Oxsoralen is a medication that contains the active ingredient methoxsalen. It belongs to a class of medications known as psoralens and is primarily used in the treatment of certain skin conditions, such as psoriasis and vitiligo.

Oxsoralen is used as part of a treatment called PUVA therapy (psoralen plus ultraviolet A rays) for severe and most severe cases of psoriasis vulgaris in adults.

It helps to slow down the overgrowth of skin cells in psoriasis, leading to improvement in symptoms.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking methoxsalen and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Do not sunbathe for 24 hours before taking methoxsalen and having the UVA light treatment.

Take this medication by mouth with food or milk as directed by your doctor, usually 2 to 4 hours before your UVA light treatment. Taking methoxsalen with food helps to increase the absorption of the medication and decreases nausea.

The dosage of methoxsalen is based on your weight, medical condition, and response to treatment. The amount and time of UVA light for each treatment is based on your skin type and response to treatment. You may have UVA light treatments 2 to 4 times a week when you first start and then less often as your condition improves.

For 24 hours after taking the capsule, during daylight hours wear wrap-around sunglasses which block out UVA light. This will prevent UVA rays from entering the eyes. UVA light can cause methoxsalen to bind to the lenses of the eyes, causing cataracts. Also, avoid sunlight (including sunlight through windows) on your skin or lips for at least 8 hours after taking methoxsalen. This will prevent the body from getting too many UVA rays which could lead to sunburn. If you cannot avoid sunlight, wear protective clothing (such as a hat, gloves, long-sleeved shirt, and pants) and/or sunscreen which blocks out UVA light. Consult your doctor or pharmacist for information on which sunscreen to use. Do not apply sunscreen to areas of the skin affected by psoriasis/vitiligo until after the UVA light treatment.

During the UVA light treatment, follow all instructions given by the healthcare professional. After the UVA light treatment, do not sunbathe for at least 48 hours. Doing so may increase the risk of severe burns. Consult your doctor for more details.
