Norco

Pain Relief

Norco is primarily used for the management of pain that is severe enough to require an opioid analgesic and for which alternative treatments, such as non-opioid medications, are inadequate or cannot be tolerated. It is a combination of two different types of pain-relieving ingredients:

• Hydrocodone: An opioid pain reliever that acts on the central nervous system to change how the body perceives and responds to pain.
• Acetaminophen: A non-opioid pain reliever and fever reducer that increases the effectiveness of the hydrocodone.

This medication is often prescribed for acute pain, such as pain following a surgical procedure or a significant injury. Because it contains an opioid, it is generally intended for short-term use under close medical supervision.

How Norco Works

Norco is a combination of two pain-relieving medicines: hydrocodone and acetaminophen. These ingredients work together through different mechanisms in the central nervous system to reduce the sensation of pain.

• Hydrocodone is an opioid analgesic. It works by attaching to specific proteins called opioid receptors in the brain and spinal cord. This action interferes with the transmission of pain signals to the brain and changes how the body perceives and responds to pain.
• Acetaminophen is a non-opioid pain reliever and fever reducer. While its exact mechanism is not fully understood, it is believed to work by increasing the body's overall pain threshold.

By using two different pathways to address pain, the combination of these ingredients provides more relief than either medication would provide on its own.

Common Side Effects

The most frequent side effects associated with this medication include:

• Drowsiness or sleepiness
• Dizziness or lightheadedness
• Nausea and vomiting
• Constipation
• Stomach pain
• Blurred vision
• Dry mouth

Serious Side Effects

Seek medical attention immediately if you experience any of the following:

• Slow, shallow, or difficult breathing
• Confusion, hallucinations, or extreme mood changes
• Severe skin reactions, such as a rash that spreads and causes blistering or peeling
• Difficulty urinating
• Signs of liver damage, including yellowing of the skin or eyes, dark urine, or pain in the upper right stomach
• Chest pain or a fast, irregular heartbeat
• Extreme weakness or loss of appetite

Get emergency help if you have signs of an allergic reaction, such as hives, swelling of the face or throat, or difficulty swallowing.

Boxed Warnings

Norco is associated with several serious risks that are highlighted in boxed warnings:

• Addiction, Abuse, and Misuse: Use of this medication increases the risk of opioid addiction and misuse, which can lead to overdose and death.
• Life-Threatening Respiratory Depression: Fatal breathing problems may occur, particularly when starting the medication or increasing the dose.
• Accidental Ingestion: Ingesting even a single dose by accident, especially by a child, can be fatal.
• Neonatal Opioid Withdrawal Syndrome: Use during pregnancy for an extended period can cause life-threatening withdrawal symptoms in the newborn.
• Risks from Concomitant Use with Benzodiazepines: Combining opioids with benzodiazepines, other central nervous system depressants, or alcohol may result in profound sedation, respiratory depression, coma, and death.

Liver Toxicity

The acetaminophen component of Norco is linked to cases of acute liver failure. This risk is highest when the total daily dose of acetaminophen exceeds 4,000 milligrams or when multiple products containing acetaminophen are used simultaneously.

Serious Skin Reactions

Acetaminophen may cause rare but serious skin conditions, such as Stevens-Johnson Syndrome and toxic epidermal necrolysis. These reactions are medical emergencies and can be fatal.

Contraindications

The use of Norco is contraindicated in individuals with:

• Significant respiratory depression.
• Acute or severe bronchial asthma.
• Known or suspected gastrointestinal obstruction, including paralytic ileus.
• Hypersensitivity to hydrocodone or acetaminophen.

Other Precautions

Opioid use may lead to adrenal insufficiency, a condition where the body does not produce enough of certain hormones. Symptoms can include nausea, fatigue, and dizziness. Additionally, Norco may cause severe low blood pressure or increased pressure inside the skull, which can be dangerous for individuals with head injuries.

Pregnancy

Prolonged use of opioid medications like Norco during pregnancy can lead to neonatal opioid withdrawal syndrome. This condition occurs because the baby becomes dependent on the medication while in the womb and may experience life-threatening withdrawal symptoms after birth. Symptoms in the newborn may include irritability, hyperactivity, abnormal sleep patterns, high-pitched crying, tremor, vomiting, diarrhea, and failure to gain weight.

If you are pregnant or planning to become pregnant, discuss the risks and benefits of this medication with your healthcare provider. It should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

Breastfeeding

The active ingredients in Norco, hydrocodone and acetaminophen, pass into breast milk. This can cause side effects in a nursing infant, such as:

• Increased sleepiness or difficulty waking up
• Difficulty breastfeeding
• Breathing problems
• Limpness

If you are breastfeeding, consult your doctor before using this medication. If you use Norco while breastfeeding, monitor your baby closely for signs of excessive sedation or respiratory distress and seek immediate medical attention if these occur.

Available Forms

Norco is supplied as a tablet for oral administration. It is a combination product that contains both hydrocodone bitartrate and acetaminophen.

• Oral Tablet: This medication is manufactured as a solid tablet intended to be swallowed.

The tablets are typically debossed with specific codes and may be scored on one side to assist with identification. While the ratio of the active ingredients may vary across different versions of the medication, the dosage form remains a tablet.

FDA Approval and Indications

Norco, a combination of hydrocodone bitartrate and acetaminophen, is FDA-approved for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Because of the risks of addiction, abuse, and misuse, it is reserved for cases where other pain management options, such as non-opioid medicines, have not been tolerated or do not provide enough relief.

Boxed Warnings

The FDA requires a Boxed Warning for Norco due to several serious safety risks:

• Addiction, Abuse, and Misuse: Use of Norco exposes patients to the risks of opioid addiction, which can lead to overdose and death.
• Life-Threatening Respiratory Depression: Serious or fatal breathing problems may occur, particularly when starting the medication or after a dose increase.
• Accidental Ingestion: Even a single accidental dose, especially by a child, can be fatal.
• Neonatal Opioid Withdrawal Syndrome: Prolonged use during pregnancy can result in life-threatening withdrawal symptoms in the newborn.
• Hepatotoxicity: The acetaminophen component is associated with cases of acute liver failure, sometimes resulting in liver transplant or death.

Regulatory Classification

Norco is classified by the Drug Enforcement Administration (DEA) as a Schedule II controlled substance. This classification reflects its high potential for abuse and the risk that use may lead to severe psychological or physical dependence.

Safety Communications and REMS

The FDA has issued safety communications warning against the combined use of opioids like Norco with benzodiazepines or other central nervous system (CNS) depressants, as this can result in profound sedation, respiratory depression, coma, and death. Additionally, Norco is part of the Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS), a program designed to ensure that the benefits of the drug outweigh its risks through provider education and patient counseling.

Withdrawal Symptoms

If Norco is discontinued abruptly after long-term use, you may experience various withdrawal symptoms. These can include:

• Restlessness, irritability, or anxiety
• Muscle, joint, or back pain
• Stomach cramps, nausea, vomiting, or diarrhea
• Sweating, chills, or shivering
• Runny nose, watery eyes, or yawning
• Dilated pupils
• Difficulty sleeping
• Increased heart rate, blood pressure, or breathing rate

Managing Discontinuation

To avoid withdrawal, do not stop taking this medication suddenly. Your doctor should help you gradually decrease the dose over time. If you experience any of these symptoms while tapering, contact your healthcare provider immediately.
