PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Assess dizziness and drowsiness 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.
Assess any muscle pain to rule out musculoskeletal pathology; that is, try to determine if pain is drug induced rather than caused by anatomic or biomechanical problems.
Periodically assess body weight and other anthropometric measures (body mass index, body composition). Report a rapid or unexplained weight gain or increased body fat.
Guard against falls and trauma (hip fractures, head injury, and so forth). Implement fall prevention strategies, especially in older adults or if balance is impaired (See Appendix E).
Advise patient about the risk of daytime drowsiness and decreased attention and mental focus. These problems can be severe in certain people. Use care if driving or in other activities that require quick reactions and strong concentration.
Advise patient to avoid alcohol and other CNS depressants because of the increased risk of sedation and adverse effects.
Instruct patient to report prolonged or severe nasal irritation, including excessive sneezing, nosebleeds, burning sensations, or other troublesome nasopharyngeal symptoms.
Instruct patient and family/caregivers to report severe or prolonged headache, fatigue, or GI problems (nausea, dry mouth, bitter taste).
