What is the best Erectile Dysfunction (E.D.) medicine. Pros & cons of Viagra, Cialis and Levitra.

More than 20 years have passed, since Viagra came out and made a revolution in men’s sexual life. The science didn’t stop there and developed improved preparations with the same type of action. Let’s look and compare what medicine can offer us today and what will work best for you.

Today we have 3 officially approved preparations.

Sildenafil (Viagra)

Tadafil (Cialis)

Vardenafil (Levitra)

All of them have the same mechanism of action, which relaxes your muscles, lowers blood pressure and, thus increases blood flow to your penis. However, the difference is in details, such as longevity of action, time to take an effect, contraindications and compatibility. Let’s take a closer look.


This may be important for men who want to enjoy their sex longer. If you want to have sex for the whole day, or even the whole weekend, Cialis is the best match, thanks to the action time, which lasts for nearly 36 hours. Levitra and Viagra shares second and third places with the action time of 6 and 4 hours respectively.

Time before action.

It is not that obvious here. Almost all preparations show same results. However, when it matters, every minute counts. The winner here is Levitra which starts 20-30 minutes after taking a pill. Cialis may take a bit longer, and starts 20-40 minutes after taking a pill. Old-timer Viagra gets 40-60 minutes before the action and requires a good planning compare to its siblings.


All of the preparations have a good compatibility with food, alcohol and other medications which can be used together, for example Dapoxetine. However, some food or alcohol can delay the action of Viagra by 20 minutes. Cialis has longer action time and thus it is recommended to watch alcohol intake and drink only moderate amounts, because it can further decrease blood pressure. Levitra is free of compatibility issues.

Side effects & contraindications.

Before you begin to use any of presented medicines, make sure you have no serious contraindications to take these preparations, such as:

low blood pressure

chronic heart diseases

liver problems

and any other life-threatening conditions.

We recommend to consult your doctor before taking any of these pills, as he knows better how the substance can interact with your present condition.

Regarding side effects, all of the three are well tolerated. In rare cases, you may face some of these side effects:


nasal stiffness


vision changes

It is worth noting that Levitra showed the best tolerance - side effects occur less than 2% of all cases.


We have closely reviewed these three similar preparations which have proved their effectiveness of treating erectile dysfunction. Levitra and Cialis have proved that science doesn’t stand still and almost all characteristics have been improved. We recommend to choose between these two. Take Cialis if you want longer action, and take Levitra if you want the safest and fastest option.

However, Viagra is still a good choice if you want something with long-held reputation. Also consider that our bodies can react differently on either of these preparations, so it is better not to stop on one. If it doesn’t work move to the next.
