What DILATREND is used for
DILATREND contains the active ingredient carvedilol.
DILATREND is used to treat
- heart failure
- high blood pressure, which is called hypertension
DILATREND belongs to a group of medicines called beta-blockers. These medicines work by relaxing tightened blood vessels and slowing the heart rate. DILATREND has the additional effect of being an antioxidant.
Heart Failure: Heart failure occurs when the heart can no longer pump blood strongly enough for the body's needs. Often the heart grows in size to try to improve the blood flow but this can make the heart failure worse.
Symptoms of heart failure include shortness of breath and swelling of the feet or legs due to fluid build-up.
DILATREND reduces the pressure that the heart has to pump against as well as controlling your heart rate. Over 6 months or more this will reduce the size of an oversized heart and increase its efficiency.
DILATREND reduces the chances of you being admitted to hospital and/or dying from this condition.
DILATREND is often used with other medicines to treat heart failure.
Hypertension: All people have blood pressure. This pressure helps to push blood all around your body. Your blood pressure changes during the day, depending on how busy you are or how you are feeling.
You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
Regular blood pressure checks are the only way of knowing that you have hypertension. There are usually no symptoms of hypertension and you may feel fine. If hypertension is not treated, serious health problems such as stroke, heart disease and kidney failure may occur.
DILATREND helps to lower your blood pressure.
Your doctor, however, may have prescribed DILATREND for another purpose.
Ask your doctor if you have any questions about why DILATREND has been prescribed for you.
DILATREND is not addictive.
This medicine is available only with a doctor's prescription.

How to take DILATREND
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
How much to take
Take DILATREND exactly as your doctor has prescribed.
Your doctor will tell you how many DILATREND tablets to take each day. This depends on your condition and whether or not you are taking other medicines.
The usual starting dose in heart failure is 3.125 mg twice daily. The dose is usually increased every two weeks to 6.25 mg twice daily, 12.5 mg twice daily and then 25 mg twice daily. However, this may be done more slowly if side effects occur. If the tablets slow your heart too much you may go back to a lower dose.
High Blood Pressure
Adults: The recommended dose for initiation of therapy is 12.5 mg a day for the first two days.
Thereafter, the recommended dosage is 25 mg once a day.
If necessary, the dosage may be increased every two weeks up to the recommended maximum daily dose of 50 mg given once a day or in divided doses (twice daily).
Elderly: The recommended dose for initiation of therapy is 12.5 mg once daily, which has provided satisfactory control in some patients. If the response is inadequate, the dose may be increased every two weeks up to the recommended maximum daily dose.
Your doctor will monitor you carefully each time the dose is increased.
How to take it
Swallow the tablets whole or halved with a glass of water.
Do not crush or chew the tablets.
When to take it
Take DILATREND during or immediately after a meal, 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 to remember when to take it.
If you take DILATREND on an empty stomach, it may increase the risk of some of the side effects.
How long to take it
Continue taking DILATREND until your doctor tells you to stop.
Make sure you have enough to last over weekends and holidays.
It is very important that DILATREND is not ceased suddenly. If you are to stop taking DILATREND your doctor will advise you to reduce the dose slowly over approximately two weeks.
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 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 your dose, ask your pharmacist for some hints.

If you are not sure what to do, contact your doctor or pharmacist. You may need urgent medical attention.
