As a narcotic, hydrocodone relieves pain by binding to opioid receptors in the brain and spinal cord. It can be taken with or without food as one prefer.
As always there are side effects, these include dizziness, light-headedness, nausea, drowsiness, constipation, vomiting, and euphoria. Some less known common side effects are an allergic reaction, blood disorders, changes in mood, mental fogginess, anxiety, lethargy, experience difficulty urinating, spasm of the ureter, irregular or depressed respiration, and rash.
If with alcohol, it can increase drowsiness. It may interact with monoamine oxidase inhibitors, as well as other drugs that cause drowsiness. It is in FDA pregnancy category B: its effect on an embryo or fetus is not clearly known and pregnant women should seek medical advice before taking it.
Always be safe than sorry so precaution is always prudent. Hydrocodone is habit-forming, and can lead to physical and psychological addiction, but the potential for addiction varies from individual to individual depending on unique biological differences.
Hydrocodone is typically found in combination with other drugs such as paracetamol aspirin, ibuprofen, and homatropine methylbromide.
