Side Effects

Side Effects

Are there any side effects of which I should be aware?


The medication used in the photopheresis treatment will make you more sensitive to sunlight for about 24 hours after the treatment.

For this reason, you must take some simple, very important precautions to protect your eyes and skin. (Without taking these precautions, you put yourself at risk for cataracts or serious sunburns.)

THERAKOS™ Photopheresis is not intended for patients with a history of light-sensitive disease, an allergy to psoralen compounds, or who lack a lens in either eye.

For 24 hours, you should

  • Avoid sunlight as much as possible—even indirect sunlight coming through a window
  • Wear sunscreen (no lower than SPF 15) when exposed to sunlight (outdoors or indoors)
  • Wear UVA-protective, full-coverage sunglasses when exposed to sunlight

Other possible side effects usually go away within a day. These could include

  • Fatigue
  • Temporary increase in itchiness
  • Fever or redness appearing 6 to 8 hours after treatment.

The side effects that were clearly related to THERAKOS™ Photopheresis treatments and that resolved in 1 day are

  • Fever
  • Worsening of skin redness
  • Blood pressure changes during treatment

There is a small risk for developing an infection around the needle puncture site.

Talk to your doctor about any concerns you may have about potential risks or side effects.
