hi Hema I am not sure exactly what you mean by slight block in brain. i am assuming you mean he has had a stroke. and an ischemic stroke at that. So you might want to confirm that assumption when reading the further suggestion He is on safecet, asthalin and dilo bm has ambroxol, so i am assuming he ahs an associated respiratory condition like asthma, copd etc I will therefore suggest that you can give it to him, However do talk to your neurologist, because i am unaware from your query as to the stage of block. occasionally ambroxol has a sedative action or may cause vertigo hence neurologist may avoid this medicine Best of luck Dr Saumya Mittal
