What are the side effects of ultraviolet light therapy

Many people are not aware of ultraviolet light therapy. In fact, it is a physical therapy that can be used to treat skin diseases such as vitiligo. Ultraviolet light therapy is very simple to treat, but you still need to be aware of the side effects of ultraviolet light therapy, especially for people who are allergic to ultraviolet light therapy.

1. It depends on the situation

Everyone's condition is different, so the specific treatment is also different. It is recommended that patients should first check clearly before treatment and then determine the specific treatment method. Do not use medication blindly to avoid causing the spread of white spots. There are many vitiligo drugs, but they all have certain indications and are not necessarily suitable for every patient. Therefore, it is recommended that patients should comprehensively check the specific causes of the disease before conducting targeted treatment. It is recommended that patients should go to a specialist hospital for treatment as soon as possible.

2. Itching

Most patients who undergo phototherapy will experience varying degrees of local skin itching after irradiation. Patients are advised to use topical moisturizing creams to prevent skin dryness, or hormonal ointments, or immunomodulators such as tacrolimus after irradiation.

3. Erythema

Compared with drugs, ultraviolet phototherapy has milder side effects. The most common ones are local skin erythema, pain and other sunburn-like reactions caused by excessive exposure dose or high exposure frequency. If sunburn occurs, irradiation can be suspended and treatment can be resumed after the erythema subsides. If more severe erythema occurs, topical nonsteroidal anti-inflammatory drugs or corticosteroids can be used. If blisters appear, you can go to the outpatient clinic to consult a doctor and continue treatment after local treatment and improvement.
