TRICARE prescription drug costs will go up in January for the families of active duty service members, as well as retired members and their families, as Military Times reported.

Public Health Service Cmdr. Teisha Robertson, a Defense Health Agency pharmacist, said the increases were part of the fiscal year 2018 defense authorization bill.

“The changes are part of a larger effort to help fund improvements in military readiness and modernize the TRICARE health care benefit,” Robertson said, according to Federal News Network.

Most prescription co-pays will go up between $1 and $8.
