Beta blockers (beta-adrenergic blocking agents) are medications used for the treatment of high blood pressure, glaucoma and migraines. According to the Mayo Clinic, when you take beta blockers, the heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers aid blood vessels in dilating to improve blood flow. Some examples of beta blockers include Metoprolol, Atenolol, Labetalol and Toprol. These medications do have adverse effects.
Fatigue and Dizziness
You may experience fatigue and dizziness while taking beta blockers. You may just seem more tired and sleepy than usual. Be careful if you drive or do anything that requires you to be awake and alert, states Drugs.com. Avoid drinking alcohol while taking a beta blocker, it may increase drowsiness and dizziness. Fatigue and dizziness may subside over time after your body has some time to adjust to your medication.
Shortness of Breath
You may experience shortness of breath while taking a beta blocker. You may notice that you are out of breath while doing daily activities. Beta blockers generally aren't used in people with asthma because of concerns that the medication may trigger severe asthma attacks, states the Mayo Clinic. If shortness of breath becomes bothersome and impacts your daily lifestyle, contact your healthcare provider.
Sexual Effects
