What is typically required for a pharmacist to substitute a brand-name drug for a generic?

Substituting a brand-name drug for a generic typically requires written consent from the patient. This requirement is in place to ensure that patients are fully aware of the change and agree to it, as some patients may have preferences or concerns regarding the efficacy or side effects of generics versus brand-name drugs. The process acknowledges the patient's right to be involved in their healthcare decisions.

While there may be variations in state laws and pharmacy policies, general practice typically favors obtaining patient consent to respect their autonomy and ensure informed decision-making. In many jurisdictions, pharmacists are allowed to substitute generics unless explicitly instructed otherwise by the physician or if the patient does not wish to switch. However, this does not negate the importance of having the patient's express consent documented to avoid misunderstandings or issues related to patient care and expectations.
