Dosage Considerations – Should be Given as Follows:
Erectile Dysfunction (ED)
Cialis
As needed use: 10 mg orally initially before sexual activity, with or without food; may be increased to 20 mg or reduced to 5 mg on basis of efficacy and tolerability; in most patients, maximum dosing frequency is once daily
Once-daily use: 2.5 mg/day orally in single daily dose, without regard to timing of sexual activity, with or without food; may be increased to 5 mg/day on basis of efficacy and tolerability
Dosing considerations
As needed use: Decrease dose with concomitant use of potent CYP3A4 inhibitor (e.g., ritonavir, ketoconazole, itraconazole); not to exceed 10 mg/72 hours
Once-daily use: Decrease dose with concomitant use of potent CYP3A4 inhibitor (e.g., ritonavir, ketoconazole, itraconazole); not to exceed 2.5 mg/day
Benign Prostatic Hyperplasia
Treatment of signs and symptoms of benign prostatic hyperplasia (BPH); daily use also indicated for treatment of patients with both BPH and erectile dysfunction
Cialis
BPH: 5 mg orally once daily
BPH with erectile dysfunction: 5 mg orally once daily, taken at approximately same time each day without regard to timing of sexual activity
With finasteride for BPH: tadalafil 5 mg plus finasteride 5 mg orally once daily for up to 26 weeks
Pulmonary Arterial Hypertension (PAH)
Adcirca
40 mg orally once daily; dividing dose for more frequent dosing is not recommended
Patients also taking ritonavir: 20 mg orally once daily initially for 1 week or more; may be increased to 40 mg/day on basis of tolerability
Dosing considerations
If possible, avoid coadministration with CYP3A4 inhibitors; if coadministration is essential, long-term therapy is indicated, or strong CYP3A4 inhibitors are required, modify or hold dose
Patients already taking strong CYP3A4 inhibitor who require tadalafil: 20 mg orally once daily; may be increased to 40 mg/day on basis of tolerability
Patients already taking tadalafil who require strong CYP3A4 inhibitor: Avoid using tadalafil while starting strong CYP3A4 inhibitor; stop tadalafil 24 hours or more before starting strong CYP3A4 inhibitor; after 1 week, resume tadalafil at 20 mg orally once daily; may be increased to 40 mg/day on basis of tolerability
Geriatric Dosing
Erectile Dysfunction (ED)
Cialis: No dosage adjustment is warranted solely on basis of age; however, greater sensitivity to medications in some older individuals should be considered
Pulmonary Arterial Hypertension (PAH)
Adcirca: Lower dose or reduced dosing frequency may be required in elderly because of decreased renal or hepatic clearance

Mild (CrCl 51 mL/min or more): No dosage adjustment needed
Moderate (CrCl 30-50 mL/min): Not to exceed 5 mg orally once daily initially; maximum dosage, 10 mg orally every 48 hours
