WARNINGS Sympathomimetic amines should be used judiciously and sparingly in patients with hypertension, diabetes mellitus, ischemic heart disease, increased intraocular pressure, hyperthyroidism, or prostatic hypertrophy. Sympathomimetics may produce CNS stimulation and convulsions or cardiovascular collapse with accompanying hypotension. Do not exceed recommended dosage. Hypertensive crises can occur with concurrent use of Pseudoephedrine and an MAO inhibitor, and for 14 days after stopping the MAO inhibitor therapy, indomethacin, or with beta blockers and methyldopa. If a hypertensive crisis occurs, these drugs should be discontinued immediately and therapy in lower blood pressure should be instituted. Fever should be managed by means of external cooling.
ADVERSE REACTIONS Pseudoephedrine Pseudoephedrine may cause mild central nervous system stimulation, especially in those patients who are hypersensitive to sympathomimetic drugs. Nervousness, excitability, restlessness, dizziness, weakness and insomnia may also occur. Headache and drowsiness have also been reported. Large doses may cause lightheadedness, nausea and/or vomiting. Sympathomimetic drugs have also been associated with certain untoward reactions including fear, anxiety, tenseness, restlessness, tremor, weakness, pallor, respiratory difficulty, dysuria, insomnia, hallucinations, convulsions, CNS depression, arrhythmias, and cardiovascular collapse with hypotension. Guaifenesin No serious side effects have been reported with Guaifenesin.
