high blood pressure
"I was on this for a month. I also have COPD. I have been getting weak, couldn't walk farther than a few steps without having to rest and totally exhausted about an hour after taking this medicine. Dr. thought my COPD was getting worse but couldn't control it. I remembered I started feeling this way right after being switched from Metoprolol to this medicine. I refused to take it again and after missing two doses, I can breath and walk again. Back on Metoprolol."
