Can amitriptyline 10mg loose a mans sex drive?

Yes, side effects that have been reported are:

1. A decreased sex drive (libido)

2. Impotence: Impotence is usually defined as a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Ultimately, impotence is the repeated inability to get or keep an erection firm enough for sexual intercourse. Impotence is also known as erectile dysfunction (or ED for short).

See your health care provider to see if these side effects can be minimized by using an erectile dysfunction drug or a change of medication or both.
