methoxsalen topical Uses
This medication is used along with controlled ultraviolet light (UVA) to cause a return in skin color in patients with a certain skin condition (vitiligo). Methoxsalen works by making the skin more sensitive to UVA light. This combination helps to increase the number of pigment-producing cells (melanocytes) in the skin.
This medication is not recommended for use in children younger than 12 years.How to use methoxsalen topical
This medication is applied by a health care professional to affected areas of the skin before your UVA light treatment.
The frequency of treatment is based on your medical condition and response to treatment.
After treatment with methoxsalen and UVA light, protect the treated area from sunlight (including sunlight through windows) for several days. This will prevent the treated area from getting too many UVA rays which could lead to sunburns. If you cannot avoid sunlight on the treated area, wear clothing over the area and/or sunscreen which blocks out UVA light. Consult your doctor or pharmacist for information on how long to protect the treated area and which sunscreen to use.
You may start to see improvement in your skin color after a few weeks of treatment but it may take 6 to 9 months to get the full benefit. Tell your doctor if your condition does not improve after 3 months or if it worsens.
