What are hydrochlorothiazide capsules or tablets?

HYDROCHLOROTHIAZIDE (HydroDIURIL®, Esidrix®, Oretic®) is a diuretic. Diuretics increase the amount of urine passed, which causes the body to lose water and salt. Hydrochlorothiazide helps to treat high blood pressure (hypertension). It is not a cure. It also reduces the swelling and water retention caused by various medical conditions, such as heart, liver, or kidney disease. Generic hydrochlorothiazide capsules or tablets are available.

What should I watch for while taking hydrochlorothiazide?

Visit your prescriber or health care professional for regular checks on your progress. Check your blood pressure regularly. Ask your prescriber or health care professional what your blood pressure should be, and when you should contact him or her. You must not get dehydrated, ask your prescriber or health care professional how much fluid you need to drink a day. Do not stop taking hydrochlorothiazide except on your prescriber's advice.

Watch your diet while you are taking hydrochlorothiazide. Ask your prescriber or health care professional about both potassium and sodium intake. Hydrochlorothiazide can make your body lose potassium and you may need an extra supply. Too high or too low potassium can cause problems. Some foods have a high potassium content such as bananas, coconuts, dates, figs, prunes, apricots, peaches, grapefruit juice, tomato juice, and orange juice.

You may get dizzy or lightheaded. Do not drive, use machinery, or do anything that needs mental alertness until you know how hydrochlorothiazide affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can make you lightheaded, dizzy and increase confusion. Avoid or limit intake of alcoholic drinks.

Hydrochlorothiazide can make your skin more sensitive to sun or ultraviolet light. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen (at least SPF 15). Do not use sun lamps or sun tanning beds or booths.

If you are going to have surgery, tell your prescriber or health care professional that you are taking hydrochlorothiazide.

Hydrochlorothiazide can increase the amount of sugar in blood or urine. If you are a diabetic keep a close check on blood and urine sugar.
