Hydrocodone 2.5/500mg

Hydrocodone 2.5/500mg refers to a combination tablet containing 2.5mg of hydrocodone bitartrate and 500mg of acetaminophen. Hydrocodone is an opioid analgesic, while acetaminophen is a non-opioid pain reliever and fever reducer.

Historical U.S. labeling documented hydrocodone/acetaminophen tablets in the 2.5mg/500mg strength.

However, the regulatory status of this formulation is important. FDA requested that manufacturers limit prescription acetaminophen combination products to 325mg or less of acetaminophen per dosage unit because of the risk of severe liver injury. Current U.S. labeling for hydrocodone/acetaminophen products uses 325mg acetaminophen in the formulations listed by DailyMed.

Therefore, a product described as Hydrocodone 2.5/500mg should not automatically be assumed to be a currently FDA-approved U.S. formulation. The exact product, manufacturer, labeling, and regulatory status should be verified with a qualified pharmacist or healthcare professional.

What Is Hydrocodone 2.5/500mg?

Hydrocodone 2.5/500mg contains two active ingredients:

• Hydrocodone bitartrate 2.5mg – an opioid analgesic.

• Acetaminophen 500mg – a non-opioid analgesic and antipyretic.

Historical DailyMed labeling specifically identifies the 2.5mg/500mg combination as containing these quantities in each tablet.

Hydrocodone acts primarily through the central nervous system and opioid receptors to change the body's perception and response to pain. Acetaminophen provides additional analgesic activity through a different mechanism.

Because hydrocodone is an opioid, it carries important risks including sedation, respiratory depression, misuse, dependence, and overdose. The acetaminophen component also requires careful attention because excessive acetaminophen exposure can cause serious liver injury.

Important Information About the 500mg Acetaminophen Strength

The 500mg acetaminophen component is particularly important when discussing older hydrocodone combination formulations.

FDA asked manufacturers in 2011 to limit prescription combination products containing acetaminophen to no more than 325mg per dosage unit to reduce the risk of severe liver injury. FDA subsequently pursued withdrawal proceedings involving prescription acetaminophen combination products containing more than 325mg.

As a result, current U.S. hydrocodone/acetaminophen labeling generally reflects the lower acetaminophen amount.

Patients should not substitute an older 2.5mg/500mg formulation for a currently prescribed product without discussing it with a healthcare professional.

What Is Hydrocodone Used For?

Hydrocodone combination products have been used as prescription pain medicines for patients with pain that is considered appropriate for opioid treatment.

Depending on the specific product and clinical situation, hydrocodone/acetaminophen may be prescribed for:

• Acute injuries

• Postoperative pain

• Significant musculoskeletal pain

• Other painful conditions requiring opioid analgesia

The decision to use an opioid depends on the severity and cause of pain, other available treatments, previous opioid exposure, medical history, and individual risk factors.

How Does Hydrocodone 2.5/500mg Work?

Hydrocodone acts on opioid receptors in the central nervous system and changes how the brain and body perceive and respond to painful stimuli.

Acetaminophen contributes additional pain-relieving activity.

The combination therefore provides analgesic effects through different mechanisms. However, pain relief does not necessarily mean that the underlying cause of pain has been treated.

Hydrocodone 2.5/500mg Dosage Information

Dosage should always be individualized by a healthcare professional.

Historical labeling for hydrocodone 2.5mg/500mg described a usual adult dosage of one or two tablets every four to six hours as needed for pain, with a maximum of eight tablets per day for that particular historical formulation.

This historical information should not be interpreted as a current personalized dosing recommendation.

Patients should:

• Take hydrocodone exactly as prescribed.

• Never increase the dose without medical advice.

• Never take it more frequently than directed.

• Never share prescription opioid medication.

• Check other medicines for acetaminophen.

• Ask a pharmacist about unfamiliar strengths or formulations.

Acetaminophen Safety

Each historical 2.5mg/500mg tablet contains 500mg of acetaminophen. Taking multiple products containing acetaminophen can unintentionally increase total exposure.

Excessive acetaminophen can cause serious liver injury. This was a major reason FDA required prescription combination products to move toward no more than 325mg of acetaminophen per dosage unit.

Before taking another pain reliever, cold medicine, fever reducer, or other over-the-counter product, check its active ingredients for acetaminophen.

Patients with liver disease or a history of heavy alcohol use should discuss acetaminophen-containing medications with their healthcare professional.

Hydrocodone 2.5/500mg Side Effects

Hydrocodone can produce opioid-related side effects.

Possible effects include:

• Drowsiness

• Dizziness

• Nausea

• Vomiting

• Constipation

• Lightheadedness

• Sedation

• Sweating

These effects can interfere with alertness and coordination.

Patients should understand how the medicine affects them before driving or operating machinery.

Serious Side Effects

Hydrocodone can cause serious and potentially life-threatening respiratory depression.

Seek emergency medical assistance if someone taking hydrocodone develops:

• Very slow or shallow breathing

• Difficulty breathing

• Long pauses between breaths

• Extreme sleepiness

• Inability to wake up

• Loss of consciousness

• Severe allergic reaction

• Blue or gray lips or fingertips

Current hydrocodone/acetaminophen labeling contains warnings concerning opioid addiction, abuse, misuse, overdose, and life-threatening respiratory depression.

Hydrocodone and Alcohol

Alcohol can increase the sedative and respiratory-depressant effects of hydrocodone.

Combining an opioid with alcohol may increase the risk of:

• Excessive sedation

• Impaired coordination

• Breathing problems

• Loss of consciousness

• Overdose

Patients should avoid alcohol while taking hydrocodone unless their healthcare professional specifically advises otherwise.

Hydrocodone Drug Interactions

Hydrocodone may interact with medicines and substances that affect the central nervous system.

Examples include:

• Benzodiazepines

• Other opioids

• Alcohol

• Sleep medications

• Sedatives

• Certain antidepressants

• Other CNS depressants

Combining opioids with other CNS depressants can increase the risk of profound sedation and respiratory depression.

Always provide your healthcare professional with a complete list of prescription medications, over-the-counter products, vitamins, supplements, and other substances you use.

Dependence, Misuse, and Addiction

Hydrocodone is an opioid and carries risks of misuse, abuse, addiction, physical dependence, and withdrawal.

Taking more than prescribed, taking it more frequently than directed, or using it for reasons other than prescribed treatment can increase these risks.

Physical dependence can occur with regular opioid exposure. Patients who have been taking hydrocodone regularly should speak with their healthcare professional before stopping treatment.

Hydrocodone Withdrawal

Stopping regular opioid treatment suddenly may cause withdrawal symptoms.

Possible symptoms include:

• Restlessness

• Anxiety

• Sweating

• Chills

• Muscle aches

• Runny nose

• Yawning

• Abdominal cramps

• Nausea

• Vomiting

• Diarrhea

• Difficulty sleeping

A healthcare professional can determine whether the medication should be reduced gradually and how discontinuation should be managed safely.

Who Should Discuss Hydrocodone With a Doctor?

Before using hydrocodone/acetaminophen, tell your healthcare professional if you have:

• Breathing problems

• Asthma or COPD

• Liver disease

• Kidney problems

• A history of seizures

• A history of substance misuse

• Previous opioid-related problems

• Gastrointestinal conditions

• Pregnancy or plans to become pregnant

• Breastfeeding

Patients taking other sedating medicines may require additional monitoring because of the risk of excessive sedation and respiratory depression.

Hydrocodone and Driving

Hydrocodone can cause drowsiness, dizziness, lightheadedness, and impaired coordination.

Do not drive, operate heavy machinery, or perform hazardous activities until you know how the medication affects you.

Extra caution is appropriate when treatment is first started or when other medications are added.

Hydrocodone and Naloxone

Patients receiving opioid therapy can discuss naloxone with their healthcare professional.

Naloxone is an opioid overdose reversal medication that can temporarily reverse opioid effects and help restore breathing during an overdose.

Family members and caregivers may also benefit from knowing the signs of opioid overdose and how naloxone is used when appropriate.

Safe Storage and Disposal

Hydrocodone should be stored securely and kept out of the reach of children and other people who could accidentally or intentionally take it.

Keep the medication in its original container whenever possible and follow the product-specific storage instructions.

Unused opioid medication should be disposed of through an appropriate medication take-back program when available. A pharmacist can provide guidance about safe disposal options.
