For intranasal use only.

Initial dosage: A dose of 70 mg is administered as two nasal sprays, one spray into each nostril. Each nasal spray device delivers two sprays. The two sprays together contain a total of 70 mg etripamil.

Do not exceed 140 mg in a 24-hour period.

2.1 Recommended

Dosage Administer as soon as possible after PSVT symptom onset. Administer CARDAMYST by the nasal route only. Each CARDAMYST device delivers two sprays for a total of 70 mg.

Recommended Dosage: Using one nasal spray device, administer one spray into each nostril for a total initial dose of 70 mg. If symptoms persist after 10 minutes, use the second nasal spray device to administer a second dose of one spray into each nostril (70 mg total). Patients and caregivers should call their healthcare provider or seek emergency medical help if symptoms do not improve within 20 minutes after a second dose. Do not exceed 140 mg in a 24-hour period. See Instructions for Use for proper nasal spray technique. If a full initial dose (i.e., 2 sprays, one in each nostril) is not administered due to device malfunction or misuse, the patient should wait at least 10 minutes before self-administering a second dose, if needed.
