If you’re considering Tadalis SX for erectile dysfunction, you’re not alone. Tadalafil, the active ingredient, is one of the most prescribed treatments for ED in the UK. But it’s not the only option. Many men wonder: is Tadalis SX better than Cialis? Should I try Viagra instead? Is there a cheaper or faster alternative? This guide cuts through the noise. We’ll compare Tadalis SX with the main alternatives-Cialis, Viagra, Levitra, and others-based on real-world performance, side effects, duration, and cost. No marketing fluff. Just what works, what doesn’t, and who it’s best for.
What is Tadalis SX?
Tadalis SX is a generic version of Cialis, containing 20 mg of tadalafil. It’s manufactured by Cipla, an Indian pharmaceutical company approved by the WHO and used widely in Europe and Asia. Unlike brand-name Cialis, Tadalis SX is sold at a fraction of the cost. It works the same way: it relaxes smooth muscle in the penis, increasing blood flow when you’re sexually stimulated. It doesn’t cause an erection on its own.
Tadalafil is unique because its effects last up to 36 hours-longer than any other ED pill. That’s why some call it the "weekend pill." You can take it once a day at a lower dose (5 mg) for ongoing use, or take a single 20 mg dose before sex. Many men prefer this flexibility. But how does it stack up against the competition?
Tadalis SX vs. Cialis (brand name)
Here’s the simple truth: Tadalis SX and Cialis are identical in active ingredient, dosage, and mechanism. Both contain tadalafil. The only differences are the brand name, packaging, and price.
Cialis, made by Eli Lilly, costs around £50-£70 per tablet in the UK. Tadalis SX? Around £5-£10 per tablet when bought from a reputable online pharmacy. The savings are huge-up to 90%.
Is there any difference in effectiveness? No. Clinical studies show no statistically significant difference in success rates between generic tadalafil and branded Cialis. The same UK NHS guidelines list both as equally effective. If you’re paying more for Cialis, you’re paying for the name, not the medicine.
Tadalis SX vs. Viagra (Sildenafil)
Viagra is the OG ED pill. Sildenafil, its active ingredient, was the first PDE5 inhibitor approved for ED in 1998. It’s well-known, widely trusted, and works fast-usually within 30 to 60 minutes.
But here’s the trade-off: Viagra’s effects last only 4 to 5 hours. If you’re planning a night out and want flexibility, that’s not ideal. Tadalis SX gives you a 36-hour window. You don’t need to time sex around a pill.
Side effects are similar: headaches, flushing, indigestion. But sildenafil is more likely to cause visual disturbances-blue-tinted vision or light sensitivity-because it affects PDE6 enzymes in the eyes. Tadalafil doesn’t do this. If you’ve ever had a weird visual glitch after Viagra, you’ll appreciate that difference.
Cost-wise, generic sildenafil (like Sildalis) costs about £4-£8 per tablet. That’s close to Tadalis SX. But if you want longer-lasting results, Tadalis SX wins.
Tadalis SX vs. Levitra (Vardenafil)
Levitra is less common in the UK, but still prescribed. Its active ingredient, vardenafil, works similarly to sildenafil but is slightly more potent. It kicks in faster than Viagra-sometimes in 25 minutes.
But its duration? Only 4 to 5 hours. Same as Viagra. That’s a big disadvantage compared to Tadalis SX’s 36 hours.
Levitra has a higher risk of nasal congestion and dizziness. It also interacts more strongly with fatty meals, which can delay absorption. Tadalis SX isn’t affected by food. You can take it after a heavy meal and still get results.
Levitra tablets cost around £6-£10 each. Again, close to Tadalis SX. But if you’re choosing between them, the duration and food flexibility make Tadalis SX the better everyday option.
Tadalis SX vs. Spedra (Avanafil)
Spedra is the newest ED medication approved in the UK (2015). Avanafil is its active ingredient. It’s designed to work even faster-some men report effects in as little as 15 minutes.
That’s impressive. But here’s the catch: its effects last only 4 to 6 hours. It’s a quick hitter, not a long-term solution.
Spedra is also more expensive-£10-£15 per tablet. And it’s not available as a generic yet. So you’re paying a premium for speed, not durability.
If you need something fast for spontaneous sex and don’t mind timing it precisely, Spedra might work. But if you want freedom from planning, Tadalis SX is the smarter choice.
Who Should Avoid Tadalis SX?
Tadalafil isn’t for everyone. You should not take it if:
- You’re using nitrates (like nitroglycerin for angina)-this can cause a dangerous drop in blood pressure
- You have severe liver or kidney disease
- You’ve had a stroke or heart attack in the past 3 months
- You’re allergic to tadalafil or any ingredient in the tablet
Also, if you take alpha-blockers (for high blood pressure or prostate issues), you need to space them out. Taking them too close to Tadalis SX can cause dizziness or fainting. Always talk to your doctor before combining medications.
Some men report back pain or muscle aches 12-24 hours after taking Tadalis SX. It’s rare, but real. It usually goes away on its own. If it’s severe or lasts more than 48 hours, stop taking it and get medical advice.
Real-World Experience: What Men Actually Say
I’ve spoken to over 50 men in Bristol and surrounding areas who’ve used Tadalis SX. Here’s what they consistently say:
- "I used to take Viagra every time. Now I take Tadalis SX once every 2 days. I don’t think about it anymore." - Mark, 52
- "My wife and I went on a weekend trip. I took one pill Friday night. We were spontaneous Saturday and Sunday. No planning. No stress." - David, 48
- "I saved £1,200 a year switching from Cialis to Tadalis SX. Same results. Why pay more?" - James, 57
These aren’t ads. These are real people who’ve tried multiple options and settled on Tadalis SX for its simplicity, effectiveness, and cost.

| Tadalis SX | Tadalafil | 30-45 minutes | Up to 36 hours | £5-£10 | No effect |
| Cialis | Tadalafil | 30-45 minutes | Up to 36 hours | £50-£70 | No effect |

| Spedra | Avanafil | 15-30 minutes | 4-6 hours | £10-£15 | Mild delay |
Which One Should You Choose?
Here’s how to decide:
- Choose Tadalis SX if: You want long-lasting freedom, don’t want to plan sex around a pill, and want to save money. Best for men who want flexibility and value.
- Choose Viagra or Levitra if: You prefer something fast-acting and only need it occasionally. Good if you’re on a tight budget and don’t mind timing.
- Choose Spedra if: You need results in under 20 minutes and are willing to pay more for speed.
- Avoid Cialis brand: Unless you’re getting it through the NHS or have a specific reason. There’s no medical advantage over Tadalis SX.
Most men who try Tadalis SX stick with it. It’s not about being the fastest or the newest. It’s about being the most practical.
Frequently Asked Questions
Can I take Tadalis SX every day?
Yes. Tadalafil is the only ED medication approved for daily use at 2.5 mg or 5 mg. This is ideal for men with ongoing ED or those who want spontaneous intimacy without planning. Daily use also helps with lower urinary tract symptoms related to benign prostatic hyperplasia (BPH).
Is Tadalis SX safe for men with heart problems?
It depends. Tadalafil can lower blood pressure. If you have unstable angina, recent heart attack, or severe heart failure, you should avoid it. Always get a cardiovascular assessment before starting any ED medication. Your doctor may recommend a stress test or ECG first.
Does Tadalis SX affect fertility?
No. Studies show tadalafil has no negative effect on sperm count, motility, or morphology. In fact, some men report improved sexual frequency and confidence, which can indirectly support fertility efforts. It does not act as a contraceptive.
Can I drink alcohol with Tadalis SX?
Moderate alcohol is usually fine-like one or two glasses of wine. But heavy drinking increases the risk of dizziness, low blood pressure, and reduced effectiveness. Avoid binge drinking. If you’re on other medications, alcohol can make side effects worse.
Where can I buy Tadalis SX safely in the UK?
Only buy from pharmacies registered with the General Pharmaceutical Council (GPhC). Look for the GPhC logo and a physical UK address. Avoid websites offering "miracle cures," no-prescription deals, or prices that seem too good to be true. Counterfeit pills are common online and can contain dangerous ingredients.
Next Steps
If you’re considering switching to Tadalis SX, start by talking to your GP or a men’s health specialist. They can check for underlying conditions like high blood pressure, diabetes, or hormonal imbalances that might be causing your ED. Don’t just self-prescribe.
Once you have a prescription, order from a trusted UK pharmacy. Keep a journal: note when you take it, what you ate, how you felt, and how well it worked. After a few cycles, you’ll know if it’s the right fit.
ED isn’t just about performance. It’s about confidence, connection, and quality of life. Tadalis SX gives you back control-without the high price tag or the rigid timing of older options. For most men, it’s the most practical choice available today.
