Tadalafil: Concurrent use of tadalafil and alpha-blockers may lead to symptomatic hypotension in some patients. The manufacturer of tadalafil states that patients should be stabilized on alpha blocker therapy prior to starting tadalafil at the lowest recommended dose. If hemodynamic instability is evident on alpha-blocker therapy alone, there is an increased risk of symptomatic hypotension with concomitant tadalafil therapy. Likewise, for patients currently receiving an optimized dose of tadalafil, alpha-blocker therapy should be initiated at the lowest dose. Stepwise increases in the alpha blocker dose may be associated with further hypotension when taking tadalafil. Other variables, such as intravascular volume depletion and other antihypertensive drugs, may affect the safety of concomitant use.
