What it is and what it is used for

for Hylaton Tablets belong to a group of medicines called thiazide diuretics. Thiazide diuretics help to reduce the amount of water in your body. They do this by increasing the amount of water that you pass as urine. They are sometimes called 'water tablets'. Hylaton Tablets are used to:

  • treat high blood pressure (hypertension)
  • treat heart failure
  • help reduce the fluid retention that occurs with some kidney or liver diseases
  • treat diabetes insipidus (a condition in which an individual produces large amounts of dilute urine and is constantly thirsty).

What you need to know before you take it

e Hylaton Tablets Do not take Hylaton Tablets:

  • if you are allergic to Hylaton or sulphonamides such as sulfamethoxazole or any of the other ingredients of this medicine (see Section 6. Contents of the pack and other information)
  • if you are not passing any urine at all
  • if you have severe kidney or liver problems
  • if you have low blood levels of potassium which can cause muscle weakness, muscle twitching or abnormal heartbeat
  • if you have low blood levels of sodium which can cause tiredness, confusion, muscle twitching, fits or coma
  • if you have high blood levels of calcium which can cause loss of appetite, tiredness or muscle weakness
  • if you have ever had gout or kidney stones
  • if you have Addison's disease (which is a condition where your adrenal gland is not producing enough steroids)
  • if you are taking lithium. If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take Hylaton Tablets. Warnings and precautions Talk to your doctor, pharmacist or nurse before taking Hylaton Tablets:
  • if you suffer from any other liver or kidney problems;
  • if you are on a low-salt diet;
  • if you suffer from diabetes mellitus (increased levels of sugar in the blood);
  • if you have high cholesterol levels;
  • if you have recently had an anaesthetic;
  • if you are elderly.
  • If you experience a decrease in vision or eye pain. These could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or an increase of pressure in your eye and can happen within hours to a week of taking Hylaton Tablets. This can lead to permanent vision loss, if not treated. If you earlier have had a penicillin or sulphonamide allergy, you can be at higher risk of developing this. If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take Hylaton Tablets.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Treatment of arterial hypertension, essential or nephrogenic or isolated systolic.

Treatment of stable, chronic heart failure of mild to moderate degree (New York Heart Association, NYHA: functional class II or III)

Oedema of specific origin

Ascites due to cirrhosis of the liver in stable patients under close control. Oedema due to nephrotic syndrome.

Diabetes Insipidus.

4.2. Posology and method of administration

Posology

The dosage of Hylaton / Chlortalidone Tablets should be individually titrated to give the lowest effective dose; this is particularly important in the elderly.

Chlortalidone should be taken orally, preferably as a single daily dose at breakfast time.

Adults:

Hypertension

The recommended starting dose is 25mg/day. This is sufficient to produce the maximum hypotensive effect in most patients. If the decrease in blood pressure proves inadequate with 25mg/day, then the dose can be increased to 50mg/day.

If a further reduction in blood pressure is required, additional hypertensive therapy may be added to the dosage regime.

Stable, chronic heart failure (NYHA: functional class II /III):

The recommended starting dose is 25 to 50mg/day. In severe cases it may be increased up to 100 -200 mg/day. The usual maintenance dose is the lowest effective dose, e.g. 25- 50 mg/day either daily or every other day. If the response proves inadequate, digitalis or an ACE inhibitor, or both, may be added. (See Section 4.4 “Special warnings and precautions for use”).

Oedema of specific origin (see Section 4.1 “Therapeutic indications”)

The lowest effective dose is to be identified by titration and administered over limited periods only. It is recommended that doses should not exceed 50mg/day.

Diabetes insipidus

Initially 100 mg twice daily but reducing where possible to a daily maintenance dose of 50 mg.

Paediatric population

The lowest effective dose should also be used in children. For example, an initial dose of 0.5 to 1 mg/kg/48hours and a maximum dose of 1.7 mg/kg/48hours have been used.

Elderly patients and patients with renal impairment:

The lowest effective dose of Hylaton /Chlortalidone Tablets is also recommended for patients with mild renal insufficiency and for elderly patients (see Section 5.2 “Pharmacokinetic properties”).

In elderly patients, the elimination of chlortalidone is slower than in healthy young adults, although absorption is the same. Therefore, a reduction in the recommended adult dosage may be needed. Close medical observation is indicated when treating patients of advanced age with chlortalidone.

Chlortalidone and the thiazide diuretics lose their diuretic effect when the creatinine clearance is <30ml/min.

4.3. Contraindications

Known hypersensitivity to chlortalidone or any of the excipients. Anuria, severe hepatic or renal failure (creatinine clearance <30ml/min), hypersensitivity to chlortalidone and other sulphonamide derivatives, refractory hypokalaemia, hyponatraemia and hypercalcaemia, symptomatic, hyperuricaemia (history of gout or uric acid calculi), hypertension during pregnancy, untreated Addison's disease and concomitant lithium therapy.

4.4. Special warnings and precautions for use

Warnings:

Hylaton / Chlortalidone Tablets should be used with caution in patients with impaired hepatic function or progressive liver disease since minor changes in the fluid and electrolyte balance due to thiazide diuretics may precipitate hepatic coma, especially in patients with liver cirrhosis (see Section 4.3 “Contra-indications”).

Chlortalidone should also be used with caution in patients with severe renal disease. Thiazides may precipitate azotaemia in such patients, and the effects of repeated administration may be cumulative.

Choroidal effusion, acute myopia and secondary angle-closure glaucoma:

Sulfonamide or sulfonamide derivative drugs can cause an idiosyncratic reaction resulting in choroidal effusion with visual field defect, transient myopia and acute angle-closure glaucoma. Symptoms include acute onset of decreased visual acuity or ocular pain and typically occur within hours to weeks of drug initiation. Untreated acute angle-closure glaucoma can lead to permanent vision loss. The primary treatment is to discontinue drug intake as rapidly as possible. Prompt medical or surgical treatments may need to be considered if the intraocular pressure remains uncontrolled. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy.

Precautions:

Electrolytes:

Treatment with thiazide diuretics has been associated with electrolyte disturbances such as hypokalaemia, hypomagnesaemia, hypercalcemia and hyponatraemia. Since the excretion of electrolytes is increased, a very strict low-salt diet should be avoided.

Hypokalaemia may increase the excitability of the heart or exaggerate its response to the toxic effects of digitalis.

Like all thiazide diuretics, kaluresis induced by chlortalidone is dose dependent and varies in extent from one subject to another. With 25 to 50 mg/day, the decrease in serum potassium concentrations averages 0.5mmol/l.

Periodic serum electrolyte determinations should be carried out, particularly in digitalised patients.

If necessary, Hylaton / Chlortalidone Tablets may be combined with oral potassium supplements or with a potassium- sparing diuretic (e.g. triamterene).

If hypokalaemia is accompanied by clinical signs (e.g. muscular weakness, paresis and ECG alteration), Hylaton / Chlortalidone Tablets should be discontinued.

Combined treatment consisting of Hylaton / Chlortalidone Tablets and a potassium salt or a potassium-sparing diuretic should be avoided in patients treated with ACE inhibitors.

Monitoring of serum electrolytes is particularly indicated in the elderly, in patients with ascites due to liver cirrhosis, and in patients with oedema due to nephrotic syndrome. There have been isolated reports of hyponatraemia with neurological symptoms (e.g. nausea, debility, progressive disorientation and apathy) following thiazide treatment.

For nephrotic syndrome, chlortalidone should be used only under close control in normokalaemic patients with no signs of volume depletion.

Metabolic effects:

Chlortalidone may raise the serum uric acid level, but attacks of gout are uncommon during chronic treatment.

As with the use of other thiazide diuretics, glucose intolerance may occur; this is manifest as hyperglycaemia and glycosuria. Chlortalidone may very seldom aggravate or precipitate diabetes mellitus; this is usually reversible on stopping therapy.

Small and partly reversible increases in plasma concentrations of total cholesterol, triglycerides, or low- density lipoprotein cholesterol were reported in patients during long-term treatment with thiazides and thiazide-like diuretics. The clinical relevance of these findings is a matter for debate.

Hylaton / Chlortalidone Tablets should not be used as a first-line drug for long-term treatment in patients with overt diabetes mellitus or in subjects receiving therapy for hypercholesterolaemia (diet or combined).

As with all antihypertensive agents, a cautious dosage schedule is indicated in patients with severe coronary or cerebral arteriosclerosis.

Other effects:

The antihypertensive effect of ACE inhibitors is potentiated by agents that increase plasma renin activity (diuretics). It is recommended that the diuretic be reduced in dosage or withdrawn for 2 to 3 days and/or that the ACE inhibitor therapy be started with a low initial dose of the ACE inhibitor. Patients should be monitored for several hours after the first dose.

Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

4.5. Interaction with other medicinal products and other forms of interaction

Diuretics potentiate the action of curare derivatives and antihypertensive drugs (e.g. guanethidine, methyldopa, β-blockers, vasodilators, calcium antagonists and ACE inhibitors).

The hypokalaemic effect of diuretics may be potentiated by corticosteroids, ACTH, ß2 – agonists, amphotericin and carbenoxolone.

It may prove necessary to adjust the dosage of insulin and oral anti-diabetic agents.

Thiazide-induced hypokalaemia or hypomagnesaemia may favour the occurrence of digitalis-induced cardiac arrhythmias (see Section 4.4 “Special warnings and precautions for use”).

Concomitant administration of certain non-steroidal anti-inflammatory drugs (e.g. indometacin) may reduce the diuretic and antihypertensive activity of chlortalidone; there have been isolated reports of a deterioration in renal function in predisposed patients.

The bioavailability of thiazide-type diuretics may be increased by anticholinergic agents (e.g. atropine, biperiden), apparently due to a decrease in gastrointestinal motility and stomach-emptying rate.

Absorption of thiazide diuretics is impaired in the presence of anionic exchange resins such as colestyramine. A decrease in the pharmacological effect may be expected.

Concurrent administration of thiazide diuretics may increase the incidence of hypersensitivity reactions to allopurinol, increase the risk of adverse effects caused by amantadine, enhance the hyperglycaemic effect of diazoxide, and reduce renal excretion of cytotoxic agents (e.g. cyclophosphamide, methotrexate) and potentiate their myelosuppressive effects.

The pharmacological effects of both calcium salts and vitamin D may be increased to clinically significant levels if given with thiazide diuretics. The resultant hypercalcaemia is usually transient but may be persistent and symptomatic (weakness, fatigue, anorexia) in patients with hyperparathyroidism.

Concomitant treatment with cyclosporin may increase the risk of hyperuricaemia and gout-type complications.

Thiazide and related diuretics can cause a rapid rise in serum lithium levels as the renal clearance of lithium is reduced by these compounds.

4.6. Fertility, pregnancy and lactation

Pregnancy

Diuretics are best avoided for the management of oedema or hypertension in pregnancy as their use may be associated with hypovolaemia, increased blood viscosity and reduced placental perfusion. There have been reports of foetal bone marrow depression, thrombocytopenia, and foetal and neonatal jaundice associated with the use of thiazide diuretics.

Breastfeeding

Chlortalidone passes into the breast milk; mothers taking chlortalidone should refrain from breast-feeding their infants.

4.7. Effects on ability to drive and use machines

Patients should be warned of the potential hazards of driving or operating machinery if they experience side effects such as dizziness.
