What FOSETIC 20/12.5 is used for

FOSETIC 20/12.5 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. If 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 FOSETIC 20/12.5 works

FOSETIC 20/12.5 tablets contain two medicines, fosinopril sodium and hydrochlorothiazide. Both medicines reduce blood pressure, but work 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 (fluid tablet). 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 such as ACE inhibitors.

Your doctor may have prescribed FOSETIC 20/12.5 for another reason.

Ask your doctor if you have any questions about why FOSETIC 20/12.5 has been prescribed for you.

FOSETIC 20/12.5 is not addictive. FOSETIC 20/12.5 is available only with a doctor's prescription.

The safety and effectiveness of FOSETIC 20/12.5 in children have not been established.

How to take FOSETIC 20/12.5

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information in this leaflet. Your doctor or pharmacist will tell you how many tablets you will need to take each day.

If you do not understand the instructions on the label on the pack, ask your doctor or pharmacist for help.

How much to take

FOSETIC 20/12.5 tablet is not scored and must not be broken. Since there is no lower dose (10/12.5 mg) of FOSETIC available, if a dose of fosinopril/hydrochlorothiazide 10/12.5 mg is required, an alternative product must be used.

FOSETIC 20/12.5 is usually taken at a dose of one 20/12.5 mg tablet per day. Your doctor may have prescribed a different dose for you.

When to take it

Take FOSETIC 20/12.5 at about the same time each day. Taking your tablet at about the same time each day will help you to remember when to take it. It does not matter if you take FOSETIC 20/12.5 before or after food.

If you need to take an antacid (or Questran® Lite or Colestid® Granules), take it at least 2 hours before or two hours after your dose of FOSETIC 20/12.5

How long to take it

FOSETIC 20/12.5 helps to control your condition but does not cure it. Therefore you must take FOSETIC 20/12.5 every day. Continue taking it for as long as your doctor tells you .

If you forget to take FOSETIC 20/12.5

If you forget to take one or more doses of FOSETIC 20/12.5, take your next dose at the normal time and in the normal amount.

Do not take a double dose to make up for the dose that you missed. Do not take more than your doctor has prescribed for you

If you take too much FOSETIC 20/12.5

Immediately phone your doctor or Poisons Information Centre (telephone 13 11 26), or go to the Accident and Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too much FOSETIC 20/12.5. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

While you are taking FOSETIC 20/12.5

Things you must do

Tell any other doctors, dentists and pharmacists who are treating you that you are taking FOSETIC 20/12.5.

If you are about to be started on a new medicine, tell your doctor, dentist or pharmacist that you are taking FOSETIC 20/12.5. Tell your doctor if you have excessive vomiting or diarrhoea or experience any of the following symptoms:

  • light-headed or dizzy
  • dry mouth or thirst
  • weakness, tiredness or drowsiness
  • muscle pain or cramps
  • fast heart beat
  • passing less urine than normal

If you experience these symptoms, you may be dehydrated because you are losing too much water.

This is more likely to occur when you begin to take FOSETIC 20/12.5 or if your dose is increased.

Make sure you drink enough water during exercise and hot weather when you are taking FOSETIC 20/12.5, especially if you sweat a lot. If you do not drink enough water while taking FOSETIC 20/12.5, 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 FOSETIC 20/12.5. Having a general anaesthetic while taking FOSETIC 20/12.5 may also cause your blood pressure to drop suddenly.

If you become pregnant while taking FOSETIC 20/12.5, tell your doctor immediately.

If you are about to have blood tests, tell your doctor that you are taking FOSETIC 20/12.5. FOSETIC 20/12.5 may interfere with the results of some tests.

Have your blood pressure checked when your doctor says, to make sure FOSETIC 20/12.5 is working.

Go to your doctor regularly for a check-up. Your doctor may like to do blood tests to see how FOSETIC 20/12.5 is affecting you.

Things you must not do

Do not give FOSETIC 20/12.5 to anyone else, even if they have the same condition as you.

Do not take FOSETIC 20/12.5 to treat any other complaints unless your doctor or pharmacist tells you to.

Do not stop taking FOSETIC 20/12.5, or lower the dosage, without checking with your doctor.

Things to be careful of

As with other ACE inhibitor medicines, you may feel light-headed or dizzy when you begin to take FOSETIC 20/12.5 or after your dose is increased. This is because your blood pressure is dropping 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 FOSETIC 20/12.5, especially if you are elderly.

Be careful driving or operating machinery until you know how FOSETIC 20/12.5 affects you.

As with other ACE inhibitor medicines, FOSETIC 20/12.5 may cause dizziness, or light-headedness in some people. Make sure you know how you react to FOSETIC 20/12.5 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 loose 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 program for you.
  • Smoking - your doctor may advise you to stop smoking or at least cut down.
