Caring for your plaster cast

A plaster cast is applied to injured limbs to keep them from moving.

Follow these simple rules to care for your plaster cast.

Do not:
  • get it wet
  • walk on it unless told to by your doctor
  • try to remove it or alter it
  • put anything down the cast including powder, knitting needles, rulers especially if it becomes itchy.
  • elevate limb when resting
  • exercises as shown.


Special waterproof bags can be purchased from local chemists to cover your plaster.

Alternatively plastic garbage bags can be used with tape to seal the edges for showering


Elevate the affected limb for 1 hour if you experience any of the following symptoms:

  • swelling
  • pins and needles
  • numbness
  • changes in sensation
  • increased pain.

If there is no improvement, contact a health professional.

If you get your cast wet, or have an excessive smell from the cast, please contact the plaster room you attended.

Where to get help

  • Contact the hospital or health facility where you were given your cast.
  • See your doctor.
