<unk>  has been associated with the following side effects: Very common (>10% frequency): * Accommodation defect * Blurred vision * Nausea * Dry mouth (Xerostomia) * Constipation * Fatigue * Weight gain * Increased appetite * Dizziness * Tremor * Headache * Myoclonus * Drowsiness * Somnolence * Restlessness * Micturition disorder * Sexual dysfunction (erectile dysfunction and loss of libido) * Hyperhidrosis (profuse sweating) Common (1–10% frequency): * Weight loss * Orthostatic hypotension * Sinus tachycardia *<unk> nically irrelevant ECG changes (e.g. T- and ST-wave changes) in patients of normal cardiac status * Palpitations * Tinnitus (hearing ringing in one's ears) * Mydriasis (dilated pupils) * Vomiting * Abdominal disorders * Diarrhoea * Decreased appetite * Increased transaminases * Increased Alkaline phosphatase * Speech disorders * Paraesthesia * Muscle hypertonia * Dysgeusia * Memory impairment * Muscular weakness * Disturbance in attention * Confusional state * Disorientation * Hallucinations (particularly in elderly patients and patients with Parkinson's disease) * Anxiety * Agitation * Sleep disorders * Mania * Hypomania * Aggression * Depersonalisation * Insomnia * Nightmares * Aggravation of depression * Delirium * Galactorrhoea (lactation that is not associated with pregnancy or breastfeeding) * Breast enlargement * Yawning * Yawn-induced orgasm * Hot flush * Dermatitis allergic (skin rash, urticaria) * Photosensitivity reaction * Pruritus (itching) Uncommon (0.1–1% frequency): * Convulsions * Ataxia * Arrhythmias * Elevated blood pressure * Activation of psychotic symptoms Very rare (<0.01% frequency): * Pancytopaenia — an abnormally low amount of all the different types of blood cells in the blood (including platelets, white blood cells and red blood cells). * Leukopenia — a low white blood cell count. * Agranulocytosis — a more severe form of leukopenia; a dangerously low neutrophil count which leaves one open to life-threatening infections due to the role of the white blood cells in defending the body from invaders. * Thrombocytopenia — an abnormally low amount of platelets in the blood which are essential to clotting and hence this leads to an increased tendency to bruise and bleed, including, potentially, internally. * Eosinophilia — an abnormally high number of eosinophils — the cells that fight off parasitic infections — in the blood. * Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) — a potentially fatal reaction to certain medications that is due to an excessive release of antidiuretic hormone — a hormone that prevents the production of urine by increasing the reabsorption of fluids in the kidney — this results in the development of various electrolyte abnormalities (e.g. hyponatraemia low blood sodium, hypokalaemia low blood potassium, hypocalcaemia low blood calcium). * Glaucoma * Oedema (local or generalised) * Alopecia (hair loss) * Hyperpyrexia (a high fever that is above 41.5 °C) * Hepatitis (liver swelling) with or without jaundice — the yellowing of the eyes, the skin, and mucous membranes due to impaired liver function. * Abnormal ECG * Anaphylactic and anaphylactoid reactions including hypotension * Neuroleptic malignant syndrome (NMS) — a potentially fatal side effect of antidopaminergic agents such as antipsychotics, tricyclic antidepressants and antiemetics (drugs that relieve nausea and vomiting). NMS develops over a period of days or weeks and is characterised by the following symptoms: * Tremor * Muscle rigidity * Mental status change (such as confusion, delirium, mania, hypomania, agitation, coma, etc.) * Hyperthermia (high body temperature) * Tachycardia (high heart rate) * Blood pressure changes * Diaphoresis (sweating profusely) * Diarrhoea * Alveolitis allergic (pneumonitis) with or without eosinophilia * Purpura * Conduction disorder (e.g. widening of QRS complex, prolonged QT interval, PR/PQ interval changes, bundle-branch block, torsade de pointes, particularly in patients with hypokalaemia)
