Precautions

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

Using this medicine while you are pregnant (especially in your second or third trimester) 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, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash; itching; hoarseness; trouble breathing; trouble swallowing; or any swelling of your hands, face, or mouth while you are using this medicine.

Stop using this medicine and call your doctor right away if you have severe stomach pain. This could be a symptom of a condition called intestinal angioedema.

Dizziness, lightheadedness, or fainting may occur after the first dose, especially 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.

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 which may cause low blood pressure.

Check with your doctor right away if you experience dizziness, fainting, confusion, muscle pain, weakness, and/or a fast heartbeat. Use extra care if you exercise or if the weather is hot. Heavy sweating can cause dehydration (loss of too much water) or electrolyte imbalances (loss of sodium in the body).

This medicine may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests, or if you have any questions, check with your doctor.

Check with your doctor if you have any signs of fever, chills, or sore throat. These could be symptoms of an infection resulting from low white blood cells.

Stop using this medicine and check with your doctor right away if you have pain or tenderness in the upper stomach; 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.

Check with your doctor immediately if blurred vision, difficulty in reading, eye pain, or any other change in vision occurs during or after treatment. This could be a sign of a serious eye problem. Your doctor will want you to have your eyes checked by an ophthalmologist (eye doctor).

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 with 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.

This medicine may increase the amount of potassium in your blood. Do not use salt substitutes or supplements containing potassium or without first checking with your doctor.

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.

If your symptoms do not improve within a few days or if they become worse, check with your doctor.

Black patients may be less sensitive to the blood pressure-lowering effects of this medicine. In addition, the risk of a serious allergic reaction involving swelling of the face, mouth, hands, or feet may be increased.

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.
