cranberry

What is the most important information I should know about cranberry?

Follow all directions on the product label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

What is cranberry?

Cranberry is produced from the berry fruit of a North American evergreen shrub. Cranberry is acidic and can interfere with unwanted bacteria in the urinary tract. Cranberry is also believed to act as a diuretic ("water pill").

Cranberry (as juice or in capsules) has been used in alternative medicine as a possibly effective aid in preventing symptoms such as pain or burning with urination. Cranberry will not treat the bacteria that causes a bladder infection.

Other uses not proven with research have included: urination problems caused by an enlarged prostate; reducing urine odor to improve quality of life in people with urinary incontinence; or healing the skin around the opening of a urostomy (a surgical opening formed to direct urine away from the bladder).

Cranberry is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Cranberry may also be used for purposes not listed in this product guide.

How should I take cranberry?

When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.

The chewable tablet must be chewed before you swallow it.

Do not use different forms (juice, tablets, capsules, etc) of cranberry at the same time without medical advice. Using different formulations together increases the risk of an overdose.

What happens if I miss a dose?

Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra cranberry to make up the missed dose.
