Tadalafil (Cialis)
- Long-acting
- Daily or as-needed
- Also treats BPH
Tadalafil (Cialis) is a long-acting PDE5 inhibitor with a 17.5-hour half-life. Available as as-needed (10–20 mg before sex) or daily low-dose (2.5–5 mg). The duration window enables spontaneity that the shorter-acting sildenafil cannot match, and the daily dose is also FDA-approved for BPH symptoms.
Typically used for:
Treating erectile dysfunction on demand or as a daily low-dose option.

Benefits
What Tadalafil (Cialis) can do for you.
Up to 36-hour window
Long half-life means the medication remains effective across a multi-day window — fewer planning constraints than sildenafil.
Daily-dose option
Daily 2.5–5 mg eliminates timing concerns and is often the right call for men with situational ED.
BPH bonus
At the daily dose, tadalafil also improves urinary symptoms of benign prostatic hyperplasia (BPH).
Tadalafil is a phosphodiesterase-5 (PDE5) inhibitor — the same class as sildenafil — with a substantially longer half-life.2 Marketed as Cialis, it enables both as-needed and daily-dosing protocols, and is one of the most-prescribed medications for erectile dysfunction in current US practice.1
How it works
Mechanism mirrors sildenafil: inhibiting PDE5 allows cGMP to accumulate during sexual stimulation, relaxing corpus cavernosum smooth muscle and improving blood flow. The clinically meaningful difference is duration — tadalafil's ~17.5-hour half-life means a single 10–20 mg dose can support sexual activity for up to ~36 hours.24
Daily vs. as-needed
Two protocols are FDA-approved: episodic (10–20 mg as needed, ≥30 minutes before activity) and daily (2.5–5 mg taken consistently).34 Daily dosing eliminates the need to plan around a dose and produces continuous PDE5 inhibition. Many men prefer it once they try it — particularly those who experience situational ED, who want spontaneity, or who also have BPH-related lower urinary tract symptoms.
Who it is for
Appropriate first-line therapy for ED, especially in men who value duration over speed of onset, who experience situational rather than constant ED, or who also have BPH. Same general indications and cautions as sildenafil.
Cautions
- Absolutely contraindicated with nitrates — same as all PDE5 inhibitors.
- Less food-sensitive than sildenafil but still affected by alcohol and high-fat meals.
- Side effects: headache, back/muscle pain (more characteristic of tadalafil than sildenafil), flushing, nasal congestion. Usually mild.
- Discuss with your physician re: unstable CV disease, recent stroke/MI, severe hepatic/renal impairment.
How it works
From consult to follow-up.
Initial consultation
A board-certified physician reviews your symptoms, history, and goals. At many participating clinics the first visit is complimentary.
Baseline labs
Bloodwork tailored to the protocol. Results come back in days, not weeks. We don't prescribe before we have your numbers.
Personalized protocol
Your physician calibrates your dose based on your labs and your goals — not a template. Adjustments happen as your data evolves.
Ongoing follow-up
Recheck visits at six and twelve weeks, then quarterly. Real follow-up, structured into the plan.
- Duration
- Oral medication; as-needed or daily protocol
- Results timeline
- 30-minute onset; up to ~36-hour effect window per dose
Designed around your schedule
Consults are short
Initial visits are typically 45–60 minutes. Many participating clinics waive the fee for new patients.
Telehealth follow-ups
Where state regulations allow, follow-up visits are conducted via telehealth — no extra drive time.
Medication shipped
Prescriptions ship directly from a 503B-licensed pharmacy to your door. No standing in line.
Quarterly check-ins
Real follow-up at six and twelve weeks, then quarterly. Not constant visits, not zero visits.

Daily low-dose tadalafil has been a game-changer. No planning, no timing around meals. Wish I'd known about this protocol sooner.
