Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Enalapril/HCT Sandoz 20 mg/6 mg. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Enalapril/HCT Sandoz 20 mg/6 mg against the benefits it is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Enalapril/HCT Sandoz 20 mg/6 mg is used for

The name of your medicine is Enalapril/HCT Sandoz 20 mg/6 mg. It contains the active ingredients enalapril maleate and hydrochlorothiazide.

It is used to treat mild to moderate high blood pressure (hypertension).

Everyone has blood pressure. This pressure helps to circulate the 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. Enalapril/HCT Sandoz 20 mg/6 mg helps to lower your 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.

How Enalapril/HCT Sandoz 20 mg/6 mg works

Enalapril/HCT Sandoz 20 mg/6 mg 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.

There is no evidence that Enalapril/HCT Sandoz 20mg/6mg is addictive.

Before you take Enalapril/HCT Sandoz 20 mg/6 mg

When you must not take it

Do not take this medicine if:

  • you are allergic to the active ingredients or any of the inactive ingredients mentioned at the end of this leaflet under Product Description. Some of the symptoms of an allergic reaction may include shortness of breath; wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
  • you have an allergy to any sulfur medicines or sulfonamide antibiotics.
    One of the active ingredients in this medicine, hydrochlorothiazide, is a sulfur-containing medicine (a sulfonamide). Therefore, if you are allergic to sulfur medicines, such as some antibiotics or some tablets used to treat diabetes, you are likely to be allergic to Enalapril/HCT Sandoz 20 mg/6 mg. Check with your doctor or pharmacist if you are not sure whether you are allergic to sulfur medicines.
  • 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 this medicine.
  • you have a history of swelling of the face, lips, tongue, throat, hands or feet, for no apparent reason
  • you have renal artery stenosis, a disease of the kidney
  • you are not passing urine
  • you have diabetes and are taking a medicine called aliskiren to reduce blood pressure
  • you are taking a medicine containing a neprilysin inhibitor (e.g., sacubitril). Do not take Enalapril/HCT Sandoz 20 mg/6 mg for at least 36 hours before or after you take sacubitril/valsartan, a medicine containing a neprilysin inhibitor.
  • you are pregnant or breastfeeding. Your baby may absorb this medicine in the womb or from breast milk and therefore there is a possibility of harm to the baby.
  • it is past its expiry date or the packaging appears to have been tampered with.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Do not give Enalapril/HCT Sandoz 20mg/6mg to a child. Its safety in children has not been established.

Before you start to take it

Tell your doctor if:

  • you plan on becoming pregnant or will be breastfeeding while you are using this medicine. It should not be used during pregnancy or while breastfeeding.
  • you have or have had any medical conditions, especially the following:
    – kidney disease, or if you are undergoing dialysis
    – passing less urine than is normal
    – liver disease
    – heart problems
    – diabetes.
  • you are following a very low salt diet
  • you are taking potassium supplements, potassium-sparing agents, potassium-containing salt substitutes or other drugs that may increase serum potassium (eg. Trimethoprim-containing products)
  • you have an allergy to any other medicines, especially if they are in the same drug class as enalapril maleate or hydrochlorothiazide
  • you have had an allergy to any other substances, including foods, preservatives or dyes
  • you have recently suffered from excessive vomiting or diarrhoea
  • you suffer from low blood pressure (you may notice this as faintness or dizziness, especially when standing)
  • surgery and anaesthesia (even at the dentist office) are scheduled, as there may be a sudden fall in blood pressure associated with anaesthesia
  • you are taking a medicine containing a neprilysin inhibitor (e.g., sacubitril).
  • You have had skin cancer or if you develop a new skin lesion during the treatment. Treatment with hydrochlorothiazide, particularly long-term use with high doses, may increase the risk of some types of skins and lip cancer (non-melanoma skin cancer). Discuss with your doctor how to protect your skin from sun exposure, and avoid artificial tanning.

If you have not told your doctor about any of the above, tell them before you start taking Enalapril/HCT Sandoz 20mg/6mg tablets.

For most patients, the usual dose is one tablet a day.

Enalapril/HCT Sandoz 20 mg/6 mg helps control your high blood pressure but does not cure it. Therefore it must be taken every day. Continue taking this medicine for as long as your doctor prescribes.

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.

Do not take a double dose to make up for the dose 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 when to take your medicine, ask your pharmacist for some hints.
