By taking into account how your psoriasis affects you physically, emotionally, and socially, your dermatologist may be able to offer you a greater variety of treatment options.
Treatments
Before your dermatologist can decide on a treatment approach, he or she must first determine the severity of your psoriasis. This typically involves assessing the percentage of body surface area (BSA) affected, and should also take into account other aspects of the disease, such as the location of your lesions and the impact of psoriasis on your quality of life.
Everyone reacts differently to his or her condition. For example, someone with only a few small patches of psoriasis may be overwhelmed by the disease, especially if it occurs on a more vulnerable part of the body. On the other hand, someone whose psoriasis covers over 50% of his or her body may not be bothered by it and is able lead a normal life.
A new look at assessing disease severity
and how it affects your treatment options
Both the American Academy of Dermatology (AAD) and the National Psoriasis Foundation recommend that dermatologists also consider quality of life issues when determining disease severity and when developing a treatment plan. That's why it's important to tell your dermatologist about your physical symptoms as well as how your psoriasis affects you emotionally and socially. By taking all of these aspects into account, your dermatologist may be able to offer you a greater variety of treatment options.
Where do you fit into this newer treatment approach?
After a recent evaluation of the current severity criteria of mild, moderate, and severe psoriasis, the National Psoriasis Foundation recommended using a classification system that focuses on how people with psoriasis should be treated. This two-tiered approach categorizes patients based on whether they are candidates for localized therapies or candidates for systemic and/or phototherapy.
- Candidates for localized therapy have plaque psoriasis that is limited to a small area and affects less than 5% of the Body Surface Area (BSA).
- Candidates for systemic and/or phototherapy have plaque psoriasis that affects 5% or more of the BSA. Some may have less than 5% but the lesions are present on vulnerable areas such as the face, genitals, hands or feet. People who are not adequately controlled using localized therapies, or who are significantly impaired physically or mentally by their disease, are also potential candidates for systemic and/or phototherapy.
- Acitretin
- Cyclosporine
- Methotrexate
Phototherapy: artificial ultraviolet light, or a combination of ultraviolet light and medications
- UVB broadband and narrowband
- PUVA
- UVA plus psoralen

- Over-the-counter topicals
- Moisturizers
- Salicylic acid
- Coal tar preparations
- Prescription topicals
- Topical steroids
- Vitamin D analogs
- Topical retinoids
- Anthralin

Your dermatologist may prescribe localized treatments in combination or in sequence with systemic therapies or phototherapy. You may also be prescribed a biologic medicine, which is a different way to treat psoriasis.
In addition to these more traditional therapies, you may wish to explore alternative treatment approaches, such as meditation or acupuncture.
