Is it risky getting controlled substances prescribed through telehealth?

Sorry if this isn’t strictly the type of question you prefer to deal with, but I don’t know where else to ask.

I (34M, in the US) have been using a telehealth service (ADHD Online) for Ritalin for years.

I work in a high stakes job where inattention on my part can cost lives. Medications are a big part of keeping my brain on track.

But my pharmacy has been increasingly weird about letting me pick up prescriptions, and recently keep asking whether the provider is telehealth and/or based in a different city (yes and yes).

No other red flags — I’m on the same dose for years, I’ve never had an Rx for any other controlled substances, I don’t look sketchy, I’m not rude, etc.

Is there something legally risky about writing/filling/getting Schedule II drug via Telehealth? What’s the best way to continue on the same dose of the same med without getting any hassle?
