2. (b)An inmate without funds may obtain additional OTC medications at sick call if health services staff determine that he/she has an immediate medical need which must be addressed before the inmate may again apply for OTC medications under this section.
3. (c)To prevent abuses of this section (e.g., inmate shows a pattern of depleting his or her commissary funds before requesting OTC medications), the Warden may impose restrictions on the provisions of this section.
