Beta blockers are a class of medications that are primarily used to treat cardiovascular diseases and other conditions. They work by blocking the effects of the hormone epinephrine, also known as adrenaline, which causes the heart to beat more slowly and with less force, thus lowering blood pressure. Beta blockers also help widen veins and arteries to improve blood flow. Some common uses of beta blockers include:
- High blood pressure: Beta blockers are often used to treat high blood pressure when other medications have not worked.
- Heart conditions: Beta blockers are used to prevent, treat, or improve symptoms in conditions such as irregular heart rhythms, heart failure, chest pain (angina), and heart attacks.
- Migraine: Beta blockers are sometimes used to prevent migraines.
- Tremors: Beta blockers are used to treat some types of tremors.
Examples of beta blockers include atenolol, metoprolol, propranolol, and bisoprolol. Beta blockers are prescription-only medicines and should only be prescribed by a qualified healthcare professional. It is important to tell your doctor about any other conditions you have before taking beta blockers, as they may not be suitable for everyone. Common side effects of beta blockers include fatigue, dizziness, and cold hands and feet.
