Toprol (metoprolol) and the side effects?

Possible side effect: Possible side effects of beta-blockers include: sexual dysfunction in males, HDL reduction, increased triglycerides, bronchoconstriction if non-selective beta-blocker leading to shortness of breath, bradycardia, hypotension, heart block, fatigue, and dizziness. However, don't forget that most people do fine, or have a brief adjustment period then are fine. Talk w/ ur doc to see if benefits>risks.
