Oak Hill pharmacist Stu Walker says it's impacted his customers, "Patients have been scurrying all over town to get their prescriptions filled. Frustrating for them, frustrating for the doctors and frustrating for us as well because you hate to say no I can't fill your prescription or I can't even get it."
The drug enforcement agency has quotas to quell the black market for pills like Adderall and Ritalin, but with a growing demand for legitimate use, those quotas are creating some shortages.
Dr. Steven Pliszka of the UT Health Science center says so far, his patients haven't been impacted.
He said, "All of our patients are reporting they're able to get their medication. It surprised me because at least here in san antonio, we don't seem to be experiencing that, at least not with our clinics here."
Doctors write more than 50 million prescriptions for ADHD drugs with total sales at more than seven billion dollars.
ADHD advocacy groups say the shortages must be addressed by the government.
Pliszka said, "So hopefully, it's something that will get itself resolved here fairly quickly."
Pharmacists say the best thing you can do if you or your child is on one of these drugs is to contact your pharmacy and let them know what kind of supplies you'll be needing so they can plan ahead.
