What Is Tadalafil? (Brand Names, Mechanism, and How It Works)

Tadalafil is a widely prescribed oral medication, best known by its original brand name Cialis® and also available as Adcirca® for certain conditions. Belonging to the class of phosphodiesterase type 5 inhibitors (PDE5 inhibitors), Tadalafil acts by relaxing muscles of blood vessels and increasing blood flow to particular areas of the body.

• Medical uses: Erectile Dysfunction (ED), Benign Prostatic Hyperplasia (BPH), Pulmonary Arterial Hypertension (PAH)
• FDA Approval: First approved in 2003 for ED (FDA source)
• Half-life: Up to 36 hours—longer than Viagra (Sildenafil) or Levitra (Vardenafil)

How Does Tadalafil Work in the Body?

When you take Tadalafil, it blocks the action of PDE5, an enzyme that normally constricts blood vessels. This allows your blood vessels to relax and open up, especially in the penis (for ED), the prostate/bladder (for BPH), or the lungs (for PAH). The result? Better blood flow and improved symptoms in each condition. See the detailed infographic below:

• 1️⃣ Takes effect 30-60 minutes after ingestion
• 2️⃣ Increases cGMP levels in smooth muscle
• 3️⃣ Relaxes blood vessels→ boosts blood supply
• 4️⃣ Lasts up to 36 hours (“the weekend pill”)

Tadalafil Indications: What Conditions Can It Treat?

Condition	Dose Range	Specific Notes
Erectile Dysfunction (ED)	10–20 mg as needed, or 2.5–5 mg daily	Works with sexual stimulation
Benign Prostatic Hyperplasia (BPH)	5 mg daily	Reduces urinary symptoms
Pulmonary Arterial Hypertension (PAH)	40 mg once daily	Improves exercise capacity

Tadalafil for ED: Clinical trials show success rates of 60-80% (NCBI source). Patients like its flexibility: use it “on demand” or as a low daily dose for spontaneous intimacy.

How to Use Tadalafil: Personalized Advice

• Take Tadalafil with or without food. High-fat meals might delay onset by a few minutes but do not reduce effectiveness.
• Swallow tablets whole with water.
• Avoid excessive alcohol (may worsen side effects).
• Do not take with nitrates or certain blood pressure drugs (can cause dangerous drop in blood pressure).
• Sexual stimulation still required for ED response!

Pro tip: Daily low-dose Tadalafil (2.5–5 mg) can offer continuous readiness, while higher on-demand doses (10–20 mg) are best for occasional use.

Who Should (and Shouldn’t) Use Tadalafil?

• Men over 18 years old with ED, BPH, or PAH: FDA-approved
• Not for women or children (exception: PAH in some female patients with specialist approval)
• Consult doctor if you have: Severe heart, liver, or kidney disease; recent stroke or heart attack; uncontrolled arrhythmias

Side Effects, Risks, and Warnings

Like any medication, Tadalafil has potential side effects. Most are mild and short-lived, but some require immediate medical attention.

• Common (mild): Headache, flushing, back pain, indigestion, nasal congestion, muscle aches
• Rare (serious): Sudden vision loss, hearing loss, priapism (painful, prolonged erection > 4 hours), chest pain—call emergency services
• Interactions: Nitrates, alpha blockers, some HIV medicines, antifungals, antibiotics (clarithromycin), and grapefruit juice!
