This glossary defines commonly used dermatitis terms, including products and medications used in the treatment of dermatitis and other skin conditions that co-exist with dermatitis, such as acne, rosacea, eczema, and psoriasis.
Neurodermatitis: occurs because of repeated scratching, may appear as small, and flat areas (plaques) of various sizes, 1 to 10 inches (2.5 to 25 centimeters) in diameter. These areas have definite margins that have become thick and leatherlike (lichenified). This type of dermatitis is also known as lichen simplex chronicus can occur when something such as a tight garment rubs or scratches your skin. This irritation may lead you to rub or scratch your skin repeatedly. Common locations include ankles, wrist, outer forearm or arm, and the back of your neck.
Nickel Allergy Dermatitis: allergic or irritant dermatitis resulting from contact with nickel
Nicotinamide Papulex®: (Pharmagenix) Gel, nicotinamide 4%. A topical treatment for inflammatory acne vulgaris
Nizoral®: a cream which contains as its active ingredient ketoconazole which is an antifungal preparation. It is used to treat sebborrheic dermatitis with the rationale that sebborrheic dermatitis is caused by a fungus which lives on everyone's skin and is normally non-pathological.
Nodules: solid, raised bumps on the skin, greater than 10 millimeters in diameter
Non-Comedogenic: (pronounced non-coh-me-dough-jen-ic) refers to anything that will not clog pores or produce comedones, commonly called blackheads
Non-contagious: incapable of being transmitted from person to person.
Noritate: a topical treatment for rosacea which works due to the anti-inflammatory action of Metronidazole (an antibiotic) which is its active ingredient. Noritate is meant to help reduce the spots and redness of rosacea through its anti-inflammatory action. Thus it may help to control rosacea, but not cure it. Metronidazole is also the active ingredient in Rozex gel, Metro cream and Metrolotion, but Noritate is less irritating. Its name is short for "no-irritate" (non-irritating).
Novodoxylin®: An oral antibiotic which is used to treat a wide variety of bacterial infections. It is often prescribed for rosacea. Also sold under the brand name(s): Vibra-Tabs®, Vibramycin®, Monodox®, Doxycycline®, Doryx®
Nummular Dermatitis: (Discoid Dermatitis) "discoid" or "nummular" dermatitis, which means coin or disc-shaped patches which commonly occur on the lower leg. They can be several centimetres across, or as small as two millimetres. The skin between the patches is usually normal, but may be dry and irritable. Discoid eczema may be extremely itchy, or scarcely noticeable.
Nutracort ®: (Hydrocortisone) a low potency steroid. Also sold under the brand name(s): Anusol-HC®, Hytone®, Cetacort®, Cortaind®, Locoid®, Cort-Dome®, Cortenema®, Cortifoam®, Lanacort®, Westcort®
