What are the possible side effects of Norco?

Norco (hydrocodone and acetaminophen), a prescription drug used to treat moderate to moderately severe pain, can cause a number of side effects. The most common include:
  • nausea
  • drowsiness
  • lightheadedness
  • headache
  • constipation
Other less common side effects from Norco include:
  • anxiety, fear, depression, unusual thinking or moods
  • weakness
  • mental fogginess
  • trouble urinating
  • dry throat
  • itching or rash
If any of these symptoms are severe or persist, tell your doctor. Also, call your doctor immediately if you experience any of these rarer but more serious symptoms:
  • slow and shallow breathing
  • extreme drowsiness, dizziness or confusion
  • fainting
  • slower or faster heartbeat than normal
  • seizures
  • low blood pressure
Norco may cause physical dependence. Do not stop taking the drug, or any other opioid, without talking to your doctor first. Suddenly stopping Norco may cause withdrawal symptoms.

There is a risk of abuse or addiction with this medication. The chance is increased if you are, or have ever been, addicted to or abused other medicines, street drugs or alcohol, or if you have a history of mental health problems.
