The only anti erectile dysfunction drugs in the market are Viagra, Cialis, and Levitra. The US FDA has accepted these medicines several years ago as solutions for erectile dysfunction. These drugs are primarily marketed on the web. There are many pharmacies on the web that carry Viagra, Cialis, and Levitra exclusively.

If one of the drugs will not function on you, do not expect that the others will. That’s because Viagra, Cialis, and Levitra share the same active substances. They could have small variance on the length and duration of effectiveness, but essentially the pharmacological features and active ingredients of these medications are the same.

That is why you need to visit a physician if you are suffering from erectile dysfunction. It is always not recommended to self-medicate especially if you are not sure what causes your medical condition. You need to understand also that these medicines may counter with other drugs so you have to know which drugs are contraindicated against Viagra, Cialis, and Levitra. These three medicines can also cause negative effects just like other prescription drugs on the market.

Throbbing headaches are the common side effects you can experience if you take these pills. Upset stomach and diarrhea are also minor side effects of these medicines. Because these drugs provide blood to your penis, you may feel a tingling sensation and periods of flushing or redness. If you experience these side effects, you should go back to your doctor because you may have to reset your dosage.

Severe side effects of Viagra, Levitra and Cialis include painful erections, fainting, and loss of color vision. You must consult your physician if ever you experience these side effects. These medicines might not be suitable for you.

However, severe side effects from these medications are not common. These side effects were experienced only by small number of patients.
