14 CLINICAL STUDIES

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.

• Cialis 5 mg is known for its long-lasting effects up to 36 hours.
• It may be taken with or without food, depending on preference.
• The medication helps improve erectile function over time.
• Use caution if combining with other blood pressure medicines.
• Cialis 5 mg can be effective for men with diabetes.
• Overdose symptoms may include prolonged erection or dizziness.

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 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. 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.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. Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue. 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 cialis 10mg tablet 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. These events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to the intake of PDE5 inhibitors, including CIALIS. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions (6.1) and (6.2)].5.6 Alpha blockers and AntihypertensivesPhysicians should discuss with patients the potential for CIALIS to cialis sublingual augment the blood-pressure-lowering effect of alpha blockers and antihypertensive medications [see Drug Interactions (7.1) and Clinical Pharmacology (12.2)].Caution is advised when PDE5 inhibitors are coadministered with alpha blockers. PDE5 inhibitors, including CIALIS, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated.

Shipped Within 2 - 5 Bussiness Days

In patients taking potent inhibitors of CYP3A4 and CIALIS for once daily use, the dose of CIALIS should not exceed 2.5 mg [see Dosage and Administration (2.4)].5.11 Combination With Other PDE5 Inhibitors or Erectile Dysfunction TherapiesThe safety and efficacy of combinations of CIALIS and other PDE5 inhibitors or treatments for erectile dysfunction have not been studied. Therefore, the use of such combinations is not recommended.5.12 Effects on BleedingStudies in vitro have demonstrated that tadalafil is a selective inhibitor of PDE5. When administered in combination with aspirin, tadalafil 20 mg did not prolong bleeding time, relative to aspirin alone. CIALIS has not been administered to patients with bleeding disorders or significant active peptic ulceration.

In some patients, concomitant use of these two drug classes can lower blood pressure significantly [see Clinical Pharmacology (12.2) and Drug Interactions (7.1)], which may lead to symptomatic hypotension (e.g., fainting). Consideration should be given to the following:Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor. Patients who demonstrate hemodynamic instability on alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitors.In those patients who are stable on alpha-blocker therapy, PDE5 inhibitors should be initiated at the lowest recommended dose.In those patients already taking an optimized dose of PDE5 inhibitor, alpha-blocker therapy should be initiated at the lowest dose. Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure when taking a PDE5 inhibitor.Safety of combined use of PDE5 inhibitors and alpha blockers may be affected by other variables, including intravascular volume depletion and other antihypertensive drugs.

• Do not drive if experiencing dizziness or vision changes.
• Avoid sudden standing if hypotension occurs.
• Report hearing loss or sudden decrease to doctor.
• Stop use and seek help for chest pain during sex.
• Inform surgeon if you take this before surgery.

[See Dosage and Administration (2.4) and Drug Interactions (7.1)].5.7 Renal InsufficiencyCIALIS for Use as NeededCIALIS should be limited to 5 mg not more than once in every 72 hours in patients with severe renal insufficiency or end-stage renal disease on hemodialysis.

The starting dose of CIALIS in patients with a moderate degree of renal insufficiency should be 5 mg not more than once per day, and the maximum dose should be limited to 10 mg not more than once in every 48 hours.

2.2 Use with Food

PDE5 inhibitors, including CIALIS, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. In some patients, concomitant use of these two drug classes can lower blood pressure significantly [see Clinical Pharmacology (12.2) and Drug Interactions (7.1)], which may lead to symptomatic hypotension (e.g., fainting). Consideration should be given to the following:Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor.

Taking Cialis with food

Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure when taking a PDE5 inhibitor.Safety of combined use of PDE5 inhibitors and alpha blockers may be affected by other variables, including intravascular volume depletion and other antihypertensive drugs. [See Dosage and Administration (2.4) and Drug Interactions (7.1)].5.7 Renal InsufficiencyCIALIS for Use as NeededCIALIS should be limited to 5 mg not more than once in every 72 hours in patients with severe renal insufficiency or end-stage renal disease on hemodialysis. The starting dose of CIALIS in patients with a moderate degree of renal insufficiency should be 5 mg not more than once per day, and the maximum dose should be limited to 10 mg not more than once in every 48 hours. No dose adjustment is required in patients with mild renal insufficiency [see Use in Specific Populations (8.7)].CIALIS for Once Daily UseDue to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, CIALIS for once daily use is not recommended in patients with severe renal insufficiency. No dose adjustment is required in patients with mild or moderate renal insufficiency [see Use in Specific Populations (8.7)].5.8 Hepatic ImpairmentCIALIS for Use as NeededIn patients with mild or moderate hepatic impairment, the dose of CIALIS should not exceed 10 mg.

Does dose affect the prevalence of side effects?

Because of insufficient information in patients with severe hepatic impairment, use of CIALIS in this group is not recommended [see Use In Specific Populations (8.6)].CIALIS for Once Daily UseCIALIS for once daily use has not been extensively evaluated in patients with mild or moderate hepatic insufficiency. Because of insufficient information in patients with severe hepatic impairment, use of CIALIS in this group is not recommended [see Use In Specific Populations (8.6)].5.9 AlcoholPatients should be made aware that both alcohol and CIALIS, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with CIALIS can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Dosage and Administration (2.4) and Clinical Pharmacology (12.2)].5.10 Concomitant Use of Potent Inhibitors of Cytochrome P450 3A4 (CYP3A4)CIALIS is metabolized predominantly by CYP3A4 in the liver. The dose of CIALIS should be limited to 10 mg no more than once every cialis 10mg pills 72 hours in patients taking potent inhibitors of CYP3A4 such as ritonavir, ketoconazole, and itraconazole [see Drug Interactions (7.2)]. No dose adjustment is required in patients with mild renal insufficiency [see Use in Specific Populations (8.7)].CIALIS for Once Daily UseDue to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, CIALIS for once daily use is not recommended in patients with severe renal insufficiency. No dose adjustment is required in patients with mild or moderate renal insufficiency [see Use in Specific Populations (8.7)].5.8 Hepatic ImpairmentCIALIS for Use as NeededIn patients with mild or moderate hepatic impairment, the dose of CIALIS should not exceed 10 mg.

5.12 Effects on Bleeding

How can I get the maximum effect from Cialis?

Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with CIALIS can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Dosage and Administration (2.4) and Clinical Pharmacology (12.2)].5.10 Concomitant Use of Potent Inhibitors of Cytochrome P450 3A4 (CYP3A4)CIALIS is metabolized predominantly by CYP3A4 in the liver. The dose of CIALIS should be limited to 10 mg no more than once every cialis 10mg pills 72 hours in patients taking potent inhibitors of CYP3A4 such as ritonavir, ketoconazole, and itraconazole [see Drug Interactions (7.2)]. In patients taking potent inhibitors of CYP3A4 and CIALIS for once daily use, the dose of CIALIS should not exceed 2.5 mg [see Dosage and Administration (2.4)].5.11 Combination With Other PDE5 Inhibitors or Erectile Dysfunction TherapiesThe safety and efficacy of combinations of CIALIS and other PDE5 inhibitors or treatments for erectile dysfunction have not been studied.
