8.7 Renal Insufficiency
May increase to 5 mg based upon efficacy and tolerability (2.1). CIALIS may be taken without regard to food (2.2). Patients should not use CIALIS if sex is inadvisable due to cardiovascular status (5.1). Use of CIALIS 2 5 mg cialis daily with alpha blockers, antihypertensives or substantial amounts of alcohol (≥5 units) may lead to hypotension (5.6, 5.9). If taking potent inhibitors of CYP3A4, dose should be adjusted: CIALIS for use as needed: ≤10 mg every 72 hours.
When to take
For once daily use: dose not to exceed 2.5 mg (5.10). Patients should seek emergency treatment if an erection lasts >4 hours. Use CIALIS with caution in patients predisposed to priapism (5.3). Patients should stop CIALIS and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non Arteritic Ischemic Optic Neuropathy (NAION). Discuss increased risk of NAION in patients with history of NAION (5.4). Increase to 20 mg or decrease to 5 mg based upon efficacy/tolerability.

The dose may be increased to 20 mg or decreased to 5 mg, based on individual efficacy and tolerability. The maximum recommended dosing frequency is once per day in most patients.

Multiple dose pharmacokinetics
Mild (creatinine clearance 51 to 80 mL/min): No dose adjustment is required. Use of CIALIS 2 5 mg cialis daily with alpha blockers, antihypertensives or substantial amounts of alcohol (≥5 units) may lead to hypotension (5.6, 5.9).
- 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.
If taking potent inhibitors of CYP3A4, dose should be adjusted: CIALIS for use as needed: ≤10 mg every 72 hours.
