Uniroid HC preparations contain 2 active ingredients: hydrocortisone and cinchocaine, which is used to treat  haemorrhoids. Hydrocortisone works to reduce inflammation, itching and torn skin around the anus. Cinchocaine is an anaesthetic used to relieve pain.

This treatment is available in two forms; ointment or suppositories. The ointment is generally prescribed for external piles (however, it can be applied to internal piles with the included applicator). The suppositories are prescribed to treat internal piles.
