Itching

Itching is an irritating sensation that makes you want to scratch or rub. It may affect one area or the whole body. Dry skin or a skin condition is often responsible, but itching can sometimes signal allergy, infection, parasites, a medicine reaction or liver, kidney or blood disease. Take extra care during pregnancy, or with breathlessness, swelling or rapidly worsening illness.

  • Itching is common and has many possible causes, from dry skin to underlying internal disease.
  • Localised itching more often points to a skin problem; generalised itching more often requires a broader assessment.
  • Scratching briefly relieves symptoms but can cause wounds, infection and thickened skin.
  • Do not use steroid cream for prolonged periods or randomly without a doctor's plan, or simply take supplements hoping to stop itching.
  • Call your GP for persistent itching; outside office hours, call HAP 9252 for urgent GP care. Call Ambulance 912 only for a threat to life.
