Very often, your doctor will detect guttate psoriasis by mere physical examination of the skin. He will look for raised red colored scaly rashes with well marked edges on your body. He would collect medical history of the patient to check whether he/she has been infected with strep throat, upper respiratory tract infection like tonsillitis earlier.
Often the person would have got infected two or three weeks before getting the psoriasis. He would also enquire about the list of medications like antimalarial drugs, beta-blockers and non-steroidal drugs the patient is currently taking.
If needed, your doctor will do a skin biopsy for testing it in the laboratory. In case of throat infection, culture is done for checking the presence of bacteria. Guttate psoriasis is largely seen in winter and gets reduced during summer.
Guttate Psoriasis Treatment
Often, no treatment is required for guttate psoriasis unless the person has severe itching and burning rashes. The purpose of treatment is to provide relief from the symptoms and to prevent further infection. Antibiotics are prescribed for managing infection like sore throat. Anti-itch creams that contain cortisone are useful in controlling itching. You can also use creams or lotions that contain coal tar.

Creams that contain corticosteroids are effective in managing itching and for suppressing the immune’s system response. In case the doctor suspects strep infection he may prescribe antimicrobial drugs like Amoxicilin or erythromycin.
Guttate lesions can be managed by psoralen based ultraviolet A radiation also known as PUVA. This is possible by mast cell activation for destroying guttate lesions. Either narrowband UV therapy or PUVA is administered for treating severe lesions. PUVA therapy will destroy the excess of skin growth thereby clearing guttate psoriasis on the palms and feet. However in some cases PUVA therapy may produce side effects like vomiting, itching and hypo-pigmentation effect.

This protein cells act by blocking specific kind of proteins (TNF alpha) thereby reduces the psoriasis to large extent. To some extent, exposure of the affected skin to sunlight will reduce the psoriasis gradually since sunlight contains both ultraviolet A and B. Do not overexpose the body to sunlight causing sunburn. You need to cover the unaffected areas by sunscreen lotion while taking sunbath.
FDA has approved excime laser for treating guttate psoriasis which would produce high frequency ultraviolet B. Mild to moderate type of psoriasis can be treated by this method. Pulsed dye laser is administered for destroying tiny blood vessels that induce formation of lesions. To achieve the desired effect 4-6 sessions of 30 minutes each should be taken.
