1. What Enalapril Alter is and what it is used for
Enalapril Alter contains an active substance called enalapril maleate. It belongs to a group of medicines known as angiotensin-converting enzyme (ACE) inhibitors.
Enalapril is used to:
- treat high blood pressure (hypertension),
- treat heart failure (weakening of the heart's function). It may reduce the need for hospitalization and may help some patients live longer,
- prevent signs of heart failure. These signs include: shortness of breath, fatigue after mild physical activity such as walking, and swelling of the ankles and feet.
This medicine works by widening the blood vessels. This lowers your blood pressure. The medicine usually starts to work within one hour, and the effect lasts for at least 24 hours. Some people may need several weeks of treatment before the full effect on blood pressure is seen.
2. What you need to know before taking Enalapril Alter
Do not take Enalapril Alter
- if you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6),
- if you have ever been treated for an allergic reaction to a medicine similar to this one, called an ACE inhibitor,
- if you have ever had swelling of the face, lips, mouth, tongue or throat that caused difficulty swallowing or breathing (angioedema) when the cause was unknown or hereditary,
- if you have diabetes or kidney failure and are being treated with a blood pressure-lowering medicine containing aliskiren,
- if you are more than 3 months pregnant. (It is also advisable to avoid enalapril early in pregnancy – see Pregnancy section),
- if you have taken or are currently taking sacubitril/valsartan, a medicine used to treat a type of long-term (chronic) heart failure in adults, as the risk of angioedema (rapid swelling under the skin, including in the throat area) is high.
Do not take this medicine if any of the above situations apply to you. If you are unsure, consult your doctor or pharmacist before starting this medicine.
Warnings and precautions
Talk to your doctor before taking Enalapril Alter:
-
if you have a heart condition,
-
if you have a disease affecting the blood vessels in the brain,
-
if you have blood disorders such as low or absent white blood cells (neutropenia/agranulocytosis), low platelet count (thrombocytopenia), or low red blood cell count (anemia),
-
if you have a liver problem,
-
if you have a kidney problem (including after a kidney transplant), are on a salt-free diet, are taking potassium supplements, potassium-sparing medicines, salt substitutes containing potassium, or other medicines that may increase potassium levels in the blood, such as heparin (a medicine used to prevent blood clots), medicines containing trimethoprim or cotrimoxazole, also known as trimethoprim/sulfamethoxazole (medicines used to treat infections). This may cause high potassium levels in your blood, which can be serious. Your doctor may need to adjust your enalapril dose or monitor your blood potassium levels. See also information under the heading “Other medicines and Enalapril Alter”,
-
if you are undergoing dialysis,
-
if you have had excessive vomiting or severe diarrhoea recently,
-
if you are over 70 years old,
-
if you have diabetes. You should monitor your blood for low blood glucose levels, especially during the first month of treatment. Your blood potassium levels may also be higher,
-
if you have ever had an allergic reaction with swelling of the face, lips, tongue or throat causing difficulty swallowing or breathing. Please note that black patients have a higher risk of this type of reaction to ACE inhibitors,
-
if you have low blood pressure (you may feel faint or dizzy, especially when standing up),
-
if you have vascular collagen disease (e.g. systemic lupus erythematosus, rheumatoid arthritis, or scleroderma), are being treated with medicines that suppress your immune system, are taking allopurinol or procainamide, or any combination of these,
-
if you are taking any of the following medicines, the risk of developing angioedema may increase:
-
racecadotril, a medicine used to treat diarrhoea,
-
medicines used to prevent organ transplant rejection and for cancer (e.g., temsirolimus, sirolimus, everolimus),
-
vildagliptin, a medicine used to treat diabetes.
-
if you are taking any of the following medicines used to treat high blood pressure (hypertension):
-
an angiotensin II receptor antagonist (ARA) (also known as “sartans” – for example, valsartan, telmisartan, irbesartan), particularly if you have kidney problems related to diabetes,
-
aliskiren.
Your doctor may monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.
See also information under the heading “Do not take Enalapril Alter”.
You should inform your doctor if you think you are pregnant (or could be). Enalapril is not recommended during early pregnancy and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at this stage (see Pregnancy section).
Please note that enalapril is less effective in lowering blood pressure in black patients compared to non-black patients.
If you are unsure whether any of the above situations apply to you, consult your doctor or pharmacist before starting this medicine.
If you are about to undergo a procedure
If you are about to undergo any of the following procedures, inform your doctor that you are taking enalapril:
- any surgery or if you are to receive anaesthetics (including at the dentist),
- a treatment to remove cholesterol from your blood called “LDL apheresis”,
- a desensitisation treatment to reduce the effect of an allergy to bee or wasp stings.
If any of the above situations apply to you, consult your doctor or dentist before starting the procedure.
Other medicines and Enalapril Alter
Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This is because enalapril may affect how other medicines work. Other medicines may also affect how enalapril works. Your doctor may need to adjust your dose and/or take other precautions.
In particular, inform your doctor if you are taking any of the following medicines:
- an angiotensin II receptor antagonist (ARA) or aliskiren (see also information under the headings “Do not take Enalapril Alter” and “Warnings and precautions”),
- other medicines to lower blood pressure, such as beta-blockers or water tablets (diuretics),
- potassium-containing medicines (including dietary salt substitutes), potassium-sparing diuretics, and other medicines that may increase potassium levels in the blood (e.g., trimethoprim and cotrimoxazole for bacterial infections; cyclosporine, an immunosuppressant used to prevent organ transplant rejection; and heparin, a medicine used to thin the blood to prevent clots). See also information in the section “Warnings and precautions”,
- medicines for diabetes (including oral antidiabetic medicines and insulin),
- lithium (a medicine used to treat certain types of depression),
- medicines for depression called “tricyclic antidepressants”,
- medicines for mental disorders called “antipsychotics”,
- certain cough and cold medicines and weight-reducing medicines containing a substance called “sympathomimetic medicines”,
- certain medicines for pain or arthritis, including gold therapy,
- an mTOR inhibitor (e.g., temsirolimus, sirolimus, everolimus, medicines used to treat certain types of cancer or to prevent the body’s immune system from rejecting a transplanted organ). See also information under the heading “Warnings and precautions”,
- a medicine containing a neprilysin inhibitor such as sacubitril (available in a fixed-dose combination with valsartan), racecadotril, or vildagliptina. This may increase the risk of angioedema (swelling of the face, lips, tongue or throat with difficulty swallowing or breathing). See also information in sections “Do not take Enalapril Alter” and “Warnings and precautions”,
- non-steroidal anti-inflammatory medicines, including COX-2 inhibitors (medicines that reduce inflammation and may be used to help relieve pain),
- aspirin (acetylsalicylic acid),
- medicines used to dissolve blood clots (thrombolytics),
- alcohol.
If you are unsure whether any of the above situations apply to you, consult your doctor or pharmacist before starting this medicine.
