Oxycodone

General Pain Management

Oxycodone is primarily used to treat pain that is severe enough to require an opioid analgesic. It is typically prescribed when alternative treatments, such as non-opioid pain relievers, do not provide enough relief or cannot be tolerated.

Types of Formulations

The medication is available in different forms depending on the nature of the pain and how long the relief needs to last:

• Immediate-release: These formulations are used for the short-term management of acute pain. They may be used on an as-needed basis as directed by a healthcare provider.
• Extended-release: These long-acting formulations are used for chronic pain that requires continuous, around-the-clock treatment. They are not intended for use on an as-needed basis or for pain that is expected to last only a short time.

Combination Products

Oxycodone is also frequently prescribed in combination with other non-opioid pain relievers, such as acetaminophen or ibuprofen, to treat moderate to severe acute pain. These combination products are intended to provide relief through multiple pathways.

How oxycodone works

Oxycodone belongs to a class of medications called opioid analgesics, also known as narcotics. It works by acting on the central nervous system to relieve pain.

The medication functions through the following processes:

• Interaction with receptors: Oxycodone binds to specific proteins called opioid receptors. These receptors are found in the brain, spinal cord, and other areas of the body.
• Pain signal interference: By attaching to these receptors, the drug helps block pain messages sent from the body to the brain.
• Changing pain perception: It does not eliminate the cause of the pain, but it changes how the brain and nervous system respond to it, making the person feel less pain.

Common Side Effects

Some side effects of oxycodone may go away as your body adjusts to the medication. Common side effects include:

• Nausea and vomiting
• Constipation
• Drowsiness or sleepiness
• Dizziness or lightheadedness
• Headache
• Dry mouth
• Sweating
• Itching
• Mood changes

Serious Side Effects

Contact your healthcare provider immediately or seek emergency medical care if you experience any of the following serious symptoms:

• Slowed, shallow, or stopped breathing
• Extreme sleepiness or inability to wake up
• Chest pain or a fast, pounding heartbeat
• Seizures
• Fainting or severe dizziness
• Signs of an allergic reaction, such as hives, rash, or swelling of the face, throat, tongue, or lips
• Confusion or hallucinations
• Severe muscle stiffness, twitching, or loss of coordination
• Fever, shivering, or sweating

Long-term use of opioids like oxycodone may also lead to adrenal insufficiency, which can cause symptoms like nausea, vomiting, loss of appetite, unusual tiredness, or dizziness. Additionally, taking this medication with certain other drugs can cause a serious condition called serotonin syndrome.

Addiction, Abuse, and Misuse

Oxycodone is an opioid medication that carries a high risk for addiction, abuse, and misuse. These behaviors can lead to overdose and death. It is important to store this medication securely to prevent others from taking it accidentally or intentionally.

Life-Threatening Breathing Problems

Serious or fatal breathing problems can occur while taking oxycodone, particularly when starting the medication or after a dose increase. The risk is higher for older adults or those with existing lung conditions like COPD or asthma.

Risks of Combining with Other Substances

Taking oxycodone with alcohol or other drugs that cause sleepiness (such as benzodiazepines, muscle relaxants, or sedatives) significantly increases the risk of severe drowsiness, breathing failure, coma, and death.

Accidental Ingestion

Even a single dose of oxycodone taken accidentally, especially by a child, can be fatal. This medication must be kept out of reach of children at all times.

Pregnancy and Newborn Risks

Prolonged use of oxycodone during pregnancy can cause the baby to experience life-threatening withdrawal symptoms after birth, a condition known as neonatal opioid withdrawal syndrome. This requires immediate medical attention for the newborn.

Other Precautions

• Adrenal Insufficiency: Long-term use may cause the adrenal glands to stop producing enough hormones.
• Low Blood Pressure: Oxycodone can cause a severe drop in blood pressure, leading to dizziness or fainting.
• Seizures: This medication may increase the risk of seizures in people with certain medical conditions.
• Gastrointestinal Issues: It should not be used by individuals with known or suspected bowel obstructions.

Pregnancy

Taking oxycodone during pregnancy may cause the baby to become physically dependent on the medication. This can lead to neonatal opioid withdrawal syndrome (NOWS) after birth, which can be life-threatening if not recognized and treated. Symptoms of withdrawal in a newborn may include:

• High-pitched crying and irritability
• Tremors or shaking
• Sleep problems
• Diarrhea or vomiting
• Failure to gain weight

If you are pregnant or planning to become pregnant, consult your healthcare provider to discuss the risks and determine the safest treatment plan for pain management.

Breastfeeding

Oxycodone passes into breast milk and can affect a nursing infant. Serious side effects in the baby can occur, such as:

• Extreme sleepiness or difficulty waking up
• Difficulty breastfeeding or poor feeding
• Limpness
• Breathing problems, which can be fatal

Healthcare providers typically advise monitoring the infant closely for these signs or considering alternative pain management options while breastfeeding. Always speak with a doctor before breastfeeding while taking oxycodone.

Available Dosage Forms

Oxycodone is primarily administered orally and comes in the following forms:

• Immediate-release tablets and capsules: These are used for pain that occurs suddenly or for short-term pain management.
• Oral solution: A liquid form of the medication, which may also be available as a concentrated solution for specific dosing needs.
• Extended-release tablets and capsules: These are designed to release the medication slowly over a longer period and are typically used for around-the-clock treatment of chronic pain.

Combination Products

Oxycodone is also frequently found in combination with other non-opioid pain relievers, such as:

• Acetaminophen (available in tablets and oral solutions)
• Ibuprofen (available in tablet form)
• Aspirin

Strengths

This medication is available in a wide range of strengths. Immediate-release versions often come in lower doses, while extended-release versions are available in higher strengths to provide consistent pain relief over 12 to 24 hours. The specific strength prescribed depends on the patient's medical history and the severity of the pain.

FDA Approval and Indications

Oxycodone is approved by the U.S. Food and Drug Administration (FDA) for the management of pain severe enough to require opioid treatment and for which alternative treatment options are inadequate or not tolerated. It is available in various formulations, including immediate-release and extended-release versions.

Boxed Warnings

The FDA requires a Boxed Warning for all oxycodone products due to several serious risks:

• Addiction, Abuse, and Misuse: Oxycodone exposes users to the risks of opioid addiction and abuse, 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: Accidental ingestion of even one dose, especially by children, can result in a fatal overdose.
• Neonatal Opioid Withdrawal Syndrome: Prolonged use of oxycodone during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated.

Safety Communications and REMS

The FDA has issued safety communications warning about the serious risks of combining opioid pain medicines with benzodiazepines or other central nervous system (CNS) depressants, including alcohol. This combination significantly increases the risk of profound sedation, respiratory depression, coma, and death.

To ensure the benefits of the drug outweigh the risks of addiction and overdose, the FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for opioid analgesics. This program requires that training be made available to healthcare providers and that patients are informed about the safe use and serious risks of these medications.

Risk of Addiction and Misuse

Oxycodone is an opioid pain medication with a high potential for addiction and substance use disorder. Addiction involves a strong, uncontrollable urge to use the drug despite the physical, social, or psychological harm it causes. Because of these risks, oxycodone is classified as a controlled substance.

Factors That Increase Risk

• Tampering: Crushing, chewing, snorting, or injecting the medication bypasses the delivery system, leading to a rapid release of the drug that significantly increases the risk of addiction and fatal overdose.
• History of Substance Abuse: Patients with a personal or family history of drug or alcohol abuse, or mental illness, may be at a higher risk for developing an addiction to oxycodone.
• Dosage and Duration: Taking higher doses or using the medication for an extended period can increase the likelihood of developing a substance use disorder.

Physical Dependence and Withdrawal

Long-term use of oxycodone can lead to physical dependence, which is different from addiction. Dependence means the body has adapted to the drug and will experience withdrawal symptoms if the medication is stopped suddenly. To avoid withdrawal, healthcare providers usually recommend tapering the dose gradually.

Safe Use and Storage

To minimize the risk of addiction and misuse, it is essential to follow these safety guidelines:

• Never share oxycodone with others, as it can be fatal to someone not prescribed the medication.
• Store the medicine in a secure, locked location away from children and others.
• Dispose of any unused medication immediately through a drug take-back program or by following specific FDA disposal instructions.
