4.2. Posology and method of administration

Posology

Erectile Dysfunction
Tadalafil for Use as Needed
The recommended dose is 10mg taken prior to anticipated sexual activity. In those patients in whom tadalafil 10mg does not produce an adequate effect, the maximum dose is 20mg and the maximum dosing frequency is once per day. It may be taken from 30 minutes to 36 hours prior to sexual activity. Tadalafil 10 mg and 20 mg is intended for use prior to anticipated sexual activity and it is not recommended for continuous daily use.

Tadalafil for Once Daily Use
In patients who anticipate a frequent use of Tadalafil (i.e. at least twice weekly) a once daily regimen with the lowest doses of Tadalafil might be considered suitable, based on patient choice and the physician's judgement. In these patients the recommended starting dose is 2.5mg once a day, taken at approximately the same time every day, without regard to timing of sexual activity. The dose may be increased to 5 mg once a day, based on individual efficacy and tolerability. The appropriateness of continued use of the daily regimen should be reassessed periodically.

Benign Prostatic Hyperplasia
The recommended dose is 5 mg, taken at approximately the same time every day. When therapy for BPH is initiated with Tadalafil and finasteride, the recommended dose of Tadalafil is 5mg, taken at approximately the same time every day for up to 26 weeks.

Erectile Dysfunction and Benign Prostatic Hyperplasia
The recommended dose is 5 mg, taken at approximately the same time every day, without regard to timing of sexual activity.

Elderly men
Dose adjustments are not required in elderly patients.

Men with hepatic impairment
Tadalafil for Use as Needed
The recommended dose is 10mg taken prior to anticipated sexual activity. There is limited clinical data on the safety of Tadalafil in patients with severe hepatic impairment (Child-Pugh Class C); if prescribed, a careful individual benefit/risk evaluation should be undertaken by the prescribing physician. There are no available data about the administration of doses higher than 10mg of tadalafil to patients with hepatic impairment.

Tadalafil for Once Daily Use
Once-a-day dosing has not been extensively evaluated in patients with hepatic impairment; therefore, if prescribed, a careful individual benefit/risk evaluation should be undertaken by the prescribing physician (see section 4.4 and 5.2 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Men with diabetes
Dose adjustments are not required in diabetic patients.

Paediatric population
Tadalafil should not be used in individuals below 18 years of age.

Patients taking CYP3A4 Inhibitors
Tadalafil for Use as Needed
For patients taking concomitant potent inhibitors of CYP3A4, such as ketoconazole or ritonavir, the maximum recommended dose of Tadalafil is 10mg, not to exceed once every 72 hours (see section 4.4 and 4.5 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Tadalafil for Once Daily Use
For patients taking concomitant potent inhibitors of CYP3A4, such as ketoconazole or ritonavir, the maximum recommended dose of Tadalafil is 2.5mg (see section 4.4 and 4.5 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information.

In clinical studies, tadalafil was shown to augment the hypotensive effects of nitrates. This is thought to result from the combined effects of nitrates and tadalafil on the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway. Therefore, administration of Tadalafil to patients who are using any form of organic nitrate is contraindicated (see section 4.5 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Tadalafil must not be used in men with cardiac disease for whom sexual activity is inadvisable. Physicians should consider the potential cardiac risk of sexual activity in patients with pre-existing cardiovascular disease.

The following groups of patients with cardiovascular disease were not included in clinical trials and the use of tadalafil is therefore contraindicated:

• patients with myocardial infarction within the last 90 days,

• patients with unstable angina or angina occurring during sexual intercourse,

• patients with New York Heart Association Class 2 or greater heart failure in the last 6 months,

• patients with uncontrolled arrhythmias, hypotension (< 90/50 mmHg) or uncontrolled hypertension,

• patients with a stroke within the last 6 months.

Tadalafil is contraindicated in patients who have loss of vision in one eye because of non-arteritic anterior ischaemic optic neuropathy (NAION), regardless of whether this episode was in connection or not with previous phosphodiesterase type 5 (PDE5) inhibitor exposure (see section 4.4 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

The co-administration of PDE5 inhibitors, including tadalafil, with guanylate cyclase stimulators, such as riociguat, is contraindicated as it may potentially lead to symptomatic hypotension (see Section 4.5 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
