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)].2.4 Concomitant MedicationsAlpha BlockersWhen 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)].
17.7 Sudden Hearing Loss
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 Reactionsis contraindicated in patients with a known serious hypersensitivity to tadalafil (CIALIS or ADCIRCA). This is thought to result from the combined effects of nitrates and CIALIS on the nitric oxide/cGMP pathway [see Clinical Pharmacology (12.2)]. is contraindicated in patients with a known serious hypersensitivity to tadalafil (CIALIS or ADCIRCA). 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 CardiovascularPhysicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. [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 daysunstable angina or angina occurring during sexual intercourseNew York Heart Association Class 2 or greater heart failure in the last 6 monthsuncontrolled 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.
How can I get the maximum effect from Cialis?
Patients with severely impaired autonomic control of blood pressure may be particularly sensitive to the actions of vasodilators, including PDE5 inhibitors.5.2 Potential for Drug Interactions When Taking CIALIS for Once Daily UsePhysicians should be aware that CIALIS for once daily use provides continuous plasma tadalafil levels and should consider this when evaluating the potential for interactions with medications (e.g., nitrates, alpha-blockers, anti-hypertensives and potent inhibitors of CYP3A4) and with substantial consumption of alcohol [see Drug Interactions (7.1), (7.2), (7.3)].5.3 Prolonged ErectionThere have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds. Patients who have an erection lasting greater than 4 hours, whether painful or not, should seek emergency medical attention.CIALIS should be used with caution in patients who have conditions that might predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia), or in patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease).5.4 EyePhysicians should advise patients to stop use of all PDE5 inhibitors, including CIALIS, and seek medical attention in the event of a sudden loss of vision in one or both eyes. Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision, including permanent loss of vision that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or other factors. Physicians should also discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye, including whether such individuals could be adversely affected by use of vasodilators such as PDE5 inhibitors [see Adverse Reactions (6.2)].Patients with known hereditary degenerative retinal disorders, including retinitis pigmentosa, were not included in the clinical trials, and use in these patients is not recommended.5.5 Sudden Hearing LossPhysicians should advise patients to stop taking PDE5 inhibitors, including CIALIS, and seek prompt medical attention in the event of sudden decrease or loss of hearing.

[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 daysunstable angina or angina occurring during sexual intercourseNew York Heart Association Class 2 or greater heart failure in the last 6 monthsuncontrolled 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.

| Bioavailability | Approximately 36% | |
| Metabolism | Primarily via CYP3A4 enzyme | |
| Half-life | About 17.5 hours | Longer than many ED medications |
| Excretion | Mainly via feces (~61%) and urine (~36%) |
Patients with severely impaired autonomic control of blood pressure may be particularly sensitive to the actions of vasodilators, including PDE5 inhibitors.5.2 Potential for Drug Interactions When Taking CIALIS for Once Daily UsePhysicians should be aware that CIALIS for once daily use provides continuous plasma tadalafil levels and should consider this when evaluating the potential for interactions with medications (e.g., nitrates, alpha-blockers, anti-hypertensives and potent inhibitors of CYP3A4) and with substantial consumption of alcohol [see Drug Interactions (7.1), (7.2), (7.3)].5.3 Prolonged ErectionThere have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds.
