Can Sertraline Cause Sexual Dysfunction?
Likely is due to the Sertraline.
Detailed Answer:
Hello XXXXXXX
Of the 3 medications your wife takes, I suspect the Sertraline to be causing the problem. Sertraline is an SSRI (selective serotonin re-uptake inhibitor) and this class of medication is notorious for causing sexual dysfunction, particularly failure to have orgasm, in both sexes.
I have noted that she has been taking the Sertraline for 9-12 months without problem until about 3-4 months ago. That is still the most likely cause. It can take months before this problem starts in some people. It may also be, if the other medications have been added more recently, that they are increasing the blood levels or side effects of the Sertraline. In particular, the bupropion may compound the side effects of the Sertraline.
I don't know that I would look much further into the problem of anorgasmia as being due to something else as long as she is on the Sertraline, as SSRIs are truly a common cause of this problem. I recommend she discuss this with her doctor, and possibly the dose can be lowered or a medication change might be considered.
I hope this information helps. Please let me know if I can provide further information.
