Hydrocodone has a chemical structure that is related to that of codeine and morphine. Hydrocodone combination products are formulated in tablets, capsules, and syrups.

Most often these drugs are abused by oral rather than intravenous administration.

Hydrocodone, like most other opioids, induces euphoria, sedation and alters the perception of painful stimuli.

Hydrocodone can cause drowsiness, dizziness, nausea, constipation, urinary retention and in higher amounts, depressed respiration. Long term use can lead to dependence and addiction. Withdrawal symptoms include restlessness, muscle and bone pain, insomnia, diarrhea, and vomiting.

Morphine, heroin, oxycodone, codeine, propoxyphene, fentanyl, and hydromorphone.

Like other opioids, hydrocodone overdose is associated with cold and clammy skin, severely constricted pupils, and slow breathing that can lead to a loss of consciousness and death. Large doses of hydrocodone in combination with acetaminophen may cause severe liver damage.
