Who should not receive verteporfin injection?

People who have porphyria or allergies to the ingredients in verteporfin injection should not use it. Pregnant or breastfeeding women should talk to their doctor about the risks associated with receiving verteporfin injection; parents of children with relevant eye problems should do the same. Certain drugs, including thiazide diuretics, calcium channel blockers, tetracyclines, grisefulvin, sulfonylureas, sulfonamides, phenothiazines, anticoagulants, mannitol, aspirin, formate, beta-carotene and dimethyl sulfoxide, may change how verteporfin works, so talk to your doctor about your current medications before your injection. Before deciding on verteporfin treatment, tell your doctor about any conditions or treatments you have or have had— especially current radiation therapy and liver, gallbladder or bile duct problems—as well as known allergies, current medications and supplements.
