Precautions
It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.
Check with your doctor immediately if you think that you may be pregnant. Telmisartan may cause birth defects or other problems in the baby if the medicine is taken during pregnancy.
Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines, such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may increase your blood pressure.
This medicine may cause some people to become drowsy, dizzy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.
Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea and vomiting or diarrhea. These conditions may cause you to lose too much water and lead to low blood pressure.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. This is more likely to occur in the morning. Getting up slowly may help. When you get up from lying down, sit on the edge of the bed with your feet dangling for 1 or 2 minutes. Then stand up slowly. If the problem continues or gets worse, check with your doctor.
Dizziness, lightheadedness, or fainting also may occur if you exercise or if the weather is hot. Heavy sweating can cause loss of too much water and result in low blood pressure. Use extra care during exercise or hot weather.
This medicine may increase blood sugar levels and require an adjustment to dosages of diabetes medicines. Blood sugar levels should be monitored carefully. Notify your doctor of consistent changes in blood sugar levels.
