Concomitant use of Pseudoephedrine, guaiphenasine & triprolidine with sympathomimetic agents such as decongestants, tricyclic antidepressants, appetite suppressants and amphetamine-like psychostimulants or with monoamine oxidase inhibitors which interfere with the catabolism of sympathomimetic amines may occasionally cause a rise in blood pressure. Because of its pseudoephedrine content, Pseudoephedrine, guaiphenasine & triprolidine partially reverse the hypotensive action of drugs which interfere with sympathetic activity including guanethidine, methyldopa, alpha-adrenergic blocking agents.
CNS depression or excitation, drowsiness (reported most frequently), sleep disturbances, hallucinations (rarely reported), skin rashes with or without irritation, tachycardia, dryness of mouth, nose and throat have occasionally been reported.
Although pseudoephedrine, triprolidine and guaiphenesin have been in widespread use of many years without apparent ill consequence, there are no specific data on their use during pregnancy. Caution should therefore be exercised by balancing the potential benefits of treatment of the mother against any possible hazards to the developing fetus.
As with any other antihistamine therapy, Pseudoephedrine, guaiphenasine & triprolidine may cause drowsiness. If affected, patients should be advised not to drive or operate machinery. Concomitant administration of alcohol or other centrally acting sedatives should be avoided. Although Pseudoephedrine has no pressor effects in normotensive patients but Pseudoephedrine, guaiphenasine & triprolidine should be used with caution to patients suffering from mild to moderate hypertension. Moreover, caution should also be exercised in the following disease conditions - hypertension and heart disease, diabetes, hyperthyroidism, elevated intra-ocular pressure, prostatic enlargement, severe renal and hepatic impairment. This preparation should not be used for persistent or chronic cough, which occurs with smoking, asthma or emphysema or where excessive secretions accompany cough, unless directed by a physician.
The effects of acute toxicity from Pseudoephedrine, guaiphenasine & triprolidine may include drowsiness, irritability, restlessness, lethargy, dizziness, gastrointestinal discomfort, respiratory depression, convulsion, tremor, tachycardia and hypertension. Incase of overdose, necessary measures should be taken to maintain and support respiration and control convulsion. Gastric lavage may be undertaken if indicated. Catheterization of bladder may be necessary.
