There are some situations that may not require an office visit for a prescription renewal. However, your particular condition and the medicine you are on may require monitoring in order to help you manage your health and obtain your optimal wellbeing. A prescription is given for certain amount of time in order for the drug to have an effect that can be measured. At the end of the period, that effect needs to be measured to determine whether the medication should continue or be changed. Without such monitoring, the medication may have mild to severe adverse effects.\n\nIt is important that you ask your provider during your visit (when you are first prescribed the medication or when the medication is renewed) whether your particular medication requires monitoring and how often you may need to come in.
