PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Assess frequency and nature of cough, lung sounds (See Appendix K), and amount and type of sputum produced. Document whether this drug is effective in reducing cough.
Assess dizziness that might affect gait, balance, and other functional activities (See Appendix C). Report balance problems and functional limitations to the physician, and caution the patient and family/caregivers to guard against falls and trauma.
Caution patient to avoid taking more than the recommended dose or taking alcohol or other CNS depressants concurrently with this medication; fatalities have occurred.
Instruct patient to cough effectively: sit upright and take several deep breaths before attempting to cough.
Advise patient to minimize cough by avoiding irritants, such as cigarette smoke, fumes, and dust. Humidification of environmental air, frequent sips of water, and sugarless hard candy may also decrease the frequency of dry, irritating cough.
Advise patient that any cough lasting more than 1 wk or accompanied by fever, chest pain, persistent headache, or skin rash warrants medical attention.
Instruct patient or family/caregivers to report other problematic side effects such as severe or prolonged nausea or sedation.
