Precautions

Drug information provided by: Micromedex

It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly.

This medicine may cause a loss of potassium from your body:

  • To help prevent this, your doctor may want you to:
    • eat or drink foods that have a high potassium content (for example, orange or other citrus fruit juices), or
    • take a potassium supplement, or
    • take another medicine to help prevent the loss of the potassium in the first place.
  • It is very important to follow these directions. Also, it is important not to change your diet on your own. This is more important if you are already on a special diet (as for diabetes) or if you are taking a potassium supplement or a medicine to reduce potassium loss. Extra potassium may not be necessary and, in some cases, too much potassium could be harmful.

To prevent the loss of too much water and potassium, tell your doctor if you become sick, especially with severe or continuing nausea and vomiting or diarrhea.

Before having any kind of surgery (including dental surgery) or emergency treatment, make sure the medical doctor or dentist in charge knows that you are taking this medicine.

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.

The dizziness, lightheadedness, or fainting is also more likely to occur if you drink alcohol, stand for long periods of time, or exercise, or if the weather is hot. While you are taking this medicine, be careful to limit the amount of alcohol you drink. Also, use extra care during exercise or hot weather or if you must stand for long periods of time.

For diabetic patients:

  • This medicine may affect blood sugar levels. While you are using this medicine, be especially careful in testing for sugar in your blood or urine.

For patients taking this medicine for high blood pressure:

  • 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.
