Drug information provided by: Merative, Micromedex®
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
Using this medicine while you are pregnant can harm your unborn baby, especially in your second or third trimester. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away. You may need to stop using this medicine and change to another blood pressure medicine.
Dizziness, lightheadedness, or fainting may also occur especially when you get up from a lying or sitting position or if you have been taking a diuretic (water pill). 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 not alert. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.
Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water and may lead to blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.
Check with your doctor right away if you have chest pain that is worse than usual, trouble breathing, nausea, unusual sweating, faintness, or pain in your arms, jaw, back, or neck. This medicine may worsen the symptoms of an existing heart problem.
Severe, chronic diarrhea with weight loss may develop months to years after taking this medicine. Tell your doctor right away if you have these symptoms.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
