Why Tadalafil Works When Sildenafil Fails | ED Guide
It is natural to think about an alternative impotence treatment when Sildenafil fails to meet your expectations. Some men even ask, “Why Tadalafil Works When Sildenafil Fails?” As most of the erectile enhancers are PDE-5 inhibitors and have a similar action mechanism, then why do men respond differently to each? If you are on a quest to find the best of Tadalafil and Sildenafil in the USA for producing satisfactory results, this blog shall help.
What is Sildenafil and Tadalafil?
Sildenafil and Tadalafil are both erectile dysfunction treatments. They are prescribed after examining overall health, severity of impotence, pre-existing health issues, medications, etc.
Being Phosphodiesterase Type 5 (PDE5) inhibitors, these medicines work upon sexual arousal when the body releases nitric oxide. These medications block PDE5 enzymes and increase cyclic GMP production for consistent blood flow to the penis. In simple words, both of these erectile enhancers make it easier for men to achieve erectile strength faster than usual. Also, they can help make intimacy last for several hours.
The practical comparison is their duration. Sildenafil works within 15 – 30 minutes and is formulated to last for around 4 – 5 hours. Tadalafil activates in 30 – 45 minutes and is specifically designed to last until 36 hours (weekend effects). Men should not confuse this activeness duration with constant erections. It only dictates their ability for better erectile function upon sexual stimulation in this timeframe.

Why may sildenafil not work for everyone?
The main reason for choosing Sildenafil is its quicker onset time. Men don’t have to wait for a longer period and are penetration-ready within a few minutes after taking the dose. It could still make for a disappointing experience due to certain reasons, as listed below.
- Incorrect dosing
- Dosage after a heavy/fatty meal resulting in delayed absorption
- Using an unsuitable dosage
- Expecting an erection to occur instantly
- Taking the dosage during sex
- Lack of sexual arousal
- Drinking alcohol together with Sildenafil
- Combining with contradictory drugs
- Certain existing health problems suppressing response
- Performance anxiety
These instances reflect why Sildenafil may not work for all men. At the same time, it highlights the need for medical evaluation and proper dosage guidance to make it work. Overdosing on Sildenafil without medical advice or switching to Tadalafil right away without reviewing dosage is not a solution here.
Why Tadalafil Works When Sildenafil Fails?
After experiencing fulfilling intercourse using Sildenafil for a while, men may shift focus to long-lasting ED medication and less frequent dosing. This calls for a reliable treatment option that meets the requirement.
Although Sildenafil and Tadalafil have similar action mechanisms, the latter is formulated to remain effective in the bloodstream until 36 hours. It frees men from dosing erectile enhancer once daily and can be taken once every alternate day while remaining sexually active for an extended period. Moreover, its low-strength dosage options make it an attractive choice. It seems a better alternative for couples preferring flexibility/unplanned intimacy. However, these specifications do not make Tadalafil a universally ‘better’ option. Some men may respond well to Sildenafil while others consider Tadalafil as a more ‘suitable’ impotence pill.
In short, the urge for long-lasting ED medicine may solve a timing or lifestyle mismatch problem. It cannot overcome any underlying cause assumed to be left unaddressed by Sildenafil.
Tadalafil vs Sildenafil: Key Differences
Check out the key differences between tadalafil vs sildenafil for making informed decisions.
| Feature | Sildenafil | Tadalafil |
| Common Brand Name | Viagra | Cialis |
| Generic Available | Yes | Yes |
| Drug class | PDE5 inhibitor | PDE5 inhibitor |
| Typical onset timings | Around 15 to 30 minutes | Around 30 to 45 minutes |
| Lasting Duration | Up to 4 or 5 hours | Approximately 36 hours i.e. weekender effects |
| Dosing preferences | Once-daily (if having sex regularly) or on-demand | On-demand or once every alternate day |
| Main benefit | Faster onset timings with short-lasting activeness window | Longer effectiveness duration offering less-frequent dosing convenience |
The success with Sildenafil or Tadalafil ultimately depends on individual preferences and accurate dosing. If you are fed up with Sildenafil and taking Tadalafil incorrectly, you’ll find it a failure too.
Could the Reason Be the Underlying Cause of ED?
At times, the reason for sildenafil not working could be beyond erectile strength. It means the underlying cause of impotence is not addressed properly. Men may encounter poor quality of erections due to hormonal problems, obesity, psychological health issues, kidney or liver disorders, prostate concerns, cardiovascular disease, performance anxiety, etc. Some might have ED as a combination of these factors too. Identifying and managing the root cause of erectile dysfunction can make it easier to achieve the desired quality of erections smoothly.
Side effects of certain medicines may also decrease libido or cause erectile difficulties. Such acquired ED may be improved by discontinuing these drugs. It might not matter whether you take Sildenafil or Tadalafil; they’ll effectively improve erections for pleasurable sexual intimacy. If nothing seems to work, focus on outlining the ‘contributor’ first.
How to know when Sildenafil is not the Right Treatment
The formula is quite easy to understand. If you’re using the suggested Sildenafil strength exactly as per dosage guidelines shared by the physician and it still produces insufficient erections, then you need a change. It could be the right time to explore Cialis vs Viagra and ask your healthcare provider for a better alternative available in the USA.
Here are a few things your physician would check before prescribing a substitute.
- Whether you used Sildenafil at the right time or not
- Did you take it with or without food?
- Have you consumed alcohol closer to the dosage timings?
- Was sexual stimulation sufficient?
If determined suitable, Tadalafil could be advised; otherwise, necessary lifestyle adjustments should be suggested first. Follow what’s been advised rather than switching to another ED medicine.
Can You Switch from Sildenafil to Tadalafil?
Yes. You may switch from Sildenafil to Tadalafil or vice versa, but only if the healthcare professional approves. They should not be used interchangeably just because they are both PDE5 inhibitors. These drugs are used for treating impotence but have different goals. Sildenafil aims to improve spontaneity better than Tadalafil does. The latter is known for providing longer playtime than Sildenafil can provide.
Can I take tadalafil if sildenafil did not work?
While safe, don’t take Tadalafil instead of Sildenafil without medical consultation. Men must receive approval to take tadalafil for erectile dysfunction and learn more about daily tadalafil dosage, safety guidelines, etc. The healthcare professional should find a reliable solution and reconsider why Sildenafil didn’t work instead of prescribing Tadalafil directly.
Conclusion
We have just shared insightful information regarding why tadalafil works when sildenafil fails. The fact is, neither can be labelled as a universal winner because ED medicines are highly personalised. Men seeking faster onset times mostly favour Sildenafil but may think about switching to Tadalafil for its unmatched playtime of 36 hours. The choice, however, depends on more factors than just onset or performance timings. If determined eligible, the physician may advise any other Sildenafil alternatives. The key to optimal results will always be dosage accuracy. Making necessary lifestyle adjustments shall enhance the effects further.
