Methoxsalen

In nature, methoxsalen is found in plants from the plant family Apiaceae. Chemically, methoxsalen is classified alongside other naturally occurring molecules known as furanocoumarins. Methoxsalen is utilized in the treatment of eczema, psoriasis, vitiligo, and select cutaneous lymphomas. Doctors use methoxsalen in concert with UVA lamplight as the methoxsalen adjusts the manner in which skin cells react to UVA radiation.

HOW TO USE:

Methoxsalen should be used exactly as directed by your doctor. There are no uniform dosage standards. Dosage and usage is entirely predicated by the age, health, skin type, and condition of the patient. Your doctor will decide your dosage. Oral methoxsalen is typically taken with milk or low fat foods one and a half to two hours prior to the patient's UVA treatment.

Patients taking methoxsalen should wear wrap-around sunglasses during daylight to keep UVA rays from getting into the eyes as UVA light can create a potential cataract danger if methoxsalen binds to the eye's lenses. Ask your doctor to explain the risks and cautionary procedures that are necessary when using this drug.
