Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using APO-Candesartan HCTZ Tablets.

What is in this leaflet

Read this leaflet carefully before taking your medicine. This leaflet answers some common questions about candesartan cilexetil and hydrochlorothiazide (HCTZ). It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

The information in this leaflet was last updated on the date listed on the last page. More recent information on this medicine may be available.

Ask your doctor or pharmacist:

  • if there is anything you do not understand in this leaflet,
  • if you are worried about taking your medicine, or
  • to obtain the most up-to-date information.

All medicines have risks and benefits. Your doctor has weighed the risks of you using this medicine against the benefits they expect it will have for you.

Keep this leaflet with your medicine. You may want to read it again.

What this medicine is used for

The name of your medicine is APO-Candesartan HCTZ tablets. It contains the active ingredients candesartan cilexetil and hydrochlorothiazide.

It is used to treat:

  • high blood pressure, also called hypertension.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

They may differ from the information contained in this leaflet.

Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor's prescription.

How it works

Candesartan cilexetil is a type of medicine called an angiotensin II receptor inhibitor (or antagonist). It mainly works by causing relaxation of blood vessels.

Hydrochlorothiazide is a type of medicine called a diuretic. It works by reducing the amount of excess fluid in the body.

Using these two medicines together will lower your blood pressure more effectively than using either one on its own.

There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children. The safety and effectiveness of this medicine in children under 18 years of age have not been established.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist carefully.

Their instructions may be different to the information in this leaflet.

If you are not sure how to take this medicine, ask your doctor or pharmacist for help.

How much to take

Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

The usual dose is one tablet once daily.

How to take it

Swallow the tablets whole with a glass of water.

When to take it

Take this medicine once a day, at about the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.

It does not matter if you take it before, with or after food.

How long to take it

Continue taking this medicine for as long as your doctor tells you.

This medicine controls your condition, but does not cure it. Therefore you must take this medicine everyday. It is important to keep taking your medicine for as long as your doctor tells you to.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If you forget to take a dose, take it as soon as you remember, as long as it is at least 12 hours before your next dose is due.

Then go back to taking it as you would normally.

If it is less than 12 hours to your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too many candesartan HCTZ tablets, you may get a headache, feel sick (nausea), dizzy, thirsty and very tired.

While you are taking this medicine

Things you must do

Treatment with hydrochlorothiazide, particularly long-term use with high doses, may increase the risk of some types of skin and lip cancer (nonmelanoma skin cancer). Limit exposure to sunlight and protect your skin when exposed to sun.

If you develop any severe shortness of breath or difficulty breathing after taking this medicine, seek medical attention immediately.

Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.

4 Clinical Particulars

4.9 Overdose

Symptoms. Based on pharmacological considerations, the main manifestation of an overdose of candesartan cilexetil is likely to be symptomatic hypotension and dizziness. In two case reports of overdose (160 mg and 432 mg candesartan cilexetil), patient recovery was uneventful.
The main manifestation of an overdose of hydrochlorothiazide is acute loss of fluid and electrolytes. Symptoms such as dizziness, hypotension, thirst, tachycardia, ventricular arrhythmias, sedation/impairment of consciousness and muscle cramps can also be observed.
Management. No specific information is available on the treatment of overdosage with candesartan HCTZ. The following measures are, however, suggested in case of overdosage.
Administration of activated charcoal with or without gastric lavage. If symptomatic hypotension should occur, symptomatic treatment should be instituted and vital signs monitored. The patient should be placed supine with the legs elevated. If this is not sufficient, plasma volume should be increased by infusion of isotonic saline solution. Serum electrolyte and acid balance should be checked and corrected, if needed. Sympathomimetic drugs may be administered if the abovementioned measures are not sufficient.
Candesartan cannot be removed by haemodialysis. It is not known to what extent hydrochlorothiazide is removed by haemodialysis.
For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Candesartan cilexetil alone or in combination with hydrochlorothiazide showed no evidence of genotoxic potential in a series of assays for gene mutations (Salmonella typhimurium and Escherichia coli), chromosomal aberrations (mouse micronucleus assay) and DNA damage (unscheduled DNA synthesis in rat liver). In addition, candesartan cilexetil alone showed no evidence of genotoxic potential in further assays for gene mutations (mouse L5178Y cells and Chinese hamster ovary cells). The active metabolite, candesartan, caused an increase in chromosomal aberrations in vitro (Chinese hamster lung cells) but not in vivo (mouse micronucleus test and chromosomal aberrations in rat bone marrow). However, hydrochlorothiazide had mutagenic activity in a mammalian cell assay (mouse L5178Y cells) and caused an increase in chromosomal aberrations in vitro (Chinese hamster lung cells). Candesartan at subclastogenic concentration did not modify these effects of hydrochlorothiazide. Hydrochlorothiazide also had a genotoxic activity in the sister chromatid exchange assay in Chinese hamster ovary cells and a nondisjunction assay in Aspergillus nidulans.
Carcinogenicity. The carcinogenic potential of candesartan cilexetil in combination with hydrochlorothiazide has not been evaluated in animal studies.
Candesartan cilexetil alone was not carcinogenic when administered orally to mice and rats for 2 years at doses of up to 100 and 1000 mg/kg/day, corresponding to ca. 7 times and 260 times the clinical exposure at the maximum recommended daily human dose of 32 mg (based on AUC, respectively).
Hydrochlorothiazide alone was not carcinogenic in female mice in doses ca. 600 mg/kg/day, or in male and female rats at doses up to ca. 100 mg/kg/day in two year feeding studies. These doses correspond to ca. 110 times (female mice) or 40 times (male and female rats) the clinical exposure at the maximum recommended daily human dose of 25 mg (based on BSA). However, there was equivocal evidence for hepatocarcinogenicity in male mice that received ca. 600 mg/kg/day.
