- Cutaneous T-cell lymphoma⁚ This is a rare type of cancer affecting the skin. PUVA can help manage its symptoms.
How is Oxsoralen taken?
Oxsoralen comes in capsules and a lotion form. The capsules are typically taken 1-2 hours before exposure to UVA light, with food or milk to reduce nausea. The dosage depends on the patient’s weight and skin type.
