My husband has had erectile dysfunction for 8 months. he takes lodine, (etodolac) prednisone, vicodin 10/325. which one is causing the ed or is it all three?

ED: Non of the medications you listed listed can cause erectile dysfunction.

Unclear but may hold: Any medicine can cause many different side effects in a given person. Also, different persons react differently to different medicines. Therefore, he may hold vicodin one or two doses to see if it makes a different. Cannot hold Prednisone however without doctors permission. Lodine (etodolac) also can be held off and on. However, the big question is not this, it is what is the underlying illness effect?

All of the above...: Assuming that you two have a good relationship and that he's not distracted by stress eg work, family, bills, etc, his tobacco smoking doesn't help his erectile dysfunction or his health. High blood pressure and medication used in treatment can affect erectile function. So can narcotics (which can also lower testosterone production). We also worry about high cholesterol clogging flow to penis. Dm?

Who know?: All possible, but to pinpoint which one is the culprit, one has to painstakingly verify, record, and correlate the timing of onset of ed with the timing of starting a drug. Meanwhile, the general health, current medical illness, lifestyle with/without overindulgence and obsession, etc. Have to be comprehensively assessed so a reasonable accurate diagnosis can be reached for proposing treatment.
