How should I take hydrochlorothiazide and captopril?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use hydrochlorothiazide and captopril in larger or smaller amounts or for longer than recommended.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking hydrochlorothiazide and captopril. This can lead to very low blood pressure, electrolyte disorders, or kidney failure.
Your blood pressure will need to be checked often. Your blood and urine may also be tested if you have been vomiting or are dehydrated. Visit your doctor regularly.
