What Enalapril/HCT Sandoz 20 mg/6 mg is used for
Enalapril/HCT Sandoz 20 mg/6 mg lowers high blood pressure, which doctors call 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.
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.
Your doctor may have prescribed Enalapril/HCT Sandoz 20mg/6mg for another reason. Ask your doctor if you have any questions about why Enalapril/HCT Sandoz 20mg/6mg has been prescribed for you.
Enalapril/HCT Sandoz 20mg/6mg is not 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 Enalapril/HCT Sandoz 20mg/6mg, Enalapril Sandoz or other brands of enalapril maleate, or hydrochlorothiazide, 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; fever; swelling of the face, lips, tongue or other parts of the body; skin rash, itching or hives on the skin; muscle pain or tenderness, or joint pain.
- 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
- 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 are taking a medicine containing vildagliptin
- 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.

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.

Things you must do
Always follow your doctor's instructions carefully.

If you are about to start taking a new medicine, tell your doctor and pharmacist that you are taking Enalapril/HCT Sandoz 20 mg/6 mg.
Have your blood pressure checked when your doctor says, to make sure this medicine is working.
If you feel any light-headedness or dizziness after you take your first dose of Enalapril/HCT Sandoz 20 mg/6 mg 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 have excessive vomiting and/or diarrhoea while taking this medicine, or you have any of the following symptoms, tell your doctor:
- dry mouth, thirst
- weakness, tiredness, drowsiness
- muscle pains or cramps
- fast heart beat
- 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 this medicine, especially if you sweat a lot. If you do not drink enough water while taking it, 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 Enalapril/HCT Sandoz 20 mg/6 mg. Your blood pressure may drop suddenly.
Go to your doctor regularly for a check-up. Your doctor may occasionally do a blood test to check your potassium level in the blood and to see how your kidneys are working.
