PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Monitor signs of allergic reactions and anaphylaxis, including pulmonary symptoms (tightness in the throat and chest, wheezing, cough, dyspnea) or skin reactions (rash, pruritus, urticaria). Notify physician or nursing staff immediately if these reactions occur.
Be alert for signs of systemic infections, especially respiratory infections (fever, chills, cough, mucus production, shortness of breath, wheezing, chest discomfort, fatigue) and GI infections (nausea, vomiting, diarrhea, abdominal pain). Notify physician immediately of these signs.
Monitor signs of hematologic reactions such as leukopenia (fever, sore throat, signs of infection), thrombocytopenia (bruising, nose bleeds, and bleeding gums), or unusual weakness and fatigue that might be due to anemia. Report any suspicious signs of blood disorders.
Monitor any changes in GI symptoms (decreased abdominal pain, decreased diarrhea, improved appetite) to help document whether drug therapy is successful in managing Crohn's disease.
Assess any joint pain to rule out musculoskeletal pathology; that is, try to determine if pain is drug induced rather than caused by anatomic or biomechanical problems.
Monitor signs of lupus-like syndrome, including increased blood pressure (BP), fever, joint pain, skin rashes, and redness/irritation of the eye (uveitis). Notify physician promptly if these signs appear.
Advise patient to avoid alcohol and foods that may cause an increase in GI irritation.
Instruct patient and family/caregivers to report other troublesome side effects such as severe or prolonged skin reactions (rash, dermatitis).
Absorption: 80% absorbed following SC administration.
