Trubest 4mg Tablet belongs to a class of medicines known as calcium channel blockers. It is used to treat high blood pressure (hypertension) and prevent angina (heart-related chest pain). It lowers blood pressure and reduces the heart's workload, which helps prevent heart attacks and strokes. Trubest 4mg Tablet may be prescribed alone or along with other medicines. The dose depends on what you are taking it for and the severity of your condition. You can take it at any time of the day, but it is best to take it at the same time each day. It should be taken with food. Keep taking it for as long as advised by your doctor. Do not stop this medicine on your own, even if you feel well, as high blood pressure often has no symptoms. If you stop taking it, your condition may get worse. Keeping active with regular exercise, reducing your weight, and eating a healthy diet will also help control your blood pressure. The most common side effects include fatigue, edema (swelling in the feet or ankles), sleepiness, dizziness, flushing, headache, and unusual beating of the heart (palpitations). Consult your doctor if any of these bother you, or do not go away. Before taking it, let your doctor know if you have any liver or kidney problems. Pregnant or breastfeeding women should also consult their doctor for advice before taking this medicine. You also need to tell your doctor what other medicines you are taking, especially those used to treat high blood pressure or heart conditions. You should have your blood pressure checked regularly to make sure that this medicine is working properly.
