Depends on what you're taking. Pain meds opiods, opiates are known to lower testosterone levels. Some antidepressants can affect libido but also some are prescribed for premature ejactulation. Its normal with certain meds to affect libido especially if you're hitting that plus 30 mark. If you are male you can ask your Doctor for testosterone if you're over 30. If you are not lookup your medication online you'll find people with the same questions. You will return to baseline once you stopped taking your meds and there are some natural ways of helping boost your test levels. I dont have the ability to PM yet so I don't know if your comfortable posting what med you're taking but I could tell you quite quickly if it does affect your libido. Hope that helps
