What RENITEC PLUS 20/6 is used for
RENITEC PLUS 20/6 lowers high blood pressure, which doctors call 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) when your blood pressure stays higher than is needed, even when you are calm and 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. You may feel fine and have no symptoms, but eventually hypertension can cause stroke, heart disease and kidney failure. RENITEC PLUS 20/6 helps to lower your blood pressure.
RENITEC PLUS 20/6 contains two active ingredients. One of these is enalapril maleate. It belongs to a group of medicines called Angiotensin Converting Enzyme (ACE) inhibitors. It works by widening your blood vessels. This means that blood is able to pass through them more easily and the heart doesn't have to pump as hard to move blood around the body.
The other active ingredient is hydrochlorothiazide, which is a fluid tablet or diuretic. It helps reduce the amount of fluid in the body by making your kidneys pass more water and salt.
Both of these active ingredients help to lower high blood pressure.
Your doctor may have prescribed RENITEC PLUS 20/6 for another reason. Ask your doctor if you have any questions about why RENITEC PLUS 20/6 has been prescribed for you.
RENITEC PLUS 20/6 is not addictive.
Before you take RENITEC PLUS 20/6
When you must not take it
Do not take RENITEC PLUS 20/6 if 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
If you have had an allergic reaction to an ACE inhibitor before, you may be allergic to RENITEC PLUS 20/6.
Do not take RENITEC PLUS 20/6 if you have a history of swelling of the face, lips, tongue, throat, hands or feet, for no apparent reason.
Do not take RENITEC PLUS 20/6 if:

Symptoms of an allergic reaction may include skin rash, itchiness, hives, fever, shortness of breath, swelling of the face, lips or tongue, muscle pain or tenderness, or joint pain.
- you have an allergy to any sulfur medicines or sulfonamide antibiotics

How to take it
Take your RENITEC PLUS 20/6 at about the same time each day. This is best in the morning, for example, at breakfast time.

If you forget to take it
If it is less than six hours until 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 tablet(s) as you would normally.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Things you must do
Have your blood pressure checked when your doctor says, to make sure RENITEC PLUS 20/6 is working.
If you feel any light-headedness or dizziness after you take your first dose of RENITEC PLUS 20/6 or if your dose is increased, tell your doctor immediately.
If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up.
This may be because your blood pressure is falling suddenly. 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. If this problem gets worse or continues, talk to your doctor.
If you become pregnant while taking RENITEC PLUS 20/6, tell your doctor immediately.
If you have excessive vomiting and/or diarrhoea while taking RENITEC PLUS 20/6, or you have any of the following symptoms, tell your doctor:
- dry mouth, thirst
- weakness, tiredness, drowsiness

- passing less urine than normal
You may be dehydrated because you are losing too much water. This may also drop your blood pressure too much.
Make sure you drink enough water during exercise and hot weather when you are taking RENITEC PLUS 20/6, especially if you sweat a lot.
If you do not drink enough water while taking RENITEC PLUS 20/6, you may faint or feel light-headed or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are taking RENITEC PLUS 20/6.
Your blood pressure may drop suddenly.

- Alcohol -
your doctor may advise you to limit your alcohol intake.

eat a healthy diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.

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.
