Buy Prinivil (Lisinopril) Online from a Canadian Pharmacy


What Is Prinivil (Lisinopril)?

Prinivil, also known by its generic name lisinopril, is a medication commonly prescribed for high blood pressure (hypertension) and heart failure. It belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors. This drug works by loosening blood vessels, which can help to improve blood circulation. Various Prinivil dosage forms are available, with the precise dosage determined by the medical condition being treated and the patient’s response to treatment when you buy Prinivil online.

Dosage, Uses, and Storage of Prinivil

It is imperative to buy Prinivil online as a doctor prescribes and store it in a cool, dry area out of reach of moisture and sunlight. Additionally, it is paramount to take the medication regularly to ensure its effectiveness.

Dosage of Prinivil

  • The dosage of Prinivil (lisinopril) is determined by the individual’s medical state and response to treatment.
  • For hypertensive patients, the typical starting dose is 10 mg once daily, potentially increasing to 20 mg as directed by a healthcare provider.
  • Individuals with renal failure or those taking diuretics may begin with lower doses, ranging from 2.5 to 5 mg.
  • It is crucial to adhere to the doctor’s instructions regarding dosage adjustments strictly when you buy Prinivil online.


One of the primary applications of lisinopril, an ACE inhibitor medication, is to treat hypertension and heart failure. Hypertension, or abnormally high blood pressure, is a common disorder that, if neglected, can lead to life-threatening conditions such as:

  • Stroke
  • kidney failure
  • cardiac disease

Lisinopril relaxes the blood vessels, which makes it convenient for the heart to pump and reduces its effort. It is also employed to treat heart failure, a situation where the heart cannot supply enough blood for the body’s requirements. Moreover, in selected circumstances, lisinopril is useful in treating kidney disorders.

How to Store Prinivil?

  • Ensure the potency and safety of Prinivil by storing it properly.
  • Store at room temperature (68-77 degrees Fahrenheit).
  • Keep in a tightly sealed container, away from moisture, heat, and direct sunlight.
  • Ideal storage locations include cool, dry areas like a medicine cabinet or drawer.
  • Avoid storing it in areas prone to dampness or temperature fluctuations, such as bathrooms or kitchens.
  • Keep Prinivil out of reach and sight of children and pets to prevent accidental ingestion.
  • Dispose of any unused or expired tablets in accordance with local regulations or consult a pharmacist for guidance related to Prinivil price and use.

How Does Prinivil Work?

Here are the key steps in which Prinivil works:

Inhibition of ACE: ACE is an enzyme that plays a vital part in the regulation of blood pressure. It converts angiotensin I (an inactive form) into angiotensin II, a potent vasoconstrictor (a substance that narrows blood vessels). By inhibiting ACE, Prinivil reduces the production of angiotensin II.

Vasodilation: With reduced levels of angiotensin II, blood vessels relax and dilate. This dilation leads to a decrease in peripheral vascular resistance, making it convenient for blood to flow through the vessels. As a result, blood pressure is lowered.

Aldosterone Suppression: Prinivil also decreases the secretion of aldosterone, a hormone that manages salt and water balance in the body. Lower levels of aldosterone lead to reduced sodium and water retention, further helping to lower blood pressure.

Decreased Sodium Reabsorption: In the kidneys, Prinivil reduces the reabsorption of sodium. This means that more sodium is excreted in the urine, leading to a decrease in fluid volume in the bloodstream, which contributes to lower blood pressure.

Improved Cardiac Function: By reducing the afterload (the resistance the heart has to overpower to eject blood) and preload (the amount of blood returning to the heart), Prinivil eases the workload on the heart. This can be beneficial for individuals with heart failure.

Protection Against Remodeling: ACE inhibitors like Prinivil have been shown to have additional benefits in preventing adverse cardiac remodeling, a process where the heart’s structure and function change in response to various stresses.

Side Effects

Common effects of Prinivil may include:

  • Cough
  • Headache
  • Dizziness
  • lowered spirits
  • drowsiness
  • queasiness
  • stomachache
  • vomiting
  • looseness of the bowels
  • gentle pruritus or skin rash

It is important to note that not everyone will face these side effects, and some may experience different or additional ones. It is suggested to visit a healthcare practitioner  for more information and assistance managing these side effects.

Warnings and Precautions 

  1. Notify your healthcare provider of any prior allergies to lisinopril or other ACE inhibitors. Signs of allergic reactions encompass skin rash, itching, swelling, severe dizziness, or breathing difficulties.
  2. Prinivil may impact kidney function, particularly in individuals with existing kidney conditions. Routine monitoring of kidney function through blood tests may be essential.
  3. Lisinopril can lead to elevated potassium levels in the blood, especially in individuals with kidney issues or those using potassium supplements. 
  4. Especially following the initial dose, Prinivil may lead to a decrease in blood pressure. This is more likely in individuals who are dehydrated or have significant sodium or fluid imbalances.
  5. Ensure adequate fluid intake, particularly in hot weather or during exercise, to prevent dehydration. Maintain a balance of electrolytes like sodium and potassium.
  6. Prinivil can pose risks to an unborn baby if taken during pregnancy. Tell your healthcare practitioner if you are pregnant. 
  7. Disclose all medications, supplements, and Prinivil cost to your healthcare provider. Certain drugs, such as potassium-sparing diuretics or potassium supplements, may interact with Prinivil.
  8. In rare instances, ACE inhibitors like Prinivil can result in a serious allergic reaction known as angioedema. This condition is characterized by swelling in the deeper layers of the skin, typically around the eyes and lips. 
  9. If you have a scheduled surgery or will be undergoing anesthesia, inform the medical team about your Prinivil price and use, as it may interact with certain anesthetics.
  10. Prinivil may occasionally cause dizziness, especially when transitioning from sitting or lying down to standing. Exercise caution during such movements.

Interactions with Other Medication

Prinivil (lisinopril) can interact with various medications, potentially affecting their effectiveness or causing adverse effects. Here are some notable interactions:

  • Potassium Supplements or Potassium-Sparing Diuretics
  • Diuretics (Water Pills)
  • Non-steroidal anti-inflammatory Drugs (NSAIDs)
  • Lithium
  • Allopurinol
  • Gold Injections
  • Insulin and Oral Diabetes Medications
  • Blood Pressure Medications
  • Certain Heart Medications (e.g., Digoxin)
  • Immunosuppressants (such as cyclosporine)
  • Certain Antibiotics (e.g., Trimethoprim)
  • Other ACE Inhibitors or Angiotensin II Receptor Blockers (ARBs)

Other drugs that obstruct the renin-angiotensin system, such as azilsartan, olmesartan, losartan, telmisartan, and valsartan, should also be bypassed or substituted for lisinopril due to increased dangers of hypotension, hyperkalemia, and renal impairment.

Frequently Asked Questions

Can Prinivil be used during pregnancy?

Using Prinivil during pregnancy is not recommended as it can harm the unborn baby. It is imperative to discuss with a physician regarding contraception measures while taking this medication. This is particularly true since many contraceptives can also harm the developing child.
