Hydrocodone is an opioid pain reliever prescribed for moderate to severe pain management. It works by altering the way the brain and nervous system respond to pain. Often combined with acetaminophen, it is available in tablet or liquid form. Due to its addictive nature, it should only be used as prescribed and for short periods. Misuse or prolonged use can lead to serious side effects, including dependency, respiratory depression, and overdose. Always follow medical guidance when using Hydrocodone.
