Tadalafil vs. Vardenafil: Differences, Instructions, Precautions and Side Effects

Levitra treats impotence only, while Cialis is also effective in treatment of benign prostatic hyperplasia (BPH).

Mechanism of Action and Effect Comparison

The mechanism of action is the same for these two medicines: both are PDE-5 (phosphodiesterase type 5) inhibitors. As the release of PDE-5 is blocked, the production of nitric oxide (NO), which is responsible for relaxing penile muscles and easing the blood flow throughout the corpora cavernosa, increases.

Although the mechanism is the same, there are some differences. For instance, Levitra is quicker to produce the effect than Cialis: the former starts working about 20 minutes after administration, while it may take about an hour for the latter to start working. However, Cialis is renowned for its long-lasting effect: once you have taken it, you are free to enjoy life for at least 12 hours and, at most, for 36 hours (the effect of Levitra continues for about 5 hours or so). This ‘weekend pill’ frees you from having to adjust time and rush for the right moment.

Tadalafil tablets are almond-shaped, covered in a yellow coating, and there is a “C” (stands for Cialis) and tablet dose printed on each one. There are four tablet sizes, each type bearing a specific dose of Tadalafil: 2.5 mg, 5 mg, 10 mg, 20 mg.

Vardenafil tablets are round-shaped and coated in an orange film. There are 5 mg, 10 mg and 20 mg variations. Each tablet has the dose printed on one side (5, 10, 20) and the Bayer cross on the other.

Note: Neither Cialis nor Levitra can boost your sexuality. In order for you to see the effect, there must be a natural source of excitement. It is then that the effect becomes observable.

Dosage and Administration Comparison

For Cialis, an average prescribed dose is 5 mg. Based on response, severity of dysfunction and adverse reactions, if any, it can be either increased up to 10 mg or reduced to 2.5 mg.

Levitra users are mostly advised to start with 10 mg each day. In its turn, based on your condition and reactions, it can be either reduced to 5 mg or increased up to 20 mg. Take a pill (either Cialis or Levitra) an hour before presumable sexual activity.

Both Cialis and Levitra are generally not really affected by food, however, your meal should not be too rich in fats. Particularly, doctors recommend their patients to avoid combining these drugs with fatty foods, because they may slow down the absorption of the drug.

Interactions, Precautions and Side Effects

In any case, you must be very careful and dose it properly, because consequences may range from a bit nasty to fatal. Stay away from these pharmaceuticals if you have a history of cardiovascular disorders.

  • Hypotensive drugs;
  • Drugs used to treat cardiac disorders and containing nitrates (nitroglycerin);
  • HIV/AIDS drugs.

In some cases, interactions dull the effectiveness of both drugs, in others, they may increase it beyond admissible levels. For example, such co-administration can cause priapism – a long-lasting erection, which requires emergency assistance.
