What is Hydrocodone?
​

​1. Introduction


Definition: Hydrocodone is an opioid analgesic, meaning it's a pain-relieving medication that works by changing the way the brain and nervous system respond to pain
Classification: Opioid, Narcotic Analgesic.
Common Uses:
Pain relief (moderate to severe pain)
Cough suppression (in combination with other medications)

2. Mechanism of Action

How it works: Hydrocodone binds to opioid receptors in the brain and spinal cord, blocking pain signals and altering the perception of pain.
Pain Relief: Increases the effects of natural pain-relieving chemicals in the body (endorphins) and inhibits the transmission of pain signals.
3. Dosage and Administration
​
​​
  • Forms: Oral tablets, oral syrup, or combination products (e.g., hydrocodone/acetaminophen or hydrocodone/ibuprofen).
  • Common Dosage:
    • For pain: Typically 5 to 10 mg every 4 to 6 hours as needed.
    • For cough: 5 to 10 mg every 4 to 6 hours (depending on product formulation).
  • Maximum Dosage: Depends on the formulation and patient condition, but generally no more than 60 mg per day.
  • Route of Administration: Oral.

5. Risks and Warnings
​
  • Common Side Effects:
    • Drowsiness or sedation
    • Dizziness or lightheadedness
    • Nausea or vomiting
    • Constipation
  • Serious Side Effects:
    • Respiratory depression (slow or shallow breathing)
    • Dependence or addiction (risk increases with long-term use)
    • Liver damage (if combined with acetaminophen in high doses)
  • Allergic Reactions: Rash, itching, or swelling (especially of the face/tongue/throat).
 
  • Addiction, Abuse, and Misuse: Hydrocodone is classified as a Schedule II controlled substance in the U.S. due to its potential for abuse and addiction.
  • Respiratory Depression: Particularly in the elderly or those with lung conditions.
  • Withdrawal Symptoms: If discontinued suddenly after long-term use, withdrawal symptoms may occur, including anxiety, sweating, muscle pain, and irritability.
Overdose Risk: Symptoms of overdose include slow or difficult breathing, confusion, or loss of consciousness. Overdose requires immediate medical attention.

​6. Contraindications

​
  • Do not use if:
    • You are allergic to hydrocodone or other opioids.
    • You have severe asthma, breathing problems, or bowel obstruction (paralytic ileus).
    • You are using certain medications like MAO inhibitors.
  • Pregnancy: Hydrocodone should be used only if the potential benefits outweigh the risks to the fetus. It may cause withdrawal symptoms in a newborn if taken late in pregnancy.
  

Conclusion
Hydrocodone can be effective for managing pain but must be used carefully to avoid risks like addiction, overdose, and serious side effects. Always follow your healthcare provider's instructions and avoid misuse.​
