Bisoprolol, or bisoprolol fumarate, is a tablet that's used to treat high blood pressure. It belongs to a group of medications called beta blockers. It's usually only given when first-choice blood pressure medications aren't working well enough. Some common side effects of bisoprolol include headache, feeling tired, and diarrhea. It has some interactions with alcohol and taking bisoprolol with alcohol can worsen dizziness and raise the risk for fainting.
High blood pressure
Bisoprolol is a selective beta blocker. It works to lower blood pressure by slowing down the heart rate to give your heart some time to relax between contractions.

Bisoprolol works the best when you take it consistently every day. Don't stop taking bisoprolol suddenly without talking to your healthcare provider as this could make chest pain or other heart conditions (such as coronary artery disease) worse. If you want to stop the medication, speak with your healthcare provider. They can work with you to lower your dose safely over time (which typically occurs over 1-2 weeks).
Bisoprolol can make you feel dizzy for a few days after first starting it or changing the dose. Be sure to change positions slowly (going from sitting to standing or from lying down to sitting up). Also, make sure you know how this medication affects you before driving or performing activities that require you to be alert, such as driving.
It might be helpful to check and record your blood pressure at home. You can bring your notes to your next appointment so your provider can see how well bisoprolol is working to lower your blood pressure.
Bisoprolol can interact with other medications. Be sure to tell your provider all of the medications you're taking, and check with them before starting any new medications.
Both beta-blockers and medications used for anesthesia can lower your heart rate. So, if you’re planning to undergo a major surgery that requires anesthesia, tell your surgeon that you’re on bisoprolol so that they can monitor your heart closely.
Bisoprolol can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Stopping bisoprolol suddenly
Don't stop taking bisoprolol suddenly without talking to your provider first, especially if you have heart disease. Doing so can cause chest pain, irregular heart rhythm, high blood pressure, and even a heart attack. If you need to stop taking bisoprolol, work with your provider to lower your dose gradually over time, typically over 1 week.
Risk factors: Heart failure
People with heart failure shouldn't take bisoprolol if their heart failure symptoms aren’t well-managed. That’s because this medication can make your condition worse. But you might be able to take bisoprolol if your healthcare provider thinks your symptoms are under controlled. Keep in mind that, though rare, sometimes taking a beta-blocker, like bisoprolol over time might lead to heart failure even in people without this condition. Let your healthcare provider know right away if you experience symptoms of heart failure, such as fluid build-up in different areas of the body including the ankles, legs, and lungs, and difficulty breathing.
Risk factors: History of asthma or COPD
Beta-blocker medications like bisoprolol are generally not recommended for people with bronchospastic conditions, like asthma or chronic obstructive pulmonary disease (COPD), because it can trigger difficulty breathing. Bisoprolol has a lower chance of causing difficulty breathing because it works specifically on the heart, but should only be used under careful supervision of a healthcare provider if you have any conditions that can cause breathing problems.
Risk factors: Diabetes
Taking bisoprolol can make it difficult for you to identify symptoms of low blood sugar, such as fast heart beat or tremors. If you’re taking medications, like glipizide or insulin, to lower your blood sugar, you might not be able to rely on all the typical symptoms of low blood sugar (e.g., irritability, sight tremors, confusion, and fast heartbeat) to warn you of a dangerous drop in your sugar levels. Sweating might be the only symptom not affected by taking bisoprolol. Speak with your healthcare provider about when and how to monitor your blood sugar if you start bisoprolol.
Risk factors: Hyperthyroidism
Bisoprolol can hide signs of hyperthyroidism, especially a fast heart rate. It's important to talk to your provider before stopping bisoprolol suddenly, since doing so can worsen thyroid problems.
Risk factors: History of severe allergic reaction
Beta blockers like bisoprolol can lessen your response to life-saving treatments for severe allergic reactions (anaphylaxis). They can also cause your allergic reaction to be more severe than usual. Discuss all of your allergies with your provider and a plan on what to do if you experience an allergic reaction while taking bisoprolol.
Risk factors: History of peripheral artery disease
Bisoprolol can cause the symptoms of peripheral artery disease (PAD) to worsen. This can lead to worsening of blood circulation, which can result in tiredness, aching, and cramping in the legs. Be sure to tell your provider if you have PAD before starting bisoprolol because they might want to monitor you more closely.
The typical starting dose is 5 mg by mouth once daily. Your provider might raise your dose if your blood pressure is not well-controlled. The maximum daily dose is 20 mg.
Your dose might differ if you have liver or kidney problems.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Heart problems (e.g., certain types of heart block, heart failure, cardiac shock)
Chest pain (stable angina)
Lower risk of death after heart attack
Chest pain (angina)
