Qué dicen las etiquetas de la FDA
De la etiqueta de Tadalafilo (Cialis) · vigente desde 2026-06-03
CIALIS 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.
Clinical pharmacology studies have been conducted with coadministration of tadalafil with doxazosin, tamsulosin or alfuzosin. [see Dosage and Administration ( 2.7 ), Warnings and Precautions ( 5.6 ), and Clinical Pharmacology ( 12.2 )] .
Use of CIALIS with alpha-blockers, antihypertensives or substantial amounts of alcohol (≥5 units) may lead to hypotension ( 5.6 , 5.9 ).
Caution is advised when CIALIS is used as a treatment for ED in men taking alpha-blockers.
…Physicians should be aware that CIALIS for once daily use provides continuous plasma tadalafil levels and should consider this when evaluating the potential for interactions with medications (e.g., nitrates, alpha-blockers, anti-hypertensives and potent inhibitors of CYP3A4) and with substantial consumption of alcohol [see Drug Interactions ( 7.1 , 7.2 , 7.3 )] .
De la etiqueta de Alfuzosina (Uroxatral) · vigente desde 2024-12-05
Caution is advised for concomitant use of PDE5-inhibitors and UROXATRAL, as this combination can potentially cause symptomatic hypotension [see Drug Interactions (7.4) ].
Concomitant use of PDE5 inhibitors with alpha adrenergic antagonists, including UROXATRAL, can potentially cause symptomatic hypotension ( 5.4 , 7.4 )
PDE5 Inhibitors Caution is advised when alpha adrenergic antagonists, including UROXATRAL, are co-administered with PDE5 inhibitors.
Phosphodiesterase-5 (PDE5) Inhibitors: PDE5-inhibitors are also vasodilators.
