Product Details

Description

Buy Lisinopril Online from Licensed Canadian Pharmacies

Lisinopril is a well-established medication used to treat high blood pressure, certain types of heart failure, and to support recovery after a heart attack. It belongs to a family of medicines called ACE inhibitors. These help tighten blood vessels, allowing blood to flow more easily.

When blood pressure comes down, it reduces the strain on your heart, brain, and kidneys. This further lowers your long-term risk of complications like stroke, heart attack, and kidney damage. Many patients also use Lisinopril as part of their heart-failure treatment plan because it helps the heart pump more effectively and eases daily symptoms like fatigue or shortness of breath.

After a heart attack, Lisinopril can improve survival by reducing the workload on the healing heart muscle. If your health care provider has recommended this medication, you can order Lisinopril online from Canada at significantly lower prices.

Uses and Benefits

Lisinopril is used to treat:

  • High blood pressure
  • Heart failure
  • Improve survival after a heart attack

Benefits of Lisinopril

  • It relaxes the blood vessels, which further lowers blood resistance in the circulation, so the heart does not have to work as hard to pump blood.
  • Lisinopril can be used with other heart medicines to treat heart failure.
  • This medicine can be used alone or together with other blood pressure medications, like diuretics (water pills).
  • Lisinopril can also help slow the progression of kidney damage in people with high blood pressure, especially when combined with other appropriate therapies.
Dosage
Lisinopril Dosage for Hypertension

For adults:

  • Initial dose: The typical dose is 10 mg once per day for adults not taking a diuretic.
  • Maintenance dose: it is 20 mg to 40 mg once per day.
  • The adjustments will be based on blood pressure response.

For children (6 to 17 years old):

  • Initial dose: 0.07 mg per kilogram once per day (up to 5 mg total) for children with normal kidney function.
  • Titrated maximum dose: 0.61 mg per kilogram once every day or 40 mg once daily, whichever is lower.
  • The final dosage will be based on blood pressure and tolerance.
Lisinopril Dosage for Heart Failure (Systolic Heart Failure)
  • Starting dose: It is usually 5 mg once per day. It is often taken along with a diuretic and, if needed, digitalis.
  • Usual target dose: It is up to 40 mg once a day. This dose is increased gradually as tolerated.
Lisinopril Dosage After Acute Myocardial Infarction (Heart Attack)
  • Typical dose: It begins with 5 mg within 24 hours of the heart attack.
  • It is further followed by 5 mg after 24 hours.
  • It is, then followed by a dose of 10 mg once daily.
  • Lower initial dose: For example, 2.5 mg may be used if blood pressure is low or kidney function is reduced.
Usage Guide

Here’s how to take Lisinopril tablets correctly:

  • Take this medicine at the same time each day.
  • You may take it with food or without it.
  • Swallow the whole tablet with water.
  • There’s no need to crush, chew, or cut the tablets unless your prescriber advises otherwise.
How It Works

Lisinopril is an ACE inhibitor, which simply means it blocks an enzyme called angiotensin-converting enzyme. It is a part of the renin-angiotensin-aldosterone system (RAAS), a hormone system that helps control blood pressure and fluid balance.

When ACE is blocked, the body makes less angiotensin II, a substance that normally tightens (constricts) blood vessels & triggers the release of aldosterone, which causes the body to hold onto salt and water.

With less angiotensin II, blood vessels relax and dilate (widen), and the body eliminates extra salt and water. This lowers blood pressure, reduces workload on the heart, and can protect the kidneys over time.

Side Effects

Side Effects of Lisinopril

Common Lisinopril side effects may include:

  • Lightheadedness or dizziness
  • Persistent dry cough
  • Headache
  • Mild stomach upset or diarrhea
  • Low blood pressure
  • Mild increase in potassium levels

Serious side effects (rare):

  • Angioedema (a serious allergic reaction)
  • Severe low blood pressure
  • Worsening kidney function
  • Liver problems

Note: Contact your provider if you experience any serious symptoms or unusual changes.

Warnings

These are the major safety concerns with Lisinopril:

  1. Boxed warning: Lisinopril and other RAAS-acting drugs can cause severe harm or even death to an unborn baby. The medicine must be stopped immediately if pregnancy occurs.
  2. Do not use if you’ve had angioedema: It is a sudden swelling of the face, lips, tongue, or throat. Anyone who has had angioedema from an ACE inhibitor (like Lisinopril) or has hereditary/idiopathic angioedema must avoid this medicine.
  3. Avoid combining this medicine with aliskiren if you have diabetes: This combination can dangerously affect kidney function, blood pressure, and potassium levels.

Other important warnings:

  • People with kidney disease, renal artery stenosis (narrowing of the arteries supplying the kidneys), or reduced kidney blood flow need close monitoring.
  • Lisinopril can cause hyperkalemia (high potassium), especially in:
  • Older adults
  • People with diabetes
  • Those taking potassium-sparing diuretics or potassium supplements.
  • Low blood pressure (hypotension) may occur, especially when starting treatment, after dose changes, or if you’re dehydrated or taking diuretics or heart-failure medications.
  • Any new jaundice or severe abdominal symptoms require urgent medical care.
Safety Guide

While using Lisinopril, take these precautions:

  • Breastfeeding is generally not recommended.
  • Do not stop Lisinopril suddenly unless your health care provider tells you otherwise.
  • Go to every follow-up appointment for blood pressure checks and lab tests regularly. It will help in detecting kidney changes or electrolyte problems early.
  • Avoid foods that are salty or supplements that are high in potassium unless your doctor approves them.
  • Always inform every healthcare provider (including dentists and emergency staff) that you are taking Lisinopril, especially before surgery or procedures that may affect blood pressure.
  • Never share this medicine with someone else, even if they have the same condition as you.
Missed Dose

If you ever miss a dose of Lisinopril, then take it when you remember the same day. If the time is close to your next routine dose, skip the one you miss and return to your daily dosing regimen.

Do not take two doses at once or extra doses to make up for the missed tablet. If you are unsure what to do or if you miss more than just one dose, speak with your doctor for proper guidance.

Overdose

If you take more Lisinopril than prescribed, it can lead to dangerously low blood pressure, fainting, dizziness, and, in severe cases, kidney problems or even shock. Symptoms may include:

  • Extreme lightheadedness
  • Confusion
  • Very slow or fast heartbeat
  • Difficulty staying awake

If an overdose is suspected, call your local emergency number immediately and contact Poison Control at 1-800-222-1222 in the U.S. for further instructions.

Note: Do not attempt to treat yourself on your own at home, and do not wait for symptoms to worsen before seeking help.

  • Keep it in its container, tightly closed. It’s to protect the tablets from any moisture or contamination.

  • Don’t store it near sinks or bathrooms, or other areas with high heat and humidity.
