Nebi T Tablet belongs to the group of medications called antihypertensives. It contains a combination of two medications: Telmisartan and Nebivolol, which controls blood pressure when a single medication is ineffective. It is primarly used for the treatment of hypertension. Hypertension (high blood pressure) is a medical condition in which blood exerts a force on the artery walls (blood vessels), resulting in heart disease, irregular heartbeat, and other problems. Before starting treatment, inform your doctor if you have allergies to Telmisartan or Nebivolol, a history of heart disease, diabetes, low blood pressure, Raynaud's disease, or Prinzmetal angina. Before treatment with Nebi T Tablet, let your physician know if you are experiencing any allergic reaction to Telmisartan or Nebivolol and its ingredients.
