Erectile dysfunction has traditionally been a difficult topic for both patients and doctors alike to discuss. It was difficult for doctors because effective remedies were not readily available. Viagra changed all of that. Viagra, Cialis, and Levitra are the three pills available now, FDA-approved for the treatment of erectile dysfunction. These pills all work by a similar mechanism. These tablets allow the flow of blood into the penis to increase because it prevents an enzyme within the penis from stopping that flow. As long as there’s flow of blood into the penis, these pills can increase that flow of blood. These pills have slight variations of how quickly they work and the timing of how they should be taken.
Viagra should be taken at least one hour before intercourse, and it is typically active in the system for about five or six hours. Now it may linger longer in some men, but this is the typical duration erection. It’s best to take viagra on an empty or light stomach, and it is not as effective if consumed with moderate to large amounts of alcohol. The same is true for the other brands as well.
Cialis takes about two to three hours at least to get into the system, but once it’s in the system, it can last up to 36 hours. What that means, is that the patient has up to 36 hours which to choose to engage in sexual activity. The erection will still go down after the patient reaches climax, but there is a 36-hour window of opportunity. It does not matter if it is taken with food or without food but what does matter is that a sufficient amount of time is allowed for it to work.
Levitra has a similar duration of action to Viagra that is about five to six hours. Like Viagra, it should be taken about an hour before sexual activity or more. But taking Levitra or Viagra less than an hour before the sexual activity may result in it being ineffective because not enough time was allowed for it to get into the system. Unlike Viagra, Levitra can be taken with or without food.
Which one is best? Well, they’re all very similar, and in some patients, some formulas work better than in others. In some patients, Viagra produces a stronger erection while in others is Cialis or Levitra. In some patients, Viagra causes side effects while in others it’s Cialis or Levitra.
The side effects that these medications can cause are very common, but they’re not dangerous. The typical side effects may include any one or more of the following: a headache, indigestion, facial flushing. In the case of Viagra, there’s a higher incidence seeing a blue hue around objects that you’re looking at. In the case of Cialis, there’s a greater incidence of a backache. In all cases the side effects are temporary.
The only severe risk of any of these medications is taking them in conjunction with nitroglycerin containing drugs. That may be the small nitroglycerine pill a person places under their tongue, or other prescription medications, or patches, or ointments that contain nitroglycerin. If a person is taking any drugs that contain nitroglycerin or they have the propensity to need nitroglycerin, they should not use this class of medicines to treat the erectile dysfunction.
