Special warnings about Atacand HCT

Atacand HCT can cause low blood pressure, especially if you are also taking another diuretic. This may make you feel light-headed or faint, especially during the first days of therapy. If these symptoms occur, contact your doctor. Your dosage may need to be adjusted. If you actually faint, stop taking this medication until you have talked to your doctor.

If you have congestive heart failure, liver or kidney disease, lupus, gout, or diabetes Atacand HCT should be used with caution. This drug may bring out hidden diabetes. If you are already taking insulin or oral diabetes drugs, your medication may have to be adjusted. The hydrochlorothiazide component of Atacand HCT also has a tendency to increase cholesterol levels.

The hydrochlorothiazide (as mentioned above), in Atacand HCT, may be secreted by the kidney in great quantities; if you have problematic kidneys, there is a greater risk of toxic reaction to this component.

If you have bronchial asthma or a history of allergies, you may be at greater risk for an allergic reaction to this medication.

The diuretic in Atacand HCT can cause a chemical imbalance in the body, especially if dehydration has depleted your fluids. Your doctor will perform blood tests periodically to check for this imbalance. Signs include dry mouth, thirst, weakness, sluggishness, drowsiness, restlessness, confusion, seizures, muscle pain or cramps, muscle fatigue, low blood pressure, decreased urination, rapid heartbeat, nausea, and vomiting. Call your doctor if you experience any of these symptoms.

Diuretics also can cause your body to lose too much potassium. Signs of an excessively low potassium level include muscle weakness and rapid or irregular heartbeat. To boost your potassium level, your doctor may recommend eating potassium-rich foods or taking a potassium supplement. If you think you need a supplement, check with your doctor; do not start taking one on your own. Likewise, check with your doctor before using a potassium-containing salt substitute.
