warnings and cautions
5 WARNINGS AND PRECAUTIONS Evaluation of erectile dysfunction and BPH should include an appropriate medical assessment to identify potential underlying causes, as well as treatment options. Before prescribing tadalafil tablets, it is important to note the following: • Patients should not use tadalafil if sex is inadvisable due to cardiovascular status ( 5.1 ). • Use of tadalafil with alpha-blockers, antihypertensives or substantial amounts of alcohol (greater than or equal to 5 units) may lead to hypotension ( 5.6 , 5.9 ). • Tadalafil is not recommended in combination with alpha-blockers for the treatment of BPH because efficacy of the combination has not been adequately studied and because of the risk of blood pressure lowering. Caution is advised when tadalafil is used as a treatment for ED in men taking alpha-blockers. ( 2.7 , 5.6 , 7.1 , 12.2 ) • Patients should seek emergency treatment if an erection lasts greater than 4 hours. Use tadalafil with caution in patients predisposed to priapism ( 5.3 ). Patients should stop tadalafil and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of non-arteritic anterior ischemic optic neuropathy (NAION). Tadalafil should be used with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION. Patients with a “crowded” optic disc may also be at an increased risk of NAION ( 5.4 , 6.2 ). • Patients should stop tadalafil and seek prompt medical attention in the event of sudden decrease or loss of hearing ( 5.5 ). • Prior to initiating treatment with tadalafil for BPH, consideration should be given to other urological conditions that may cause similar symptoms ( 5.14 ). 5.1 Cardiovascular Physicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. Therefore, treatments for erectile dysfunction, including tadalafil, should not be used in men for whom sexual activity is inadvisable as a result of their underlying cardiovascular status. Patients who experience symptoms upon initiation of sexual activity should be advised to refrain from further sexual activity and seek immediate medical attention. Physicians should discuss with patients the appropriate action in the event that they experience anginal chest pain requiring nitroglycerin following inta...

adverse reactions
6 ADVERSE REACTIONS Most common adverse reactions (greater than or equal to 2%) include headache, dyspepsia, back pain, myalgia, nasal congestion, flushing, and pain in limb ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Ajanta Pharma USA Inc. at 1-855-664-7744 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 over 9000 men during clinical trials worldwide. In trials of tadalafil tablets for once daily use, a total of 1434, 905, and 115 were treated for at least 6 months, 1 year, and 2 years, respectively. For tadalafil tablets for use as needed, over 1300 and 1000 subjects were treated for at least 6 months and 1 year, respectively. Tadalafil tablets for Use as Needed forED In eight primary placebo-controlled clinical studies of 12 weeks duration, mean age was 59 years (range 22 to 88) and the discontinuation rate due to adverse events in patients treated with tadalafil 10 or 20 mg was 3.1%, compared to 1.4% in placebo treated patients. When taken as recommended in the placebo-controlled clinical trials, the following adverse reactions were reported ( see Table 1) for tadalafil tablets for use as needed: Table 1: Treatment-Emergent Adverse Reactions Reported by greater than or equal to 2% of Patients Treated with Tadalafil tablets (10 mg or 20 mg) and More Frequent on Drug than Placebo in the Eight Primary Placebo-Controlled Clinical Studies (Including a Study in Patients with Diabetes) for Tadalafil tablets for Use as Needed for ED a The term flushing includes: facial flushing and flushing Adverse Reaction Placebo (N=476) Tadalafil 5 mg (N=151) Tadalafil 10 mg (N=394) Tadalafil 20 mg (N=635) Headache 5% 11% 11% 15% Dyspepsia 1% 4% 8% 10% Back pain 3% 3% 5% 6% Myalgia 1% 1% 4% 3% Nasal congestion 1% 2% 3% 3% Flushing a 1% 2% 3% 3% Pain in limb 1% 1% 3% 3% Tadalafil tabletsfor Once Daily Use for ED In three placebo-controlled clinical trials of 12 or 24 weeks duration, mean age was 58 years (range 21 to 82) and the discontinuation rate due to adverse events in patients treated with tadalafil was 4.1%, compared to 2.8% in placebo...
