CONTRAINDICATIONS
Certain underlying medical conditions contraindicate THERAKOS CELLEX Photopheresis, including:
Patients who cannot tolerate extracorporeal volume loss during the leukocyte enrichment phase
Patients exhibiting idiosyncratic or hypersensitivity reactions to 8-methoxypsoralen/psoralen compounds
Patients with coagulation disorders or who have had previous splenectomy
WARNINGS & PRECAUTIONS
THERAKOS CELLEX Photopheresis treatments should always be performed in locations where standard medical emergency equipment is available. Volume replacement fluids and/or volume expanders should be readily available throughout the procedure.
MR-Unsafe: Do not expose the device to a magnetic resonance (MR) environment. The device may present a risk of projective injury, and thermal injury and burns may occur. The device may generate artifacts in the MR image, or may not function properly.
Thromboembolic Events: Thromboembolic events, including pulmonary embolism and deep vein thrombosis, have been reported in the treatment of Graft versus Host Disease (GvHD), an indication not approved in Canada. Special attention to adequate anticoagulation is advised when treating patients with GvHD.
Concomitant Therapy: When prescribing and administering THERAKOS CELLEX Photopheresis for patients receiving concomitant therapy, exercise caution when changing treatment schedules to avoid increased disease activity that may be caused by abrupt withdrawal of previous therapy.
ADVERSE REACTIONS
Hypotension may occur during any treatment involving extracorporeal circulation. Monitor the patient closely during the entire treatment.
Transient pyretic reactions, 37.7-38.9 °C (100-102 °F), have been observed in some patients within 6-8 hours of reinfusion of the photoactivated leukocyte-enriched blood. A temporary increase in erythroderma may accompany the pyretic reaction.
Treatment frequency exceeding labeling recommendations may result in anemia.
Venous access carries a small risk of infection and pain.

SERIOUS WARNINGS & PRECAUTIONS
Concomitant Therapy: Exercise care in treating patients who are receiving concomitant therapy (either topically or systemically) with known photosensitizing agents.
Carcinogenicity: Oral administration of methoxsalen followed by cutaneous UVA exposure (PUVA therapy) is carcinogenic. Patients exhibiting multiple basal cell carcinomas or having a history of basal cell carcinoma should be diligently observed and treated.
Teratogenicity: Methoxsalen may cause fetal harm when given to a pregnant woman. Women undergoing photopheresis should be advised to avoid becoming pregnant.
Cataractogenicity: Patients should be told emphatically to wear UVA absorbing, wrap-around sunglasses for twenty-four (24) hours after methoxsalen treatment, any time they are exposed to direct or indirect sunlight and whether they are outdoors or exposed through a window.
Safety in children has not been established.
