Nickel Sulfate, Potassium Bromide, and Fumaric Acid

INDICATIONS PSORIZIDE ® Forte is indicated for the treatment of contact dermatitis due to nickel (metal/jewelry allergy,) dyshidrotic hand/foot eczema, and mild to severe psoriasis. It has been found to work well with a variety of combination therapies. Eczema, seborrhea and a variety of chronic pruritic inflammatory dermatoses generally respond well also.

Although there are no known contraindications, patients who are allergic to any PSORIZIDE ® Forte ingredient should consult a physician prior to taking the medication. (Refer to Section on Hypersensitivity )

Do not use if imprinted seal under bottle cap is missing or broken. Do not use if pregnant or nursing. If allergic to nickel or metal objects such as jewelry, see PRECAUTIONS for hypersensitivity information. Lactose intolerant patients may have gastrointestinal difficulty. This has very rarely been reported at the doses used.

Carefully adjust dosage to weight when treating young children. Use cautiously in setting of kidney disease. (see Dosage and Administration ) If skin rash appears or if nervous symptoms persist, recur frequently, or are unusual, discontinue use. Hypersensitivity Caution should be used when administering to patients with a history of contact sensitivity to nickel (common metal exposure). Nickel allergy may be confirmed by a positive nickel patch test. Most patients with positive nickel allergy history or a positive nickel patch test do not have any untoward reaction to administration of PSORIZIDE ® Forte. However, if there is a history of nickel sensitivity, begin with a very low dose and slowly increase over a period of six weeks as tolerated. Progressive G.I. absorption allows desensitization to occur. 8 Nickel desensitization schedule: Week Amount of Time to Take Medication Prior to Breakfast Week 1 1 tablet With Breakfast Week 2 1 tablet 15 min Prior Week 3 1 tablet 30 min Prior Week 4 1 tablet 45 min Prior Week 5 1 tablet 1 hour Prior Week 6 and thereon 2 tablets 1 hour Prior If new pruritic rashes occur or persist, discontinue PSORIZIDE ® Forte and treat appropriately. Do not use if there is a history of extra-cutaneous hypersensitivity to nickel or any ingredient in PSORIZIDE ® Forte. Information for patients Patients using PSORIZIDE ® Forte should receive the following information and instructions: This medication is to be used only as directed by a physician. It is important to take orally at the beginning of the day on an empty stomach (or any convenient time after having taken nothing but water for at least 7 hours) and to eat or drink nothing but water for one hour afterwards to avoid interference with absorption. Drug Interactions There are no known drug interactions. Carcinogenesis, mutagenesis, and impairment of fertility No studies have been done on the carcinogenesis, mutagenesis, or impairment of fertility of PSORIZIDE ® Forte. No carcinogenesis or mutagenesis has been reported in multiple animal studies for oral administration of fumaric acid and soluble nickel and bromide salts (active ingredients) even at very high doses. 24-27 Effects of fumaric acid It is not listed as a carcinogen by ACGIH, IARC, NIOSH, NTP, or OSHA. 26 It is a GRAS substance (generally recognized as safe) and is commonly used in food processing. Effects of soluble potassium bromide KBr is not listed as a carcinogen by the NTP, IARC, and OSHA. 28 Effects of soluble nickel sulphate Studies on experimental animals have never indicated that nickel, at any dose, is a carcinogen when introduced to the body orally. Furthermore, Nickel sulphate and other highly water soluble nickel salts, have never been known to induce carcinogenesis via any route of introduction including: oral, inhalation, cutaneous, IM, or IP. 10-12,27 No adverse effects were noted on fertility or reproduction in a 3-generational study of albino Wistar rats fed up to 1000 ppm Ni per day, which is equivalent to 50 mg/kg body weight per day Ni. 27 Pregnancy Pregnancy category C Animal reproduction studies have not been conducted with PSORIZIDE ® Forte. PSORIZIDE ® Forte should not be given to a pregnant woman. Nursing mothers It is not known whether this drug is secreted in human milk. However, since many drugs are secreted in human milk, caution should be exercised when PSORIZIDE ® Forte is administered to a nursing woman.
