Some patients may experience cholinergic signs and symptoms such as dry mouth, dizziness, blurred vision, dilatation of the pupils with loss of accommodation, photophobia, closed angle glaucoma (very rare), urinary disturbances (urinary emergency and retention), reduced bronchial secretions, transient bradycardia (followed by tachycardia, palpitation and arrhythmias), flushing and dryness of the skin, constipation, nausea and vomiting.
Other signs and symptoms may include hallucination, high temperature (due to decreased sweating) and confusion. These may occur in all patient groups although certain populations (children and the elderly) are more susceptible to anticholinergic toxicity.
