Enalapril Maleate 2.5 mg tablets – patient leaflet, side effects, dosage

1. What Enalapril maleate tablets are and what they are used for

Enalapril maleate tablets contain an active substance called enalapril maleate. This belongs to the group of medicines called ACE inhibitors (angiotensin converting enzyme inhibitors).

Enalapril maleate tablets are used to:

• treat high blood pressure (hypertension)
• treat heart failure (weakening of heart function). It can lower the need to go to hospital and can help some patients live longer
• prevent the signs of heart failure. The signs include shortness of breath, tiredness after light physical activity such as walking, or swelling of the ankles and feet.

This medicine works by widening your blood vessels. This lowers your blood pressure. The medicine usually starts to work within an hour and the effect lasts for at least 24 hours. Some people will require several weeks of treatment until the best effect on your blood pressure is seen.

2. What you need to know before you take Enalapril maleate tablets

Do not take Enalapril maleate tablets if you:

• are allergic to enalapril maleate or any of the other ingredients of this medicine (listed in section 6)
• have ever had an allergic reaction to a type of medicine similar to this medicine called an ACE inhibitor
• have ever had swelling of your face, lips, mouth, tongue or throat which caused difficulty in swallowing or breathing (angioedema) when the reason why was not known or it was inherited
• have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren
• are more than 3 months pregnant (It is also better to avoid Enalapril maleate tablets in early pregnancy see Pregnancy section)
• 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 in an area such as the throat) is increased.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.

Warnings and precautions

Talk to your doctor or pharmacist before taking Enalapril maleate tablets if you:

• have ever experienced hypersensitivity reactions, such as skin reactions and sudden fluid accumulation in the skin and mucous membranes (e.g. in the face, arms and/or legs, lips, tongue, throat or voice box), breathing difficulties and/or itching and skin rash (so called angioedema), you should stop using enalapril at once. These symptoms can occur at any time during treatment. Appropriate measures should be taken and you should be kept under close observation until the symptoms completely disappear. If swelling affects the tongue, throat or voice box, the airways may become blocked, especially if you have ever had airway surgery. In such cases, immediate first-aid therapy should be given. If you have ever experienced angioedema during use of any other medicines, you may now be at increased risk of experiencing angioedema again. You should be aware that black patients are at increased risk of these types of reactions to ACE inhibitors
• have a heart problem
• have a condition involving the blood vessels in the brain
• have a blood problem such as low or lack of white blood cells (neutropenia/agranulocytosis), low blood platelet count (thrombocytopenia) or a decreased number of red blood cells (anaemia)
• have a liver problem
• have a kidney problem (including kidney transplantation), are on a salt-restricted diet, are taking potassium supplements, potassium-sparing agents, potassium-containing salt substitutes, or other drugs that may increase potassium in your blood (e.g., heparin [a medicine used to prevent blood clots], trimethoprim-containing products such as cotrimoxazole [medicines used to treat infections]).

See also information under the heading “Other medicines and Enalapril maleate tablets”

    • Medicines used to prevent organ transplant rejection and for cancer (e.g.,

      temsirolimus, sirolimus, everolimus)

    • Vildagliptin, a medicine used to treat diabetes

  • are taking any of the following medicines used to treat high blood pressure:

    • an angiotensin II receptor blocker (ARB) (also known as sartans - for example
