Beta blockers cause your heart to beat more slowly and with less force, which lowers blood pressure. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). This helps the person to get over his/her feelings of performance, stage fright, test anxiety, mathematical anxiety, etc. It is also used to treat or prevent heart attack, and to reduce the severity and frequency of migraine headaches. However, prescription and OTC (over-the-counter) beta blocker drugs have a few side effects associated with them. Propranolol is used to treat tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. Pharmaceutical beta-blockers are strictly prescription medicines; this means that you cannot buy them over the counter. Over the Counter Natural Beta Blockers are used to treat Anxiety, Adrenaline, Panic Attacks and Depression.How do they work? Many people wonder whether they can get over the counter beta-blockers. Natural beta-blockers however, do not need a doctor’s prescription and you can get them online and from health food retailers. Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Atenolol, in particular, is good for regulating heart problems and blood pressure as it only targets only the heart – not other areas of the body. Which Alternatives are Best?

Beta blockers block norepinephrine and epinephrine (adrenaline) from binding to beta receptors on nerves. Selective beta blockers, for example, metoprolol (Lopressor, Toprol XL) primarily block β1 receptors and, therefore, mostly affect the heart and do not affect air passages. Propranolol is a beta-blocker. Non-selective beta blockers, for example, propranolol (Inderal), block β1 and β2 receptors and, therefore, affect the heart, blood vessels, and air passages. Propranolol and Atenolol are both beta-blockers and can both used to lower blood pressure and control heart rate. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline.
