What are the pros and cons of toprol (metoprolol) xl (beta blocker)?

Depends: Toprol XL is an extended release beta specific blocker used for many different things. Your best easy source of information is the legally required patient information insert given with your prescription at the pharmacy. Pro-cost, effective, once a day dosing Con-extended release if you have a problem will take longer to leave your system. Effects, blood pressure, HR, TPR, C.O.

Mixed: Pros: effective in lowering BP; effective in treating and preventing fast heart rhythms; effective in patients who have Heart Failure at high doses. Cons: can cause fatigue, lethargy, and slow heart rate; can cause dizziness; can cause depression or worsen depression in some patients. I would not recommend it as first line therapy in an otherwise healthy person unless there are other issues.
