Other Treatments for Psoriasis

Topical Treatments

The first step in psoriasis therapy is to apply treatment directly to the surface of the skin. This may involve the use of prescription or non-prescription topical therapies. The purpose of these treatments is to heal inflammation and reduce other symptoms of psoriasis. Non-prescription topical therapies that work on the skin include, but are not limited to:

Coal Tar

A remedy used for centuries, coal tar improves scaling, itching, and inflammation. It is very effective as a shampoo or oil for scalp psoriasis or on the skin. The treatment may be used by itself or in conjunction with ultraviolet light. Although improved, coal tar products may be messy.

Bath Solutions and Moisturizers

Keeping the skin moisturized with emollients is an important part of psoriasis treatment and will reduce itching and inflammation and promote flexibility. It is recommended that non-irritating moisturizing creams or ointments be applied on a regular basis. In addition, soaking in water will soothe skin. Healing can be enhanced by adding solutions to bath water, such as Dead Sea salts, oiled oatmeal, and Epsom salts.

Sunlight    TOP

Exposure to sunlight can suppress the immune system (activated T cells) in the skin, thus reducing inflammation and slowing the rapid growth of skin cells. People with mild-to-moderate psoriasis may benefit from short, daily doses of sunlight, while people with more extensive psoriasis may require ultraviolet light A (UVA) or ultraviolet light B (UVB) treatment in medically approved centers. (See phototherapy section below.) You should always check with your doctor or dermatologist before self-treating.

Phototherapy    TOP

Like natural sunlight, exposure to a certain wavelength of artificial ultraviolet light called ultraviolet light B (UVB) is effective for people with moderate to severe psoriasis or plaque areas that do not respond to other treatments. More severe psoriasis can be treated with ultraviolet light A (UVA) and a medication called psoralen. Psoralen is an oral or topical medication that makes the body more sensitive to light. This treatment is known as PUVA.

  • PUVA: This treatment is used for more widespread psoriasis (involving more than 10% of the skin) and commonly for psoriasis limited to hands and feet (bath or soak PUVA). The treatment combines UVA with psoralen. After a person is given psoralen either orally or topically, he/she is exposed to a carefully measured amount of UVA light. This treatment may require up to 25 exposures over a 2-3 month period before clearing occurs. PUVA treatments over a long period of time may increase the risk of skin aging, freckling, and skin cancer.

Most phototherapy is given 3-5 times per week for 1-3 months by using a light panel or light box at a clinic or in your doctor’s office. In certain cases, you may be able to use a light box or light panel in your home under your doctor’s guidance.

Excimer Laser

This type of laser is designed to produce ultraviolet radiation at a very specific wavelength. The excimer laser is used to treat small, resistant plaque areas of psoriasis.

Special Considerations    TOP

Your should get exercise and eat a heart healthy diet since psoriasis increases your risk of heart disease and type 2 diabetes.

Certain treatments may work well initially, but lose their effectiveness as your body develops resistance. Depending on your symptoms, your doctor may prescribe another type of treatment and continue trying new methods as needed to keep your psoriasis under control.

Dietary Changes    TOP

Obesity may be associated with increased severity of psoriasis. It may also make it more difficult to treat. Weight loss through dietary changes and regular exercise may help. Talk to a registered dietitian about weight loss methods and meal planning. Talk to your doctor before starting an exercise program.

When to Contact Your Doctor    TOP

Contact your doctor if:

  • Your symptoms are not improving with treatment
