Altering a Prescription
Sometimes, people try to write in additional refills on their paper prescriptions in an attempt to illegally obtain more medication than their healthcare provider intended. This is frequently easily noticed by pharmacists, who are trained to look for such problems with prescriptions, especially those for controlled substances
For instance, a prescription for morphine
with several (or even just one) refill would be a "red flag" for any pharmacist, since morphine is a Schedule II medication and cannot be refilled. It is never a good idea to alter a prescription in an attempt to receive more refills than intended.
Checking on Controlled Substance Refills
If you are unsure if any particular prescription has any usable refills, simply ask your pharmacist. He or she will be able to quickly tell you if the prescription can be refilled, how many refills (if any) are left, and when the prescription expires. If you have no refills left, your pharmacist may be able to contact your healthcare provider for refills for Schedule III, IV, and V controlled substances.
