Beta blockers (beta adrenergic-blocking agents) are medications used in the treatment of high blood pressure, heart arrhythmia, migraines and glaucoma. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline, causing the heart to beat more slowly and with less force, thereby reducing blood pressure, states Mayo Clinic. Beta blockers may be used in conjunction with other medications, diet and exercise. There are some common side effects of beta blocker medications that users should be aware of.
Headache and Dizziness
You may experience headache and dizziness while taking a beta blocker. These side effects may lessen over time, as your body adjusts to your medication. You may want to use caution while driving or completing tasks that may be dangerous until you know how your beta blocker will affect you. If headache becomes severe, ask your physician if you can take an over the counter pain medication such as acetaminophen or ibuprofen for relief. If these effects persist and worsen, speak with your healthcare provider. They may consider altering your medication regimen.
Fatigue and Nausea
Since beta blockers reduce the heart rate, they also decrease the amount of oxygen that circulates through the body causing people that take them to experience difficulty handling strenuous physical activity, reports the American Heart Association. You may feel more tired than usual and require additional time to complete daily activities. Some patients may experience nausea while taking a beta blocker. Nausea may diminish after your body adjusts to your medication. Eating smaller meals more frequently and avoiding spicy or fatty foods may help alleviate nausea.
Hypotension
You may experience hypotension (low blood pressure) while taking a beta blocker drug. Signs and symptoms of hypotension can include dizziness, lightheadedness, and fainting. If you think you may be experiencing hypotension take your blood pressure at home (if possible). If your blood pressure is lower than your normal range, contact your healthcare provider. It is possible that your dosage of medication may be too high. Your physician may ask you to not take your medication for a few days, and then begin therapy with a lower dose of medication.
