Vasoconstriction with resultant hypertension, reflex bradycardia, tachycardia, cardiac arrhythmias, anginal pain, palpitations, cardiac arrest, hypotension with dizziness and fainting, and flushing have also been reported.
Other effects that may occur with sympathomimetic agents include difficulty in micturition and urinary retention, dyspnoea, altered metabolism including disturbances of glucose metabolism, sweating and hypersalivation. Headache is also common.

SPECIAL PRECAUTIONS:
Codeine Phosphate should be given with caution or in reduced doses to patients with hypothyroidism, adrenocortical insufficiency, impaired kidney or liver function, prostatic hypertrophy or shock. Patients with obstructive bowel disorders and myasthenia gravis also need to be cautious when taking codeine phosphate.
Ephedrine Hydrochloride should be used with care in patients with hyperthyroidism, cardiovascular disease, occlusive vascular disorders, aneurysms, diabetes mellitus or closed-angle glaucoma.
Anginal pain may be precipitated in patients with angina pectoris. Ephedrine Hydrochloride should be avoided or used with caution in patients undergoing anaesthesia with halogenated anaesthetics and may cause an increased risk of arrhythmias in patients receiving cardiac glycosides, quinidine or tricyclic antidepressants.
Promethazine Hydrochloride should be used with care in patients with cardiovascular hepatic diseases, narrow angle glaucoma, urinary retention and prostatic hypertrophy. Promethazine may potentiate the hypotensive effect of some anti-hypertensives.

Excitation, convulsions, respiratory depression, hypotension, circulatory failure and deepening coma may occur. Overdose may be fatal, especially in children.
In the event of overdosage the stomach should be emptied by aspiration and lavage. Activated charcoal and laxatives may also be used.
