Hemorrhoids are enlarged veins in the wall of the anus, usually caused by prolonged constipation or straining at the stool. The main symptom is rectal bleeding. They are commonly found in pregnant women and in people over fifty.

Local anesthetics such Nupercanal and Americaine Hemorroidal temporarily relieve the pain, burning, and itching of hemorrhoids.

Vasoconstrictors in products such as Anusol and Hemorid for Women reduce swollen hemorrhoid tissue by constricting the small arteries in the area.

Astringent wipes such as Tucks and Fleet Medicated Wipes coagulate protein in the skin cells and produce a protective coating that allows new tissue to grow.

Skin protectants protect the affected area by shielding it from irritants and preventing water loss.

Ideal preparations for external (anus and lower rectal region) hemorrhoid treatment combine a skin protectant with a vasoconstrictor to shrink the tissue, an anesthetic to reduce pain and itching, and an astringent to relieve pain and itching. Anusol and Hemorid for Women are examples of such products.

Preparations inteneded for external use only may include a topical anti-inflammatory agent such as hydrocortisone to help relieve itching and inflammation.

Suppositories are generally not recommended in treating anorectal problems because it is difficult to direct the medicine to the affected area.
