Bislol 2.5 Tablet: Uses, Dosage, Side Effects – 2026

Bislol 2.5 is a prescription cardiovascular medication containing Bisoprolol Fumarate. It belongs to a class of drugs known as beta-blockers (specifically a cardioselective $\beta_{1}$-blocker). It works by slowing down the heart rate and making the heart more efficient at pumping blood throughout the body. Produced by Opsonin Pharma Ltd., it is a primary treatment for hypertension and heart health in Bangladesh.

What is Bislol 2.5 Used For?

Bislol 2.5 contains 2.5 mg of Bisoprolol and is prescribed for:

• Hypertension (High Blood Pressure): To lower blood pressure and reduce the risk of stroke or kidney problems.

• Angina Pectoris: Prevention of chest pain caused by reduced blood flow to the heart.

• Heart Failure: Long-term management of stable chronic heart failure (often used in combination with other medications).

• Arrhythmia: Helping to stabilize and normalize irregular heart rhythms.

Clinical studies highlight that bisoprolol has one of the highest affinities for $\beta_{1}$ receptors, meaning it targets the heart specifically with less impact on the lungs compared to older beta-blockers. For more clinical detail, see this StatPearls review on Bisoprolol.

Key Reminder: Bislol is a long-term maintenance medication. It must not be used for the emergency treatment of a hypertensive crisis (extremely high blood pressure requiring immediate ER care).

Dosage

The dosage of Bislol 2.5 must be individualized by a physician.

• Hypertension/Angina: Usually starts at 2.5 mg to 5 mg once daily.

• Heart Failure: Typically starts very low (1.25 mg) and is gradually “titrated” or increased to 2.5 mg and higher over several weeks.

• Administration: Taken once daily in the morning, with or without food. Swallow the tablet whole with a glass of water.

Common Side Effects

While generally well-tolerated, Bislol 2.5 may cause:

• Fatigue or tiredness

• Dizziness or lightheadedness (especially when starting)

• Cold hands or feet (due to reduced peripheral circulation)

• Slow heart rate (bradycardia)

• Nausea or gastrointestinal discomfort

Safety Insight: Because it slows the heart, it may reduce your capacity for intense exercise. For an updated analysis on how bisoprolol affects heart rate and exercise, refer to this Summary of Product Characteristics.

Important Warnings & Precautions

• No Sudden Stops: Never stop taking Bislol abruptly. Doing so can cause “rebound” high blood pressure, chest pain, or even a heart attack. Doses must be tapered off slowly over 1–2 weeks under a doctor’s guidance.

• Asthma/Diabetes: Use with caution if you have asthma (as it can occasionally affect the airways) or diabetes (as it may mask the symptoms of low blood sugar, like a racing heart).

• Alcohol: Limit alcohol intake, as it can enhance the blood-pressure-lowering effect, leading to fainting or severe dizziness.

• Surgery: Inform your surgeon or dentist if you are taking Bislol, as it can interact with certain anesthetics.

Price in Bangladesh (January 2026 Approximate)

• Price per Tablet: Approximately ৳7.00.
