General
The more commonly expected adverse effects include nausea, vomiting, and dizziness.[Ref]
Nervous system
Codeine
Frequency not reported: CNS depression, lightheadedness, dizziness, sedation, headache, convulsions, weakness
Pseudoephedrine:
Frequency not reported: Restlessness, dizziness, weakness, headache, drowsiness, tremor[Ref]
Cardiovascular
Codeine
Frequency not reported: Tachycardia, bradycardia, palpitation, faintness, syncope, orthostatic hypotension, circulatory depression

Frequency not reported: Tachycardia, palpitations, cardiac arrhythmias, hypertension, impaired circulation to the extremities, coronary artery spasm, chest pain[Ref]
Hypotension is rare and has been reported most frequently with high doses of codeine.
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.[Ref]
Gastrointestinal
Codeine
Frequency not reported: Nausea, vomiting, constipation, biliary tract spasm, increased colonic motility, toxic dilation
Guaifenesin:
Frequency not reported: Abdominal pain (upper), diarrhea, nausea, vomiting
Pseudoephedrine:
Frequency not reported: Nausea, vomiting, dry mouth, ischemic colitis[Ref]
Patients with chronic ulcerative colitis may experience increased colonic motility, while patients with acute ulcerative colitis have experienced toxic dilation with codeine use.[Ref]

Respiratory
Codeine:
Frequency not reported: Respiratory depression
Respiratory depression has been associated with antitussive use of codeine in young children. Respiratory depression and death have occurred in children who received codeine in the postoperative period following tonsillectomy and/or adenoidectomy. Further investigation has shown these patients to be ultra-rapid metabolizers of codeine. Children with obstructive sleep apnea who are treated with codeine appear to be particularly sensitive to the respiratory depressant effects of codeine.
