There are only three FDA approved drugs available for treating erectile dysfunction, Viagra Cialis, or Levitra. All three are designed to get the blood flowing into the penis so that once a man gets sexually stimulated he can obtain and keep an erection. They all work in the same manner to produce an erection but what does vary is the amount of time that they work for and how quickly they work. To many people this is an important factor to be considered.
Comparing Levitra to Viagra, both begin working in about a half an hour but Levitra lasts for about five hours and Viagra lasts for about four hours. Cialis takes effect in as little as fifteen minutes and lasts for up to 36 hours. Because the three drugs are basically one in the same if you try one and it doesn’t work for you for some reason, it is unlikely that any of them will be effective.
If you suffer from prostate problems or from blood pressure issues and are on alpha blockers than it is unlikely that a doctor would recommend Cialis or Levitra online pharmacy because it could cause your blood pressure to drop seriously low. If you are on any forms of nitrates then you will likely not be a candidate for any of the erectile dysfunction medications.
The same considerations will be taken for all three medications if you have had a stroke, an irregular heartbeat or a heart attack. The side effects of all three erectile dysfunction medications are the same. Some of the side effects are a feeling of warmth or flushing, headache, stomach upset, and changes in vision. Often cialis no prescription canada also causes back pain as one of the side effects as well.
While these three medications sound a lot alike there are some significant differences too. Levitra is said to be more potent than Viagra, Cialis is not any less effective if it is taken with a greasy meal such as fast food but the other two are. Basically what it boils down to is lifestyle; there is just enough variation in each of the three medications that choosing which one will be best for you can be decided by evaluating your lifestyle. Only you know when you will need an erection and by doing a bit of research or speaking with your doctor about this you will be able to come up with a choice hat you are comfortable with
