I am a 41 yr old female who has been taking 25mg of Toprol for almost 2 months for high BP. I immediately started experiencing chest pains and muscle pain on my left leg. Doctor told me she doubted if it was caused by the Toprol. EKG, ECHO did not show any abnormally with heart. I reduce dosage to pill (12.5 mg) and side effects are almost gone. My BP has never been better 110/70. But I have noticed a reduction on my sex drive these past 2 weeks - could it be the Toprol??
