Not necessarily. Pharmacies have arbitrary power.

My doctor gives me a three month prescription for a scheduled substance and I've had a couple pharmacies reject it because it's "sketchy". Of course, they never offer to call my doctor to confirm anything. They just smirk and cross their arms.

Well what do you really expect from pharmacies, when failure to exercise such discretion can get them sued for millions or even billions of dollars? Blame lawmakers and lawyers.

Even OTC amphetamines have purchased limits, some imposed by law depending on the state.

I guess you're suggesting that they rejected my prescription because of supply issues, they openly said it was because it was suspicious (3-mo in cash), and also Vyvanse hasn't had shortages like generic amphetamine in 2022-2023.

Also, I think you mean OTC amphetamine alternatives since amphetamine is sched I.

These pharmacists have very real personal liability if they end up getting fingered as being a supplier of components used to make illegal drugs. That's why they look askance at this prescription.

Not supply issues, meth manufacturing suspicion. Yeah, precursors to their manufacture.

Amphetamine (Dexedrine) is schedule II, not schedule I. Doctors cannot generally prescribe schedule I substances like LSD. Pseudoephedrine is a substituted amphetamine so referring to it as "an OTC amphetamine" is technically reasonable although potentially misleading.
