If you are allergic to Metoprolol - a beta blocker - does it mean you are allergic to all beta blockers?
No, not necessarily. You may be allergic to the dyes or inactive ingredients in Metoprolol that is or may not be found in another beta blocker or even in another generic Metoprolol. You should double check with your doctor or pharmacist because there is also a chance that you may be one of the few people that cannot tolerate a beta blocker due to health conditions and other factors.
Beta blockers do not themselves treat thyroid conditions. They do help to control some of the symptoms of hypERthryoidism. Because Atenolol is most specific to the heart, it is often the best choice for many patients, with a better side effect profile than other beta blockers. However, personal medical history will best determine which beta blocker a physician may choose as there may be other conditions, medicines, etc to consider.
No, Lotrel, a medication used to treat hypertension, is part of the Calcium-Channel Blocker (CCB) class. CCB's allow the heart and blood vessels to relax by preventing calcium from entering the muscles. Beta-Blockers function differently. They reduce electrical signals from the brain to the body's sympathetic nervous system (including the heart), reducing blood pressure by slowing the heartbeat and causing it to pump less forcefully.
