Other Therapy for Psoriasis
Conventional therapy is one that has been tested with clinical trials or has other evidence of clinical effectiveness. The FDA has approved several drugs for the treatment of psoriasis as described above. Some patients look to alternative therapy, diet changes, supplements, or stress-reducing techniques to help reduce symptoms. For the most part, alternative therapies have not been tested with clinical trials, and the FDA has not approved dietary supplements for treatment of psoriasis. There are no specific foods to eat or to avoid (except for alcohol) for patients with psoriasis. However, some other therapies can be found on the National Psoriasis Foundation web site. Individuals should check with their doctors before starting any therapy.
Some medications purchased online, both oral and topical, may actually contain pharmaceuticals that would normally require a prescription. This becomes a problem with unanticipated medication side effects and interactions. Caution should always be exercised in purchasing and using such products.
If one is taking a systemic retinoid such as acitretin or covering large areas with a topical retinoid (tazorac) or a vitamin D analog (calcipotriene, calcitriol), he or she should be careful about taking "megadoses" of the same vitamins as a supplement. In such cases, vitamin toxicity can occur.
A variety of herbal therapies have been reported in the lay press and on the Internet to help psoriasis. Some of these are oral and some topical, but none have been shown to have any predictable benefit at this time. Some, such as tea tree oil, coconut oil, and primrose oil, are known to cause contact dermatitis, which can transform a bothersome plaque into an oozing, blistering, intensely itchy one. There is no good evidence to support use of apple cider vinegar or household cleaning products either.
