Is there a way to get the recommended Adderall (dextroamphetamine and racemic amphetamine) prescribed by a HealthTap doctor to treat my ADHD symptoms?

No. As a controlled substance, adderall (dextroamphetamine and racemic amphetamine) needs a triplicate prescription and cannot be e-scribed. A close relationship with your doctor is important when using these meds.
Controlled Rx. Controlled substances and lifestyle enhancing drugs, including those for weight loss, are not available through this online service.
Some thoughts. Adderall is a schedule 2 controlled substance, monitored closely from the point of creation to final user. Any physician who prescribes S 2 meds without a thorough in person evaluation, testing and charted documentation can have his/her DEA license revoked and his/her medical license restricted or cancelled. Possession without a proper prescription can sent you to jail. So the answer=no.
