Take this medication by mouth, usually once daily or as directed by your doctor.

This medication is best taken on an empty stomach 1 hour before or 2 hours after meals. If stomach upset occurs, you may take this medication with food. Avoid taking antacids, dairy products, tea, or coffee within 2 hours before or after this medication because they will decrease its effectiveness.

Swallow this medication with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Do not lie down for at least 10 minutes after taking this medication.

Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day.
