Some of the most commonly prescribed beta-blockers include Sectral, Zebeta, Brevibloc, Inderal and Tenormin, explains WebMD. Normodyne, Coreg, Toprol-XL and Lopressor are others. There are also generic equivalents of most of these beta-blocker medications.
Doctors prescribe beta-blockers to treat high blood pressure and congestive heart failure, notes WebMD. The drugs work by blocking the adrenalineﾒs effects on the body and slowing the heart rate. This decreases the demand for oxygen on the heart and improves symptoms of high blood pressure while managing chronic heart failure symptoms when used long-term. Doctors also prescribe beta-blockers for treating other heart conditions, including abnormal heart rhythms, angina and heart attack. Other uses include treatment of hyperthyroidism, migraine headaches, glaucoma, some tremors and anxiety.
Prescribing doctors generally recommend taking beta-blockers in the morning, at bedtime or with meals, according to WebMD. Taking the medication with meals lessens any side effects. Some side effects include headache, fatigue, cold hands, constipation and upset stomach. Dizziness, diarrhea, trouble sleeping, depression and shortness of breath are additional symptoms. Some users experience erectile dysfunction and lowered sex drives during treatment.
People taking beta-blockers should report severe or persistent side effects to the prescribing physician or other medical professional. Doctors warn that people prescribed with beta-blockers should not quit taking them without consulting a doctor first, advises WebMD.
