Take this medication by mouth, usually once daily or as directed. Follow all directions on the product package, or take as directed by your doctor. Do not take more than the recommended dosage. If you have any questions, ask your doctor or pharmacist.

This medication is best taken on an empty stomach 1 hour before or 2 hours after meals. Take with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. 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 may decrease its effectiveness. Do not lie down for at least 10 minutes after taking the tablets or capsules. Consult your doctor or pharmacist for details for your particular brand.

If you are taking the delayed-release form or extended-release capsules, swallow them whole. Do not crush or chew delayed-release or extended-release products. Doing so can release all of the drug at once, increasing the risk of side effects and decreasing absorption. Also, do not split extended-release 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.

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