It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. 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.

This medicine may cause serious types of allergic reactions. These reactions can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your face, arms, legs, eyes, lips, tongue, or throat while you are using this medicine.

Call your doctor right away if you have severe stomach pain (with or without nausea or vomiting). This could be a symptom of intestinal angioedema.

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 the medicine before you drive, use machines, or do other things 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. If you faint, stop using this medicine and call your doctor right away.

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 or salt and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.

Check with your doctor if you have a fever, chills, or sore throat. These may be symptoms of an infection caused by low white blood cells.

Hyperkalemia (high potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have the following symptoms: abdominal or stomach pain, confusion, difficulty breathing, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, shortness of breath, or weakness or heaviness of the legs. Do not use medicines, supplements, or salt substitutes containing potassium without first checking with your doctor.

Check with your doctor right away if you have upper stomach pain, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using this medicine several days before having surgery or medical tests.

This medicine may be less effective in black patients. Black patients also have an increased risk of swelling of the hands, arms, face, mouth, or throat.

Do not take other medicines unless they have been discussed with your doctor. This especially includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
