Apo-Fosinopril HCTZ

What Fosinopril HCTZ is used for

The name of your medicine is APO-Fosinopril HCTZ. It contains the active ingredients, Fosinopril sodium and Hydrochlorothiazide.

It is used to lower high blood pressure (hypertension). Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure), this means that your blood pressure stays higher than is needed, even when you are relaxed.

There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems, including stroke, heart disease and kidney failure.

How it works

These tablets contain two medicines, Fosinopril sodium and hydrochlorothiazide. Both medicines reduce blood pressure, but work in different ways.

Fosinopril sodium belongs to a group of medicines called angiotensin converting enzyme (ACE) inhibitors. It works by widening your blood vessels, reducing the pressure in the vessels (reducing 'blood pressure') and by making it easier for your heart to pump blood around your body. This helps your heart to work better by increasing the supply of oxygen to your heart.

Hydrochlorothiazide is a diuretic. It helps reduce the amount of excess fluid in the body by increasing the amount of urine produced. It also lowers high blood pressure, particularly when combined with other blood pressure reducing medicines.

Together Fosinopril and hydrochlorothiazide lower high blood pressure.

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

Your doctor may have prescribed it for another reason.

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

There is no evidence that this medicine is addictive.

This medicine may affect your ability to drive a car or operate machinery. It may make you feel dizzy or light-headed, so wait to see if it affects you before you drive a car, operate machinery, or do anything else that could be dangerous if you are not completely alert.

How to take this medicine

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

They may be different to the information in this leaflet.

If you do not understand any written instructions, ask your doctor or pharmacist for help.

How much to take

Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your age, condition and whether or not you are taking any other medicines.

For adults the usual dose is one tablet taken once a day.

How to take it

Swallow the tablet whole with a full glass of water.

When to take it

Take it at about the same time each day.

Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take it.

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

If you need to take an antacid, take it at least 2 hours before or two hours after your dose of Fosinopril HCTZ.

How long to take it for

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

It helps to control your condition but it does not cure it. Therefore you must take it every day.

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

If you forget to take it

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 it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed.

This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

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

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 for Australia) for advice, or go to the Accident and Emergency Department at the nearest hospital, if you think that you or anyone else may have taken too much Fosinopril HCTZ.

Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

While you are taking Fosinopril HCTZ

Things you must do

Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Fosinopril HCTZ.

Tell your doctor immediately if you become pregnant.

If you are about to have any blood or urine tests, tell your doctor that you are taking this medicine.

Go to your doctor regularly for a check-up.

Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.

Try not to miss any doses.

Take the medicine even when you feel well.

If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking Fosinopril HCTZ.

Tell your doctor if you have excessive vomiting or diarrhoea or you become dehydrated (light-headed, weak, dry mouth, thirsty, muscle pain or cramps, fast heart beat, passing less urine than normal).

Make sure you drink enough water during exercise and hot weather when you are taking this medicine, especially if you sweat a lot.

If you do not drink enough water your blood pressure may drop suddenly and you may dehydrate. If you experience any of the above symptoms, tell your doctor.

If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking Fosinopril HCTZ.

Having a general anaesthetic while taking this medicine may also cause your blood pressure to drop suddenly.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.

Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. Be careful the first time you take this medicine especially if you are elderly.

If you have a pre-existing kidney problem you should follow up regularly with your doctor.

Things you must not do

Do not stop taking this medicine because you begin to feel better.

Do not give this medicine to anyone else, even if their symptoms seem similar to yours.

Do not take your medicine to treat any other complaints unless your doctor or pharmacist tells you to.

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

Stopping Fosinopril HCTZ without doctor's advice may worsen your condition. Your doctor will decide when you should stop taking it.

Things to be careful of

Be careful while driving or operating machinery until you know how this medicine affects you.

As with other ACE inhibitor medicines, you may feel light-headed or dizzy when you begin to take Fosinopril HCTZ or after your dose is increased. This is because your blood pressure is dropping suddenly.

Make sure you know how you react to your medicine before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive.

If you drink alcohol, dizziness or light-headedness may be worse.

Things that would be helpful for your blood pressure

Some self-help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

  • Alcohol - your doctor may advise you to limit your alcohol intake.
  • Weight - your doctor may suggest losing some weight to help lower your blood pressure and help lessen the amount of work your heart has to do. Some people may need a dietician's help to lose weight.
  • Diet - eat a healthy low-fat diet, which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.
  • Salt - your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt in cooking or at the table.
  • Exercise - regular exercise helps to reduce blood pressure and helps to get the heart fitter, but it is important not to overdo it. Walking is good exercise, but try to find a route that is reasonably flat. Before starting any exercise, ask your doctor about the best kind of programme for you.
  • Smoking - your doctor may advise you to stop smoking or at least cut down.
