixed with other central nervous system depressants like alcohol or benzodiazepines [1.2.5].
- Liver Damage: Taking excessive amounts of acetaminophen can cause acute liver failure [1.2.5].
- Counterfeit Pills: There is a significant risk associated with pills obtained illicitly. The DEA reports that a high percentage of counterfeit pills seized on the street contain potentially lethal doses of fentanyl or methamphetamine [1.2.5].

Important Precautions
Before taking this medication, inform your doctor of your full medical history, especially any history of substance abuse, liver or kidney disease, or breathing problems. Do not drink alcohol while taking this medication, as it can dangerously increase the sedative effects. Due to the risk of drowsiness and impaired judgment, you should not drive or operate heavy machinery until you know how the medication affects you. If you need to stop taking the medication after long-term use, your doctor will likely recommend a gradual tapering of the dose to avoid withdrawal symptoms.
