Before using this medication, tell your doctor if you have congestive heart failure, kidney or liver disease, cirrhosis, bronchospastic lung disease, a thyroid disorder, gout, lupus, diabetes, or if you are allergic to sulfa drugs.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
