How to use Hydrochlorothiazide

Take this medication by mouth, usually once a day in the morning with or without food, as directed by your doctor. If you take this medication too close to bedtime, you may need to get out of bed to urinate. This medication should be taken at least 4 hours before going to bed.

The dosage is determined by your medical condition as well as your response to treatment.

To get the most out of this medication, take it on a regular basis. Take it at the same time every day to help you remember. Even if you feel fine, keep taking this medication. The majority of people with high blood pressure do not feel ill.

Take hydrochlorothiazide at least 4 hours before or at least 4 to 6 hours after taking any bile acid-binding resins (such as colestipol or cholestyramine) if you also take certain medications to lower your cholesterol.

If your condition does not improve or if it worsens, let your doctor know (for example, your blood pressure readings remain high or increase).
