Tadalafil 20 mg to 40 mg Given Every Second Day Is Effective in Secondary Pulmonary Hypertensio

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling:Hypotension [see Warnings and Precautions (5.1)]Visual Loss [see Warnings and Precautions (5.3) and Patient Counseling Information (17)]Hearing loss [see Warnings and Precautions (5.4)]Priapism [see Warnings and Precautions (5.6)]6.1 Clinical Trials ExperienceBecause 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 398 patients with PAH during clinical trials worldwide. In trials of tadalafil tablets, a total of 311 and 251 subjects have been treated for at least 182 days and 360 days, respectively. The overall rates of discontinuation because of an adverse event (AE) in the placebo-controlled trial were 9% for tadalafil tablets 40 mg and 15% for placebo. The rates of discontinuation because of AEs, other than those related to worsening of PAH, in patients treated with tadalafil tablets 40 mg was 4% compared to 5% in placebo-treated patients.In the placebo-controlled study, the most common AEs were generally transient and mild to moderate in intensity. Table 1 presents treatment-emergent adverse events reported by greater than or equal to 9% of patients in the tadalafil tablets 40 mg group and occurring more frequently than with placebo.6.2 Postmarketing ExperienceThe following adverse reactions have been identified during post-approval use of tadalafil. These events have been chosen for inclusion either because of their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate reliably their frequency or establish a causal relationship to drug exposure. The list does not include adverse events that are reported from clinical trials and that are listed elsewhere in this section.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 [see Contraindications (4.1)]. 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.

• Do not take Tadalafil 40mg if you are on medications containing nitrates.
• Follow the prescribed dosing schedule strictly for safety and effectiveness.
• The medication may cause a sudden drop in blood pressure in some users.
• Inform your doctor about all health conditions before starting Tadalafil.
• Do not take more than one dose per day to avoid overdose risks.
• Use this medication responsibly to manage ED effectively and safely.

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.Body as a whole — Hypersensitivity reactions including urticaria, Stevens–Johnson syndrome, and exfoliative dermatitisNervous — Migraine, seizure and seizure recurrence, and transient global amnesiaOphthalmologic — Visual field defect, retinal vein occlusion, retinal artery occlusion, and NAION [see Warnings and Precautions (5.3) and Patient Counseling Information (17)].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 tadalafil 2 5 mg and other factors were reported that may have also played a role in the otologic adverse events.

• Tadalafil 40mg can improve blood flow for longer-lasting erections.
• It typically takes about 30-60 minutes for Tadalafil 40mg to work.
• Food does not significantly affect the efficacy of Tadalafil 40mg.
• Store Tadalafil 40mg in a cool, dry place away from children.
• Tadalafil 40mg is available by prescription only in many countries.
• Do not break or crush Tadalafil 40mg tablets to avoid dose inaccuracies.

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 (5.4) and Patient Counseling Information (17)].Urogenital — Priapism [see Warnings and Precautions (5.6)].

When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. Clinical pharmacology studies have been conducted with coadministration of tadalafil with doxazosin, alfuzosin or tamsulosin [see Clinical Pharmacology (12.2)].7.3 AntihypertensivesPDE5 inhibitors, including tadalafil tablets, are mild systemic vasodilators.

• Tadalafil 40mg is sometimes used off-label for other medical conditions.
• Keep a record of your medication intake and any side effects.
• Do not share Tadalafil 40mg with others, even if they have similar symptoms.
• Tadalafil 40mg can be part of a comprehensive ED treatment plan.

Small reductions in blood pressure occurred following coadministration of tadalafil with these agents compared with placebo [see Clinical Pharmacology (12.2)].7.4 AlcoholBoth alcohol and tadalafil, 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. Substantial consumption of alcohol (e.g., 5 units or greater) in combination with tadalafil tablets can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Tadalafil (10 mg or 20 mg) did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations.
