The Arizona Department of Corrections says it will immediately triple the number of free sanitary napkins it provides each month to female inmates.
Tuesday's move comes as a proposal in the Legislature that mandates an unlimited supply of tampons, napkins or pads was stalled after a committee chairman said the prison system was addressing the issue.
Female inmates will now be issued 36 sanitary napkins a month for free and can get more if needed. Tampons are only provided free when medically needed, but inmates can buy them at the commissary.
Democratic Rep. Athena Salman was pushing the proposal to provide an unlimited number of free napkins, tampons or other feminine hygiene products.
Before Tuesday's policy change, the agency provided inmates with 12 free pads each month and inmates could get more if needed. They could not keep more than 24 at any one time.
There are about 3,900 female inmates at the state's women's prison west of Phoenix.
