Welcome to Healthcare MagicLisinopril
is for blood pressure and is not an antibiotic. For sinus it is better you consult an ENT Doctor to examine you first because you could be having pharyngitis
which may require nasal decongestant drops which are available over the counter and also antubiotic like Levofloxacin
which is very good for these infections. You can do Steam inhalation for good relief for time being.
