Before you begin using 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 use Teva Nadolol.
Breathing problems: Nadolol may make symptoms of asthma and certain other breathing problems worse. If you have asthma, other breathing problems, or a history of breathing problems, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Diabetes: The signs of low blood sugar may not be as noticeable when you are taking nadolol. If you have diabetes and take insulin or other medications that affect blood glucose levels, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed. It may be necessary to monitor your blood glucose levels more often when you are taking Teva Nadolol.
Dizziness: Occasionally, blood pressure drops too low after taking nadolol, causing dizziness or lightheadedness. This is more likely to happen when you first start to take Teva Nadolol. To reduce the likelihood of this happening, move slowly when changing from a lying or sitting position to a standing position to reduce the severity of dizziness.
Heart failure: Taking Teva Nadolol if you have heart problems may cause the symptoms of heart disease to worsen. If you have heart failure or a history of heart disease, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Hyperthyroidism (high level of Thyroid hormones): Nadolol may reduce the symptoms of hyperthyroidism, giving a false impression that the condition is improving. If you have hyperthyroidism, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Kidney function: Kidney Disease or reduced kidney function may cause Teva Nadolol to build up in the body, causing side effects. If you have kidney problems, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Mental health: If you have a history of Depression or other psychiatric illness, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Myasthenia Gravis: The signs of worsening myasthenia gravis may not be as noticeable for people taking nadolol. If you have myasthenia gravis, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Peripheral vascular disease: Nadolol may worsen the symptoms of diseases of the blood vessels, such as Raynaud's disease. If you have a condition involving the blood vessels, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Psoriasis: Nadolol has been related to the development or worsening of psoriasis, although how this occurs is not known. If you have psoriasis or a history of psoriasis, discuss with your doctor how Teva Nadolol may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Nadolol, and whether any special monitoring is needed.
Severe allergies: Nadolol may make it more difficult to treat severe allergic reactions with Epinephrine. If you have allergies that are severe enough to cause Anaphylaxis (severe allergic reaction) (a severe allergic reaction where swelling of the face, lips, and throat make it difficult to breathe), talk to your doctor about what to do if you have an allergic reaction.
Stopping medication: The dose of nadolol should be gradually reduced, rather than stopped suddenly. There have been reports of severe worsening of angina, and of heart attack or abnormal heart rhythms occurring for people with angina pectoris who have stopped Teva Nadolol without gradually reducing the dose. Discuss the risks and benefits of stopping nadolol with your doctor.
Surgery: If you are scheduled for surgery, inform all doctors involved in your care that you take nadolol. If it is planned surgery and it is necessary to stop taking nadolol before the surgery, it should be done gradually to reduce the risk of chest pain and increased blood pressure.
Pregnancy: Teva Nadolol should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Teva Nadolol, contact your doctor immediately.
Breast-feeding: Teva Nadolol passes into breast milk. If you are a breast-feeding mother and are taking nadolol, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using Teva Nadolol have not been established for children.
Seniors: Seniors are at an increased risk of experiencing the side effects of nadolol. The starting dose and maximum daily dose may be lower for this population.
