Warnings and precautions for Tadalafil (FDA label)

Evaluation of erectile dysfunction and BPH should include an appropriate medical assessment to identify potential underlying causes, as well as treatment options. Before prescribing tadalafil, it is important to note the following: Patients should not use tadalafil if sex is inadvisable due to cardiovascular status (5.1). Use of tadalafil with alpha-blockers, antihypertensives or substantial amounts of alcohol (≥5 units) may lead to hypotension (5.6, 5.9). Tadalafil is not recommended in combination with alpha-blockers for the treatment of BPH because efficacy of the combination has not been adequately studied and because of the risk of blood pressure lowering. Caution is advised when tadalafil is used as a treatment for ED in men taking alpha-blockers. (2.7, 5.6, 7.1, 12.2) Patients should seek emergency treatment if an erection lasts >4 hours. Use tadalafil with caution in patients predisposed to priapism (5.3).

Drug interactions for Tadalafil (FDA label)

Tadalafil can potentiate the hypotensive effects of nitrates, alpha-blockers, antihypertensives or alcohol (7.1). CYP3A4 inhibitors (e.g. ketoconazole, ritonavir) increase tadalafil exposure (2.7, 5.10, 7.2) requiring dose adjustment: Tadalafil for use as needed: no more than 10 mg every 72 hours Tadalafil for once daily use: dose not to exceed 2.5 mg CYP3A4 inducers (e.g. rifampin) decrease tadalafil exposure (7.2). 7.1 Potential for Pharmacodynamic Interactions with Tadalafil Nitrates - Administration of tadalafil to patients who are using any form of organic nitrate, is contraindicated. In clinical pharmacology studies, tadalafil was shown to potentiate the hypotensive effect of nitrates. In a patient who has taken tadalafil, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse after the last dose of tadalafil before nitrate administration is considered.
