Side Effects by Body System

Nervous system

Opiates may result in psychotic symptoms in some patients.

Nervous system side effects of hydrocodone have included mental and respiratory depression, stupor, delirium, somnolence, and dysphoria. Nervous system side effects of pseudoephedrine have included insomnia in up to 30% of patients. Tremor, anxiety, nervousness, and headache have also been reported.

Other side effects of hydrocodone have included withdrawal symptoms, such as agitation, restlessness, anxiety, insomnia, tremor, abdominal cramps, blurred vision, vomiting and sweating, after either abrupt cessation or fast tapering of narcotic analgesics.

Gastrointestinal

Gastrointestinal side effects of hydrocodone have included nausea, vomiting, constipation, and dry mouth. Gastrointestinal side effects of pseudoephedrine have included anorexia and gastric irritation in approximately 5% of patients. Dry mouth, nose, or throat have occurred in up to 15% of patients.

Cardiovascular

Cardiovascular side effects of pseudoephedrine have included tachycardia. Some patients have developed hypertension and/or arrhythmias.

Pseudoephedrine causes vasoconstriction which generally does not produce hypertension, but may be problematic for patients with preexisting hypertension. Arrhythmias may be produced in predisposed patients. Rarely, pseudoephedrine has been reported to cause coronary artery spasm and chest pain.

One report evaluated the effect with 60 mg of pseudoephedrine on individuals in a hyperbaric chamber at 1 atmosphere (simulated scuba dive to 66 feet of sea water). Pseudoephedrine and depth (simulated) were found to have significant but opposite effects on heart rate, although these effects were unlikely to be clinically significant during diving.

Genitourinary

Genitourinary side effects of hydrocodone have included ureteral spasm, spasm of vesicle sphincters, and urinary retention.

Dermatologic

Dermatologic side effects of hydrocodone have included rash.
