Take this medication by mouth, usually once daily or as directed. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist.
If you are taking a brand that contains vitamin C, take this medication by mouth with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise.
If you are taking chewable tablets, chew the tablet thoroughly before swallowing.
If you are taking extended-release capsules, swallow them whole. Do not crush or chew extended-release capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Swallow the whole tablet without crushing or chewing.
If you are taking a liquid product, use a medication-measuring device to carefully measure the dose. Do not use a household spoon. Some liquid products need to be shaken before each dose.
