4 CONTRAINDICATIONS 4.1 PDE-5-Inhibitors and sGC-Stimulators Do not use NITROSTAT in patients who are taking PDE-5 Inhibitors, such as avanafil, sildenafil, tadalafil, vardenafil hydrochloride. Concomitant use can cause severe hypotension, syncope, or myocardial ischemia [see Drug Interactions (7.1)]. Do not use NITROSTAT in patients who are taking the soluble guanylate cyclase stimulators, such as riociguat.
