Bisoprolol Hemifumarate

Bisoprolol Hemifumarate is a cardioselective beta-blocker — antihypertensive, anti-anginal, heart failure therapy medicine available in Bangladesh under many brand names. Below are its uses, side effects and precautions — and every brand with its current price.

Bisoprolol Hemifumarate is prescribed for:

• Hypertension — alone or with other blood pressure medicines.
• Chronic stable angina — preventing exertional chest pain by reducing the heart's oxygen demand.
• Stable chronic heart failure — added carefully in small, slowly increased doses alongside other heart failure medicines.
• Heart rate and rhythm control — such as in atrial fibrillation or persistent fast heartbeat, as directed by a cardiologist.
• After heart attack — in selected patients to protect the heart.

Common side effects of Bisoprolol Hemifumarate are usually mild and often settle:

• Tiredness and reduced exercise tolerance — most noticeable in the first weeks.
• Slow pulse (bradycardia) — expected to a degree; report a pulse persistently below 55, dizziness or fainting.
• Cold hands and feet.
• Dizziness, headache.
• Sleep disturbance or vivid dreams.
• Stomach upset — nausea, constipation or diarrhoea.
• In heart failure, temporary worsening of breathlessness or swelling during dose increases — report promptly.
• Less commonly: low mood, reduced sexual ability, or masking of low-blood-sugar warning signs in diabetics.

Precautions with Bisoprolol Hemifumarate:

• Never stop suddenly — this is the single most important rule with beta-blockers; always taper under medical guidance.
• Asthma or COPD — tell your doctor; although cardioselective, high doses can still tighten airways.
• Diabetes — the drug can mask tremor and palpitations of hypoglycaemia; monitor sugar more closely.
• Check your pulse and blood pressure regularly; keep a record.
• Tell doctors you take a beta-blocker before any surgery or anaesthesia.
• Caution in peripheral circulation problems, psoriasis and thyroid disease — beta-blockers can hide signs of overactive thyroid.
• It may cause tiredness or dizziness at first — assess your response before driving.

Important interactions of Bisoprolol Hemifumarate:

• Verapamil and diltiazem — combined with a beta-blocker can dangerously slow the heart or weaken its pumping; generally avoided.
• Digoxin, amiodarone, clonidine — additive slowing of heart rate and conduction; careful monitoring needed (clonidine must also never be stopped abruptly alongside).
• Insulin and oral antidiabetics — hypoglycaemia warning signs may be masked.
• Other antihypertensives — additive pressure lowering.
• NSAID painkillers — may blunt blood-pressure control.
• Salbutamol-type inhalers — beta-blockers may slightly oppose their effect; tell your doctor if you use inhalers.
• Anaesthetic agents — inform the anaesthetist.

Bisoprolol Hemifumarate must not be used in:

• Severe bradycardia (very slow heart rate) or sick sinus syndrome without a pacemaker.
• Second- or third-degree heart block (without pacemaker).
• Acute or decompensated heart failure requiring intravenous treatment.
• Cardiogenic shock or marked hypotension.
• Severe asthma.
• Severe peripheral arterial disease or Raynaud's phenomenon.
• Untreated phaeochromocytoma.
• Metabolic acidosis.
• Allergy to bisoprolol or any component.

Pregnancy: Beta-blockers like Bisoprolol Hemifumarate are used in pregnancy only when the doctor judges the benefit outweighs the risk — they may reduce placental blood flow and are associated with slower fetal growth, and the newborn can show slow heart rate or low blood sugar if the drug is used near delivery. Pregnancy-preferred alternatives (such as labetalol) often replace it. Do not stop the tablet abruptly on learning of pregnancy; contact your doctor promptly for a supervised switch.

Breastfeeding: Small amounts may pass into breast milk; data are limited. Use only on medical advice, and watch the baby for unusual sleepiness, slow feeding or poor weight gain.

Store Bisoprolol Hemifumarate below 30°C in a dry place, away from direct sunlight and moisture, keeping tablets in the original blister until use. Keep out of the reach and sight of children. Do not use beyond the expiry date printed on the pack; return expired tablets to a pharmacy for safe disposal instead of discarding them in household waste.
