Final answer:
CII and CV prescriptions in Washington state do not have a specific expiration date, but individual pharmacies may have their own policies. Controlled substances may have refill limitations of up to 6 months.
Step-by-step explanation:
In Washington state, CII and CV prescriptions do not have a specific expiration date according to state law. However, individual pharmacies may have their own policies regarding prescription expiration dates. It is important to check with the specific pharmacy where the prescription was filled to determine if they have any expiration policies.
It is also worth noting that controlled substance prescriptions (CII-CV) may have limitations on the number of refills allowed, typically up to 6 months. After that period, a new prescription may be required.
It is always recommended to consult with a pharmacist or healthcare provider for specific information regarding prescription expiration dates and refill policies.
