They are effecting my life style. What concerns should I have about taking toprol. He has me taken 25mg once a day. Dear Tim, Firstly, you should read the insert that came with the drug, or the pharmacy instructions that came with the prescription. Because beta blockers lower blood pressure at least a little, you should never get out of bed, nor stand up too quickly, and should you develop dizziness, lightheadedness, or near fainting, call you doctor immediately.
Any drug has the potential to cause an allergic reaction, rash, headache, dizziness and lethargy.
