I stopper taking adderall xr 3 days ago, can i take advil, (ibuprofen) cold & sinus nightime ?

Sure you can: Yes you can take advil (ibuprofen). Be carefull with the Adderall withdrawal affects, usually presents with headaches, fatigue, and sometimes dissociation affects. Overall, there is no contraindication with these meds you have listed.

Yes: Advil (ibuprofen) nighttime contains Ibuprofen (advil (ibuprofen)) and Diphenhydramine (also known as benadryl). There are no interactions between Adderall and these drugs. The daytime version of advil (ibuprofen) cold and sinus contains pseudephedrine, which would likely add to the stimulant effect of adderall. Three days out from adderall-xr would probably be enough time elapsed to take the daytime version.
