warnings and cautions
5 WARNINGS AND PRECAUTIONS Hypotension: Carefully consider whether patients with certain underlying cardiovascular disease could be adversely affected by vasodilatory effects of ADCIRCA. Not recommended in patients with pulmonary veno-occlusive disease. ( 5.1 , 5.2 ) Effects on the eye: Sudden loss of vision could be a sign of non-arteritic ischemic optic neuropathy (NAION) and may be permanent. ( 5.3 ) Hearing impairment: Cases of sudden decrease or loss of hearing have been reported with CIALIS. ( 5.4 ) Concomitant PDE5 inhibitors: Avoid use with CIALIS or other PDE5 inhibitors. ( 5.5 ) Prolonged erection: Advise patients to seek emergency treatment if an erection lasts >4 hours. ( 5.6 ) 5.1 Hypotension ADCIRCA has vasodilatory properties that may result in transient decreases in blood pressure. Prior to prescribing ADCIRCA, carefully consider whether patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects. Patients with preexisting hypotension, with autonomic dysfunction, with left ventricular outflow obstruction, may be particularly sensitive to the actions of vasodilators. 5.2 Worsening Pulmonary Vascular Occlusive Disease Pulmonary vasodilators may significantly worsen the cardiovascular status of patients with pulmonary veno-occlusive disease (PVOD). Since there are no clinical data on administration of ADCIRCA to patients with veno-occlusive disease, administration of ADCIRCA to such patients is not recommended. Should signs of pulmonary edema occur when ADCIRCA is administered, the possibility of associated PVOD should be considered. 5.3 Visual Loss When used to treat erectile dysfunction, non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported postmarketing in temporal association with the use of phosphodiesterase type 5 (PDE-5) inhibitors, including tadalafil. Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including but not necessarily limited to: low cup to disc ratio (“crowded disc”), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking. Based on published literature, the annual incidence of NAION is 2.5-11.8 cases per 100,000 in males aged ≥50 in the general population. An observational case-crossover study eva...

adverse reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: Hypotension [see Warnings and Precautions ( 5.1 )] Visual Loss [see Warnings and Precautions ( 5.3 ) and Patient Counseling Information ( 17 )] Hearing loss [see Warnings and Precautions ( 5.4 )] Priapism [see Warnings and Precautions ( 5.6 )] The most common adverse reaction is headache. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-545 5979 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Tadalafil was administered to 398 patients with PAH during clinical trials worldwide. In trials of ADCIRCA, a total of 311 and 251 subjects have been treated for at least 182 days and 360 days, respectively. The overall rates of discontinuation because of an adverse event (AE) in the placebo-controlled trial were 9% for ADCIRCA 40 mg and 15% for placebo. The rates of discontinuation because of AEs, other than those related to worsening of PAH, in patients treated with ADCIRCA 40 mg was 4% compared to 5% in placebo-treated patients. In the placebo-controlled study, the most common AEs were generally transient and mild to moderate in intensity. Table 1 presents treatment-emergent adverse events reported by ≥9% of patients in the ADCIRCA 40 mg group and occurring more frequently than with placebo.

These events have been chosen for inclusion either because of their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors. Because these reac...
