Cialis is a phosphodiesterase‑5 (PDE5) inhibitor that contains the active ingredient tadalafil. It’s prescribed for erectile dysfunction (ED) and is known for its long‑lasting effect, often up to 36hours.
Quick Take
- Cialis offers the longest window of effectiveness among oral ED pills.
- Viagra works fastest but wears off within 4‑6hours.
- Levitra’s onset is similar to Viagra but may cause fewer visual side effects.
- Stendra acts within 15minutes and is the newest option on the market.
- Cost, daily‑dose options, and food interactions are the biggest decision factors.
What are PDE5 inhibitors?
All four drugs mentioned here belong to the PDE5 inhibitor family. They work by blocking the enzyme phosphodiesterase‑5, which relaxes smooth muscle in the penis and allows blood to fill the erectile tissue when sexual stimulation occurs. Because they share the same mechanism, they also share common side effects such as headache, flushing, and nasal congestion.
Cialis (Tadalafil) - The Long‑Lasting Star
Generic Tadalafil is the off‑brand version of Cialis, offering the same 20mg or 10mg dosing at a lower price. The brand‑name pill comes in 2.5mg, 5mg, 10mg, and 20mg strengths.
- Onset: 30‑60minutes (can be faster on an empty stomach).
- Duration: Up to 36hours - the “weekend pill”.
- Food effect: None - can be taken with meals.
- Daily option: Yes, 2.5mg or 5mg taken every day for spontaneous activity.
- Common side effects: Muscle aches, mild headache, back pain (usually subside within 24hours).
- Cost (US 2025): Brand Cialis ≈$85 for 10 tablets; generic ≈$30 for 10 tablets.
Viagra (Sildenafil) - The Original Fast‑Acting Pill
Viagra contains sildenafil citrate and was the first oral ED medication approved in 1998.
- Onset: 30‑45minutes.
- Duration: 4‑6hours.
- Food effect: High‑fat meals can delay onset by up to 2hours.
- Daily option: No, only as‑needed doses (25mg, 50mg, 100mg).
- Common side effects: Visual disturbances (blue‑tinted vision), flushing, nasal congestion.
- Cost (US 2025): Brand ≈$70 for 10 tablets; generic ≈$20 for 10 tablets.
Levitra (Vardenafil) - The Middle‑Ground Choice
Levitra is a vardenafil‑based tablet that sits between Viagra and Stendra in terms of onset and duration.
- Onset: 25‑60minutes.
- Duration: 4‑5hours.
- Food effect: Slight delay with very fatty meals.
- Daily option: No, as‑needed (5mg, 10mg, 20mg).
- Common side effects: Headache, flushing, dizziness - fewer visual issues than Viagra.
- Cost (US 2025): Generic vardenafil ≈$25 for 10 tablets.
Stendra (Avanafil) - The Quickest Newcomer
Stendra uses avanafil, a newer PDE5 inhibitor that hits the bloodstream fast.
- Onset: 15‑30minutes - the fastest among approved pills.
- Duration: 6‑12hours.
- Food effect: Minimal, can be taken with meals.
- Daily option: No, as‑needed (50mg, 100mg, 200mg).
- Common side effects: Headache, nasal congestion, mild back pain.
- Cost (US 2025): Brand ≈$95 for 10 tablets (generic not yet widely available).
Key Decision Criteria
When you line up these four drugs, the choice usually boils down to three practical questions:
- How quickly do you need the effect? If spontaneity matters, Stendra or the low‑dose daily Cialis may win.
- How long do you want the window? For weekend plans or multiple encounters, Cialis’s 36‑hour window is unrivaled.
- What’s your budget and tolerance for side effects? Generic sildenafil and vardenafil are the most affordable, while Cialis Daily reduces “on‑demand” anxiety for regular users.
Other considerations include: existing heart conditions, use of nitrates, and whether you often eat high‑fat meals before intimacy.
Side‑Effect Snapshot
| Drug | Headache | Flushing | Vision changes | Muscle aches | Food interaction |
|---|---|---|---|---|---|
| Cialis (Tadalafil) | Medium | Low | None | High (24‑48h) | None |
| Viagra (Sildenafil) | Medium | Medium | Low‑Medium (blue‑tint) | Low | High‑fat meals delay |
| Levitra (Vardenafil) | Low‑Medium | Low‑Medium | Rare | Low | Slight delay with fatty meals |
| Stendra (Avanafil) | Low | Low | None | Low | Minimal |
Best‑Fit Scenarios
- Weekend getaway or spontaneous plans: Cialis shines because you can take one pill on Friday night and still be ready Saturday.
- Quick, single‑event needs (e.g., dinner date): Stendra’s 15‑minute onset makes it the most reliable for tight timelines.
- Budget‑conscious user who doesn’t mind timing: Generic sildenafil or vardenafil deliver solid results at the lowest cost.
- Someone who wants daily confidence without planning each time: Cialis Daily (2.5mg or 5mg) provides steady “always‑on” readiness.
- People who experience visual disturbances with Viagra: Levitra or Cialis avoid that particular side effect.
How to Choose the Right Pill for You
1. **Assess your schedule.** If you need flexibility over several hours, pick Cialis. If you need a rapid response, go with Stendra.
2. **Check health conditions.** All PDE5 inhibitors interact with nitrates; if you’re on nitroglycerin, none are safe.
3. **Consider cost.** Generic versions of sildenafil and vardenafil are typically under $25 for a month’s supply, while brand‑name Cialis and Stendra sit higher.
4. **Trial period.** Many pharmacies offer a starter pack; try one dose of each (under doctor guidance) to see which feels best.
Final Thoughts
There’s no one‑size‑fits‑all answer. The “best” ED medication aligns with how quickly you need it, how long you want it to work, your tolerance for side effects, and your wallet. By weighing those four factors, you can move from guesswork to a clear, personalized plan.
Frequently Asked Questions
Can I take Cialis and Viagra together?
No. Both are PDE5 inhibitors, and stacking them can cause a dangerous drop in blood pressure. Choose one medication and follow the prescribed dose.
Is the daily low‑dose Cialis safe for long‑term use?
Clinical studies up to five years show daily 2.5mg or 5mg dosing is well‑tolerated for most men without serious cardiovascular issues.
Do food choices affect Stendra’s effectiveness?
Stendra’s absorption isn’t significantly slowed by a meal, so you can take it before or after food without losing potency.
Which ED pill has the lowest risk of causing a headache?
Avanafil (Stendra) reports the lowest incidence of headache among the four drugs, making it a good option for headache‑prone patients.
Can I buy generic tadalafil online safely?
Yes, as long as you use a licensed online pharmacy that requires a prescription and follows local regulations. Look for certifications and read customer reviews.

If you ignore the pharmacokinetics, you’re doing your health a disservice.
I think the overview is solid and gives a clear picture of each drug’s pros and cons. It’s helpful for anyone who’s just starting to compare options. The table makes the data easy to scan.
While the article dutifully lists facts, it fails to acknowledge the profound psychological impact of choosing a pill that aligns with one’s personal narrative. One might argue that the “weekend pill” moniker for Cialis romanticizes a medical device, transforming it into a symbol of liberated spontaneity. Yet, such romanticism may obscure the very real responsibility of informed consent.
From a pharmacological perspective, each agent occupies a distinct niche. Cialis excels in duration, making it suitable for unplanned encounters, while Viagra shines in cost‑effectiveness for occasional use. It’s worth noting that food can delay sildenafil’s onset, a factor often overlooked in casual discussions.
