How to Calculate 90-Day Supply

This article outlines how patients, caregivers, and dispensaries calculate a patient's 90-day supply.

Calculate 90-Day Supply

A patient's 90-day supply or recommendation is divided into two 45-day fill periods based upon the patient's current, active recommendation.

1. The first fill period consists of days 1-45 of the recommendation and the second fill period consists of days 46-90 of the recommendation.
   1. The first fill period begins when the patient receives a recommendation.
2. In each 45-day fill period, a patient may purchase up to a 45-day supply of medical marijuana, regardless of when purchases are made within the 45-day fill period.
   1. For example, if a patient who has not purchased any product during the fill period comes in on day 25, the patient may purchase up to a 45-day supply of medical marijuana. 
3. If the 45-day fill period has been exhausted (i.e., the patient has purchased a 45-day supply within the fill period), the patient must wait until the next 45-day fill period to purchase additional medical marijuana. 
   1. A patient is not required to purchase a full 45-day supply in a full period and may purchase less than a 45-day supply. 
   2. Conversely, if a patient does not purchase any medical marijuana within a 45-day fill period, the patient is only permitted to purchase a maximum of a 45-day supply of medical marijuana during the next fill period.
4.  You may use the "Patient Fill Period Calculator" provided by the Ohio Board of Pharmacy.
   1. This can be accessed via https://com.ohio.gov/divisions-and-programs/cannabis-control/patients-caregivers/patient-and-caregiver-registry/patient-fill-period-calculator.
   2. This information can also be accessed directly from the "Purchase Summary" section of the patient's MMR profile.
