What Is Photoallergy And What Substances Affect It?
Photoallergy is an immunological reaction produced by the interaction of light rays and certain chemicals. It is a form of contact allergic reaction where light is necessary to cause the sensitivity reaction. Hexachlorophene, sunscreen agents, topical antihistamines, and certain cleaning products are the primary photocontact allergies. If you are ever in doubt about your medication, please consult your physician and/or pharmacist for the photosensitivity of the medications you are taking (even if they are over the counter).
