Bisobrit 2.5 Tablet 15's is used to treat hypertension (high blood pressure) and angina pectoris. It contains Bisoprolol, which affects the body's response to some nerve impulses, particularly in the heart. As a result, it slows down the heart rate and makes it easier for the heart to pump blood around the body. Thereby, it helps lower the raised blood pressure and reduces the risk of having a stroke, a heart attack, other heart problems, or kidney problems in the future. It may cause side effects like tiredness, weakness, nausea, vomiting, diarrhoea, or constipation. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
