What Exactly Is Enalapril?
Simply put, Enalapril is a prescription medicine used mainly to treat high blood pressure and heart failure. Sometimes, doctors also prescribe it after a heart attack to protect your heart from further damage.
Think of your body's blood vessels as water pipes. High blood pressure means the pressure inside those pipes is much too high. Because of this high pressure, your heart has to work much harder to pump blood through your body.
Enalapril works by relaxing and widening your blood vessels. When your blood vessels open up wider, blood flows through them much more easily. This lowers your blood pressure and takes a huge weight off your heart.
In medical terms, this medicine belongs to a group of drugs called ACE inhibitors. ACE stands for angiotensin-converting enzyme, which is a substance in your body that normally makes blood vessels narrow.
Things Your Doctor Needs to Know Before You Start
Before your doctor prescribes Enalapril, they will ask you several questions about your medical history. However, if any of the following situations apply to you, it is vital that you share this information right away.
- If you are pregnant, trying to get pregnant, or breastfeeding: This is the most important warning. Enalapril can cause severe harm or even death to an unborn baby during pregnancy. You must tell your doctor right away if you expect to have a baby.
- Past allergic reactions: Tell your doctor if you ever had an allergy to Enalapril or any other ACE inhibitor medicine like Captopril or Lisinopril. Also mention any allergies to insect stings, foods, or dyes.
- Swelling of your tongue, face, or lips: Let your doctor know if you have ever experienced a condition called angioedema, which causes sudden swelling, trouble breathing, or hoarseness.
- Kidney or liver disease: Tell your doctor if your kidneys or liver do not work properly, as your body processes medicine through these organs.
- Other medical conditions: Mention if you have heart disease, blood vessel disorders, autoimmune conditions like lupus, or bone marrow diseases.
- Special diets: Inform your doctor if you follow a strict low-salt diet or any other specific nutrition plan.
- Low blood pressure: Let your doctor know if your normal blood pressure tends to run very low.
How to Use Enalapril Correctly
- Take your medicine exactly as your doctor prescribed, following the exact dose instructions. Try to take your tablet at the same time every single day so it becomes a habit.
- You can take this medicine with or without food. However, if it upsets your stomach, taking it with a meal or a snack can help.
- Keep taking your medicine every day until your doctor tells you to stop. Never stop taking it on your own just because you feel better.
- If children are prescribed this medicine, it must only happen under the direct supervision of a pediatric specialist.
What Happens If You Take Too Much?
If you think you have taken more Enalapril than your doctor prescribed, do not panic. Call your local poison control center right away. In the US, call 1-800-222-1222. In the UK, call NHS 111. If someone collapses or has trouble breathing, call 911 (US/Canada) or 999 (UK) right away or go to the nearest emergency room.
What If You Miss a Dose?
If you forget to take your dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely. Just take your next dose at the normal time.
Never take two doses at the exact same time to make up for a missed tablet. Double dosing can cause your blood pressure to drop dangerously low.
Things to Watch Out For While Taking Enalapril
While you take Enalapril, keeping a few safety habits in mind will protect your health and keep your treatment smooth.
- Regular medical checkups: Visit your doctor for regular checkups as advised. If you check your blood pressure at home, keep a log of your readings. Ask your doctor what your target range should be and when you need to call them.
- Dizziness and sleepiness: This medicine can make you feel dizzy or sleepy, especially during the first few days. Do not drive or operate heavy machinery until you know how the medicine affects your body.
- Stand up slowly: Do not jump out of bed or stand up from a chair too fast. Older adults need to be especially careful to avoid fainting or sudden dizziness. Take your time when changing positions.
- Avoid alcohol: Drinking alcohol while taking Enalapril can make dizziness and low blood pressure much worse. It is best to avoid alcohol altogether.
- Vomiting, diarrhea, and heavy sweating: If you lose a lot of body fluids due to severe stomach bugs or extreme heat, call your doctor. Dehydration combined with this medicine can cause your blood pressure to crash.
- Salt substitutes: Do not use store-bought salt substitutes without asking your doctor first. Many of these products contain high amounts of potassium, which can be dangerous when mixed with Enalapril.
- Cold and cough medicines: Always ask your pharmacist or doctor before buying over-the-counter cold, flu, or pain medicines. Some of these products can raise your blood pressure or interact badly with your prescription.
