Find Lisinopril: Price, Vendors, and Availability - in Australia

Panorama of the headic and main points

Lisinopril is an angiotensin converting enzyme inhibitor prescribed to lower blood pressure and to protect the heart and kidneys. By preventing formation of angiotensin II, it relaxes blood vessels, reduces cardiac strain and lowers systemic blood pressure. Regular treatment reduces risks associated with long term hypertension, such as stroke and heart attack, and can slow progression of kidney disease in people with diabetes who have proteinuria. Typical uses and prudent measures are summarised in the linked sections below; for guidance on supervision and monitoring see Vigilance and safeguards and for reasons not to use it see Who is not authorized to use it.

Action pathway

Lisinopril inhibits the enzyme ACE that converts angiotensin I into angiotensin II, a substance that narrows blood vessels. With less angiotensin II, arterial tone decreases and blood pressure falls. ACE inhibition also increases levels of bradykinin, which helps dilate vessels but can produce a persistent dry cough in some patients. These pharmacological effects explain both therapeutic benefits and several common adverse reactions discussed under Hidden effects.

Medical proof of

Clinicians commonly prescribe lisinopril for the following conditions. See dose information details at How to survive it.

• Treatment of essential hypertension in adults and in selected children aged 6 years and older under specialist care.
• Heart failure management as an add-on to diuretics and other heart failure therapies to improve symptoms and outcomes.
• Secondary prevention after certain myocardial infarctions when the patient is clinically stable.
• Renal protection for people with diabetes who have albuminuria or proteinuria, to slow chronic kidney disease progression.

It may be used alone or combined with other antihypertensives depending on the clinical scenario.

Active ingredient of the formulation alongside its available forms

The active moiety is lisinopril. In Australia it is most often supplied as oral tablets in a range of strengths.

• Common tablet strengths: 2.5 mg, 5 mg and 10 mg. Many brands also provide 20 mg and 40 mg formulations.
• Liquid formulations are not routinely marketed but can be compounded by specialist pharmacies when clinically required, for example for young children or people with swallowing difficulties.
• Branded and generic products are available; names such as Zestril and plain generic lisinopril have been used in the past.

Always confirm tablet strength on the packaging and follow the dosage regimen instructions from your prescriber or pharmacist. For handling instructions see Storage systems.

How to handle it

Take lisinopril once each day, at about the same time, with water. Food does not usually affect absorption. Dose selection depends on the reason for treatment, renal function and co-prescribed medicines.

• Typical maintenance: many adults are stabilised on 5 mg to 20 mg once daily, titrated to reach target blood pressure and tolerability.
• Starting doses: where diuretics or volume depletion exist, initial doses may be low such as 2.5 mg once daily to reduce first dose hypotension risk.
• Maximum: daily doses up to 80 mg have been used, although most patients respond at lower amounts.

Paediatric dosing for children aged 6 years and older is calculated by weight and supervised by a paediatrician. Avoid stopping abruptly without professional medical advice. If you experience fainting or worsening dizziness after a dose change, seek medical review and consult Continuous observation and safety measures.

Monitoring and evaluation and precautionary guidelines

Regular follow up is important when starting lisinopril or changing the dose. Initial and repeat tests help detect kidney effects and electrolyte disturbances.

• Blood pressure checks soon after initiation and after dose adjustments.
• Biochemistry tests: serum creatinine, urea and electrolytes (especially potassium) within 1 to 2 weeks of starting or altering dose, then periodically.
• Avoid potassium supplements and high potassium salt substitutes unless a clinician prescribes them, since lisinopril can raise serum potassium.
• Be cautious with dehydration, vomiting, diarrhoea or aggressive diuretics as these can precipitate significant low blood pressure.
• If undergoing surgery or general anaesthesia tell the team you take an ACE inhibitor, because combined effects can reduce blood pressure during procedures.
• Stop the medicine and seek urgent care for sudden swelling of the face, lips, tongue or throat which may indicate angioedema.
• Pregnancy: lisinopril is contraindicated in pregnancy. If pregnancy is confirmed or planned, discontinue immediately and consult a doctor. Breastfeeding should be discussed with your clinician as other course options may be preferred.

Who should not be employing lisinopril

There are clear conditions that rule out this therapy and situations where specialist oversight is needed.

• Prior angioedema related to any ACE inhibitor, or a family history of hereditary angioedema.
• Known hypersensitivity to lisinopril or any excipient in the tablet.
• Pregnancy is an absolute contraindication because of risk to the fetus.
• Concurrent use of aliskiren in people with diabetes is not recommended due to higher risk of adverse outcomes.

Severe renal artery stenosis, advanced renal impairment or other complex medical conditions may require specialist decisions before the start. Discuss your full history and all medicines with your prescriber and examine the data Reciprocal the act of interactions create context for decisions. for potential problems.

Likely minor side effects

Many patients show good tolerance to lisinopril. Probable adverse effects range from mild and transient to rare but serious; seek urgent care for severe signs.

• Common: persistent dry cough, light headedness, fatigue, episodic headache, nausea, constipation or diarrhoea.
• Less prevalent in use: low blood pressure especially after the first dose, skin rash, changes in taste.
• Laboratory abnormalities: increases in serum potassium and creatinine occur in some patients and are monitored.
• Serious but rare: angioedema presenting as swelling of face, tongue or throat, major allergic reactions, marked hypotension, or severe skin reactions. Emergency care is required for these events.

If adverse reactions limit your quality of life, your clinician can consider dose adjustment or switching to an a secondary option agent. See Holistic medicine and similar pharmaceuticals concerning options.

Drug communication in action guidance

Review all prescription and over the counter medicines and supplements with your pharmacist or doctor. The following are notable interactions across departments improve alignment..

• Neprilysin inhibitors such as sacubitril-valsartan: increased risk of angioedema. A 36 hour washout period is recommended when changing between these classes.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can reduce the blood pressure effect and increase renal risk, particularly in older adults or the dehydrated.
• Potassium raising therapies including potassium supplements, potassium sparing diuretics like spironolactone, and salt substitutes can cause hyperkalaemia.
• Dual blockade of the renin angiotensin system with ARBs or aliskiren is generally avoided because of higher adverse event rates unless specialist supervised.
• Lithium: ACE inhibitors can increase lithium levels and risk of toxicity; monitor levels or avoid combination.
• Trimethoprim and trimethoprim-sulfamethoxazole can increase risk of high potassium when combined with ACE inhibitors.
• An ethanol-based beverage and other antihypertensives can increase dizziness or fainting risk.

Make sure to check everything. with a healthcare professional before starting new medicines. For safety checks and observation and tracking see Oversight and hazard controls.

Dose not administered

Should you forget a tablet, take it when you recall, unless the next dose is due soon. If it is nearly time for the next scheduled dose, skip the missed tablet and continue the usual dosing. Do not use extra doses to replace a i failed to take a dose.

Overdose scenario

In the event of a suspected experiencing an overdose, seek immediate medical assistance. Symptoms of experiencing an overdose may include profound dizziness, fainting or very low blood pressure. In Australia contact the Poisons Information Centre on 13 11 26 for urgent advice or attend the nearest emergency department.

Storage media and safeguarding

• Keep tablets in their original blister or bottle until use to protect them and to retain expiry details.
• Store at typical room temperature away from excessive heat and moisture.
• Place medications in a high or locked place inaccessible to children and pets.

When travelling, carry medication in original packaging together with a copy of the prescription. Do not use after the expiration date. For general safety and for what to monitor see Active surveillance and safety measures.

Common tiered pricing in AUD

Costs vary by brand, strength, pharmacy and whether the patient is eligible for PBS subsidy. The following figures are approximate and may change.

• Private purchase: generic lisinopril for one month supply typically costs about AUD 7 to AUD 20, depending on strength and pharmacy discount pricing
• PBS: many strengths and brands of lisinopril are listed on the Pharmaceutical Benefits Scheme. Eligible patients pay the standard co-payment which is around AUD 31.60 per medicine, with concessional rates of approximately AUD 7.70. Dispensing intervals and concessions may vary.
• Comparable classes: ARBs such as losartan or valsartan tend to be slightly more expensive when bought privately, commonly AUD 10 to AUD 35 per month, but PBS listings and co-payments apply similarly if subsidised.

Check current pricing model and PBS status at your local pharmacy or via the PBS website before filling a prescription.

Herbal medicines and similar drugs

If lisinopril is unsuitable or not tolerated, clinicians often consider other classes or related agents. Choice depends on the underlying condition, side effect profile and comorbidities.

• Angiotensin receptor blockers (ARBs): losartan, valsartan, irbesartan or candesartan are commonly used when ACE inhibitor cough or angioedema occurs.
• Calcium channel blockers: amlodipine or felodipine can be effective for blood pressure control and are frequently used alone or in combination.
• Other ACE inhibitors: ramipril, perindopril or enalapril may be considered, though they have similar the mechanism that drives it and some overlapping adverse reactions.
• Thiazide and thiazide-like diuretics: hydrochlorothiazide and indapamide are often combined with ACE inhibitors for added blood pressure reduction.
• Beta blockers: metoprolol, bisoprolol or carvedilol can be important after myocardial infarction or in heart failure management.
• ARNI therapy: sacubitril-valsartan is an a second possibility in selected heart failure patients and requires specialist oversight when switching from an ACE inhibitor.
