Medications for Anal Itching
Itchy anus - NHS
Anal itching, medically known as pruritus ani, is a common dermatological problem affecting both men and women, although it is more common in men. It can occur at any age but seems to be most prevalent among people in the age bracket of 30 to 50 years. Pruritus ani is characterized by an excessively discomforting and often embarrassing itching or burning sensation of the skin around the anus rectal opening. This itch is sometimes so intense that it becomes almost impossible not to scratch. The incessant scratching, in turn, results in further skin irritation and damage and can even escalate the problem to a chronic stage, resulting in chronically inflamed and thickened skin called lichen simplex chronicus. Rigorous scratching, particularly at night when the patient is asleep, or abrasive vigorous scrubbing with toilet paper to relieve the itch after urination or a bowel movement can cause tiny ruptures in the affected skin. As a result of this additional trauma to the anal skin, occasional bleeding occurs when wiping after a bowel movement.
Your doctor may be able to diagnose the cause of your itching simply by asking you questions about your symptoms, medical history and personal care habits. If pinworms are suspected, your doctor may suggest doing a test for pinworms. You may also need a physical exam, including a digital rectal exam.
