Tenoclor 100 Tablet is a combination of two medicines used to treat hypertension (high blood pressure). It helps to control blood pressure when a single medication is not effective. It also helps to reduce chances of any future heart attack and stroke. Tenoclor 100 Tablet is taken with or without food, preferably in the morning to avoid frequent urination at night. Keep taking it for as long as advised by your doctor. Even if you feel well, do not stop this medicine on your own because 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. Follow your doctor’s advice while taking this medicine. Nausea, headache, and fatigue are some common side effects of this medicine. Consult your doctor If any of these bother you, or get worse, or do not go away. Drink plenty of fluids while taking medicine to overcome muscle weakness, dry mouth, and extreme thirst. Dizziness or headache may occur due to low blood pressure but this gets better with time. 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.
