Full Prescribing Information
Indications & Usage
III. INDICATIONS AND USAGE Photochemotherapy (Methoxsalen with long wave UVA radiation) is indicated for the symptomatic control of severe, recalcitrant, disabling psoriasis not adequately responsive to other forms of therapy and when the diagnosis has been supported by biopsy. Methoxsalen is intended to be administered only in conjunction with a schedule of controlled doses of long wave ultraviolet radiation.
Dosage & Administration
IX. DRUG DOSAGE & ADMINISTRATION CAUTION: Methoxsalen Capsules, USP represents a new dose form of methoxsalen. This new dosage form of methoxsalen exhibits significantly greater bioavailability and earlier photosensitization onset time than previous methoxsalen dosage forms. Each patient should be evaluated by determining the minimum phototoxic dose (MPD) and phototoxic peak time after drug administration prior to onset of photochemotherapy with this dosage form. Human bioavailability studies have indicated the following drug dosage and administration directions are to be used as a guideline only. PSORIASIS THERAPY 1. DRUG DOSAGE -INITIAL THERAPY: Methoxsalen capsules should be taken 1-1/2 to 2 hours before UVA exposure with some low-fat food or milk according to the following table: Patient's Weight Dose (kg) (lbs) (mg) <30 <66 10 30-50 66-110 20 51-65 112-143 30 66-80 146-176 40 81-90 179-198 50 91-115 201-254 60 >115 >254 70 Geriatric patients should generally be started at the low end of the dose recommended according to body weight and closely monitored during PUVA therapy. Although clinical experience has not identified differences in response between elderly and younger pati…
Warnings
V. WARNINGS - GENERAL A. SKIN BURNING: Serious burns from either UVA or sunlight (even through window glass) can result if the recommended dosage of the drug and/or exposure schedules are exceeded. B. CARCINOGENICITY: ANIMAL STUDIES: Topical or intraperitoneal methoxsalen has been reported to be a potent photocarcinogen in albino mice and hairless mice (Hakim et al., 1960 10 ). However, methoxsalen given by the oral route to Swiss albino mice suggests this agent exerts a protective effect against ultraviolet carcinogenesis; mice given 8-methoxypsoralen in their diet showed 38% ear tumors 180 days after the start of ultraviolet therapy compared to 62% for controls (O'Neal et al., 1957 11 ). HUMAN STUDIES: A 5.7 year prospective study of 1380 psoriasis patients treated with oral methoxsalen and ultraviolet A photochemotherapy (PUVA) demonstrated that the risk of cutaneous squamous-cell carcinoma developing at least 22 months following the first PUVA exposure was approximately 12.8 times higher in the high dose patients than in the low dose patients (Stern et al., 1979 12 , Stern et al., 1980 13 , and Stern et al., 1984 14 ). The substantial dose-dependent increase was observed in pat…
Contraindications
IV. CONTRAINDICATIONS A. Patients exhibiting idiosyncratic reactions to psoralen compounds. B. Patients possessing a specific history of light sensitive disease states should not initiate methoxsalen therapy except under special circumstances. Diseases associated with photosensitivity include lupus erythematosus, porphyria cutanea tarda, erythropoietic protoporphyria, variegate porphyria, xeroderma pigmentosum, and albinism. C. Patients with melanoma or with a history of melanoma. D. Patients with invasive squamous cell carcinomas. E. Patients with aphakia, because of the significantly increased risk of retinal damage due to the absence of lenses.

Adverse Reactions
VII. ADVERSE REACTIONS: A. METHOXSALEN: The most commonly reported side effect of methoxsalen alone is nausea, which occurs with approximately 10% of all patients. This effect may be minimized or avoided by instructing the patient to take methoxsalen in milk or food, or to divide the dose into two portions, taken approximately one-half hour apart. Other effects include nervousness, insomnia, and depression. B. COMBINED METHOXSALEN/UVA THERAPY: PRURITUS: This adverse reaction occurs with approximately 10% of all patients. In most cases, pruritus can be alleviated with frequent application of bland emollients or other topical agents; severe pruritus may require systemic treatment. If pruritus is unresponsive to these measures, shield pruritic areas from further UVA exposure until the condition resolves. If intractable pruritus is generalized, UVA treatment should be discontinued until the pruritus disappears. ERYTHEMA: Mild, transient erythema at 24-48 hours after PUVA therapy is an expected reaction and indicates that a therapeutic interaction between methoxsalen and UVA occurred. Any area showing moderate erythema (greater than Grade 2 - See Table 1 for grades of erythema) should b…
