Characteristics
  • Redness of the skin. Occurs when the blood capillaries near the skin surface are congested or dilated.1
  • Can vary from pink to dark red or violaceous.
  • Typically blanchable with pressure.
  • Often associated with skin inflammation but can also occur in absence of inflammation.

Causes/Etiology
  • Erythema can be caused by many triggering events or underlying conditions, including infections and skin diseases.1,2
  • In foslevodopa/foscarbidopa subcutaneous infusion pump users, erythema may be related to the catheter or the adhesive used in the device.3
