What is a Days Supply?
A “Days Supply” refers to the number of days a patient’s medication supply will last based on their prescription dosage. This information is often used by patients, healthcare providers, and pharmacists to ensure timely prescription refills, avoid lapses in medication, and monitor prescription adherence. The formula used to calculate days supply is:
Days Supply = Total Units ÷ Dosage Per Day
This simple calculation helps estimate how long your current medication will last and whether you need to order a refill soon.
