Providing Specialty Health Care Services

Rawlins County Health Center provides access to routine specialty health care services without leaving your community. Outreach physicians provide health care services on a monthly basis in several areas…

Coumadin Program

Coumadin Out-Patient Program

The use of Coumadin must be monitored closely to ensure correct dosage and to minimize the risk of bleeding due to excessive blood thinning.

Our Clinical nurse works closely with your physician to see that your needs are met. You will find it reassuring to know that a nurse will always be available to answer your questions.
