What are the treatment options available for Psoriasis?

Coming to the treatments of psoriasis, there are many effective treatment choices. The best treatment is determined by the doctor you consult and if you do not have a doctor in mind, visit us at Ambrosia Clinics and we will help you control the condition. The treatment also depends on the type of psoriasis which a person is suffering from, the severity and also the area of the skin involved.

If the disease is mild, it mainly involves only small portions of the body which is less than 10% of the total skin surface, topical treatments such as creams, lotions, and sprays, might be effective and also safe to use only if suggested by the dermatologist.

When it comes to the more moderate or even to the severe form of the disease which involves much larger areas of the body, greater than 10% or more of the total skin surface, then topical treatment might not be effective. In this situation, ultraviolet light treatments, biological or oral medication is prescribed

All in all you must know that with any kind of medical condition, each and every medicine carry possible side effects. No kind of medication is 100% effective or 100% safe for everyone either. The decision to take up any kind of medication requires thorough diagnosis and discussion with your doctor. The benefits and risks of any kind of treatment needs to be considered for each and every type of psoriasis and of course, the patient.

Looking at the treatments, here are the most commonly used treatments for psoriasis:

Topical medications:

Topical corticosteroids are highly effective and is often used as initial treatment for limited or small areas of skin affected with psoriasis. The corticosteroids can come in many preparations, including liquids, gels, creams, foams and ointments. Steroids mainly come and are prescribed in different strengths depending on the type of psoriasis.  Stronger preparations should be limited as overuse or prolonged use might cause problems like permanent skin thinning and damage which is called atrophy.

other therapeutically active topical agents licensed for psoriasis include, vitamin D analogues, tar, dithranol, and tazarotene (a retinoid).

Light Therapy:

Light therapy also called phototherapy is an effective treatment for psoriasis. There are several types of medical light therapies which are used as treatments that include PUVA(Psoralen UVA), UVB, and narrow-band UVB. These are artificial light sources which have been used for many years and generally are available at clinics where the physician practices treatment with this method.

Natural sunlight as it is a rich source of ultraviolet rays is also used to treat psoriasis. Short, controlled exposures to natural sunlight on an every alternative day basis might help or clear psoriasis for some patients. While using sunlight as a treatment, the unaffected area of the skin and other sensitive areas of the body such as the face and hands will need to be protected during the exposure.

There are also other newer light sources like lasers and photodynamic therapy which have been used to treat psoriasis such as:

PUVA:

PUVA is a special treatment for psoriasis using a photosensitizing drug and timed exposure of artificial light which are composed of ultraviolet light wavelengths in the UVA spectrum. The photosensitizing drug in PUVA is called psoralen. Both the psoralen and the UVA light needs to be given within one hour of each other for an appropriate response to occur. These treatments are usually given in a clinic and need to be two to three times per week.

Several weeks of PUVA treatment is required before you can see the significant results. The time of the light exposure is eventually increased through the course of the treatment. Psoralens can be taken as a pill or topically as well in the form of a bath or lotion. Patients who are given the treatment of PUVA are generally sensitive to the sun and must completely avoid sun exposure for a while after PUVA treatment.

There are however, a few side effects of this treatment. The common side effects with PUVA are burning and aging of the skin, increased number of brown spots called lentigines, there might also be an increased risk of skin cancer, including melanoma.

PUVA treatment need to be very closely monitored and stopped when the maximum number of treatments has been reached.

Narrow-band UVB phototherapy:

Narrow-band UVB phototherapy is also an artificial light treatment which includes the usage of very limited wavelengths of light. It is given two to three times per week depending on the severity of psoriasis. The dosage of UVB is based on time and exposure is gradually increased depending on the severity and also the toleration of the patient. The side effects of UVB treatment include the burning of skin, premature aging, and also an increased risk of skin cancer.

SYSTEMIC MEDICATION:

Oral Medication Like Methotrexate, Acitretin, cyclosporine and Biologics are prescribed depending on the type and severity of psoriasis.
