WARNINGS Sympathomimetic amines should be used judiciously and sparingly in patients with hypertension, diabetes, ischemic heart disease, hyperthyroidism, increased intraocular pressure, or prostatic hypertrophy. (See CONTRAINDICATIONS ). Sympathomimetic amines may produce CNS stimulation with convulsions or cardiovascular collapse with accompanying hypotension. The elderly (60 years and older) are more likely to exhibit adverse reactions. A persistent cough may be a sign of a serious condition. If cough persists for more than one week or tends to recur, or is accompanied by fever, rash, or persistent headache, patient re-evaluation should be considered.
