Nadolol - a beta-blocker

About nadolol

Nadolol belongs to the group of medicines known as beta-blockers. It is a medicine which is used to treat several different medical conditions. It works on the heart and blood vessels.

Nadolol slows down the activity of your heart by stopping messages sent by some nerves to your heart. It does this by blocking tiny areas (called beta-adrenergic receptors) where the messages are received by your heart. As a result, your heart beats more slowly and with less force. This allows the pressure of blood within your blood vessels to be reduced if you have לחץ דם גבוה (יתר לחץ דם), and helps to prevent abnormally fast heart rhythms (arrhythmias). Because your heart is using less energy, this helps to reduce chest pain if you have אנגינה.

Nadolol is also prescribed to help ease some of the symptoms of an overactive thyroid gland, such as a fast heartbeat and trembling. It relieves these symptoms quickly, which allows time for other antithyroid treatments to take effect. Nadolol is also prescribed to help stop migraines. It can be helpful for people who find other treatments to prevent migraine unsuitable.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking nadolol it is important that your doctor knows:

• אם את בהריון, מנסה להיכנס להריון או מניקה.

• If you have asthma or any other breathing disorder.

• אם יש לך בעיות בתפקוד הכבד שלך, או בתפקוד הכליות שלך.

• If you have low blood pressure or poor circulation.

• אם יש לך רמות סוכר גבוהות בדם (סוכרת).

• If you have a skin problem called psoriasis.

• If you have a condition causing muscle weakness, called myasthenia gravis.

• If you have been told you have a slow heartbeat or heart block (a slow and irregular heartbeat).

• If you have been told you have chest pain called Prinzmetal's angina (caused by spasms of your heart's blood vessels).

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• If you have ever had an allergic reaction to a medicine, or if you have ever had any other serious allergic reaction.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about nadolol and will provide you with a full list of the side-effects which you may experience from taking it.

• Take nadolol exactly as your doctor tells you to. It is usual to take one dose daily. Your doctor may prescribe you a small dose initially (half of an 80 mg tablet) and then increase your dose slowly over the next few weeks. This allows your doctor to make sure that you have the dose that helps your condition and helps to prevent unwanted side-effects. Try to take your doses at the same time of day each day, as this will help you to remember to take nadolol regularly. You can take nadolol tablets before or after meals.

• If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, miss out the forgotten dose completely. Do not take two doses at the same time to make up for a missed dose.

• נסה לשמור על הפגישות הקבועות שלך עם הרופא. זה כדי שהרופא יוכל לבדוק את ההתקדמות שלך.

• Treatment with nadolol can often be long-term. Continue to take the tablets unless your doctor tells you to stop. Stopping treatment suddenly can cause problems in some people, so your doctor may want you to reduce your dose gradually if this becomes necessary.

• If you are due to have an operation or dental treatment, it is important to tell the person carrying out the treatment that you are taking a beta-blocker. This is because some anaesthetics may increase the risk of unwanted effects.

• Ask your doctor for advice before drinking alcohol while you are on nadolol. Alcohol will add to the blood pressure-lowering effect of nadolol which will increase the possibility of you experiencing side-effects such as dizziness.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. Some medicines (including some cough, cold and flu remedies) may not be.

• Your doctor may give you dietary and lifestyle advice about eating a healthy diet, not smoking, and taking regular exercise. If so, it is important that you follow the advice you are given.

• If you have diabetes, nadolol can block the symptoms of low blood sugar. Your doctor will advise you about this.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with nadolol. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
