I m a 61 year old male. for 30 years I took Benazepril 20 mg twice a day, started having problems coughing, which we related back to it. so the doctor changed me to Bisoprolol/hct 5-6.25 once a day, able to perform in sex went south. We now changed to 50/12.5 once a day, but sex drive is now non existence. Is there any hope for my sex drive return. I can t do Viagra or the other one, they burn my eyes unbearably. Thanks for any advice.
