Lercanidipine tablets for high blood pressure
Effective calcium-channel blocker for managing hypertension and preventing heart complications.
Lercanidipine is a medication specifically designed to manage high blood pressure (hypertension). As a calcium-channel blocker, it relaxes blood vessels, improving blood flow and reducing strain on the heart. This helps prevent serious complications like heart attacks and strokes, even if you feel fine.

About lercanidipine
High blood pressure often goes unnoticed, but untreated it damages arteries, the heart, kidneys, and increases risks of heart disease, stroke, heart failure, and kidney failure. Lercanidipine lowers blood pressure by blocking calcium entry into vascular smooth muscle and cardiac muscle cells, causing vasodilation without significantly affecting heart contractility.
It is typically prescribed when other antihypertensives are unsuitable or as part of combination therapy. Available in 10 mg and 20 mg tablets, it is taken once daily. Treatment is long-term to maintain blood pressure control and reduce cardiovascular risks.
Key benefits include once-daily dosing for convenience and a favorable side effect profile compared to some other calcium channel blockers, with less edema in some studies. However, it is not a cure; blood pressure must be monitored regularly.
How to take lercanidipine
Always follow your doctor’s instructions and read the patient information leaflet (PIL) provided with the tablets for full details on usage, side effects, and warnings.
- Dosage: Start with 10 mg once daily, preferably in the morning at least 15-30 minutes before breakfast. Your doctor may increase to 20 mg after 2-4 weeks if needed.
- Administration: Swallow whole with water. Do not chew or crush. Take consistently at the same time each day.
- Missed dose: Take as soon as remembered unless near next dose. Do not double up.
- Duration: Long-term unless advised otherwise. Stopping suddenly may raise blood pressure; taper if instructed.
- Special populations:
- Elderly: No dose adjustment, but start cautiously.
- Liver/kidney impairment: Use lower doses; max 20 mg with caution.
- Children: Not recommended.
Before surgery or dental work, inform your healthcare provider, as lercanidipine may interact with anesthetics.
Getting the most from your treatment
To optimize lercanidipine’s effectiveness and minimize risks:
- Avoid grapefruit juice, as it inhibits metabolism and can dangerously increase drug levels.
- Monitor blood pressure regularly at home if advised.
- Combine with lifestyle changes: healthy diet (low salt), regular exercise (30 min most days), weight management, limit alcohol, quit smoking.
- Do not use over-the-counter drugs without consulting your doctor, especially NSAIDs or decongestants that raise blood pressure.
- If dizzy, rise slowly from sitting/lying to avoid falls.
Regular check-ups ensure the dose is appropriate and monitor for side effects.
Side-effects
Most side effects are mild and short-lived, especially when starting treatment. They often resolve within days to weeks.
