How long is a written prescription good for?
That depends. In the United States, each state sets the parameters for prescriptions. This means that states decide how long a prescription can be refilled. For example, in Ohio a non-controlled prescription must be initially filled within 6 months or it expires. If it is filled the first time within the six months, it is then good for one year from the date written. Example: You get a prescription for fexofenadine (Allegra, generic) written on 11-13-2006. You must fill it for the first time before 5-13-2007 or it expires. Say you fill it on 1-3-2007, it is then refillable until 11-13-2007. In Ohio, controlled substances (e.g. Vicodin, etc.) are only valid for a total of 6 months, no exceptions Check with your local pharmacist or State Board of Pharmacy (or Regulatory Body) for the complete answer in your state or country.
