What CAPTOPRIL Tablets are used for

CAPTOPRIL is used for treating high blood pressure (hypertension), certain heart conditions, and certain kidney conditions associated with diabetes.

These are long-term (chronic) diseases so it is important that you continue to take your CAPTOPRIL tablets every day.

CAPTOPRIL belongs to a class of drugs known as ACE inhibitors. ACE inhibitors work to lower your blood pressure to normal levels if it is too high. CAPTOPRIL also help your heart or kidneys to work better. Your doctor will tell you why you need to take CAPTOPRIL.

Never let anyone else take your medicine.

Before you take CAPTOPRIL Tablets

When you must not take CAPTOPRIL Tablets

Do not take CAPTOPRIL Tablets if:

1. You have had an allergy to captopril or any of its additives or to another ACE inhibitor

2. You are pregnant or plan to become pregnant.

3. You are breastfeeding or plan to breastfeed

4. You have taken any other 'ACE inhibitor' medicines for high blood pressure or heart failure before, which caused your face, lips, tongue, throat, hands or feet to swell up, or made it hard for you to breathe

5. The expiry date on the pack has passed. If you take this medicine after the date has passed it may have no effect at all, or worse, an entirely unexpected effect.

6. The packaging is torn or shows signs of tampering

Before you start to take CAPTOPRIL Tablets

Tell your doctor if you plan on becoming pregnant or will be breast feeding while you are using CAPTOPRIL. Tell your doctor if you have or have had any medical condition, especially the following:

  • kidney disease
  • diabetes
  • liver disease
  • systemic lupus erythematosus (SLE), scleroderma or autoimmune diseases
  • a lack of white blood cells (neutropenia)
  • a heart attack

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking CAPTOPRIL.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may be affected by CAPTOPRIL, or may affect how well it works. These include:

  • Other medicines used to treat high blood pressure
  • Medicines used to treat angina
  • Diuretics
  • Non-steroidal anti-inflammatory drugs (NSAIDs or COX-2 inhibitor), medicines used to relieve inflammation, pain, swelling and fever
  • Potassium supplements or potassium -containing salt substitutes
  • Lithium, a medicine used to treat some types of depression
  • Some medicines used to treat coughs, colds, hayfever or sinus problems
  • Some medicines to control appetite
  • Allopurinol, a medicine used to treat gout
  • Medicines which suppress your immune system, such as corticosteroids, cyclosporin or anti-cancer drugs

Tell your doctor or pharmacist if you are currently taking any NSAIDs or COX-2 medicines. Your doctor may advise a blood test to check your kidney function before you start to take CAPTOPRIL.

If you are not sure whether you are taking any of these medicines, check with your doctor or pharmacist.

How to take CAPTOPRIL Tablets

How much CAPTOPRIL to take

Your doctor will determine your dose. The dose may vary from patient to patient as it is dependent upon your condition and how you react to this medicine. Follow all directions given to you by your doctor and pharmacist carefully.

How to take CAPTOPRIL Tablets

Swallow the prescribed dose with a glass of water while sitting upright.

When to take CAPTOPRIL Tablets

Take CAPTOPRIL on an empty stomach either one hour before or two hours after food. Food can interfere with the absorption of CAPTOPRIL. Take CAPTOPRIL at the same time each day to ensure a routine is kept.

If you forget to take CAPTOPRIL Tablets

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.

Do not take a double dose to make up for the one you missed. If you are not sure what to do, ask your doctor or pharmacist.

If you take too much (overdose)

Immediately phone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to casualty department of your nearest hospital, if you think that you or someone else may have taken too many CAPTOPRIL Tablets. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Keep telephone numbers of these places/services handy.

If you take too many CAPTOPRIL Tablets you may feel light headed or dizzy.

While you are taking CAPTOPRIL Tablets

Things you must do

Tell all doctors, dentists and pharmacists who are treating you that you are taking CAPTOPRIL, especially if you are starting on new medication.

If you become pregnant while taking CAPTOPRIL, tell your doctor immediately.

You should drink plenty of water while taking CAPTOPRIL, particularly when exercising or in hot weather. If you sweat a lot or are not drinking enough water while taking CAPTOPRIL, you may feel light headed or faint. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.

If you have severe vomiting or diarrhoea while taking CAPTOPRIL, tell your doctor

If you plan to have desensitisation therapy for an allergy, tell your doctor you are taking CAPTOPRIL.

If you are required to have any urine tests tell your doctor you are taking CAPTOPRIL. CAPTOPRIL may affect the results of these tests.

Make regular visits to your doctor so he/she can monitor your progress.

Things you must not do

Do not lower the dose or stop taking CAPTOPRIL without first checking with your doctor.

Do not use CAPTOPRIL to treat any other medical conditions unless your doctor tells you to.

Do not give CAPTOPRIL to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful when you first start taking CAPTOPRIL, as getting up from a lying down or sitting position can cause dizziness, fainting and lightheadedness. Getting up slowly may help.

Be careful operating machinery or driving a car until you know how CAPTOPRIL affects you. As with other ACE inhibitors, CAPTOPRIL can cause dizziness or lightheadedness in some people

After using CAPTOPRIL Tablets


Keep CAPTOPRIL in the original package until it is time to take them. If you take the tablets out of the package they may not keep as well.

Keep CAPTOPRIL in a cool dry place where the temperature stays below 25 deg C.

Do not store CAPTOPRIL or any other medicine in the bathroom or near a sink or stove.

Do not leave CAPTOPRIL in the car or on window sills. Heat and dampness can destroy some medicines.

Keep CAPTOPRIL where children cannot reach them. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


Tell your doctor if you stop taking CAPTOPRIL or if the tablets have passed their expiry date, ask your pharmacist what to do with any leftover tablets.
