Zestril 10mg Tablet

Zestril 10mg Tablet is a prescription antihypertensive medicine containing lisinopril, an angiotensin-converting enzyme (ACE) inhibitor from the original AstraZeneca brand. It is prescribed to treat high blood pressure (hypertension), to manage heart failure, and to improve survival following a heart attack, working by relaxing and widening blood vessels so the heart can pump blood more efficiently and blood pressure is reduced.

Because lisinopril affects blood pressure regulation and kidney function, Zestril 10mg Tablet is only supplied against a valid prescription. Customers in Malaysia can consult a doctor online through DoctorOnCall, who will review medical history, current medications, and kidney function where relevant, before issuing a prescription and dispensing the medicine under pharmacist supervision.

Lisinopril blocks the angiotensin-converting enzyme responsible for converting angiotensin I into angiotensin II, a hormone that narrows blood vessels and raises blood pressure. By inhibiting this conversion, lisinopril allows blood vessels to relax and widen, lowering blood pressure and reducing the workload on the heart, which is particularly beneficial in heart failure and after a heart attack.

Take Zestril 10mg Tablet exactly as prescribed by your doctor, usually once daily at the same time each day, with or without food. Swallow the tablet whole with a glass of water, and do not stop taking it abruptly without medical advice even if you feel well, as blood pressure control needs to be maintained continuously.

The usual maintenance dose for adults with hypertension is 10mg to 20mg once daily, adjusted by the prescribing doctor based on blood pressure response and kidney function. Do not adjust your own dose or share this medicine with another person, as the appropriate dose depends on individual factors such as other medications, kidney function, and the specific condition being treated.

Zestril 10mg Tablet is typically stable for up to 36 months from the date of manufacture when stored correctly and unopened; always check the expiry date printed on the packaging and do not use the tablets beyond this date.

Store below 30°C in a dry place away from direct light and moisture, in the original packaging until ready to use. Keep out of reach of children and pets at all times.

• Bilateral renal artery stenosis or significant kidney artery narrowing
• Hereditary or idiopathic angioedema

• Potassium-sparing diuretics, potassium supplements, or salt substitutes may cause dangerously high potassium levels when combined
• NSAIDs (such as ibuprofen or diclofenac) may reduce the blood-pressure-lowering effect and affect kidney function
• Lithium levels may rise when taken with ACE inhibitors, requiring monitoring
• Other antihypertensive medicines or diuretics may increase the blood-pressure-lowering effect
• Diabetes medications may have an enhanced blood-sugar-lowering effect

• Attend all scheduled follow-up appointments so your doctor can monitor blood pressure and kidney function
• Rise slowly from sitting or lying down to reduce dizziness, especially when starting treatment

Zestril 10mg Tablet requires ongoing medical supervision, as regular blood pressure checks and periodic kidney function and electrolyte monitoring help ensure the medicine continues to work safely and effectively over the long term. Patients should not discontinue treatment on their own, as stopping abruptly can lead to a rebound in blood pressure.
