Bisoprolol is a beta-blocker many doctors prescribe for high blood pressure, angina (chest pain), and certain types of heart failure. It slows your heart rate and reduces the force of each beat, so your heart uses less oxygen and your blood pressure drops. Because it works steadily over 24 hours, most people take it once a day.
For high blood pressure, typical starting doses are 5 mg once daily, often adjusted to 10 mg if needed. For chronic heart failure, doctors usually start much lower—often 1.25 mg daily—and slowly increase the dose over weeks while watching your heart and blood pressure. Your doctor will pick the dose that fits your health, kidney function, and other medicines.
Take bisoprolol at the same time each day, with or without food. If you miss a dose, take it when you remember unless it's almost time for the next one—then skip the missed dose. Don’t double up.
Common side effects include tiredness, dizziness, cold hands or feet, and a slower pulse. Most people find these ease after a few days or weeks. Serious problems are less common but need quick attention: marked dizziness, fainting, very slow heartbeat (under about 50 bpm), chest pain, or breathing trouble.
Important cautions: if you have asthma or severe COPD, bisoprolol can make breathing worse. People with diabetes should know beta-blockers can mask symptoms of low blood sugar (like fast heartbeat). Tell your doctor if you have heart conduction problems, severe peripheral artery disease, or low blood pressure before starting.
Drug interactions matter. Combining bisoprolol with certain calcium-channel blockers (verapamil, diltiazem) or digoxin can slow the heart too much. Other blood pressure medicines, some antidepressants, and certain antiarrhythmics can add effects. Always give your pharmacist or doctor a full medicine list.
Never stop bisoprolol suddenly. Stopping quickly can cause rebound high blood pressure, chest pain, or irregular heartbeat. If you need to stop, your doctor will advise a gradual taper over days to weeks.
Before and during treatment, your doctor may check blood pressure, heart rate, and sometimes kidney function. If you have severe kidney problems, doses may be adjusted. Pregnant or breastfeeding? Talk with your provider—bisoprolol may need special consideration.
