Take this medication by mouth, with or without food, usually once a day, or as directed by your doctor. Take each dose with a full glass of liquid. 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.

Dosage is based on your medical condition, other medications you are taking, and response to treatment. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.
