Adult dose

For oral administration. Use in adult men The recommended dose of this medicine is 10mg, taken before anticipated sexual activity, with or without food. For patients in whom tadalafil 10mg does not provide sufficient effect, 20 mg may be tried. This medicine may be taken at least 30 minutes before sexual activity. The maximum recommended dosing frequency is once daily. Long-term safety after extended daily administration has not been established, and because the effect of this medicine usually lasts for more than one day, continuous daily administration of this medicine is strongly discouraged.

Use in men with renal impairment No dose adjustment is required in patients with mild to moderate renal impairment. The maximum recommended dose in patients with severe renal impairment is 10mg. [See section 11.2) Pharmacokinetic Properties.] Use in men with hepatic impairment The recommended dose of this product is 10mg, taken before anticipated sexual activity, with or without food. Since clinical data on the safety of this product in patients with severe hepatic impairment (Child-Pugh Class C) are limited, the physician should carefully assess the individual benefit/risk when prescribing. There are no data on administration of doses higher than 10mg to patients with hepatic impairment. [See section 3.

This drug is for the treatment of erectile dysfunction. Before use, one must be accurately diagnosed by a physician to determine the cause of the erectile dysfunction. As it may impose a burden on the heart during sexual activity, patients with cardiovascular diseases must have their heart condition evaluated before taking this medication, and if any cardiac-related symptoms occur during sexual activity, they must stop immediately and consult a doctor. If an erection lasts for more than 4 hours after taking this medication or if it's accompanied by pain, one must visit a medical institution immediately, as failure to treat can result in penile tissue damage and permanent erectile dysfunction. This drug should not be taken with nitrate medications as it can cause a rapid drop in blood pressure, and patients who are taking nitrates must never use it and avoid nitrates during its use. Patients with significant cardiovascular diseases such as myocardial infarction, unstable angina, heart failure, or stroke, or who have had these conditions recently, should not take this medication. Patients with certain hereditary retinal diseases or hypersensitivity to this medication or its components should also not use it. It is not recommended to take this medication together with other erectile dysfunction treatments due to lack of safety and efficacy confirmation. Individuals with severely impaired kidney or liver function need to take special precautions, and side effects such as decreased blood pressure may occur when used with certain drugs, thus they should consult a doctor.
