How Do You Spell PHOTOTOXICITY?

1. Phototoxicity is a medical term that refers to a condition wherein a particular substance or medication becomes toxic or harmful to the skin or eyes when exposed to ultraviolet (UV) radiation from sunlight or artificial light sources. This reaction can occur when the skin or eyes are exposed to the substance and subsequently exposed to UV rays, leading to an exaggerated and often severe adverse reaction.

   The harmful effects of phototoxicity can vary and may include symptoms such as severe sunburn, blistering, swelling, itching, rash, or stinging sensation in the affected area. This reaction typically occurs within hours of exposure to sunlight or bright light sources, and the severity of symptoms often depends on various factors including the individual's sensitivity, duration and intensity of exposure, as well as the concentration and potency of the substance involved.

   Certain medications and substances are commonly associated with phototoxicity, including some antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), antidepressants, diuretics, and certain fragrances or plant extracts. Individuals taking these medications or using these substances should be cautious of sun exposure and potential light sources, as the combination can lead to adverse effects.

   Prevention and treatment of phototoxic reactions involve avoiding exposure to sunlight and other light sources, using broad-spectrum sunscreen to protect the skin, wearing protective clothing and eyewear, and seeking shade during peak sunlight hours. In cases where phototoxicity has already occurred, treatment may involve the use of topical creams or ointments, oral antihistamines, and in severe cases, medical intervention may be necessary to alleviate symptoms and prevent complications.
