1 INDICATIONS AND USAGE NITROSTAT is indicated for the acute relief of an attack or acute prophylaxis of angina pectoris due to coronary artery disease. NITROSTAT is a nitrate vasodilator indicated for relief of an attack or prophylaxis of angina pectoris due to coronary artery disease. ( 1 )

2 DOSAGE AND ADMINISTRATION Administer one tablet under the tongue or in the buccal pouch at the first sign of an acute anginal attack. Allow tablet to dissolve without swallowing. One additional tablet may be administered every 5 minutes until relief is obtained. No more than three tablets are recommended within a 15-minute period. If the pain persists after a total of 3 tablets in a 15-minute period, or if the pain is different than is typically experienced, seek prompt medical attention. NITROSTAT may be used prophylactically 5 to 10 minutes prior to engaging in activities that might precipitate an acute attack. For patients with xerostomia, a small sip of water prior to placing the tablet under the tongue may help maintain mucosal hydration and aid dissolution of the tablet. Administer NITROSTAT at rest, preferably in the sitting position. • At the onset of an attack, administer one tablet under the tongue or buccal pouch. One additional tablet may be administered every 5 minutes as needed. No more than 3 total tablets are recommended within a 15 minute period. ( 2 ) • If chest pain persists after three tablets, seek prompt medical attention. ( 2 ) • May be used prophylactically 5 to 10 minutes prior to engaging in activities that might precipitate an acute attack. ( 2 )

4 CONTRAINDICATIONS • Use of phosphodiesterase type 5 (PDE-5) inhibitors, such as avanafil, sildenafil, tadalafil, or vardenafil, or soluble guanylate cyclase (sGC) stimulators. ( 4.1 , 7.1 ) • Severe anemia ( 4.2 ) • Increased intracranial pressure ( 4.3 ) • Hypersensitivity to NITROSTAT or to other nitrates or nitrites or any excipient ( 4.4 ) • Circulatory failure and shock ( 4.5 ) 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. Concomitant use can cause hypotension. 4.2 Severe Anemia NITROSTAT 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 Intracranial Pressure NITROSTAT 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 NITROSTAT is contraindicated in patients who are allergic to nitroglycerin, other nitrates or nitrites or any excipient. 4.5 Circulatory Failure and Shock NITROSTAT is contraindicated in patients with acute circulatory failure or shock.

6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail elsewhere in the label: • Hypotension [see Warnings and Precautions (5.2) ] • Headache [see Warnings and Precautions (5.4) ] • Hypersensitivity [see Contraindications (4.4) ] Vertigo, dizziness, weakness, palpitation, and other manifestations of postural hypotension may develop occasionally, particularly in erect, immobile patients. Marked sensitivity to the hypotensive effects of nitrates (manifested by nausea, vomiting, weakness, diaphoresis, pallor, and collapse) may occur at therapeutic doses. Syncope due to nitrate vasodilatation has been reported. Flushing, drug rash, and exfoliative dermatitis have been reported in patients receiving nitrate therapy. Most common adverse reactions occurring at a frequency greater than 2% are headache, dizziness and paresthesia.
