Suppositories for Hemorrhoids

Opinion is divided over the effectiveness of suppositories in treating hemorrhoids. Although they make direct contact with the inflamed tissues, suppositories usually require several hours for the outer layer to melt off and deliver the inner core of pain relief ingredient. This melting also causes leakage that can restrict a person's activities for several hours. For some people, insertion of a suppository triggers the urge to defecate, which ends up wasting the suppository.


Most over-the-counter hemorrhoid suppositories have chemical vasoconstrictors such as phenylephrine. Vasoconstrictors shrink swollen tissues. In addition, some suppositories contain topical analgesics (pain relievers) that give temporary relief. Use of vasoconstrictors may result in a "rebound" effect, as also seen in overuse of sinus sprays, in which the mucous membranes swell up again after use is discontinued.

Because mucous membranes are so permeable, they take up active ingredients more readily than regular skin does.

Some herbal-based suppositories contain horse chestnut and butcher's broom. There is less risk of rebound swelling with these herbals than with synthetic chemicals like phenylephrine.

However, use of herbal suppositories is not without some risk. Allergic reactions listed for these herbals include: local dermatitis and even anaphylaxis in sensitive persons. Always do a patch test of herbal hemorrhoid ointments before applying to anus. Rub a small amount on your inner arm, cover with plastic wrap or a bandage, and leave for 24 hours.
