Stendra and daily-use Cialis are closest to being an "on demand" erectile drug; using the others requires more planning. Dr. Liou says that some men come to him after getting a prescription from their primary care doctors, claiming that the drug doesn't work. Sometimes it's because they used it incorrectly.
