I am currently taking 10 mg of adderall (dextroamphetamine and racemic amphetamine) xr I am wondering if it is safe to take with Day quil cold and flu tablets?

Medications Safe. While everybody reacts to medication differently, it is generally safe to take over the counter medications containing the decongestant "phenylephrine" at the recommended dosing with ADHD stimulant medications taken at common dose ranges, such as Adderall (dextroamphetamine and racemic amphetamine) XR 10mg once daily.
