Joys-
I'm not a physician or pharmacist, but I have some post-graduate classes and work experience in counselling, and I have had many different anti-depressants prescribed for me and so did my late wife, so I have quite a bit of practical knowledge on the topic. Also, I just spent about 90 mins. doing more research on the Web.
I found quite a few men in other forums with the same complaint
of difficulty ejaculating while taking Seroxat (or the US brand Paxil,) and at least twice that many who had great trouble getting an erection. Several had to give up Seroxat, several were able to add a second anti-depressant to it and that helped, some found out the sexual side effects decreased the longer they used it, and some got better with a higher dose of Seroxat.
The manufacturer (oops, forgot to put their name in my notes) had the following statements that may apply to you in their company info about Seroxat:
"Men may have difficulty having an erection or may find it difficult to ejaculate. The majority of these effects will lessen with continued use of the medicine... If you have any problems while taking Seroxat, tell your doctor or pharmacist."
Of course, telling your doctor or pharmacist first is always good advice. I almost always talk to my pharmacist first, unless the side-effects I notice are something my doc has already warned me about, then I just let him know about the severity of any problems. Since your father is your psychiatrist, hopefully he can be a good source of advice for you.
Most of the anti-depressants of the "SSRI" type, including almost all of the most often prescribed ones like Seroxat and Prozac, have fairly common negative sexual effects. From reading other Web users' posts around the net, I found that many get help with sexual side effects, and often better results for their depression, by taking combinations of from 2 to as many as 5 medications and hormones. In fact, currently, I'm on 2 compatible anti-depressants, 2 hormones and 1 stimulant. (Part of my diagnosis says "medication-resistant major depression")
I'm 50 yrs old, and I certainly don't cum as quickly as I did when I was a young man, but that is really OK in my case, most of the time. It is only frustrating every once in awhile, and who knows whether this fairly seldom occurence is related to my anti-depressants or not. I've just been on my latest combination for about 4 months, and after 1 month I realized I was more horny, more often, than I had been since my mid-20s. In fact, maybe a higher sex drive than ever before. I have to admit I kind of like it!
One other thing that many people mentioned about Seroxat is that it is actually dangerous to quit taking it suddenly. I was only taking it for about 3 or 4 weeks before my doc & I realized my depression was actually worse than with my earlier meds, but even then he took me off of it by reducing my dose a little each day for about 10 days and adding in a little of another compatible anti-depressant each of those days.
I get carried away and write too much info in my posts sometimes,
but I hope this one will be of some help to you and your wife.
Take good care of yourself! RW- MrCuriousUSA
