Trioxsalen
About Trioxsalen
Trioxsalen is a topical skin treatment used in combination with controlled ultraviolet light therapy to help restore skin color. It is primarily prescribed for skin conditions like vitiligo, where patches of skin lose their natural pigment, and sometimes psoriasis. Trioxsalen works by making your skin more sensitive to light, which helps stimulate the cells that produce your natural skin color.
For the best results, you must apply Trioxsalen consistently and exactly at the scheduled times before your light therapy sessions. Consistency is highly important, as skipping applications can delay the restoration of your skin's pigment. While using this treatment, making certain diet and lifestyle changes—such as avoiding natural sun exposure and eating antioxidant-rich foods—can support your skin's healing process.
While Trioxsalen is highly effective, it can cause mild side effects like skin redness, itching, or dryness. If you experience severe burning, blistering, or skin pain, you must stop using the product immediately and consult your doctor or pharmacist. Always talk to your doctor or pharmacist if you notice any unusual changes in your skin.
Talk to your doctor before starting Trioxsalen if you have any pre-existing health conditions, especially those related to light sensitivity. Do not use this if you have autoimmune conditions like lupus, porphyria, or a history of skin cancer, as these make your skin highly vulnerable to light damage.
Let your doctor know about any other medicines you are taking, as some can increase your risk of severe sunburns. If you are pregnant, breastfeeding, or elderly, talk to your doctor or pharmacist before starting treatment to ensure it is safe for your specific situation.

Patients Concern
Disease/Condition Glossary
Psoriasis: Psoriasis is a common, long-term (chronic) auto-immune disorder. It tends to go through cycles, flaring for a few weeks or months, then subsiding for a while or going into remission. Common signs and symptoms include red patches of skin covered with thick, silvery scales, small scaling spots (commonly seen in children), dry/cracked skin that may bleed or itch, itching, burning or soreness, thickened, pitted or ridged nails, swollen and stiff joints.
Vitiligo: Vitiligo is an auto-immune disease that causes loss of skin colour in patches. The discoloured areas usually get bigger with time. The condition can affect the skin on any part of the body. It can also affect the hair and the inside of the mouth. Symptoms include patchy loss of skin colour (which usually first appears on the hands, face, and areas around body openings and the genitals), premature whitening or greying of the hair (on your scalp, eyelashes, eyebrows or beard), loss of colour in the tissues that line the inside of your mouth and nose (mucous membranes). Causes of vitiligo are family history (heredity) and a trigger event such as stress, severe sunburn or skin trauma.
