Controlled Substance Refills
Altering a PrescriptionSometimes, 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.
