Take this product by mouth as directed, usually once or twice daily. Follow all directions on the product package, or use as directed by your doctor. If you have any questions, ask your doctor or pharmacist.
Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
