Adderall (dextroamphetamine and racemic amphetamine): Sinus Tach. without symptoms is not contraindication. Review with your prescribing doctor.

No need to suffer: While your Adderall (dextroamphetamine and racemic amphetamine) is causing your tachycardia, switching to a methylphenidate preparation like Concerta or Ritlalin LA, may give your the same benefit without the high cardiac rate.
