Urticaria – also known as hives, wheals, welts or nettle rash with or without surrounding erythematous flares. This is a skin reaction that causes bumps, raised patches, or both to suddenly appear on the skin. Urticaria can be acute or chronic, spontaneous or inducible.
Acute urticaria
If symptoms are mild and occur after exposure to an allergen or irritant, home remedies can usually soothe the itchiness until the rash disappears.
Chronic urticaria
A person with chronic urticaria may need to take antihistamines regularly until their symptoms resolve.
Drug Induced urticaria
It has been known to result in severe cardiorespiratory failure. The anti-diabetic Sulphonyl urea glimepiride, in particular, has been documented to induce allergic reactions manifesting as urticarial.
