Contraindications

4 CONTRAINDICATIONS Use of phosphodiesterase type 5 (PDE-5) Inhibitors, such as avanafil, sildenafil, tadalafil, or vardenafil, or soluble guanylate cyclase (sGC) stimulator (riociguat). ( 4.1 , 7.1 ) Severe anemia. ( 4.2 ) Increased intracranial pressure. ( 4.3 ) Hypersensitivity to Nitroglycerin Lingual Spray or to other nitrates or nitrites or any excipient. ( 4.4 ) 4.1 P DE-5 - I nhibitors and sGC- S timulators Do not use Nitroglycerin Lingual Spray in patients who are taking PDE-5-Inhibitors, such as avanafil, sildenafil, tadalafil, or vardenafil. Concomitant use can cause severe hypotension, syncope, or myocardial ischemia [see Drug Interactions (7.1) ]. Do not use Nitroglycerin Lingual Spray in patients who are taking soluble guanylate cyclase (sGC) stimulators, such as riociguat. Concomitant use can cause hypotension. 4.2 Severe Anemia Nitroglycerin Lingual Spray is contraindicated in patients with severe anemia (large doses of nitroglycerin may cause oxidation of hemoglobin to methemoglobin and could exacerbate anemia). 4.3 Increased I ntracranial P ressure Nitroglycerin Lingual Spray may precipitate or aggravate increased intracranial pressure and thus should not be used in patients with possible increased intracranial pressure (e. g. cerebral hemorrhage or traumatic brain injury). 4.4 Hypersensitivity Nitroglycerin Lingual Spray is contraindicated in patients who are allergic to nitroglycerin, other nitrates or nitrites or any excipient. 4. 5 Circulatory F ailure and S hock Nitroglycerin Lingual Spray is contraindicated in patients with acute circulatory failure or shock.

Pregnancy & Breastfeeding

8.1 Pregnancy Risk summary Limited published data on the use of nitroglycerin are insufficient to determine a drug associated risk of major birth defects or miscarriage. In animal reproduction studies, there were no adverse developmental effects when nitroglycerin was administered intravenously to rabbits or intraperitoneally to rats during organogenesis at doses greater than 64-times the human dose [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 – 4% and 15 – 20%, respectively. Data Animal Data No embryotoxic or postnatal development effects were observed with transdermal application in pregnant rabbits and rats at doses up to 240 mg/kg/day for 13 days, at intraperitoneal doses in pregnant rats up to 20 mg/kg/day for 11 days, and at intravenous doses in pregnant rabbits up to 4 mg/kg/day for 13 days.
