There are many effective treatment choices for psoriasis. The best treatment is individually determined by the treating physician and depends, in part, on the type of disease, the severity, and the total body area involved.

For mild disease that involves only small areas of the body (like less than 10% of the total skin surface), topical (skin applied) creams, lotions, and sprays may be very effective and safe to use. Occasionally, a small local injection of steroids directly into a tough or resistant isolated psoriasis plaque may be helpful.

For moderate to severe disease that involves much larger areas of the body (like 20% or more of the total skin surface), topical products may not be effective or practical to apply. These cases may require ultra-violet light treatments or systemic (total body treatments such as pills or injections) medications. Internal medications usually have greater risks.

Treatment In Brief

For psoriatic arthritis, systemic medications are generally required to stop the progression of permanent joint destruction. Topical therapies are not effective.

The treatment, which should be carried out in close collaboration between the patient and the GP or the dermatologist, consists of various treatments used locally on the skin and taken by mouth. It depends on the patient’s age, state of health and on the nature of the psoriasis.

Moisturisers are an important factor in treatment for psoriasis and may be all that is needed for mild psoriasis. They reduce dryness, cracking and scaling of the skin.

Specific local treatments include creams and ointments containing coal tar,dithranol, tazarotene (Zorac) or vitamin D-related compounds, eg calcipotriol (Dovonex), calcitriol (Silkis) or tacalcitol (Curatoderm)).

Occasionally, corticosteroid-containing ointments are used for a short time. Combining a corticosteroid with another topical treatment, either as separate products used at different times of day, or as a combination product, eg Dovobet (calcipotriol and betamethasone) or Alphosyl HC (coal tar and hydrocortisone), may be beneficial for chronic psoriasis vulgaris.

Special lotions are available for scalp treatment. These often contain salicylic acid, coal tar, sulphur or corticosteroids.

Phototherapy (ultraviolet B, UVB) and photochemotherapy (psoralent ultraviolet A, PUVA) are both used in specialist dermatology centres for widespread psoriasis. Many patients find that natural sunlight also helps.

Oral treatment with immunosuppressants such as ciclosporin (Neoral) ormethotrexate (eg Maxtrex) or the vitamin A derivative acitretin (Neotigason) may be used for patients with severe, widespread or unresponsive psoriasis.

Injections of the immunosuppressants etanercept (Enbrel), adalimumab (Humira)or infliximab (Remicade) may be used for people with severe plaque psoriasis that has failed to respond to ciclosporin, methotrexate or photochemotherapy, or for people who can’t take or tolerate these treatments.

Complete Psoriasis Treatments can be divided into three main types: topical treatments, light therapy and systemic medications.

Topical treatments

Used alone, creams and ointments that you apply to your skin can effectively treat mild to moderate psoriasis. When the disease is more severe, creams are likely to be combined with oral medications or light therapy. Topical psoriasis treatments include:

• Topical corticosteroids. These powerful anti-inflammatory drugs are the most frequently prescribed medications for treating mild to moderate psoriasis. They slow cell turnover by suppressing the immune system, which reduces inflammation and relieves associated itching. Topical corticosteroids range in strength, from mild to very strong. Low-potency corticosteroid ointments are usually recommended for sensitive areas, such as your face or skinfolds, and for treating widespread patches of damaged skin. Your doctor may prescribe stronger corticosteroid ointment for small areas of your skin, for persistent plaques on your hands or feet, or when other treatments have failed. Medicated foams and scalp solutions are available to treat psoriasis patches on the scalp. Long-term use or overuse of strong corticosteroids can cause thinning of the skin and resistance to the treatment’s benefits. To minimize side effects and to increase effectiveness, topical corticosteroids are generally used on active outbreaks until they’re under control.
• Vitamin D analogues. These synthetic forms of vitamin D slow down the growth of skin cells. Calcipotriene (Dovonex) is a prescription cream or solution containing a vitamin D analogue that may be used alone to treat mild to moderate psoriasis or in combination with other topical medications or phototherapy. This treatment can irritate the skin. Calcitriol (Rocaltrol) is expensive, but may be equally effective and possibly less irritating than calcipotriene.
• Anthralin. This medication is believed to normalize DNA activity in skin cells. Anthralin (Dritho-Scalp) can also remove scale, making the skin smoother. However, anthralin can irritate skin, and it stains virtually anything it touches, including skin, clothing, countertops and bedding. For that reason doctors often recommend short-contact treatment — allowing the cream to stay on your skin for a brief time before washing it off. Anthralin is sometimes used in combination with ultraviolet light.
• Topical retinoids. These are commonly used to treat acne and sun-damaged skin, but tazarotene (Tazorac, Avage) was developed specifically for the treatment of psoriasis. Like other vitamin A derivatives, it normalizes DNA activity in skin cells and may decrease inflammation. The most common side effect is skin irritation. It may also increase sensitivity to sunlight, so sunscreen should be applied while using the medication. Although the risk of birth defects is far lower for topical retinoids than for oral retinoids, your doctor needs to know if you’re pregnant or intend to become pregnant if you’re using tazarotene.
• Calcineurin inhibitors. Currently, calcineurin inhibitors — tacrolimus (Prograf) and pimecrolimus (Elidel) — are approved only for the treatment of atopic dermatitis, but studies have shown them to be effective at times in the treatment of psoriasis. Calcineurin inhibitors are thought to disrupt the activation of T cells, which in turn reduces inflammation and plaque buildup. The most common side effect is skin irritation. Calcineurin inhibitors are not recommended for long-term or continuous use because of a potential increased risk of skin cancer and lymphoma. Calcineurin inhibitors are used only with your doctor’s input and approval. They may be especially helpful in areas of thin skin, such as around the eyes, where steroid creams or retinoids are too irritating or may cause harmful effects.
• Salicylic acid. Available over-the-counter (nonprescription) and by prescription, salicylic acid promotes sloughing of dead skin cells and reduces scaling. Sometimes it’s combined with other medications, such as topical corticosteroids or coal tar, to increase its effectiveness. Salicylic acid is available in medicated shampoos and scalp solutions to treat scalp psoriasis.
• Coal tar. A thick, black byproduct of the manufacture of petroleum products and coal, coal tar is probably the oldest treatment for psoriasis. It reduces scaling, itching and inflammation. Exactly how it works isn’t known. Coal tar has few known side effects, but it’s messy, stains clothing and bedding, and has a strong odor. Coal tar is available in over-the-counter shampoos, creams and oils. It’s also available in higher concentrations by prescription.
• Moisturizers. By themselves, moisturizing creams won’t heal psoriasis, but they can reduce itching and scaling and can help combat the dryness that results from other therapies. Moisturizers in an ointment base are usually more effective than are lighter creams and lotions.

Light therapy (phototherapy)

As the name suggests, this psoriasis treatment uses natural or artificial ultraviolet light. The simplest and easiest form of phototherapy involves exposing your skin to controlled amounts of natural sunlight. Other forms of light therapy include the use of artificial ultraviolet A (UVA) or ultraviolet B (UVB) light either alone or in combination with medications.

• Sunlight. Ultraviolet (UV) light is a wavelength of light in a range too short for the human eye to see. When exposed to UV rays in sunlight or artificial light, the activated T cells in the skin die. This slows skin cell turnover and reduces scaling and inflammation. Brief, daily exposures to small amounts of sunlight may improve psoriasis, but intense sun exposure can worsen symptoms and cause skin damage. Before beginning a sunlight regimen, ask your doctor about the safest way to use natural sunlight for psoriasis treatment.
• UVB phototherapy. Controlled doses of UVB light from an artificial light source may improve mild to moderate psoriasis symptoms. UVB phototherapy, also called broadband UVB, can be used to treat single patches, widespread psoriasis and psoriasis that resists topical treatments. Short-term side effects may include redness, itching and dry skin. Using a moisturizer may help decrease these side effects.
• Narrowband UVB therapy. A newer type of psoriasis treatment, narrowband UVB therapy may be more effective than broadband UVB treatment. It’s usually administered two or three times a week until the skin improves, then maintenance may require only weekly sessions. Narrowband UVB therapy may cause more severe and longer lasting burns, however.
• Goeckerman therapy. Some doctors combine UVB treatment and coal tar treatment, which is known as Goeckerman treatment. The two therapies together are more effective than either alone because coal tar makes skin more receptive to UVB light. Once requiring a three-week hospital stay, a modification of the original treatment can be performed in a doctor’s office. Another method, the Ingram regimen, combines UVB therapy with a coal tar bath and an anthralin-salicylic acid paste that’s left on your skin for several hours or overnight.
• Photochemotherapy, or psoralen plus ultraviolet A (PUVA).Photochemotherapy involves taking a light-sensitizing medication (psoralen) before exposure to UVA light. UVA light penetrates deeper into the skin than does UVB light, and psoralen makes the skin more responsive to UVA exposure. This more aggressive treatment consistently improves skin and is often used for more-severe cases of psoriasis. PUVA involves two or three treatments a week for a prescribed number of weeks. Short-term side effects include nausea, headache, burning and itching. Long-term side effects include dry and wrinkled skin, freckles, and increased risk of skin cancer, including melanoma, the most serious form of skin cancer.
• Excimer laser. This form of light therapy, used for mild to moderate psoriasis, treats only the involved skin. A controlled beam of UVB light of a specific wavelength is directed to the psoriasis plaques to control scaling and inflammation. Healthy skin surrounding the patches isn’t harmed. Excimer laser therapy requires fewer sessions than does traditional phototherapy because more powerful UVB light is used. Side effects can include redness and blistering.
• Pulsed dye laser. Similar to the excimer laser, the pulsed dye laser uses a different form of light to destroy the tiny blood vessels that contribute to psoriasis plaques. Side effects can include bruising for up to 10 days after treatment. There is a slight risk of scarring.
• Combination light therapy. Combining UV light with other treatments such as retinoids frequently improves phototherapy’s effectiveness. Combination therapies are often used after other phototherapy options are ineffective.

Oral or injected medications

If you have severe psoriasis or it’s resistant to other types of treatment, your doctor may prescribe oral or injected drugs. Because of severe side effects, some of these medications are used for only brief periods and may be alternated with other forms of treatment.

• Retinoids. Related to vitamin A, this group of drugs may reduce the production of skin cells if you have severe psoriasis that doesn’t respond to other therapies. Signs and symptoms usually return once therapy is discontinued, however. Side effects may include dryness of the skin and mucous membranes, itching, and hair loss. And because retinoids such as acitretin (Soriatane) can cause severe birth defects, women must avoid pregnancy for at least three years after taking the medication.
• Methotrexate. Taken orally, methotrexate helps psoriasis by decreasing the production of skin cells and suppressing inflammation. It may also slow the progression of psoriatic arthritis in some people. Methotrexate is generally well tolerated in low doses, but may cause upset stomach, loss of appetite and fatigue. When used for long periods it can cause a number of serious side effects, including severe liver damage and decreased production of red and white blood cells and platelets.
• Cyclosporine. Cyclosporine suppresses the immune system and is similar to methotrexate in effectiveness. Like other immunosuppressant drugs, cyclosporine increases your risk of infection and other health problems, including cancer. Cyclosporine also makes you more susceptible to kidney problems and high blood pressure — the risk increases with higher dosages and long-term therapy.
• Hydroxyurea. This medication isn’t as effective as cyclosporine or methotrexate, but unlike the stronger drugs it can be combined with phototherapy. Possible side effects include a decrease in red blood cells (anemia) and a decrease in white blood cells and platelets. It should not be taken by women who are pregnant or planning to become pregnant.
• Immunomodulator drugs (biologics). Several immunomodulator drugs are approved for the treatment of moderate to severe psoriasis. They include alefacept (Amevive), etanercept (Enbrel), infliximab (Remicade) and ustekinumab (Stelara). These drugs are given by intravenous infusion, intramuscular injection or subcutaneous injection and are usually used for people who have failed to respond to traditional therapy or who have associated psoriatic arthritis. Biologics work by blocking interactions between certain immune system cells and particular inflammatory pathways. Although they’re derived from natural sources rather than chemical ones, they must be used with caution because they have strong effects on the immune system and may permit life-threatening infections. In particular, people taking these treatments must be screened for tuberculosis.
• Thioguanine. Nearly as effective as methotrexate and cyclosporine, this drug has fewer side effects. However, this drug is more likely to cause anemia, and women who are pregnant or planning to become pregnant must avoid it because it may cause birth defects.
