Q. How can I avoid the high oxalate foods my urologist warned me about?
Your urologist may recommend that you reduce or eliminate your intake of oxalate-rich foods. Foods highest in oxalate include: chocolate or cocoa, spinach, rhubarb, beets, wheat germ, black teas (not green or herbal), some tree nuts (almonds, cashews, and hazelnuts are highest in oxalate), and legumes (beans, peanuts, soybeans). These foods have been shown to increase urinary oxalate levels. Generally when these foods are avoided, the oxalate content of other foods in the diet will total about 40-50 mg per day, the amount recommended for most calcium oxalate stone formers.
Q. Is there anyone who should not take TheraLith XR?
Individuals with decreased kidney function (renal insufficiency or failure) should not take TheraLith XR. Individuals who have been instructed to follow a low potassium diet should not take TheraLith XR.
Women who are pregnant or nursing should consult their physician regarding the use of TheraLith XR. The concern with pregnant and lactating females taking TheraLith XR is the amount of magnesium in the product. Magnesium supplements are generally not recommended for pregnant and lactating women at doses greater than 350 mg per day due to the increased risk of stomach upset and diarrhea. However, TheraLith XR has been manufactured to delay the release of its active ingredients for three-to-five hours so that it is well-tolerated, and it has been certified to have passed testing for that delayed-release and disintegration, in accordance with USP Method 2040. Therefore, TheraLith XR should be well-tolerated, and thus would be safe for women to take while pregnant or nursing.
Q. How long should I take TheraLith XR?
TheraLith XR is meant to be taken on a consistent basis for optimal results. Please speak to your urologist about how long you should take TheraLith XR.
Q. What does the "XR" in TheraLith XR stand for?
Many medications and supplements use the letters XR to indicate Extended Release. TheraLith XR has been manufactured to delay the release of its active ingredients for three-to-five hours so that it is well-tolerated, and it has been certified to have passed testing for that delayed-release and disintegration, in accordance with USP Method 2040.
