If it's not a controlled substance you can just call, but, if it is, you'll need to go in person. If it's not, have your doctor's office call it in, or if you have a prescription that's been filled prior, just call Allen's with the prescription number and they'll refill it. And, even if you don't have the number they can call the last pharmacy you used.
Shouldn't be a problem. Ask the writer of the prescription.
