Visudyne

Visudyne (verteporfin) is a light-activated drug used in photodynamic therapy for certain eye conditions. It helps target abnormal blood vessels in the retina when exposed to specific light. This treatment is administered under medical supervision.

Visudyne is primarily used to treat eye conditions caused by abnormal blood vessel growth, such as wet age-related macular degeneration. It may also be used for conditions like pathological myopia or central serous retinopathy. The drug works when activated by a specific type of light during a medical procedure.

After administration, verteporfin circulates in the bloodstream and accumulates in abnormal blood vessels. When exposed to non-thermal red light, it becomes active and helps close off these vessels. Patients may experience temporary light sensitivity and should avoid direct sunlight or bright indoor lights for a period after treatment.

Visudyne should only be handled and administered by healthcare professionals in a controlled setting. Patients must avoid exposure to sunlight or bright indoor lights for several days post-treatment to prevent skin reactions. Inform your doctor of any allergies or medical conditions before receiving this medication.

Certain medications may interact with verteporfin, including those that increase light sensitivity or affect blood flow. Avoid herbal supplements like St. John’s wort, as they may alter the drug’s effectiveness. Always disclose all medications and supplements to your healthcare provider before treatment.
