I am a 40-year-old female taking 50mg/day of Toprol (for HBP) and have experienced the following side effects:
Fatigue
Lethargy
Pain in legs and arms
Loss of breath (even when walking very short distances)
Odd dreams/nightmares
Rapid weight gain (despite no change in eating/exercising habits)
Unusually heavy menstrual flow
Nosebleeds
The cure is worse than the disease! :-(
