Tadalafil is an FDA-approved oral medication belonging to the PDE5 inhibitor class, most commonly recognized under the brand name Cialis. Ginagamit ito sa paggamot ng erectile dysfunction, benign prostatic hyperplasia (BPH), at pulmonary arterial hypertension sa ilalim ng medical supervision.

Oo, kahit na FDA-approved na gamot ang tadalafil, isa pa rin itong prescription medication sa Pilipinas at sa karamihan ng bansa. A licensed physician must evaluate your health history, current medications, and cardiovascular status before prescribing tadalafil, particularly because of its interaction risk with nitrate medications.

Tadalafil is taken orally as a tablet, either as a lower once-daily dose for ongoing use or a higher as-needed dose taken prior to anticipated activity. The appropriate regimen depends on the specific approved indication and is determined by your prescribing physician.

Compared to shorter-acting PDE5 inhibitors like sildenafil, tadalafil is distinguished by its significantly longer half-life of up to 36 hours, allowing for more flexible timing or once-daily dosing. It is also uniquely approved for benign prostatic hyperplasia and pulmonary arterial hypertension, in addition to erectile dysfunction.
