Clinical research has described PDE5 inhibitors like sildenafil (Viagra) and tadalafil (Cialis) as "revolutionary" for the treatment of ED. Why? These medications have a 60-70% success rate, they work fast, and they have an established safety profile.
If you've already tried one PDE5i without success, studies suggest that you should try a different PDE5i. Nearly 90% of men who've tried all the ED drugs at different times report improvements in their erections.
When taking ED medication, it's important to follow dispensing directions if you want the drugs to work as designed on ED symptoms. Studies have shown that in most cases where men weren't satisfied with sildenafil (Viagra), they were taking their medication incorrectly.
