- Stopping bisoprolol warning: Bisoprolol lowers your heart rate and blood pressure. Suddenly stopping bisoprolol can worsen your heart condition, especially if you have coronary artery disease. It may also cause changes in heart rhythm or blood pressure, worsened chest pain, and heart attack. If you’re stopping this drug, your doctor will slowly lower your dosage over at least 1 week to help prevent these side effects.
- Diabetes warning: Bisoprolol can mask the signs of low blood sugar (hypoglycemia). Use it with caution if you have diabetes, especially if you take insulin or other diabetes drugs that can cause low blood sugar.
- Heart failure risk: Bisoprolol decreases some heart actions. This can cause or worsen heart failure. If you develop heart failure, your doctor may slowly stop your treatment with bisoprolol. If you have heart failure that’s treated with other medications, you may still be able to take bisoprolol.
Bisoprolol oral tablet is a prescription drug that’s only available in a generic form. Generic drugs usually cost less than the brand-name version. Bisoprolol is no longer available as the brand-name drug Zebeta.
Bisoprolol only comes as an oral tablet.

Bisoprolol oral tablet can interact with other medications, herbs, or vitamins you might be taking. That’s why your doctor should manage all of your medications carefully. If you’re curious about how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.
Note: You can reduce your chances of drug interactions by having all of your prescriptions filled at the same pharmacy. That way, a pharmacist can check for possible drug interactions.
Examples of drugs that can cause interactions with bisoprolol are listed below.
Heart rhythm drugs
These heart rhythm drugs may cause a lower heart rate or more side effects. If you take these drugs with bisoprolol, you’ll be monitored closely. Your doctor might change the dosage of your heart rhythm drugs. Examples of these drugs include:
Bisoprolol should not be used with another beta-blocker because your heart rate can be lowered too much. Examples of these drugs include:
Calcium channel blockers
- Dihydropyridine calcium channel blockers: Using these drugs with bisoprolol may cause a drop in your blood pressure when you change position from sitting to standing or from lying down to sitting. This raises your risk of falls. Examples of these drugs include:
- Non-dihydropyridine calcium channel blockers: Using verapamil with bisoprolol can cause severe heart block, low heart rate, changes in how your heart works, heart failure, and low blood pressure. If you have poor function of your heart ventricles, you should not use these drugs together.
- Bisoprolol and diltiazem have similar action on the heart. Using one of these drugs with bisoprolol can cause heart failure, a heart rate that’s lower than normal, low blood pressure, problems with how the heart works, and heart block.
Blood pressure drugs
- Clonidine. If you’re starting bisoprolol and stopping clonidine, your blood pressure can severely increase. If you’re on both medications and are going to stop taking clonidine, your doctor should stop bisoprolol several days before stopping clonidine.
- Reserpine and guanethidine: Using these drugs with bisoprolol may cause a drop in your blood pressure when you change position from sitting to standing or from lying down to sitting. This can increase your risk of falls.
Using rifampin with bisoprolol can speed up the rate at which bisoprolol leaves your body. This can prevent bisoprolol from working as well as it should.
Using these drugs with bisoprolol may cause a drop in your blood pressure when you change position from sitting to standing or from lying down to sitting. This raises your risk of falls. Examples of these drugs include:
Bisoprolol might affect how lidocaine is cleared from your body. This can cause lidocaine toxicity. Your doctor may check your blood levels if you use these drugs together.
Using mefloquine with bisoprolol can cause heart rhythm abnormalities and your heart may stop working.
Don’t use these drugs with bisoprolol. If you take them together, they will cancel out the action of each other and won’t work. Examples of these drugs include:
Over-the-counter cough, cold, allergy, and pain drugs
Don’t take these drugs without talking to your doctor or pharmacist. Some over-the-counter drugs contain ingredients that can increase your blood pressure. Other drugs may cancel out the action of bisoprolol. Examples of these drugs include:
- products containing phenylephrine, such as:
- Sudafed PE
- Mucinex Sinus-Max
- Advil Congestion Relief
- Tylenol Cold Multi-Symptom
- products containing pseudoephedrine, such as:
- Sudafed Congestion
- Sudafed 12 Hour
- Sudafed 24 Hours
Nonsteroidal anti-inflammatory drugs (NSAIDs)
These drugs may decrease the blood pressure-lowering effects of bisoprolol. If you take them with bisoprolol, your doctor will likely monitor your blood pressure and change your bisoprolol dosage if needed. Examples of these drugs include:

This drug comes with several warnings.
This drug can cause a severe allergic reaction. Symptoms can include:
- rash or hives
- blistering or peeling skin
- problems breathing or chest tightness
- swelling of your mouth, face, lips, tongue or throat
Call 911 or go to the nearest emergency room if you develop these symptoms. Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).
Alcohol lowers your blood pressure. Drinking alcohol while taking bisoprolol may lower your blood pressure to dangerously low levels.
Warnings for people with certain health conditions
For people with heart problems: Don’t take this drug if you have problems with pumping blood to your body, active heart failure, second or third degree heart block, or slow heart rate (bradycardia). If you have one of these conditions, your heart is already having trouble working properly. Taking bisoprolol could make your condition worse by making it harder for your heart to pump blood effectively.
If you have heart failure that’s being treated with medication (compensated heart failure), this drug could worsen your heart failure.
For people with peripheral vascular disease: This drug could worsen the symptoms of your condition.
For people with lung diseases: In general, you shouldn’t take bisoprolol if you have asthma or other breathing problems. However, your doctor may allow you to take it if you can’t tolerate other medications that treat high blood pressure. Your doctor will give you the lowest possible dosage of bisoprolol. You should have a beta-agonist inhaler, such as albuterol, available.
For people with diabetes: Bisoprolol can mask the symptoms of low blood sugar (hypoglycemia). Bisoprolol may also slow how long it takes for your blood sugar levels to rise to normal levels. Bisoprolol should be used with caution if you have diabetes, especially if you’re taking insulin or other diabetes medications that cause low blood sugar.
For people with hyperactive thyroid: Bisoprolol can mask the symptoms of a hyperactive thyroid (hyperthyroidism). If you suddenly stop taking bisoprolol, your hyperthyroidism symptoms could get worse or you may get a serious condition called thyroid storm.
For people with a cough, cold, allergies, or pain: Talk to your doctor or pharmacist. They can help you find medication that you can use safely when you’re taking bisoprolol.
Warnings for other groups
For pregnant women: Bisoprolol is a category C pregnancy drug. That means two things:
- Research in animals has shown adverse effects to the fetus when the mother takes the drug.
- There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.
Tell your doctor if you’re pregnant or plan to become pregnant. Bisoprolol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Call your doctor right away if you become pregnant while taking this drug.
For women who are breastfeeding: It isn’t known if bisoprolol passes into breast milk. If it does, it may cause serious effects in a breastfeeding child. You and your doctor should decide if you’ll take bisoprolol or breastfeed.
For children: It has not been established that bisoprolol is safe and effective for use in people under the age of 18 years.
For people having surgery: Tell your doctor if you’re going to have surgery. They’ll need to monitor your heart and blood pressure and watch for drug interactions.
