💓 Diltiazem 120mg Capsule: A Complete Guide to Heart and Blood Pressure Health
🧬 Overview
Diltiazem is a calcium channel blocker (CCB) prescribed primarily to treat high blood pressure (hypertension), angina (chest pain), and certain types of arrhythmias (abnormal heart rhythms). It works by relaxing blood vessels and slowing the heart rate, which improves blood flow and reduces the heart’s workload.
The 120mg capsule is typically a sustained-release or extended-release formulation, designed for once or twice daily dosing to maintain consistent blood levels.
💊 How to Use
-
Dosage: Usually taken once or twice daily as prescribed by a doctor.
-
Administration: Swallow the capsule whole with water. Do not crush, chew, or open it.
-
Timing: Can be taken with or without food, ideally at the same time each day.
-
Missed Dose: Take as soon as you remember unless it’s close to the next dose. Do not double up.
🔬 Active Ingredient & Mechanism
-
Diltiazem Hydrochloride (120mg):
A non-dihydropyridine calcium channel blocker that works by:-
Inhibiting calcium influx into cardiac and smooth muscle cells
-
Lowering heart rate
-
Dilating arteries, which reduces blood pressure and oxygen demand
-
😊 Common Side Effects
-
Dizziness or light-headedness
-
Fatigue or weakness
-
Headache
-
Flushing (warm feeling in the face/neck)
-
Constipation
-
Nausea
These are generally mild and may resolve with continued use.
⚠️ Serious Side Effects
Seek immediate medical attention if you experience:
-
Bradycardia (very slow heart rate)
-
Severe hypotension (low blood pressure)
-
Heart failure symptoms (shortness of breath, swelling of ankles)
-
Liver dysfunction (yellowing of skin/eyes, dark urine)
-
Severe allergic reaction (rash, itching, difficulty breathing)
🧪 Monitoring & Follow-Up
Regular monitoring is essential, especially during long-term therapy or dose adjustments:
-
Blood pressure and heart rate – to ensure the drug is effectively controlling hypertension without causing bradycardia
-
ECG (electrocardiogram) – to monitor rhythm in patients with arrhythmias
-
Liver function tests (LFTs) – occasionally needed during prolonged use
-
Kidney function tests – especially in elderly or those with pre-existing conditions
⚠️ Warnings & Precautions
-
Avoid abrupt discontinuation – May cause rebound hypertension or angina
-
Not recommended in patients with:
-
Severe bradycardia
-
Heart block (unless pacemaker is present)
-
Acute heart failure
-
-
Use with caution in elderly – Increased sensitivity and risk of side effects
-
Drug interactions:
-
May increase effects of beta-blockers, digoxin, statins, and cyclosporine
-
Avoid grapefruit juice – may increase drug levels and side effects
-
-
Pregnancy and breastfeeding – Use only if clearly needed and prescribed
📝 Summary
Diltiazem 120mg capsule is a valuable medication for managing high blood pressure, angina, and arrhythmias, promoting cardiovascular health by easing the heart’s workload and enhancing blood flow. While generally safe, it must be used with caution under medical supervision, especially in patients with underlying heart conditions or those on multiple medications. Consistent use, regular monitoring, and medical follow-up are key to safe and effective treatment.
