Phototoxicity, also called photoirritation, is a chemically induced skin irritation, requiring light, that does not involve the immune system. [1] It is a type of photosensitivity . [ 1 ] [ 2 ]
Photosensitive drug reaction secondary to medications may cause phototoxic, photoallergic, and lichenoid reactions, and photodistributed telangiectasias, as well as pseudoporphyria. [ 1 ] : 121 Drugs involved include naproxen and doxycycline .
Photosensitivity is the amount to which an object reacts upon receiving photons, especially visible light.In medicine, the term is principally used for abnormal reactions of the skin, and two types are distinguished, photoallergy and phototoxicity.
Primary photodermatoses are immunology mediated or caused by chemical/drug exposure. An example of primary photodermatoses is Polymorphous light eruption. Polymorphous light eruption is the most common type of photodermatoses. It is most likely due to an abnormal immune system reaction to the sun.
Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure.
In medicine, a drug eruption is an adverse drug reaction of the skin. Most drug-induced cutaneous reactions are mild and disappear when the offending drug is withdrawn. [1] These are called "simple" drug eruptions. However, more serious drug eruptions may be associated with organ injury such as liver or kidney damage and are categorized as ...
A drug allergy is an allergy to a drug, most commonly a medication, and is a form of adverse drug reaction. Medical attention should be sought immediately if an allergic reaction is suspected. An allergic reaction will not occur on the first exposure to a substance.
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
