About cyclopenthiazide
Type de médicament | A thiazide diuretic |
Utilisé pour | High blood pressure; fluid retention; heart failure |
Également appelé | Navidrex®, Navispare® (discontinued) |
Disponible en | Tablettes |
Cyclopenthiazide belongs to a group of medicines called thiazide 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 high blood pressure (hypertension). They are also used to clear excess fluid from your body in conditions where your body retains more than it needs. This is called oedema. Cyclopenthiazide is also useful in people who have heart failure. Heart failure is a condition where your heart is not functioning as well as it should.
Diuretics like cyclopenthiazide work by interfering with the transport 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.
Cyclopenthiazide is usually given alongside other diuretics to treat high blood pressure. When it is used like this, you may be prescribed a combination tablet, such as Navispare®. This brand contains cyclopenthiazide with amiloride. Combination tablets like this help to reduce the number of tablets you need to take each day.
Before taking cyclopenthiazide
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking cyclopenthiazide it is important that your doctor knows:
Si vous êtes enceinte ou si vous allaitez.
Si vous avez des problèmes de fonctionnement du foie ou des reins.
If you have gout, diabetes or an inflammatory condition called systemic lupus erythematosus (also called lupus, or SLE). These conditions can be made worse by medicines like cyclopenthiazide.
Si un médecin vous a dit que vous aviez un faible taux de sodium ou de potassium dans le sang, ou un taux élevé de calcium dans le sang.
Si vous avez un problème avec vos glandes surrénales, appelé maladie d'Addison.
Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.
Si vous avez déjà eu une réaction allergique à un médicament.

How to take cyclopenthiazide
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about cyclopenthiazide and will provide you with a full list of the side-effects which you may experience from taking it.
Take cyclopenthiazide tablets exactly as your doctor tells you to. The usual dose is ½-1 tablet daily. 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 you needing to get up to go to the toilet during the night.
Swallow the tablet with a drink of water. You can take it either with or without food.
If you forget to take a dose, take it as soon as you remember. However, if it is late afternoon when you remember, leave out the forgotten dose and take your next dose as usual on the following day. Do not take two doses on the same day to make up for a missed dose.
Tirer le meilleur parti de votre traitement
'Water tablets' (diuretics) like cyclopenthiazide help you to lose water. Occasionally you may lose too much and become lacking in fluid in the body (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 cyclopenthiazide and your doctor may want you to have a blood test from time to time to check for this.
If you have been prescribed cyclopenthiazide for high blood pressure (hypertension), 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, so it is important that you continue to take the tablets regularly to help reduce the risk of this. You may also be given some lifestyle and dietary advice by your doctor, such as stopping smoking, reducing the amount of salt in your diet, eating more fruit and vegetables and less saturated fat, and taking some regular exercise. Following this advice will also help to reduce the risk of damage to your heart and blood vessels.
Ask your doctor for advice before drinking alcohol while you are on cyclopenthiazide. Alcohol will add to the blood pressure-lowering effect of cyclopenthiazide 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 to take alongside cyclopenthiazide.

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 cyclopenthiazide. 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.
Common cyclopenthiazide side-effects | Que puis-je faire si je suis confronté à cette situation ? |
Sensation de malaise (nausée), maux d'estomac | This is usually mild, but it may help to take cyclopenthiazide after food if you are not already doing so |
Sensation de vertige, en particulier lorsque vous vous levez (en raison d'une tension artérielle trop basse) | Getting up more slowly should help. Do not drive and do not use tools or machines while affected |
Si vous ressentez d'autres symptômes qui pourraient être dus aux comprimés, demandez conseil à votre médecin ou à votre pharmacien.
