SIDE-EFFECTS AND SPECIAL PRECAUTIONS: Pseudoephedrine may cause giddiness, headache, nausea, vomiting, sweating, thirst, tachycardia, pre-cordial pain, palpitation, difficulty with micturition, muscular weakness and tremors, anxiety, restlessness and insomnia. Hypertension and ventricular arrhythmias may occur. Pseudoephedrine HCl should be given with caution to patients with organic heart disease, cardiac decompensation or angina of effort. In patients with prostatic enlargement, it may cause difficulty with micturition. Other side-effects of pseudoephedrine include agitation, loss of appetite, reflex bradycardia cardiac arrest, contusion dizziness dyspnoea, fainting, fear, blushing, disturbance of glucose metabolism, irritability, dry mouth, psychotic states, vasoconstriction which may result in hypertension, cerebral haemorrhage and pulmonary oedema, and weakness. Fixed drug eruption due to pseudoephedrine HCl, taking the form of erythematous nummular patches has been reported.
ACUTUSSIVE EXPECT ADULT should be used with caution in patients with aneurisms, cardiac arrhythmias (e.g. tachycardia), diabetes mellitus and occlusive vascular disorders (arteriosclerosis). It should be used carefully in elderly and debilitated patients. Tolerance may develop when given to asthmatics for their asthmatic effects.
The most common side-effects of triprolidine HCl are sedation varying from slight drowsiness to deep sleep, and including inability to concentrate, lassitude, dizziness, hypotension, muscular weakness and incoordination. Other side-effects include gastro-intestinal disturbances such as nausea, vomiting, diarrhoea or constipation and epigastric pain. Headache, tinnitus, elation or depression, irritability, nightmares, anorexia, difficulty with micturition, dryness of the mouth, tightness of the chest and tingling, heaviness and weakness of the hands may occur. Large doses may precipitate fits in epileptics. Allergy and anaphylaxis may occur. Blood dyscrasias, including agranulocytosis and haemolytic anaemia may occur. The effects of atropine and tricyclic antidepressants may be enhanced by triprolidine HCl. Triprolidine HCl may mask the warning symptoms of damage caused by ototoxic drugs and may affect the metabolism of drugs in the liver. Lichenoid skin eruption due to triprolidine HCl has been reported.
Codeine may cause nausea, vomiting, constipation, drowsiness, confusion, dry mouth, sweating, facial flushing, vertigo, bradycardia, palpitation, orthostatic hypotension, hyperthermia, restlessness, changes of mood and miosis. Micturition may be difficult and there may be ureteric or biliary spasm. Raised intracranial pressure may occur. Other side-effects of codeine include antidiuretic effects, circulatory failure, deepening coma, confusion, drowsiness, euphoria, hypotension, muscle rigidity, pruritus, respiratory depression and urticaria. Codeine should be given with caution to patients with hypothyroidism, adrenocortical insufficiency, impaired liver function, prostatic hypertrophy or shock. It should be used with caution in patients with inflammatory or obstructive bowel disorders. The dosage should be reduced in elderly and debilitated patients. Codeine should be used with caution in patients with myasthenia gravis and impaired kidney function. Prolonged use of high doses of codeine has produced dependence.
Guaiphenesin may cause gastro-intestinal discomfort and may cause nausea and vomiting. it may interfere with diagnostic measurements of 5-hydroxy-indoleacetic acid and vanillylmandelic acid.
INTERACTIONS: ACUTUSSIVE EXPECT ADULT should be used with caution in patients taking other sympathomimetic agents, such as decongestants, appetite suppressants and amphetamine-like psycho-stimulants, or antihypertensive agents, as this may cause a rise in blood pressure largely because of interaction with pseudoephedrine HCl. The effect of a single dose of ACUTUSSIVE EXPECT ADULT on the blood pressure of these patients should be observed before recommending repeated or unsupervised treatment.
The antibacterial agent, furazolidone is known to cause a dose related inhibition of monoamine oxidase. ACUTUSSIVE EXPECT ADULT and furazolidone should not be taken together.
The effect of ACUTUSSIVE EXPECT ADULT due to pseudoephedrine HCl, are diminished by guanethidine, reserpine, methyldopa and may be diminished by tricyclic antidepressants.
The effect of atropine and tricyclic depressants may be enhanced by triprolidine HCl. Triprolidine may enhance the central nervous system sedative effects of alcohol, barbiturates, hypnotics, narcotic analgesics, sedatives and tranquillisers. Triprolidine HCl may mask the warning symptoms of damage caused by ototoxic agents.
The depressant effects of codeine are enhanced by depressants of the central nervous system such as alcohol, anaesthetics, hypnotics and sedatives, and phenothiazines.
Long term use of anticonvulsants and oral steroid contraceptives cause an increase in the first pass metabolism or clearance rate and may prevent attainment of therapeutic levels.
