michael oku, nbc news, los angeles. >>> there's more ahead on "nightly news" tonight as we continue a new warning about the accelerating meltdown in the arctic. later ahead of tonight's big game on nbc, we'll tour the dallas cowboys incredible new stadium. what does a billion dollars get you these days? triglycerides are still out of line? then you may not be seeing the whole picture. ask your doctor about trilipix. statin to lower bad cholesterol, along with diet, adding trilipix can lower fatty triglycerides and raise good cholesterol to help improve all three cholesterol numbers. trilipix has not been shown to prevent heart attacks or stroke more than a statin alone. trilipix is not for everyone, including people with liver, gallbladder, or severe kidney disease, or nursing women. tell your doctor about all the medicines you take and if you are pregnant or may become pregnant. blood tests are needed before and during treatment to check for liver problems. contact your doctor if you develop unexplained muscle pain or weakness, as this can be a sign of a rare but serious side effect.
