What are furosemide tablets?

FUROSEMIDE (Lasix®) is a diuretic. Diuretics increase the amount of urine passed, which causes the body to lose water and salt. Furosemide 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 furosemide tablets are available.

What should I watch for while taking furosemide?

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 furosemide except on your prescriber's advice.

Watch your diet while you are taking furosemide. Ask your prescriber or health care professional about both potassium and sodium intake. Furosemide can make your body lose potassium and you may need an extra supply. 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 furosemide 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.

Furosemide 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 furosemide.

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