Manufacturers and Registration Status
Local manufacturers in Canada include AstraZeneca and Merck & Co., both of which have played crucial roles in bringing this important medication to the market. Zestril is classified as a prescription-only medication, signifying its registration status as Rx only. This means that patients need a valid prescription from a healthcare provider to obtain it. Globally, Zestril is recognized and approved by regulatory agencies like the FDA in the US and similar organizations in Europe.
OTC/Rx Classification
Understanding the classification of Zestril is critical for safe medication management. It is classified as a prescription-only medication. Patients should consult their healthcare professionals when considering Zestril, as proper medical oversight is essential to ensure safe and effective treatment. This consultation is particularly important for those with pre-existing conditions or those taking other medications that may interact adversely with lisinopril.
Dosage & Administration of Zestril
Understanding the proper Zestril dosage is crucial for safe and effective treatment. This medication, which contains lisinopril, is typically prescribed for high blood pressure and heart-related conditions. Here's a breakdown:
Condition | Adult Starting Dose | Maximum Dose |
---|---|---|
Hypertension | 10 mg once daily | 40 mg once daily |
Pediatric (≥6 years) | 2.5–5 mg once daily | 0.6 mg/kg (max 40 mg) |
Heart failure | 5 mg once daily | 40 mg once daily |
Post-myocardial infarction | 5 mg within 24 hours | 10 mg once daily |
Dosage adjustments are essential, especially for different age groups or patients with comorbidities. For elderly patients, a lower starting dose is recommended to prevent excessive drops in blood pressure. If someone has renal impairment, it’s advisable to begin with 2.5 mg daily and adjust based on kidney function. Hepatic impairment doesn't require an initial dose adjustment, but close monitoring is wise.
For hypertension, treatment is generally lifelong unless side effects arise or complications develop. Store Zestril at room temperature (15–30°C), and protect it from moisture by keeping it in its original packaging. This helps maintain the medication's potency.
Safety & Warnings for Zestril
When it comes to Zestril contraindications, it’s essential to distinguish between absolute and relative warnings. Absolute contraindications include:
- History of angioedema related to ACE inhibitors
- Pregnancy, particularly in the second and third trimesters
- Concomitant use with sacubitril/valsartan
- Allergy to lisinopril or any of its components
Relative contraindications involve caution: individuals with renal artery stenosis or severe kidney disease may require more monitoring. Side effects of Zestril can also vary.
Common side effects include:
- Persistent cough
- Dizziness or headaches
- Fatigue
- Hyperkalemia (high potassium levels)
Less common but severe side effects might involve angioedema or impaired kidney function, highlighting the need for regular monitoring. Special precautions should be taken for vulnerable populations, such as pregnant individuals or those with kidney diseases. Zestril does not carry a black box warning, yet awareness of potential risks is crucial for patient safety.

Adherence to treatment is generally high, but there are shared worries about long-term side effects and the necessity of routine monitoring. User stories highlight how important it is for patients to communicate openly with healthcare providers about their experiences, ensuring the best outcomes while using lisinopril.
