Acetaminophen-codeine #3 provides relief from fever and mild to moderate pain when taken as directed, according to WebMD. It may also be prescribed to suppress coughing. In addition to these beneficial effects, the drug can cause nausea, vomiting and constipation. Drowsiness, dizziness and lightheadedness are additional side effects.
Serious side effects associated with acetaminophen-codeine #3 include difficulty urinating, mental or mood changes, and severe stomach or abdominal pain, notes WebMD. Fainting and seizures occur rarely and require immediate medical attention.
Certain patients should avoid taking acetaminophen-codeine #3, including individuals who have taken an MAO inhibitor within the last 14 days and those who have recently used alcohol, sedatives or other narcotic drugs, states Drugs.com. Additionally, caution should be used by those who have a history of drug or alcohol abuse, liver disease, bowel obstruction, kidney disease or breathing disorders.
Acetaminophen-codeine #3 can be habit forming or cause tolerance, especially if used for an extended period of time, states WebMD. This is true even when a person takes the medication as prescribed. Stopping acetaminophen-codeine #3 suddenly can lead to severe withdrawal symptoms, especially for patients who have been taking the drug for an extended period. The dose should be tapered slowly.
