2 DOSAGE AND ADMINISTRATION

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 CIALIS without sexual activity. Others were reported to have occurred hours to days after the use of CIALIS and sexual activity. It is not possible to determine whether these events are related directly to CIALIS, 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 dermatitisNervous — migraine, seizure and seizure recurrence, transient global amnesiaOphthalmologic — visual field defect, retinal vein occlusion, retinal artery occlusionNon-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 phosphodiesterase type 5 (PDE5) inhibitors, including CIALIS. 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. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors, to the patient's underlying vascular risk factors or anatomical defects, to a combination of these factors, or to other factors [see Warnings and Precautions (5.4) and Patient Counseling Information (17.6)].Otologic — Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including CIALIS. In some of the cases, medical conditions and other factors were reported that may have also played a role in the otologic adverse events.

• Mechanism of action: Inhibits phosphodiesterase type 5 (PDE5) in smooth muscle.
• PDE5 breaks down cyclic guanosine monophosphate (cGMP).
• Sexual stimulation releases nitric oxide (NO), which increases cGMP.
• cGMP causes smooth muscle relaxation in the corpus cavernosum of the penis.
• This relaxation allows increased blood flow and an erection.
• By inhibiting PDE5, tadalafil increases cGMP levels, enhancing the erectile response.
• In BPH/urinary tract, relaxation of prostate and bladder smooth muscle improves symptoms.
• In PAH, vasodilation occurs in the pulmonary vascular bed.
• It has minimal effect on PDE6 (retina) compared to sildenafil, possibly fewer visual effects.
• It has weak inhibition of PDE11 (function unknown); clinical significance unclear.
• The effect is dependent on sexual stimulation and intact neural pathways.

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 CIALIS, 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) and Patient Counseling Information (17.7)].Urogenital — priapism [see Warnings and Precautions (5.3)]. 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 6550 men during clinical trials worldwide.

Otologic — Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including CIALIS.

What should I do if I miss a dose of tadalafil?

It is not possible to determine whether these reported events are related directly to the use of CIALIS, 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) and Patient Counseling Information (17.7)]. Urogenital — priapism [see Warnings and Precautions (5.3)]. 7 DRUG INTERACTIONS 7.1 Potential for Pharmacodynamic Interactions with CIALISNitrates — Administration of CIALIS to patients who are using any form of organic nitrate, is contraindicated. In a patient who has taken CIALIS, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse 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 [see Contraindications (4.1), Dosage and Administration (2.4) and Clinical Pharmacology (12.2)].Alpha Blockers — Caution is advised when PDE5 inhibitors are coadministered cialis buy cheap with alpha blockers. For CIALIS for use as needed, over 1300 and 1000 subjects were treated for at least 6 months and 1 year, respectively. In eight primary placebo-controlled Phase 3 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 order cialis online without a prescription 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 events were reported (see Table 1) for CIALIS for use as needed: In three placebo-controlled Phase 3 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 events were reported (see Table 2) in clinical trials of 12 weeks duration: The following adverse events were reported (see Table 3) over 24 weeks treatment duration in one placebo-controlled Phase 3 clinical study: Back pain or myalgia was reported at incidence rates described in Tables 1 and 2.

In studies of CIALIS for once daily use, events of back pain and myalgia were generally mild or moderate with a discontinuation rate of 0.3%. Across all studies with any CIALIS dose, reports of changes in color vision were rare (<0.1% of patients). The following section identifies additional, less frequent events (<2%) reported in controlled clinical trials of CIALIS for once daily use or use as needed. 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 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 Nervous — dizziness, hypesthesia, insomnia, paresthesia, somnolence, vertigo 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 The following adverse reactions have been identified during post approval use of CIALIS.

Clinical pharmacology studies have been conducted with coadministration of tadalafil with doxazosin or tamsulosin [see Warnings and Precautions (5.6), Dosage and Administration (2.4) and Clinical Pharmacology (12.2)].Antihypertensives — PDE5 inhibitors, including tadalafil, are mild systemic vasodilators. Small reductions in blood pressure occurred following coadministration of tadalafil with these agents compared with placebo. [See Warnings and Precautions (5.6) and Clinical Pharmacology (12.2)].Alcohol — Both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. 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. Tadalafil did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations.
