Enalapril tablets 20 mg What Enalapril is and what it is used for: Enalapril belongs to the class of medicines called Angiotensin converting enzyme inhibitors (ACE inhibitors). It works by causing blood vessels to relax, lowering blood pressure and increasing the supply of blood and oxygen to the heart. Enalapril is 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 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. What you need to know before you use Enalapril: Do not use Enalapril • If you are allergic (hypersensitive) to enalapril maleate, any of the other ingredients in these tablets or other ACE inhibitors • If you 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. • If you are more than 3 months pregnant. (It is also better to avoid Enalapril maleate tablets in early pregnancy) • If you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren. • If you have ever had an allergic reaction to a type of medicine similar to this medicine called an ACE inhibitor • 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 in an area such as the throat) is increased. Warnings and precautions: You should let your doctor know: • If you have a heart problem • If you have a condition involving the blood vessels in the brain • If you have a blood problem such as low or lack of white blood cells, low blood platelet count or a decreased number of red blood cells (anaemia) • If you have a kidney problem (including kidney transplantation).
