Tadalafil is an erectile dysfunction treatment. Commonly sold under the brand name Cialis, it helps men achieve stronger and longer-lasting erections for up to 36 hours after dosing.
Originally intended to treat heart disease, Tadalafil (generic Cialis) was found in clinical trials to be an effective treatment for erectile dysfunction. Since then, it has become one of the most trusted and widely used ED treatments in Europe, helping men regain their confidence in the bedroom and enjoy a more satisfying sex life.
Yes, Tadalafil is the generic version of the branded medication Cialis. They both contain the same active ingredient and work in the same way.
With this in mind, there are some differences. Most notably, Cialis is more expensive than its generic version, Tadalafil. While this may encourage you to choose the generic version, many people prefer Cialis as it is well-known. The manufacturer and packaging may also differ, since generics are widely produced by different manufacturers. Make sure you bear all this in mind when choosing your erectile dysfunction treatment.
Tadalafil works by widening blood vessels and relaxing muscle tissues to increase blood flow to the genitals during sexual arousal. This enhanced circulation helps men achieve and maintain stronger, longer-lasting erections.
Contrary to popular belief, Tadalafil doesn’t automatically trigger an erection. It only works in response to sexual stimulation. This means you should only feel the effects when you need to.
Clinical studies have found that up to 81% of men can experience improved erections with Tadalafil.
Here are the results of one study in particular:
Despite Sildenafil (Viagra) being the more well-known of the two erectile dysfunction medications, this study shows that patients and their partners tend to prefer Tadalafil.

This is likely due to its longer duration of action—lasting for up to 36 hours compared to just 4 for Sildenafil. This offers greater flexibility and convenient dosing, earning Tadalafil the nickname “The Weekend Pill”.
Tadalafil should begin to take effect within 30-60 minutes of taking your dose. With this in mind, it’s best to take your tablet around an hour before you plan to have sex.
Peak effectiveness is usually felt 2 hours after you take your tablet.
Tadalafil lasts a while longer than other erectile dysfunction treatments like Sildenafil. While peak effects are felt around 2 hours after dosing, it should work for up to 36 hours.
To be prescribed Tadalafil, you must be over 18 years old and suffer from erectile dysfunction.
Do not take Tadalafil if you:
There are 4 doses of Tadalafil available. Consult this table to see which one is right for you:
| Type | Dose | When to take | Consideration |
|---|---|---|---|
| Daily use | 2.5 mg | Once daily, at the same time | Gentle daily option (low dose) |
| Daily use | 5 mg | Once daily, at the same time | Most common daily starting dose |
| As needed | 10 mg | 30-60 minutes before sexual activity | Standard on-demand treatment |
| As needed | 20 mg | 30-60 minutes before sexual activity | Stronger dose if 10 mg is not enough |
IMPORTANT:
The maximum dose of Tadalafil in 24 hours is one tablet, no matter the dosage. If you take more than this, contact your doctor.
Since the effects of Tadalafil last for up to 36 hours, it is not recommended to take 10 mg or 20 mg tablets daily. For these doses, wait at least 36 hours between doses. This ensures safety while still allowing you to experience the full benefits of treatment.
If you would prefer daily dosing, Cialis Daily may be better suited for you. Available in 2.5 mg or 5 mg tablets, this lower-strength option supplies a steady stream of tadalafil in your blood, allowing for spontaneous sexual activity.
Please note:
It can take up to 3-5 days for 2.5 mg or 5 mg Tadalafil tablets to work. For on-demand treatment, consider 10 mg or 20 mg Tadalafil tablets instead.
Tadalafil can produce side effects, although not everyone will get them. The most common side effects of Tadalafil include:
For a full list of Tadalafil side effects, consult the patient information leaflet.
Yes, studies show that Tadalafil can lower blood pressure because it relaxes and widens blood vessels.
For this reason, you cannot take Tadalafil if you are currently taking nitrates or other medications that can lower blood pressure. Tell your doctor about any other medicines you take in your consultation to ensure safety.
You should avoid drinking alcohol with Tadalafil (Cialis), since both can lower blood pressure, and increase the risk of side effects like headache. It can also reduce the effectiveness of Tadalafil, since alcohol can interfere with sexual function.
While avoiding alcohol altogether when taking Tadalafil is best, you may not experience problems with one or two drinks. Speak with your doctor before drinking alcohol, and note how you feel if you do.
