What Are the Advantages and Disadvantages of Erectile Dysfunction Medications?
What are the advantages and disadvantages of taking a once-a-day ED medication versus an "as needed" medication?
There are several advantages and disadvantages to both, and no one option will be right for all men (or all couples). Clearly, using an ED medication on an as-needed basis (only before anticipated sex) is going to be more cost-effective in most cases, particularly if you don't have sex very often.
Even if cost is not an issue, it doesn't really make sense to take a medication every single day if you have sex rarely, such as only on special occasions. All erectile dysfunction medications currently available are approved for as-needed use, which is not the case for once-a-day use, and this means that there are more options for treating ED if you desire only as-needed treatment.
For men who desire frequent sex (a few times a week or more often), a once-a-day ED medication might be a better choice. Currently, there is only one medication approved for once-daily ED treatment: Cialis®, which is also approved at a higher strength for as-needed use. A once-daily option is helpful for men who always want to be ready for sex, without having to wait for an as-needed medication to start working.
Finally, once-daily Cialis is also approved to treat an enlarged prostate. For men who have both an enlarged prostate and erectile dysfunction, this treatment might be ideal. However, it has yet to be seen how insurance companies will view such treatment (traditionally, most insurance companies don't cover ED medications).
