The brand Viagra has long been a common name when considering drugs that increase potency. However, the popularity of Viagra does not necessarily make it a better drug. For example, in Europe and in the US, doctors prescribe Viagra to only a quarter of patients, whereas Cialis is prescribed in more than half the cases.
Studies show customers prefer Cialis because of a softer action and because it works only if there is constant sexual arousal.
The use of Cialis does not require any special care in the application and has some significant advantages over Viagra including:
- can be taken with alcohol and fatty foods;
- begins to act after 15-20 minutes compared to 30-40 in the case of Viagra;
- boasts 36 hours of action, while Viagra works only for 4-5 hours;
- shorter list of contraindications;
- side effects are less frequent;
- cheaper than Viagra.
