Low libido describes a decreased interest in sexual activity. It’s common to lose interest in sex from time to time, and libido levels vary through life. It’s also normal for your interest not to match your08-low-sex-drive-medication-drugs partners at times. However, low libido for a long period of time may cause concern for some people. Low libido can sometimes be an indicator of underlying health conditions. Taking certain medications can lower testosterone levels, which in turn may lead to low libido. For example, blood pressure medications like ACE inhibitors and beta-blockers may prevent ejaculation and erections. If you’re experiencing these effects of low testosterone, talk to your doctor. They may advise you to switch medications.
