https://bigpharmausa.com/pain-relief/hydrocodone/ Hydrocodone is a prescription drug used for the treatment of severe pain. It is categorized as a narcotic analgesic, which works by modifying the perception of pain in the brain and nervous system. Extended-release versions are specifically formulated for adults who need ongoing, long-term pain management. This medication is available in both extended-release tablet and capsule forms, typically taken up to twice a day, depending on the prescribed formulation. It is crucial not to chew, break, crush, dissolve, or otherwise modify the extended-release tablets and capsules; they must be swallowed whole. Additionally, hydrocodone is available in various combination products, but this discussion focuses exclusively on the single-entity formulation. Common side effects of hydrocodone include nausea, vomiting, constipation, dizziness, anxiety, mood changes, rashes, and itching. Moreover, hydrocodone may cause drowsiness and lightheadedness; therefore, individuals should avoid driving or operating heavy machinery until they fully understand how the medication affects them.
