Switching From an Alpha Blocker to CIALIS (tadalafil) for BPH

Patients on alpha blocker therapy for BPH should stop the alpha blocker at least one day before starting CIALIS for once-daily use for the treatment of BPH.

The efficacy of the coadministration of an alpha blocker and Cialis® (tadalafil) for the treatment of benign prostatic hyperplasia (BPH) has not been adequately studied. (Cialis Package Insert, 2017)

As the potential vasodilatory effects of combined use could result in lowered blood pressure, the combination of tadalafil and alpha blockers is not recommended for the treatment of BPH. (Cialis Package Insert, 2017)

Patients on alpha blocker therapy for BPH should discontinue their alpha blocker at least 1 day prior to starting tadalafil for once-daily use for the treatment of BPH. (Cialis Package Insert, 2017)

Examples of alpha blockers are

  • Flomax® (tamsulosin HCl)

  • Cardura® (doxazosin mesylate)

  • Hytrin® (terazosin HCl)

  • Minipress (prazosin HCl)

  • Jalyn (dutasteride and tamsulosin HCl)

  • Uroxatral® (alfuzosin HCl), and

  • Rapaflo® (silodosin) (Cialis Patient Information, 2017).
