Indications & Usage
1 INDICATIONS AND USAGE Tadalafil is a phosphodiesterase 5 (PDE5) inhibitor indicated for the treatment of: erectile dysfunction (ED) ( 1.1 ) the signs and symptoms of benign prostatic hyperplasia (BPH) ( 1.2 ) ED and the signs and symptoms of BPH (ED/BPH) ( 1.3 ) If tadalafil is used with finasteride to initiate BPH treatment, such use is recommended for up to 26 weeks ( 1.4 ).
1.1 Erectile Dysfunction Tadalafil tablets, USP are indicated for the treatment of erectile dysfunction (ED).
1.2 Benign Prostatic Hyperplasia Tadalafil tablets, USP are indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH).

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 for ED 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 tablets for 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-treated patients.
The following adverse reactions were reported ( see Table 2) in clinical trials of 12 weeks duration: Table 2: Treatment-Emergent Adverse Reactions Reported by greater than or equal to 2% of Patients Treated with Tadalafil for Once Daily Use (2.5 mg or 5 mg) and More Frequent on Drug than Placebo in the Three Primary Placebo-Controlled Phase 3 Studies of 12 weeks Treatment Duration (Including a Study in Patients with Diabetes) for Tadalafil tablets for Once Daily Use for ED Adverse Reaction Placebo (N=248) Tadalafil 2.5 mg (N=196) Tadalafil 5 mg (N=304) Headache 5% 3% 6% Dyspepsia 2% 4% 5% Nasopharyngitis 4% 4% 3% Back pain 1% 3% 3% Upper respiratory tract infection 1% 3% 3% Flushing 1% 1% 3% Myalgia 1% 2% 2% Cough 0% 4% 2% Diarrhea 0% 1% 2% Nasal congestion 0% 2% 2% Pain in extremity 0% 1% 2% Urinary tract infection 0% 2% 0% Gastroesophageal reflux disease 0% 2% 1% Abdominal pain 0% 2% 1% The following adverse reactions were reported ( see Table 3) over 24 weeks treatment duration in one placebo-controlled clinical study: Table 3: Treatment-Emergent Adverse Reactions Reported by greater than or equal to 2% of Patients Treated with Tadalafil tablets for Once Daily Use (2.5 mg or 5 mg) and More Frequent on Drug than Placebo in One Placebo-Controlled Clinical Study of 24 Weeks Treatment Duration for Tadalafil tablets for Once Daily Use for ED Adverse Reaction Placebo (N=94) Tadalafil 2.5 mg (N=96) Tadalafil 5 mg (N=97) Nasopharyngitis 5% 6% 6% Gastroenteritis 2% 3% 5% Back pain 3% 5% 2% Upper respiratory tract infection 0% 3% 4% Dyspepsia 1% 4% 1% Gastroesophageal reflux disease 0% 3% 2% Myalgia 2% 4% 1% Hypertension 0% 1% 3% Nasal congestion 0% 0% 4% Tadalafil tablets for Once Daily Use for BPH and for ED and BPH In three placebo-controlled clinical trials of 12 weeks duration, two in patients with BPH and one in patients with ED and BPH, the mean age was 63 years (range 44 to 93) and the discontinuation rate due to adverse events in patients treated with tadalafil was 3.6% compared to 1.6% in placebo-treated patients.
Adverse reactions leading to discontinuation reported by at least 2 patients treated with tadalafil included headache, upper abdominal pain, and myalgia.
The following adverse reactions were reported ( see Table 4).
Table 4: Treatment-Emergent Adverse Reactions Reported by greater than or equal to 1% of Patients Treated with Tadalafil tablets for Once Daily Use (5 mg) and More Frequent on Drug than Placebo in Three Placebo-Controlled Clinical Studies of 12 Weeks Treatment Duration, including Two Studies for Tadalafil tablets for Once Daily Use for BPH and One Study for ED and BPH Adverse Reaction Placebo (N=576) Tadalafil 5 mg (N=581) Headache 2.3% 4.1% Dyspepsia 0.2% 2.4% Back pain 1.4% 2.4% Nasopharyngitis 1.6% 2.1% Diarrhea 1.0% 1.4% Pain in extremity 0.0% 1.4% Myalgia 0.3% 1.2% Dizziness 0.5% 1.0% Additional, less frequent adverse reactions (less than 1%) reported in the controlled clinical trials of Tadalafil for BPH or ED and BPH included: gastroesophageal reflux disease, upper abdominal pain, nausea, vomiting, arthralgia, and muscle spasm.
Back pain or myalgia was reported at incidence rates described in Tables 1 through 4.
In tadalafil clinical pharmacology trials, back pain or myalgia generally occurred 12 to 24 hours after dosing and typically resolved within 48 hours.
The back pain/myalgia associated with tadalafil treatment was characterized by diffuse bilateral lower lumbar, gluteal, thigh, or thoracolumbar muscular discomfort and was exacerbated by recumbency.
In general, pain was reported as mild or moderate in severity and resolved without medical treatment, but severe back pain was reported with a low frequency (less than 5% of all reports).
When medical treatment was necessary, acetaminophen or non-steroidal anti-inflammatory drugs were generally effective; however, in a small percentage of subjects who required treatment, a mild narcotic (e.g., codeine) was used.
Overall, approximately 0.5% of all subjects treated with tadalafil for on demand use discontinued treatment as a consequence of back pain/myalgia.
In the 1-year open label extension study, back pain and myalgia were reported in 5.5% and 1.3% of patients, respectively.
Diagnostic testing, including measures for inflammation, muscle injury, or renal damage revealed no evidence of medically significant underlying pathology.
Incidence rates for tadalafil for once daily use for ED, BPH and BPH/ED are described in Tables 2, 3 and 4.
In studies of tadalafil for once daily use, adverse reactions of back pain and myalgia were generally mild or moderate with a discontinuation rate of less than 1% across all indications.
Across placebo-controlled studies with tadalafil for use as needed for ED, diarrhea was reported more frequently inpatients 65 years of age and older who were treated with tadalafil (2.5% of patients) [see Use in Specific Populations ( 8.5 )] .
Across all studies with any tadalafil dose, reports of changes in color vision were rare (less than 0.1% of patients).
The following section identifies additional, less frequent events (less than 2%) reported in controlled clinical trials of tadalafil for once daily use or use as needed.
A causal relationship of these events to tadalafil is uncertain.
Excluded from this list are those events that were minor, those with no plausible relation to drug use, and reports too imprecise to be meaningful: Body as a Whole — asthenia, face edema, fatigue, pain, peripheral edema Cardiovascular — angina pectoris, chest pain, hypotension, myocardial infarction, postural hypotension, palpitations, syncope, tachycardia Digestive — abnormal liver function tests, dry mouth, dysphagia, esophagitis, gastritis, GGTP increased, loose stools, nausea, upper abdominal pain, vomiting, gastroesophageal reflux disease, hemorrhoidal hemorrhage, rectal hemorrhage Musculoskeletal — arthralgia, neck pain Nervous — dizziness, hypesthesia, insomnia, paresthesia, somnolence, vertigo Renal and Urinary — renal impairment Respiratory — dyspnea, epistaxis, pharyngitis Skin and Appendages — pruritus, rash, sweating Ophthalmologic — blurred vision, changes in color vision, conjunctivitis (including conjunctival hyperemia), eye pain, lacrimation increase, swelling of eyelids Otologic — sudden decrease or loss of hearing, tinnitus Urogenital — erection increased, spontaneous penile erection 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of tadalafil.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
These events have been chosen for inclusion either due to their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors.
Cardiovascular and Cerebrovascular — Serious cardiovascular events, including myocardial infarction, sudden cardiac death, stroke, chest pain, palpitations, and tachycardia, have been reported postmarketing in temporal association with the use of tadalafil.
Most, but not all, of these patients had preexisting cardiovascular risk factors.
Many of these events were reported to occur during or shortly after sexual activity, and a few were reported to occur shortly after the use of tadalafil without sexual activity.
Others were reported to have occurred hours to days after the use of tadalafil and sexual activity.
It is not possible to determine whether these events are related directly to tadalafil, to sexual activity, to the patient’s underlying cardiovascular disease, to a combination of these factors, or to other factors [see Warnings and Precautions ( 5.1 )] .
Body as a Whole — hypersensitivity reactions including urticaria, Stevens-Johnson syndrome, and exfoliative dermatitis Nervous — migraine, seizure and seizure recurrence, transient global amnesia Ophthalmologic — visual field defect, retinal vein occlusion, retinal artery occlusion Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely postmarketing in temporal association with the use of PDE5 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.
[see Warnings and Precautions ( 5.4 )] .
Otologic — Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including tadalafil.
In some of the cases, medical conditions and other factors were reported that may have also played a role in the otologic adverse events.
In many cases, medical follow-up information was limited.
It is not possible to determine whether these reported events are related directly to the use of tadalafil, to the patient’s underlying risk factors for hearing loss, a combination of these factors, or to other factors [see Warnings and Precautions ( 5.5 )] .
Urogenital — priapism [see Warnings and Precautions ( 5.3 )].
