Call your doctor if you have symptoms of psoriasis, such as:

• Bright red areas of raised patches (plaques) that are covered with loose, silvery, scaling skin.
• Thick, crusted patches on the scalp.
• Tiny pits or yellowish discoloration in the nails, separation of the nail from the skin, or buildup of skin debris under the nail.
• Signs of developing bacterial infection. These include:
  • Increased pain, swelling, redness, tenderness, or heat.
  • Red streaks extending from the area.
  • A discharge of pus.
  • Fever of 100.4F or higher with no other cause.

If you are currently being treated for psoriasis, call your doctor if you:

• Have severe and widespread psoriasis and your skin is more irritated or inflamed than usual, especially if you have another illness.
• Are taking medicine for psoriasis and have serious side effects, such as vomiting, bloody diarrhea, chills, or fever.
