Key takeaways
Propranolol (Inderal LA, Inderal XL, Innopran XL) and bisoprolol (Zebeta) are both beta blockers used to treat high blood pressure, but they have some key differences. Propranolol is a non-selective beta blocker, meaning it affects both the heart and other parts of the body, while bisoprolol is a selective beta blocker that mainly targets the heart. Propranolol is used for a wider range of conditions, including chronic chest pain and migraines, and tremors, whereas bisoprolol is primarily used for high blood pressure. You might need to take propranolol multiple times a day depending on the form, but bisoprolol is usually taken once daily. Propranolol can cause side effects like dizziness and tiredness, and it’s not safe for people with asthma. Bisoprolol can also cause tiredness and dizziness, but it’s less likely to cause breathing problems. Both medications can hide symptoms of low blood sugar, so you need to be cautious if you have diabetes.
