Cialis, Viagra, and Levitra are all medicines used for erectile dysfunction, but they mainly differ in how long they last, how quickly they work, and how food affects them. Cialis usually lasts much longer (up to 36 hours), and Viagra and Levitra last around 4–6 hours. Cialis can be taken daily or as needed, while Viagra and Levitra are usually taken only when required.
Comparison of Cialis, Viagra and Levitra
Cialis
If you take Cialis, you will notice that it lasts much longer compared to the others up to 36 hours. This gives you more flexibility since you don’t have to plan the timing as strictly. Cialis can also be used as a low-dose daily tablet, which means you’re ready any time without waiting. It generally starts working in about 30 minutes, and food does not reduce its effect.
Viagra
When you use Viagra, it starts working in about 30 to 60 minutes. The effect usually lasts 4 to 6 hours. One thing you should keep in mind is that heavy or fatty meals may slow down its absorption, which could delay the effect. Viagra is taken as needed, not daily.
Levitra
Levitra works in a very similar way to Viagra, taking effect in 30 to 60 minutes and lasting about 4 to 5 hours. Just like Viagra, food can sometimes reduce how quickly it works, but it may have a slightly better tolerance for people with certain health conditions (like diabetes).
Summary for You
Cialis: Best if you want a longer window of up to 36 hours or prefer a daily low-dose option.
Viagra: Works reliably for 4–6 hours but may be delayed by food.
Levitra: Similar to Viagra in timing and duration, but sometimes better tolerated by men with health conditions.
Is a Cialis 20mg is equal to a Viagra tablet?
No, Cialis 20mg is not equal to Viagra 100mg because both medicines contain different active ingredients and work differently in your body, even though they are used for the same condition.
Cialis 20mg
If you take a Cialis 20mg tablet, the active ingredient is tadalafil. It usually starts working in about 30 minutes and can last up to 36 hours. This long duration gives you a much wider window of time for sexual activity without needing to plan strictly around the dose. Cialis can also be taken in lower doses daily, but 20mg is the maximum strength used when taken as needed.
Viagra 100mg
When you take Viagra 100mg, the active ingredient is sildenafil. It generally starts working in 30 to 60 minutes and lasts about 4 to 6 hours. The 100mg strength is the highest commonly prescribed dose, usually taken only when needed. Heavy or fatty meals can delay its effect, so you may notice it works more slowly if you eat before taking it.
