When working with Tadalafil, a long‑acting phosphodiesterase‑5 (PDE5) inhibitor prescribed for erectile dysfunction. Also known as Cialis, it helps men achieve and keep an erection by relaxing blood vessels in the penis. Tadalafil belongs to the PDE5 inhibitors, a drug class that includes sildenafil and vardenafil and works by blocking the enzyme that restricts blood flow. The primary condition it treats is erectile dysfunction, a condition where a man cannot develop or sustain an erection sufficient for sexual activity. Because it stays active for up to 36 hours, users often call it the “weekend pill.”
Tadalafil is a prescription‑only medication, so a doctor must evaluate your health before you start. The typical starting dose for daily use is 2.5 mg, while the as‑needed dose is 10 mg taken at least 30 minutes before intimacy. Higher doses (up to 20 mg) are reserved for those who need stronger effect, but they also raise the chance of side effects like headache, back pain, or flushing. The drug’s effectiveness hinges on timing and food—fatty meals can delay onset, though the long half‑life usually smooths out the delay. Interactions matter, especially with nitrates (used for chest pain) and some alpha‑blockers; mixing them can cause a dangerous drop in blood pressure.
Beyond erectile dysfunction, tadalafil is FDA‑approved for benign prostatic hyperplasia (BPH), relieving urinary symptoms by relaxing prostate smooth muscle. This dual‑use makes it attractive for men who experience both issues. However, it’s not suitable for everyone: men with severe heart disease, uncontrolled hypertension, or a history of stroke should avoid it unless a specialist says otherwise. Kidney or liver impairment may require dose adjustments, and alcohol can amplify side effects. Always review the full list of contraindications with your pharmacist.
