Chlortalidone belongs to a group of medicines called thiazide-related diuretics. A diuretic is a medicine which increases the amount of urine that you pass out from your kidneys. They are often referred to as 'water tablets'. Diuretics are a common treatment for לחץ דם גבוה (יתר לחץ דם). They are also used to clear excess fluid in some liver and kidney conditions where the body retains more fluid than it needs. Chlortalidone is also useful in people who have אי ספיקת לב. Heart failure is a condition where the heart does not function as well as it should.

Diuretics like chlortalidone work by interfering with the movement of salt and water across certain cells in your kidneys. The effect of this is to make your kidneys pass out more urine. The removal of fluid reduces your blood pressure and helps reduce the work your heart has to do. Chlortalidone tends to have only a weak action on the kidneys, so it is unlikely you will notice a great increase in urine.

Chlortalidone may also be given alongside other medicines used to treat fluid retention and/or hypertension. When it is used like this, you may be prescribed a combination tablet. Combination tablets help to reduce the total number of tablets you need to take each day.

Chlortalidone tablets may also be of benefit to people with diabetes insipidus. This is a condition where a person produces large amounts of dilute urine and is constantly thirsty. How chlortalidone works in diabetes insipidus is not fully understood.

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 chlortalidone it is important that your doctor knows:

  • אם את בהריון או מניקה.

  • If you have kidney or liver problems.

  • If you have gout, diabetes, or an inflammatory condition called lupus or SLE (systemic lupus erythematosus). These conditions may be made worse by diuretics.

  • If you have been told by a doctor that you have low sodium or potassium levels in your blood, or high calcium levels in your blood.

  • If you have a problem with your adrenal glands, called מחלת אדיסון.

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

  • אם אי פעם הייתה לך תגובה אלרגית לתרופה.

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about the tablets and a full list of side-effects which you may experience from taking them.

  • Take chlortalidone exactly as your doctor tells you to. The usual dose is ½-1 tablet daily (25-50 mg), although your dose may be different to this. Your doctor is likely to recommend that you take your dose in the morning. This is so it works during the day and your sleep is not disturbed by needing to get up to make extra trips to the toilet during the night.

  • Although you can take the tablets before or after food, you are recommended to take them after a meal (usually breakfast). This is because the food in your stomach will help to reduce the side-effect of stomach upset.

  • If you forget to take a dose, take it as soon as you remember. However, if it is after 6 pm in the evening, you should skip the forgotten dose and continue as usual the next day. Do not take two doses together to make up for a missed dose.

  • Diuretics like chlortalidone help you to lose water. Occasionally you may lose too much and become dehydrated. Let your doctor know if you feel constantly thirsty, your mouth is dry, or your skin looks and feels dry.

  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. The salt balance in your bloodstream may be upset by chlortalidone and your doctor may want you to have a blood test from time to time to check for this.

  • If you have been prescribed chlortalidone for high blood pressure, your treatment is likely to be long-term. Although many people with high blood pressure do not feel unwell, if left untreated, high blood pressure can harm your heart and damage your blood vessels. This damage may later result in a heart attack, stroke, or kidney problems. It is important that you continue to take chlortalidone regularly to help reduce the risk of this.

  • You may also be given some lifestyle or dietary advice by your doctor, such as stopping smoking, reducing the amount of salt in your diet and taking some regular exercise. Following this advice will help to reduce the risk of damage to your heart and blood vessels.

  • Drinking alcohol while you are on chlortalidone may make you feel dizzy. Ask for your doctor's advice about whether you should avoid alcohol.

  • If you buy any medicines, check with a pharmacist that they are suitable to take alongside chlortalidone.

  • אם אתה עובר ניתוח או טיפול שיניים, אמור לאדם שמבצע את הטיפול אילו תרופות אתה נוטל.

  • If you have diabetes (diabetes mellitus), chlortalidone may affect your blood sugar (glucose) levels. Test your blood or urine regularly and speak with your doctor if you notice any significant changes.
