Questions & Answers

Side Effects & Adverse Reactions

 
SKIN BURNS
 
Serious skin burns from either UVA or sunlight (even through window glass) can result if recommended exposure schedule is exceeded and/or protective covering or sunscreens are not used. The blistering of the skin sometimes encountered after UV exposure generally heals without complication or scarring. (Farrington Daniels, Jr., M.D., personal communication). Suitable covering of the area of application or a topical sunblock should follow the therapeutic UVA exposure.
 
CARCINOGENICITY
 
Animal Studies. Topical methoxsalen has been reported to be a potent photocarcinogen in certain strains of mice. (Pathak et al 1959) 5.
 
Human Studies. None of our clinical investigators reported skin cancer as a complication of topical treatment for vitiligo. However, it is recommended that caution be exercised when the patient is fair-skinned, has a history of prior coal tar UV treatment, or has had ionizing radiation or taken arsenical compounds. Such patients who subsequently have oral psoralen – UVA treatment (PUVA) are at increased risk for developing skin cancer.
 
CONCOMITANT THERAPY
 
Special care should be exercised in treating patients who are receiving concomitant therapy (either topically or systemically) with known photosensitizing agents such as anthralin, coal tar or coal tar derivatives, griseofulvin, phenothiazines, nalidixic acid, halogenated salicylanilides (bacteriostatic soaps), sulfonamides, tetracyclines, thiazides and certain organic staining dyes such as methylene blue, toluidine blue, rose bengal, and methyl orange.
