Proctofoam HC Dosing Instructions
Apply Proctofoam HC (hydrocortisone acetate 1% + pramoxine HCl 1%) to the affected anal area 3 to 4 times daily using the supplied applicator for intra-anal administration, or transfer a small amount to tissue for perianal application. 1

- Rinse cap and underlying tip to prevent foam buildup and blockage 1
Clinical Context
While rectal 5-ASA preparations are preferred over corticosteroid foams for ulcerative colitis treatment due to superior efficacy 2, corticosteroid foam preparations like Proctofoam HC offer advantages in ease of delivery, better tolerability, and improved retention compared to enemas 2. This makes the 3-4 times daily dosing practical for patients with hemorrhoids or anorectal conditions who may have difficulty retaining enemas.
