To make sure you can safely take hydrochlorothiazide, tell your doctor if you have any of these other conditions:
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

How should I take hydrochlorothiazide (Aquazide H, HydroDIURIL, Microzide)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Your blood pressure will need to be checked often. Visit your doctor regularly.
Conditions that may cause very low blood pressure include: vomiting, diarrhea, heavy sweating, heart disease, dialysis, a low salt diet, or taking diuretics (water pills). Follow your doctor's instructions about the type and amount of liquids you should drink while taking hydrochlorothiazide. Tell your doctor if you have a prolonged illness that causes diarrhea or vomiting.
Your blood and urine may both be tested if you have been vomiting or are dehydrated.
If you need medical tests, tell the doctor ahead of time that you are taking medication that contains hydrochlorothiazide. You may need to stop using the medicine for a short time.
If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
Store at room temperature away from moisture, heat, and light.
