For men suffering from erectile dysfunction, they may find it too embarrassing to discuss with anyone, even their doctor or partner. Fortunately, there are lots of treatment options currently available that have been proven both safe and effective. You have probably seen many radio, television or magazine advertisements promoting the effects of drugs such as Levitra, Cialis or Viagra. The question is: which one is better? Well, the results depend on numerous factors such as your age, medical condition and expectations. For example, Viagra has been available for the longest and has a proven safety record, but it only lasts approximately 3 to 4 hours. However, Levitra normally lasts longer than Viagra and has no alcohol or food restrictions, but has more reported side effects. Cialis also works quite quickly, but the drug can remain in your system for up to 36 hours. That is why it is often referred to as the “weekend pill.” If you are deciding which one to take, it is best to discuss the advantages and disadvantages of Levitra, Cialis and Viagra with your doctor.
