Carvedilol 3.125mg Tablets contain carvedilol, a medicine that blocks both alpha and beta receptors involved in heart rate, blood vessel tone, and blood pressure. It is used to treat high blood pressure and chronic heart failure, and to support recovery after certain heart attacks. This 3.125mg strength is typically used as a starting dose for heart failure treatment.
Carvedilol 3.125mg Tablets contain the active ingredient carvedilol, which belongs to a class of medicines known as alpha and beta-blockers. Unlike some beta-blockers that act on only one receptor type, carvedilol blocks both alpha-1 and beta receptors, giving it a broader effect on the cardiovascular system.
In treatment, carvedilol helps lower blood pressure, reduce heart rate, and ease the workload on the heart. The 3.125mg strength is commonly used as the initial dose when starting treatment for chronic heart failure, allowing the body to adjust before the dose is gradually increased under medical supervision.
Carvedilol 3.125mg may be prescribed to:
Treat high blood pressure (hypertension)
Manage mild to severe chronic heart failure, usually alongside other heart failure medicines such as diuretics or ACE inhibitors
Support recovery in clinically stable patients following a heart attack, particularly where heart function has been affected
The appropriate treatment and dose should be determined by a healthcare professional based on individual health needs.
Carvedilol works by blocking the effects of certain natural substances, such as adrenaline, on the heart and blood vessels. By blocking beta receptors, it slows the heart rate and reduces the force of each heartbeat. By also blocking alpha-1 receptors, it helps relax and widen blood vessels, contributing further to lowering blood pressure.
For heart failure, treatment is generally started at this low dose and increased gradually over several weeks, as the body needs time to adjust. Effects on blood pressure and heart rate are usually noticeable within the first hour after a dose, particularly when treatment is started or the dose is increased.
Take Carvedilol exactly as prescribed by your healthcare professional.
Usually taken twice daily, generally at the same times each day
Take with food, as this may help reduce the risk of dizziness
Swallow the tablet with a drink of water
Dizziness or lightheadedness is more likely within the first hour after a dose, especially when starting treatment or after a dose increase — avoid driving or hazardous tasks during this time if affected
Do not stop or change your dose without medical advice, as stopping suddenly can worsen underlying heart conditions
If you miss a dose, take it as soon as you remember unless it is close to your next scheduled dose, in which case skip the missed dose and continue as normal. Do not take a double dose.
Before taking Carvedilol, tell your doctor or pharmacist about your full medical history and all medicines, supplements, and herbal products you currently use.
Caution may be needed if you have, or have had:
Asthma or other breathing problems, such as bronchitis or emphysema
Very slow heart rate or certain heart rhythm/conduction disorders
Liver disease
Poor circulation in the arms or legs
Diabetes, as beta-blockers may mask signs of low blood sugar
An overactive thyroid gland
Carvedilol may interact with other blood pressure or heart medicines, certain medicines affecting heart rhythm, diabetes medicines, and medicines that affect liver enzyme activity. It is important to check possible interactions with your doctor or pharmacist before starting treatment.
Limited data are available on the use of carvedilol during pregnancy, and it is generally not recommended unless considered clearly necessary by a doctor. It is also generally advised to avoid breastfeeding while taking carvedilol, as it is not known whether it passes into breast milk in humans. Recommendations may vary between countries, so speak with your doctor or pharmacist if you are pregnant, breastfeeding, think you may be pregnant, or are planning a pregnancy.
Like all medicines, Carvedilol can cause side effects, although not everyone experiences them.
Common side effects may include:
Dizziness or lightheadedness
Tiredness or weakness
Low blood pressure
Slow heart rate
Headache
Diarrhoea or nausea
Swelling of the legs or ankles
Seek prompt medical attention if you experience signs of worsening heart failure (such as increasing breathlessness, sudden weight gain, or swelling), chest pain, fainting, a very slow or irregular heartbeat, or signs of a severe allergic reaction such as swelling of the face or throat with difficulty breathing.
This is not a complete list of side effects or warnings. Please refer to the product packaging and patient information leaflet supplied with your medicine for complete information and speak with your doctor or pharmacist if you have concerns.
Store Carvedilol according to the instructions shown on the original product packaging.
Keep in the original packaging
Keep out of reach and sight of children
Do not use after the expiry date shown on the packaging
Carvedilol is typically started at 3.125mg, especially for heart failure, and gradually increased over several weeks. This low starting dose allows the rate of up-titration to be slowed if clinically indicated, such as due to low blood pressure or heart rate.
Often, yes. Carvedilol is usually up-titrated in stages under medical supervision, with the dose only raised if the current one is well tolerated.
Taking carvedilol with food slows its absorption, which can reduce dizziness or lightheadedness on standing.
Carvedilol also blocks alpha-receptors in addition to beta-receptors, giving it an added blood-vessel-relaxing effect not shared by all beta-blockers.
This is a known effect, particularly during the first weeks or after a dose increase. Standing up slowly can help; report persistent symptoms to your doctor.
No. Stopping abruptly can worsen heart-related symptoms or raise the risk of complications. Any changes should be made gradually under medical guidance.
