Cialis

CIALIS — tadalafil tablet, film coated
Rebel Distributors Corp.

1 INDICATIONS AND USAGE

1.1 Erectile Dysfunction

CIALIS is indicated for the treatment of erectile dysfunction.

2 DOSAGE AND ADMINISTRATION

2.1 Erectile Dysfunction

CIALIS for Use as Needed

  • The recommended starting dose of CIALIS for use as needed in most patients is 10 mg, taken prior to anticipated sexual activity.
  • The dose may be increased to 20 mg or decreased to 5 mg, based on individual efficacy and tolerability. The maximum recommended dosing frequency is once per day in most patients.
  • CIALIS for use as needed was shown to improve erectile function compared to placebo up to 36 hours following dosing. Therefore, when advising patients on optimal use of CIALIS, this should be taken into consideration.

CIALIS for Once Daily Use

  • The recommended starting dose of CIALIS for once daily use is 2.5 mg, taken at approximately the same time every day, without regard to timing of sexual activity.
  • The CIALIS dose for once daily use may be increased to 5 mg, based on individual efficacy and tolerability.

2.2 Use with Food

CIALIS may be taken without regard to food.

2.3 Use in Special Populations

Renal Insufficiency

CIALIS for Use as Needed

  • Mild (creatinine clearance 51 to 80 mL/min): No dose adjustment is required.
  • Moderate (creatinine clearance 31 to 50 mL/min): A starting dose of 5 mg not more than once per day is recommended, and the maximum dose should be limited to 10 mg not more than once in every 48 hours.
  • Severe (creatinine clearance <30 mL/min and on hemodialysis): The maximum recommended dose is 5 mg not more than once in every 72 hours [see Warnings and Precautions (5.7) and Use In Specific Populations (8.7)].

CIALIS for Once Daily Use

  • Mild (creatinine clearance 51 to 80 mL/min): No dose adjustment is required.
  • Moderate (creatinine clearance 31 to 50 mL/min): No dose adjustment is required.
  • Severe (creatinine clearance <30 mL/min and on hemodialysis): CIALIS for once daily use is not recommended [see Warnings and Precautions (5.7) and Use In Specific Populations (8.7)].

Hepatic Impairment

CIALIS for Use as Needed

  • Mild or moderate (Child Pugh Class A or B): The dose of CIALIS should not exceed 10 mg once per day. The use of CIALIS once per day has not been extensively evaluated in patients with hepatic insufficiency and therefore, caution is advised.
  • Severe (Child Pugh Class C): The use of CIALIS is not recommended [see Warnings and Precautions (5.8) and Use in Specific Populations (8.6)].

CIALIS for Once Daily Use

  • Mild or moderate (Child Pugh Class A or B): CIALIS for once daily use has not been extensively evaluated in patients with hepatic insufficiency. Therefore, caution is advised if CIALIS for once daily use is prescribed to these patients.
  • Severe (Child Pugh Class C): The use of CIALIS is not recommended [see Warnings and Precautions (5.8) and Use in Specific Populations (8.6)].

Geriatrics

  • No dose adjustment is required in patients >65 years of age.

2.4 Concomitant Medications

Nitrates

  • Concomitant use of nitrates in any form is contraindicated [see Contraindications (4.1)].

Alpha Blockers

  • When CIALIS is coadministered with an alpha blocker, patients should be stable on alpha-blocker therapy prior to initiating treatment with CIALIS, and CIALIS should be initiated at the lowest recommended dose [see Warnings and Precautions (5.6), Drug Interactions (7.1) and Clinical Pharmacology (12.2)].

CYP3A4 Inhibitors

CIALIS for Use as Needed — For patients taking concomitant potent inhibitors of CYP3A4, such as ketoconazole or ritonavir, the maximum recommended dose of CIALIS is 10 mg, not to exceed once every 72 hours [see Warnings and Precautions (5.10) and Drug Interactions (7.2)].

CIALIS for Once Daily Use — For patients taking concomitant potent inhibitors of CYP3A4, such as ketoconazole or ritonavir, the dose should not exceed 2.5 mg [see Warnings and Precautions (5.10) and Drug Interactions (7.2)].

3 DOSAGE FORMS AND STRENGTHS

Four strengths of film-coated, almond-shaped tablets (not scored) are available in different sizes and different shades of yellow:

2.5-mg tablets debossed with “C 2 1/2”
5-mg tablets debossed with “C 5”
10-mg tablets debossed with “C 10”
20-mg tablets debossed with “C 20”

4 CONTRAINDICATIONS

4.1 Nitrates

Administration of CIALIS to patients who are using any form of organic nitrate, either regularly and/or intermittently, is contraindicated. In clinical pharmacology studies, CIALIS was shown to potentiate the hypotensive effect of nitrates. This is thought to result from the combined effects of nitrates and CIALIS on the nitric oxide/cGMP pathway [see Clinical Pharmacology (12.2)].

4.2 Hypersensitivity Reactions

is contraindicated in patients with a known serious hypersensitivity to tadalafil (CIALIS or ADCIRCA). Hypersensitivity reactions have been reported, including Stevens-Johnson syndrome and exfoliative dermatitis [see Adverse Reactions (6.2)].

5 WARNINGS AND PRECAUTIONS

Evaluation of erectile dysfunction should include an appropriate medical assessment to identify potential underlying causes, as well as treatment options.

Before prescribing CIALIS, it is important to note the following:

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 CIALIS, 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 intake of CIALIS. In such a patient, who has taken CIALIS, where nitrate administration is deemed medically necessary for a life-threatening situation, at least 48 hours should have elapsed after the last dose of CIALIS before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring. Therefore, patients who experience anginal chest pain after taking CIALIS should seek immediate medical attention. [See Contraindications (4.1) and Patient Counseling Information (17.1)].

Patients with left ventricular outflow obstruction, (e.g., aortic stenosis and idiopathic hypertrophic subaortic stenosis) can be sensitive to the action of vasodilators, including PDE5 inhibitors.

The following groups of patients with cardiovascular disease were not included in clinical safety and efficacy trials for CIALIS, and therefore until further information is available, CIALIS is not recommended for the following groups of patients:

  • myocardial infarction within the last 90 days
  • unstable angina or angina occurring during sexual intercourse
  • New York Heart Association Class 2 or greater heart failure in the last 6 months
  • uncontrolled arrhythmias, hypotension (<90/50 mm Hg), or uncontrolled hypertension (>170/100 mm Hg)
  • stroke within the last 6 months.

As with other PDE5 inhibitors, tadalafil has mild systemic vasodilatory properties that may result in transient decreases in blood pressure. In a clinical pharmacology study, tadalafil 20 mg resulted in a mean maximal decrease in supine blood pressure, relative to placebo, of 1.6/0.8 mm Hg in healthy subjects [see Clinical Pharmacology (12.2)]. While this effect should not be of consequence in most patients, prior to prescribing CIALIS, physicians should carefully consider whether their patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects. Patients with severely impaired autonomic control of blood pressure may be particularly sensitive to the actions of vasodilators, including PDE5 inhibitors.
