Tadalafil (Cialis)
Chewable tablets or capsules.
Unlike older ED medications that require strict timing, Tadalafil offers the freedom of a 36-hour window. Available as daily low-dose (2.5-5mg) for 24/7 readiness, or as-needed (10-20mg) for planned intimacy. Also shown to improve lower urinary tract symptoms.

Our medical team will evaluate if this medication is right for you during your consultation.
Dosage & Administration
Daily Use: 2.5mg to 5mg taken at the same time each day. Provides continuous readiness without timing around intimacy.
As-Needed: 10mg to 20mg taken 30-60 minutes before intimacy. Effects last up to 36 hours.
Dosing is carefully personalized based on your response, other medications, and health profile.
Important: Like any prescribed medication, dosing varies from person to person. Always follow the dosage prescribed by your healthcare provider. Optimize 360 personalizes every protocol based on your labs, symptoms, and goals.
Side Effects
- Headache: The most common complaint, usually mild.
- Back Pain / Muscle Aches: Unique to Tadalafil — dull ache in lower back or thighs, typically resolves in 24-48 hours.
- Nasal Congestion: Stuffy nose from blood vessel dilation.
- Flushing: Warmth or redness in face/chest.
- Indigestion: Mild stomach discomfort.
Warning: Do NOT take Tadalafil if you take nitrate medications for chest pain (Nitroglycerin). The combination can cause dangerous blood pressure drops.
What Is Tadalafil?
Tadalafil (brand name Cialis) is a PDE5 inhibitor that treats erectile dysfunction by increasing blood flow to the penis during sexual arousal. What makes tadalafil unique among ED medications is its exceptionally long half-life — approximately 17.5 hours, giving it an active window of up to 36 hours. This has earned it the nickname "the weekend pill," though at Optimize 360, we often prescribe it as a daily low-dose medication that provides continuous, around-the-clock readiness without any timing around intimacy.
Tadalafil was FDA-approved for ED in 2003 and has over two decades of safety data. It's also FDA-approved for benign prostatic hyperplasia (BPH), meaning it can simultaneously improve urinary symptoms in men with enlarged prostates — a dual benefit that sildenafil doesn't offer.
How Tadalafil Works
During sexual arousal, your body releases nitric oxide (NO) in the penile tissue. NO activates an enzyme called guanylate cyclase, which produces cyclic GMP (cGMP) — the molecule that relaxes smooth muscle in the blood vessels of the penis, allowing blood to flow in and create an erection. PDE5 is the enzyme that breaks down cGMP, ending the erection. Tadalafil inhibits PDE5, allowing cGMP to accumulate longer and blood flow to be maintained more effectively. Important: tadalafil doesn't create arousal — it enhances the physical response to arousal that's already happening.
Daily vs As-Needed Dosing
Daily Low-Dose (2.5-5mg): Taken at the same time every day regardless of sexual activity. Provides continuous readiness — no planning required, no waiting period. Particularly beneficial for men in relationships with frequent intimacy, men who experience performance anxiety around "timing" the medication, and men with concurrent BPH/urinary symptoms. This is our most commonly prescribed protocol at Optimize 360.
As-Needed (10-20mg): Taken 30-60 minutes before anticipated intimacy. Effects last up to 36 hours. Better for men with less frequent sexual activity or those who prefer not to take a daily medication. The 36-hour window means you can take it Friday evening and have coverage through Sunday — far more flexible than sildenafil's 4-6 hour window.
Tadalafil vs Sildenafil (Viagra)
Duration: Tadalafil lasts 24-36 hours; sildenafil lasts 4-6 hours. Tadalafil wins for spontaneity.
Onset: Both work within 30-60 minutes. Sildenafil may work slightly faster for some men, but tadalafil's longer window makes onset time less critical.
Food interactions: Sildenafil's absorption is significantly reduced by fatty meals. Tadalafil is unaffected by food — no dietary restrictions.
Side effects: Similar profiles. Tadalafil is more likely to cause back pain/muscle aches (temporary, typically 24-48 hours). Sildenafil is more likely to cause visual changes (blue tint).
Daily dosing: Only tadalafil is available as a daily low-dose option. Sildenafil is as-needed only.
BPH benefit: Only tadalafil is FDA-approved for urinary symptoms related to enlarged prostate.
Tadalafil and Hormone Optimization
Here's what most ED clinics miss: if your testosterone is low, PDE5 inhibitors may not work optimally. Testosterone drives nitric oxide production — the very molecule that tadalafil enhances. When we optimize testosterone alongside prescribing tadalafil, many patients find they need lower doses or can eventually reduce their reliance on the medication as natural erectile function improves. This is why Optimize 360 checks hormones first, not just writes a Cialis prescription.
Who Should NOT Take Tadalafil
Nitrate medications: If you take nitroglycerin or any nitrate for chest pain, tadalafil is absolutely contraindicated. The combination can cause a dangerous, potentially fatal drop in blood pressure.
Alpha-blockers: Caution required — both lower blood pressure. Dosing must be carefully managed.
Recent stroke or heart attack: Discuss with your provider. Sexual activity itself carries cardiovascular demands.
Severe liver or kidney disease: Dose adjustment or avoidance may be necessary.
At Optimize 360, comprehensive health history and lab work before prescribing ensures tadalafil is safe for you specifically.
Frequently Asked Questions
How long does it take for Tadalafil (Cialis) to work?
Initial effects are typically noticeable within 2-4 weeks, with full optimization developing over 2-3 months. Timeline varies by individual — your provider monitors progress and adjusts your protocol based on lab results and symptom response at your 6-8 week follow-up.
Can I combine Tadalafil (Cialis) with other treatments?
Yes — in fact, integrated protocols are often more effective than single-medication approaches. At Optimize 360, we design protocols that combine complementary treatments (hormone therapy, peptides, GLP-1 medications) for synergistic results. Your provider evaluates interactions and designs a safe, effective combination protocol.
How is Tadalafil (Cialis) at Optimize 360 different from buying elsewhere?
Three differences: 1) Medical oversight — prescribed after comprehensive lab work, not auto-generated by an algorithm. 2) Pharmaceutical-grade sourcing from licensed U.S. pharmacies. 3) Integrated protocols — Tadalafil (Cialis) is part of your complete optimization plan, not prescribed in isolation. Plus unlimited provider access, regular monitoring, and transparent pricing.
Do I need to come in person?
No. We serve patients nationwide via telehealth. Comprehensive labs at a Quest or LabCorp near you, video consultation with your provider, medications shipped to your door. In-person visits available at our Muncie, IN clinic if you prefer face-to-face care.
What happens if I experience side effects?
Contact your provider immediately via our unlimited messaging system. Most side effects are manageable through dose adjustment or timing changes. We monitor labs regularly to catch issues before they become problems. If a medication isn't right for you, we transition to an alternative — we have multiple options for every treatment category.
