Cholinergic urticaria is the medial term for the skin rash commonly known as hives. It takes the form of swollen, pale, red bumps, patches, or welts on the skin.

Causes of Cholinergic Urticaria

Cholinergic urticaria or hives can be caused by either allergic reactions or through physical means such as exposure to heat, sweating, sun, or vibration.

Symptoms of Cholinergic Urticaria

A rash with intense itching, red skin, and swelling. Acute cases last up to six weeks while chronic cases last longer.

Treatment of Cholinergic Urticaria

Much like other allergies the best treatment for cholinergic urticaria is to identify, remove, and prevent the trigger. Avoiding hot water, wearing loose fitting clothing, and sleeping in a cool room can help.

Antihistamines can help alleviate the symptoms, but if that does not work then oral corticosteroids may be prescribed. If the reaction is severe an epinephrine (adrenaline) injection may be administered.
