Nasatapp Special Precautions

Phenylpropanolamine HCl: Sympathomimetic agents should be used with caution in patients which may be particularly susceptible to their effects, particularly those with hyperthyroidism. Great care is also needed in patients with cardiovascular disease eg, ischemic heart disease, arrhythmia or tachycardia, occlusive vascular disorders eg, arteriosclerosis, hypertension or aneurysms. Anginal pain may be precipitated in patients with angina pectoris.
Excessive administration of sympathomimetic agents to the nasal mucosa may produce rebound congestion and rhinorrhea. Care is also required when sympathomimetic agents are given to patients with diabetes mellitus or closed-angle glaucoma.
Brompheniramine Maleate: Antihistamine should not be given to premature infants or neonates. This group of patients has an increased susceptibility to antimuscarinic effects. Elderly patients are also more susceptible to many adverse effects of antihistamines including antimuscarinic effects, sedation and hypotension.
Because of their antimuscarinic properties, antihistamines should be used with care in conditions eg, closed-angle glaucoma, urinary retention, prostatic hypertrophy, or pyloroduodenal obstruction.
Effects on the Ability to Drive or Operate Machinery: Brompheniramine Maleate: Many antihistamines may cause drowsiness, so patients affected should not drive or operate machinery. Patients should avoid alcoholic drink.
