4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

No formal reporting has been made about the undesirable effects of low-dose levomepromazine formulations; therefore, adverse effects cannot be ranked by frequency. Most available data on adverse effects are related to application of higher doses, i.e., ≥ 25 mg. Adverse effects that are more frequent and indicate the need for medical attention are as follows:

  • Dystonic extrapyramidal effects (spasms of eye, face, neck and back muscles)
  • Akathisia (motor restlessness)
  • Hypotension
  • Ocular changes including deposition of opaque material in lens and cornea, epithelial keratopathy or pigmentary retinopathy (blurred vision; defective colour vision; difficulty seeing at night)
  • Parkinsonism-like extrapyramidal effects (rigidity and tremor)
  • Tardive dyskinesia (unusual facial expressions or body positions, increased blinking or spasms of eyelid, uncontrolled twisting movements of neck, trunk, arms, or legs).

Hypotension is more frequent in the elderly and at the beginning of treatment, especially if high doses are used. Parkinsonian effects and tardive dyskinesia also occur more frequently in the elderly, whereas dystonia occurs more often in younger patients. Extrapyramidal effects may be dose-related and may decrease with a decrease in dosage. Ocular changes occur more frequently with high-dose or long-term use of phenothiazines.

Less frequent AEs include difficulty in urinating, photosensitivity (may cause severe sunburn), skin rash associated with contact dermatitis or cholestatic jaundice.

With rare incidence the following AEs may occur:

  • Blood dyscrasias including agranulocytosis leukocytopenia or thrombocytopenia (Agranulocytosis can develop within the first 3 months of treatment, with recovery within 1 to 2 weeks after medication is discontinued; it may recur upon rechallenge in recovered patients.)
  • Melanosis (Skin pigmentation changes in melanosis occur on exposed areas of the body and may fade after discontinuation of the drug.)
  • Neuroleptic malignant syndrome (NMS may occur at any time during neuroleptic therapy and is potentially fatal. It is most commonly seen within the first month of therapy, after the patient has switched from one neuroleptic to another, or after a dosage increase.)
  • Obstipation or paralytic ileus
  • QT prolongation and torsades de pointes
  • Seizures
  • Dark urine (Dark urine usually is caused by the presence of phenothiazine metabolites in the urine.)
  • Significant fever, and temperature regulation dysfunction. (Significant fever not attributable to any other cause may represent an idiosyncratic reaction. Levomepromazine may cause hypothermia in cold weather, since the disruption of the thermoregulatory mechanisms results in a poikilothermic state. Heatstroke caused by phenothiazine-induced suppression of temperature regulation in the hypothalamus may occur in environmental conditions of high heat and high humidity).
  • Jaundice may appear about 2 weeks after severe pruritus and may progress to chronic active hepatitis.

In the only double blind, randomised, controlled trial of low-dose levomepromazine (6.25mg once or twice daily), the most frequent side effects were

  • Drowsiness (20.4%)
  • Fatigue (16.3%)
  • Constipation (12.2%)
  • Headache, hypotension, and dry mouth (each 8.2%).

Additional side effects included dyspepsia, hypertension, diarrhoea, bruising (each 6.1%), dizziness, bowel colic, blurred vision (each 4.1%), confusion, sensitivity to light, palpitations, and jaundice (each 2.0%). Side effects worse than baseline were minimal, specifically those relating to extrapyramidal reactions.

If any of these side effects get serious, or if you notice any side effects not listed in this leaflet, please tell your doctor.
