Bisoprolol

High blood pressure, angina, and heart failure are serious cardiovascular conditions that require consistent long-term management. Bisoprolol tablets are a prescription cardioselective beta blocker used to treat hypertension, angina pectoris, and stable chronic heart failure in adults. Bisoprolol is one of the most widely prescribed beta blockers in the United Kingdom and is particularly well established in the management of heart failure, where it is a cornerstone of guideline-directed medical therapy. It is taken once daily and is available in a range of strengths to support careful dose titration. A prescription can only be issued following a clinical consultation with a registered prescriber.

Bisoprolol tablets are an oral prescription medicine containing bisoprolol fumarate as the active ingredient. Bisoprolol belongs to the beta adrenoceptor blocking agent class of medicines, commonly referred to as beta blockers. It is a highly cardioselective beta blocker, meaning it acts preferentially on beta-1 receptors found predominantly in the heart, with relatively little effect on beta-2 receptors found in the airways and blood vessels. This high degree of cardioselectivity makes bisoprolol a preferred choice in patients who require a beta blocker but have respiratory considerations.

Bisoprolol is licensed in the United Kingdom for three indications: treatment of hypertension (high blood pressure), management of stable angina pectoris, and treatment of stable chronic heart failure with reduced ejection fraction. It is available in six strengths: 1.25mg, 2.5mg, 3.75mg, 5mg, 7.5mg, and 10mg tablets. The wide range of strengths reflects the need for careful dose titration, particularly in heart failure, where treatment is started at a very low dose and increased gradually under clinical supervision.

All clinical information on this page is drawn from the current UK Summary of Product Characteristics for bisoprolol fumarate tablets.

Important: Do not stop taking bisoprolol suddenly without speaking to your prescriber first. Abrupt withdrawal of a beta blocker can cause a rebound increase in heart rate and blood pressure, and may trigger or worsen angina or cause serious cardiac events. In patients with heart failure, sudden withdrawal can lead to a significant deterioration in cardiac function. Your prescriber will advise on how to reduce your dose gradually if treatment needs to be stopped.

Bisoprolol works by selectively blocking beta-1 adrenoceptors in the heart. These receptors are normally stimulated by adrenaline and noradrenaline, hormones that increase heart rate and the force of cardiac contraction. By blocking these receptors, bisoprolol reduces heart rate and lowers the force with which the heart beats.

Effect on Blood Pressure

The reduction in heart rate and cardiac output lowers the pressure at which blood is pumped through the arteries, reducing both systolic and diastolic blood pressure. Bisoprolol provides a sustained antihypertensive effect with once-daily dosing. It is used alone or as part of a combination antihypertensive regimen, often alongside a calcium channel blocker, ACE inhibitor, or diuretic.

Effect on Angina

In angina, the reduced heart rate and lower force of cardiac contraction decrease the oxygen demand of the heart muscle. This reduces the frequency and severity of angina episodes, particularly those triggered by physical activity or emotional stress. Many patients experience an improvement in exercise tolerance with regular bisoprolol treatment.

Effect on Heart Failure

In stable chronic heart failure, the sustained activation of the sympathetic nervous system contributes to progressive deterioration of cardiac function. By blocking this activation at the heart, bisoprolol reduces the harmful long-term effects of adrenaline on cardiac muscle. Clinical evidence supports that bisoprolol reduces mortality and hospitalisation in patients with stable chronic heart failure with reduced ejection fraction. Treatment must be started at a very low dose (1.25mg) and increased slowly under close clinical supervision.

Always take bisoprolol exactly as your prescriber instructs. The information below summarises key points from the current UK SmPC. Read the Patient Information Leaflet supplied with your medicine before starting treatment.

• Take bisoprolol once daily, in the morning.
• Swallow the tablet whole with a glass of water. Bisoprolol tablets are scored and may be halved if your prescriber instructs you to do so, but do not crush or chew them.
• Bisoprolol can be taken with or without food.
• Take bisoprolol at the same time each day. Consistent timing helps maintain a steady level of the medicine in your body.
• If you miss a dose, take it as soon as you remember, provided there are more than twelve hours before your next scheduled dose. If fewer than twelve hours remain, skip the missed dose and continue with your normal schedule. Do not take two doses on the same day.
• Never stop taking bisoprolol suddenly without medical advice. Abrupt withdrawal can cause a significant worsening of your condition. Your prescriber will advise on a gradual dose reduction if treatment needs to be stopped.

Bisoprolol tablets are available in six strengths through this service. The wide range of strengths reflects the need for careful dose titration, particularly in heart failure. Your prescriber will determine the appropriate starting dose and any subsequent adjustments based on the condition being treated, your heart rate, blood pressure, and clinical response.

Bisoprolol 1.25mg Tablets

The 1.25mg tablet is the starting dose for patients with stable chronic heart failure. Heart failure treatment with bisoprolol must begin at this very low dose and be increased slowly, typically doubling every two weeks, only if the previous dose is well tolerated. This cautious titration is essential in heart failure because the heart is fragile and sudden changes in beta blockade can cause deterioration. This strength is not typically used for hypertension or angina.

Bisoprolol 2.5mg Tablets

The 2.5mg tablet is used as an early titration step in heart failure, and may also be used as a starting dose for hypertension or angina in patients who are more sensitive to beta blockade, such as older adults or those with lower baseline heart rates. Your prescriber will advise whether this strength is appropriate for your circumstances.

Bisoprolol 3.75mg Tablets

The 3.75mg tablet is an intermediate titration strength used primarily in heart failure dose escalation. It corresponds to the step between 2.5mg and 5mg in the titration schedule. This strength may also be used to find the optimal dose for patients with hypertension or angina who experience side effects at 5mg but require more than 2.5mg for adequate symptom control.

Bisoprolol 5mg Tablets

The 5mg tablet is a commonly used maintenance dose for hypertension and angina in adults. It is also a key titration step in heart failure dose escalation. For hypertension, 5mg once daily provides effective blood pressure control in many patients. For angina, 5mg once daily is a standard starting dose with the option to increase if symptoms remain inadequately controlled.

Bisoprolol 7.5mg Tablets

The 7.5mg tablet is used as an intermediate step in heart failure titration and as a dose adjustment strength for hypertension or angina where 5mg is insufficient but 10mg is not yet tolerated. This strength reflects the clinical need for flexibility in finding the optimal dose for individual patients.

Bisoprolol 10mg Tablets

The 10mg tablet is the maximum licensed dose for hypertension and angina. It is also used as a maintenance dose in heart failure, where the target dose is 10mg once daily, achieved through gradual titration. Doses above 10mg daily are not recommended. All dose decisions are made by your prescriber. Do not adjust your dose without medical advice.

Like all medicines, bisoprolol can cause side effects, although not everyone experiences them. The information below is based on the current UK SmPC. Refer to the Patient Information Leaflet for the full list.

Common Side Effects (may affect up to 1 in 10 people)

• Bradycardia (a slow heart rate) - bisoprolol reduces heart rate as part of its therapeutic mechanism. If the heart rate falls excessively this may require a dose review.
• Cold or numb hands and feet, caused by reduced blood flow to the extremities.
• Fatigue and tiredness, particularly at the start of treatment or after a dose increase.
• Dizziness or lightheadedness, particularly when standing up quickly.
• Gastrointestinal effects such as nausea, vomiting, diarrhoea, or constipation.
• Headache.

Uncommon Side Effects (may affect up to 1 in 100 people)

• Sleep disturbance, including difficulty sleeping, vivid dreams, or nightmares.
• Low mood, depression, or mood changes.
• Dry eyes or visual disturbances.
• Skin rash or itching.
• Worsening of symptoms of peripheral artery disease such as leg cramps on walking.

Serious Side Effects: Seek Urgent Medical Attention

Contact your prescriber or go to your nearest accident and emergency department promptly if you experience any of the following:

• A very slow or significantly irregular heartbeat, or a sudden worsening of breathlessness.
• Worsening breathlessness or wheeze, particularly if you have a respiratory condition - bisoprolol may occasionally worsen bronchospasm even at low doses in susceptible individuals.
• Signs of worsening heart failure such as increasing breathlessness at rest, rapid weight gain due to fluid retention, or significant swelling of the ankles or legs.
• Signs of a serious allergic reaction such as sudden swelling of the face, lips, tongue, or throat, difficulty breathing, or a severe skin reaction.
• Worsening of circulation problems in the legs or feet, such as severe pain on walking or changes in skin colour.

Report any suspected side effect to your prescriber, pharmacist, or via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk.

Bisoprolol Tablets May Be Suitable If You:

• Are an adult with hypertension, angina, or stable chronic heart failure with reduced ejection fraction and have been assessed as requiring beta blocker therapy.
• Are already prescribed bisoprolol and require a repeat prescription through an online prescribing service.
• Have heart failure and are under ongoing clinical supervision, with monitoring in place to support dose titration.

Bisoprolol Tablets Are Not Suitable If You:

• Have asthma or a history of bronchospasm - bisoprolol is contraindicated in patients with asthma.
• Have acute decompensated heart failure requiring intravenous inotropic therapy.
• Have second or third degree heart block (unless you have a functioning pacemaker).
• Have sick sinus syndrome or sinoatrial block.
• Have severe bradycardia (resting heart rate below 60 beats per minute before starting treatment).
• Have cardiogenic shock.
• Have severe peripheral artery disease or severe Raynaud's phenomenon.
• Have untreated phaeochromocytoma.
• Have metabolic acidosis.
• Have a known allergy or hypersensitivity to bisoprolol or any excipient listed in the SmPC.
• Are under 18 years of age (this service is for adults only).

Cautions

Bisoprolol should be used with caution in patients with chronic obstructive pulmonary disease (COPD) or mild asthma, as even highly cardioselective beta blockers can worsen airway obstruction in some patients. Caution is also required in patients with first degree heart block, diabetes mellitus (bisoprolol can mask some symptoms of hypoglycaemia including palpitations), prinzmetal angina, and mild to moderate peripheral artery disease. Patients with psoriasis should be aware that beta blockers may worsen this condition. Your prescriber will take all relevant medical history into account during your consultation.

Important Drug Interactions

Bisoprolol can interact with a number of commonly prescribed medicines. Tell your prescriber about all medicines you take, including over-the-counter products and herbal supplements. The following interactions are of particular clinical importance:

• Calcium channel blockers of the verapamil or diltiazem type: combining these with bisoprolol can cause a significant and potentially dangerous slowing of the heart rate and a marked reduction in blood pressure. This combination is generally contraindicated unless under close specialist supervision.
• Antiarrhythmic medicines such as amiodarone, flecainide, or disopyramide: concurrent use may increase the risk of bradycardia, atrioventricular block, and myocardial depression.
• Other antihypertensive medicines: the blood pressure lowering effect of bisoprolol may be enhanced when taken with other antihypertensive agents.
• Clonidine: if both bisoprolol and clonidine are to be stopped, bisoprolol should be withdrawn several days before clonidine, to avoid a rebound rise in blood pressure.
• NSAIDs such as ibuprofen: these can reduce the antihypertensive effect of bisoprolol.
• Insulin and oral antidiabetic medicines: bisoprolol may mask some warning signs of hypoglycaemia. Blood glucose monitoring is particularly important in diabetic patients taking bisoprolol.
• Anaesthetic agents: bisoprolol can interact with some anaesthetic medicines to increase the risk of bradycardia and hypotension. Inform your anaesthetist that you take bisoprolol before any surgical procedure.

This is not a complete list of interactions. Your prescriber will carry out a full clinical assessment, including a review of your current medicines, before any prescription is considered.

Bisoprolol is a Prescription Only Medicine. The clinical consultation is the essential first step. A prescription will only be issued if a registered prescriber determines, based on their individual assessment of your circumstances, that bisoprolol is clinically appropriate for you.

During your online consultation with Pharmacy Planet, a registered prescriber will review your clinical information. This includes your blood pressure readings, heart rate, cardiac history, current medicines, and relevant medical conditions including any history of asthma, COPD, diabetes, or peripheral artery disease. For patients with heart failure, the prescriber will also assess whether adequate monitoring is in place to support safe dose titration before considering whether to issue a prescription.

Not all consultations will result in a prescription being issued. The prescriber may recommend a different dose, a different medicine, or suggest that a face-to-face appointment with your GP or cardiologist is more appropriate. This process is designed to ensure your safety.

If you are already being managed for hypertension, angina, or heart failure by your GP or a hospital team, please keep them informed of all medicines you are taking, including any prescribed through online services. Safe use of bisoprolol in heart failure depends on coordinated care and regular clinical oversight.

• Store below 25°C.
• Store in the original packaging to protect from light and moisture.
• Keep out of the sight and reach of children.
• Do not use after the expiry date printed on the packaging.
• Do not dispose of medicines via household waste or wastewater. Return unused or out-of-date tablets to your pharmacist for safe disposal.

Full storage instructions are provided in the Patient Information Leaflet supplied with your medicine.
