Final answer:
Prescriptions for non-controlled substances are generally valid for one year after the issue date, but this may vary depending on the country or state.
Step-by-step explanation:
For non-controlled substances, prescriptions are generally valid for one year after the issue date. This means that the prescription can be filled at a pharmacy within one year from the date it was written by a healthcare provider. After one year, the prescription is no longer considered valid.
It's important to note that this may vary depending on the country or state. Some states in the United States have specific regulations that require prescriptions to be filled within a shorter timeframe, such as 6 months. Additionally, certain medications may have specific expiration dates indicated on the prescription label.
Overall, it's always best to check with your healthcare provider or pharmacist for specific information regarding the validity of a prescription.
