Outline and objectives
Lisinopril is a member of the angiotensin converting enzyme inhibitor class of medicines. It is commonly prescribed to reduce high blood pressure and to reduce strain on the heart. By blocking ACE, lisinopril promotes relaxation and dilation of blood vessels which lowers blood pressure and reduces cardiac workload. These effects can decrease the risk of stroke, heart attack, and progressive kidney damage in many patients.
Clinicians may also use lisinopril after a heart attack in stable patients and as part of the treatment plan for heart failure. It is sometimes chosen to help protect kidney function in people with diabetes.

Active agent and formats
The active chemical is lisinopril. In UK community pharmacies it is most frequently supplied as oral tablets in several strengths.
Common tablet strengths available in the UK include 2.5 mg, 5 mg and 10 mg. Availability can vary by manufacturer and pharmacy stock; other strengths may be supplied as needed.
Who is permitted to be prescribed it?
Lisinopril is appropriate for many people but not everyone. Typical manifestations include:
- Essential hypertension in adults and children aged 6 years and over.
- Adjunctive therapy for heart failure alongside diuretics and other heart medications.
- Post-acute myocardial infarction stabilisation in selected patients.
- Proteinuric kidney disease related to diabetes where an ACE inhibitor is indicated to slow progression.
How to administer lisinopril?
Take the tablet once each day, preferably at the same time. Chase it with water. Your prescriber will set the dose based on your condition, kidney function and other medicines you take.
Typical adult dosing patterns used in practice are:
- Starting dose in higher risk settings (for example heart failure or if already on a diuretic): commonly 2.take 5 mg once per day.
- The standard maintenance dose lies between 5 mg and 20 mg once daily for many patients.
- Maximum licensed doses in some cases may be up to 80 mg daily for hypertension, but such regimens are rare and require close supervision.
People with reduced kidney function, older adults, and those taking diuretics may need lower initial doses and slower increases. Paediatric dosing for children aged 6 years and above is weight based and arranged by paediatric specialists.
Active continual surveillance and protective measures
Prior to commencing and after dose changes clinicians usually check blood pressure, renal function (creatinine and urea) and serum potassium. Regular tracking and monitoring of performance helps detect unwanted rises in potassium or worsening kidney function.
- If you develop a persistent dry cough, report it to your prescriber.
- If you notice swelling of the face, lips, tongue or throat seek immediate medical attention.
- Discuss 'sick day' rules with your clinician: stop or seek advice about lisinopril if you have severe vomiting, diarrhea or dehydration that could harm your kidneys.
- Tell your surgical or dental team you take an ACE inhibitor as certain anaesthetics or procedures may lower blood pressure further.
Exclusions and Alert signals: Conditions where use is not advised
Do not start or continue lisinopril in the following situations unless advised by a specialist:
- Known allergy to lisinopril or any other ACE inhibitor.
- Pregnancy, planned pregnancy or breastfeeding. ACE inhibitors are not recommended during pregnancy.
- Previous angioedema linked to ACE inhibitors or a history of hereditary or idiopathic angioedema.
Patients with severe renal artery stenosis, very low blood pressure, or markedly elevated potassium should discuss risks with their clinician before operating.
Possible adverse consequences
Most people tolerate lisinopril well. Temporary effects may be mild and settle over time, but some require prompt attention.
- Common results: dizziness or light headedness (especially on standing), fatigue, aching head, dry cough.
- Less pervasively seen effects: low blood pressure, altered kidney function tests, raised potassium, nausea, diarrhea, skin rash, taste disturbance.
- Rare yet serious.: angioedema, severe allergic reactions, significant kidney or liver dysfunction.
If adverse events limit daily life, speak to your prescriber about switching to an an alternate possibility. See Choices and contrasts for other drug classes.
Drug interaction checks
Tell your pharmacist or doctor about all medicines, herbal products and supplements you take. Several commonly used drugs interact with lisinopril.
- Potassium supplements and salt substitutes containing potassium can cause high potassium when used with lisinopril.
- Potassium-sparing diuretics increase the risk of hyperkalaemia.
- Loop and thiazide diuretics may add to blood pressure lowering and occasionally cause low blood pressure when combined.
- Non-steroidal antiinflammatory drugs such as ibuprofen, naproxen or diclofenac can reduce the antihypertensive effect and affect renal function with concurrent ACE inhibitor use.
- Lithium levels can rise when combined with ACE inhibitors, increasing toxicity risk.
- Combining ACE inhibitors with ARBs or aliskiren is usually avoided because of higher risk of kidney injury and raised potassium.
For any change in medicinesplease verify. with a clinician or pharmacist rather than adjusting treatment on your own.
Untaken dose care instructions
If you miss taking one dose, take it as soon as you recall it, unless the next dose is approaching. When it is almost time for the next dose, skip the dose you missed. Do not take two doses at once to compensate for a a dose was missed.
Overdose incident response actions
An take too much medicine can lead to severe dizziness, fainting or dangerously low blood pressure. If you suspect an take too much medicine, seek emergency medical help or contact NHS 111 for urgent advice.
Temporary temporary storage helps stage tasks before final processing. and handling tips
- Maintain the tablets at room temperature and shield them from overheating and moisture.
- Store in the original packaging and keep out of reach of children.
- Do not use after the expiration date printed on the pack.
Alternative possibilities and comparisons
If lisinopril is not suitable, several other medicines treat the same conditions. Choice depends on side effect profile, other health problems and tangible potential online interactions connect users across distances..
- Other ACE inhibitors: ramipril, enalapril, perindopril. These may have similar benefits and some patients tolerate one agent better than another.
- Angiotensin receptor blockers (ARBs): losartan, candesartan, valsartan. Often used when an ACE inhibitor causes a persistent cough or is not tolerated.
- Other antihypertensive classes: calcium channel blockers such as amlodipine, thiazide and thiazide-like diuretics such as bendroflumethiazide or indapamide, and beta blockers where clinically indicated.
In many cases generic versions of these drugs are affordable. Discuss with your clinician which a different option to consider best suits your conditions and preferences, then review this medicines the interaction between participants concerns during the process of changing therapy.
Price reference for the UK
Actual costs vary by pharmacy, brand, tablet strength, and whether you use NHS prescription services or private supply. The following are approximate figures to help planning.
- NHS prescription charge in England is a standard amount per item (currently around 9.65 GBP per item as a typical figure but please check current rates). In Scotland, Wales and Northern Ireland eligible NHS prescriptions are usually free.
- Private dispensing of generic lisinopril for a typical 28 to 30 tablet pack often has a drug cost of about 1 to 3 GBP; added dispensing fees, private prescription fees or online consultation charges can increase the total to roughly 6 to 20 GBP depending on the supplier.
- Comparable generics such as ramipril, losartan and amlodipine commonly have similar low drug acquisition costs (around 1 to 3 GBP for a month supply), but final patient cost depends on service fees.
Ask your pharmacist for a precise quote for the exact strength and pack size you need and whether a larger prescription reduces the per tablet cost. If cost is a concern, discuss prescription options with your prescriber or local pharmacy.
