Emcor contains bisoprolol, a beta-blocker used for high blood pressure, angina and heart failure. It comes as 2.5 mg, 5 mg and 10 mg tablets. Emcor FDC combinations add amlodipine for additional blood pressure control. It is a long-term medicine that must never be stopped suddenly.
What is Emcor?
Emcor is Schedule 3 in South Africa:
| Product | Contains |
|---|---|
| Emcor 2.5 / 5 / 10 mg | Bisoprolol fumarate 2.5, 5 or 10 mg |
| Emcor 5/5 FDC | Bisoprolol 5 mg + amlodipine 5 mg |
| Emcor 5/10 FDC | Bisoprolol 5 mg + amlodipine 10 mg |
| Emcor 10/5 FDC | Bisoprolol 10 mg + amlodipine 5 mg |
| Emcor 10/10 FDC | Bisoprolol 10 mg + amlodipine 10 mg |
“FDC” means fixed-dose combination, and the first number is the bisoprolol, the second the amlodipine. Check your pack, as plain Emcor and Emcor FDC are different medicines.
Bisoprolol is a beta-blocker. Adrenaline and related hormones act on beta receptors to speed the heart and make it contract harder. Bisoprolol blocks those receptors, so the heart beats more slowly and with less force — lowering blood pressure and reducing the heart’s oxygen demand.
Bisoprolol is described as cardioselective, acting mainly on beta-1 receptors in the heart rather than beta-2 receptors in the airways. That makes it better tolerated than older non-selective beta-blockers by people with breathing problems — but selectivity is relative, not absolute, and caution in asthma still applies.
Amlodipine, in the FDC versions, is a calcium channel blocker. It relaxes and widens arteries by a completely different mechanism.
Why pair a beta-blocker with amlodipine? They work on different parts of the system — one on the heart’s output, the other on vascular resistance — so together they lower blood pressure more than either alone. There is also a practical offset: amlodipine commonly causes ankle swelling, and a beta-blocker does not add to it, while a single tablet is easier to take consistently.
What is Emcor commonly used for?
- High blood pressure (hypertension) — the most common reason.
- Angina, reducing how often chest pain occurs on exertion by lowering the heart’s workload.
- Chronic heart failure, where bisoprolol is one of a small group of beta-blockers shown to improve survival. Here it is started at a very low dose and increased slowly.
- After a heart attack, to protect the heart.
- Certain fast or irregular heart rhythms, to control heart rate.
High blood pressure has no symptoms in almost everyone who has it. You will likely feel no different on Emcor, and feeling well is not evidence you can stop.
In heart failure the approach is counter-intuitive. A beta-blocker briefly makes symptoms feel worse before it helps, which is why it is introduced at a small dose and increased gradually over weeks. Feeling slightly worse early is expected and is not a reason to stop on your own.
How Emcor fits into this medicine category
| Group | Examples | What it does |
|---|---|---|
| Beta-blockers | Bisoprolol (Emcor), carvedilol, atenolol | Slow the heart, reduce its workload |
| Calcium channel blockers | Amlodipine | Relax and widen blood vessels |
| ACE inhibitors | Enalapril, perindopril | Relax vessels; protect heart and kidneys |
| ARBs | Losartan, valsartan | Similar, without the cough |
| Thiazide diuretics | Hydrochlorothiazide (Ridaq) | Remove salt and water |
| Combination tablets | Emcor FDC, Triplixam | Two or three medicines in one |

What to check before using Emcor
Never stop a beta-blocker abruptly. This is the most important point on this page. Stopping suddenly can cause a rebound — a sharp rise in heart rate and blood pressure, worsening angina, and in people with heart disease a risk of heart attack or dangerous rhythm disturbance. If it needs to stop, a doctor reduces it gradually.
Take it at the same time each day, and keep blood pressure check appointments.
Tell your doctor or pharmacist if you:
- Have asthma or COPD. Beta-blockers can trigger bronchospasm. Bisoprolol is often used cautiously in mild disease, but this must be a considered decision.
- Have a slow heart rate or heart block.
- Have diabetes. Beta-blockers can mask the warning signs of a hypo — particularly trembling and a rapid heartbeat — leaving sweating as the main clue. Check your glucose more carefully.
- Have peripheral arterial disease or Raynaud’s, which may worsen.
- Have thyroid disease. Beta-blockers can mask overactive thyroid symptoms.
- Have kidney or liver disease.
- Are pregnant, planning pregnancy or breastfeeding.
- Take verapamil or diltiazem — combining these with a beta-blocker can dangerously slow the heart.
- Take other blood pressure medicines, insulin or diabetes tablets.
- Take simvastatin and are on an FDC version, as amlodipine raises simvastatin levels and its dose is usually capped.
- Take anti-inflammatories such as ibuprofen, which raise blood pressure and blunt these medicines.
Possible cautions and when to ask a pharmacist or doctor
Common effects are tiredness, dizziness — especially standing up quickly — cold hands and feet, slow pulse, headache, and sometimes vivid dreams or disturbed sleep. Tiredness often eases after the first weeks. With the FDC versions, ankle swelling from the amlodipine is common and dose-related.
Seek medical advice promptly if you develop:
- A very slow pulse, or fainting.
- Increasing breathlessness, or waking at night short of breath.
- Marked swelling of the ankles or sudden weight gain, which may indicate worsening heart failure.
- Wheezing or chest tightness.
- Chest pain that is new, more frequent, or occurring at rest — seek emergency care.
- Severe dizziness or repeated fainting.
- Cold, painful or discoloured fingers and toes.
- A rash, or swelling of the face, lips or tongue.
- Swollen, tender gums, an uncommon effect of amlodipine.
Stand up slowly, particularly when starting or after an increase, and take care in hot weather or after alcohol.
Contact your doctor if you become pregnant, before starting any new medicine including over-the-counter anti-inflammatories, and if tiredness or cold extremities are affecting daily life — alternatives exist.

Frequently asked questions
What are Emcor tablets used for? High blood pressure, angina, chronic heart failure, protection after a heart attack, and control of some fast heart rhythms. It contains bisoprolol, a beta-blocker.
What is Emcor 5 mg used for? A common maintenance strength for blood pressure or angina. In heart failure, treatment usually starts lower and builds up to it.
What is Emcor 2.5 mg used for? The lowest strength, often a starting dose — particularly in heart failure, where treatment is introduced gradually.
What does FDC mean? Fixed-dose combination. Emcor FDC adds amlodipine to the bisoprolol; the first number is bisoprolol, the second amlodipine.
Can I stop taking it if my blood pressure is normal? No. Normal readings usually mean the medicine is working, and stopping a beta-blocker abruptly is dangerous. Speak to your doctor.
Can I take it with asthma? Only on medical advice. Beta-blockers can cause airway narrowing; bisoprolol is more selective, but the caution still applies.
Does it affect diabetes? It can mask the early warning signs of a low blood sugar. Monitor more carefully and tell your doctor you are diabetic.
Why are my ankles swollen on the FDC version? That is the amlodipine, and it is dose-related rather than a sign of heart or kidney failure. Mention it to your doctor.
