Tadalafil Pill: 36-Hour Window for ED Support
The longest-acting PDE5 inhibitor available, in a pill format that gives you flexibility around timing.
Tadalafil is a PDE5 inhibitor used for erectile dysfunction and benign prostatic hyperplasia (BPH). It’s the same active molecule as Cialis. The defining feature of tadalafil is its long half-life: a single dose can support erectile function for up to 36 hours, which is why some people use it as-needed and others use lower daily doses to maintain continuous support. Most people describe tadalafil as removing the pressure around timing that comes with shorter-acting options.

Tadalafil (PDE5 Inhibitor, long-acting): Tadalafil inhibits the enzyme PDE5, which lets smooth muscle in the penis relax and increases blood flow in response to sexual stimulation. Unlike sildenafil, tadalafil isn’t significantly affected by food, and its long half-life supports a much longer window of effect.
Best for: Adult men with erectile dysfunction who want flexibility around timing, or those interested in daily low-dose protocols. Also appropriate for men with both ED and BPH symptoms.
Not recommended for: Anyone taking nitrates or certain alpha-blockers (dangerous interaction), those with significant cardiovascular disease, severe liver or kidney disease, recent stroke, or a history of priapism.
Most common side effects are headache, flushing, nasal congestion, back pain or muscle aches (a distinctive tadalafil side effect for some patients), and mild stomach discomfort, usually improving within hours to days. Rare but more serious risks include priapism (a prolonged painful erection requiring emergency care), significant blood pressure changes, sudden vision or hearing changes, and the cardiovascular risks of combining tadalafil with nitrates.

What to know before you start.
Tadalafil (Pill) is a compounded medication prepared by a licensed pharmacy for individual patient use.
It has not been reviewed by the FDA for safety or efficacy, and is prescribed based on the clinical judgment of a qualified healthcare provider. Compounded drugs are permitted to be prescribed but are not FDA-approved for safety and efficacy.
Clinical Evidence
Tadalafil at as-needed doses (10 to 20 mg) produces clinically meaningful improvement in erectile function across the multiple international clinical trials supporting its FDA approval. Daily low-dose tadalafil (2.5 to 5 mg) also produces sustained improvement in both ED and BPH symptoms. (Source: Brock et al., Journal of Urology, 2002)
