Ever since it first hit the market back in 1998, Viagra has remained a very popular choice for men who want to enjoy longer and harder erections. The drug has been proven safe and is very effective. The only problem is that it is also very expensive to purchase. If you want to enjoy the benefits of Viagra without the high price tag, there are other effective options currently available. These include the drugs Cialis and Levitra, which work in almost the same way as Viagra. They are FDA-approved, but in addition to the lower cost, Cialis works faster and lasts longer than Viagra. The effects of Levitra also last slightly longer than Viagra, so you should talk to your doctor about which one is right for you.
