Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.
Angina: People with coronary artery disease may experience worsening of angina (chest pain) if they stop taking bisoprolol suddenly. If you want to stop taking the medication, talk to your doctor about how to do this safely by gradually reducing the dose over time.
Lung, heart, or circulation problems: If you have circulation problems, asthma, bronchitis, any other lung disease, or a history of heart failure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Hyperthyroidism: Bisprolol may mask the signs of thyroid overactivity. If it is stopped suddenly, it may cause a worsening of the symptoms of hyperthyroidism (overactive thyroid). Do not stop the medication on your own. Instead, talk to your doctor about how to safely stop the medication by gradually reducing the dose over time.
Diabetes: Bisoprolol may mask some symptoms of low blood sugar. If you have diabetes, your doctor should closely monitor your condition while you are taking bisoprolol.
Impaired kidney or liver function: Your doctor may recommend laboratory tests to check your kidney and liver function while you are on this medication.
Occupational hazards: Bisoprolol may cause drowsiness and lightheadedness. Avoid anything that requires you to be awake and alert until you know how the medication affects you.
Stopping the medication: Do not stop taking bisoprolol suddenly - check with your doctor first. Your doctor can advise you on how to stop the medication safely.
Surgery: Before surgery (including dental surgery), tell the doctor or dentist that you are taking bisoprolol.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if bisoprolol passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
