Side Effects
The dosage is based on your medical condition, response to treatment, and laboratory tests. Consult your doctor or pharmacist for more details. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon.
Do not use a household spoon because you may not get the correct dose. Doing so can release all of the drug at once, increasing the risk of side effects. 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. If you are taking the chewable tablet, chew the medication thoroughly before swallowing. If you are taking the rapidly-dissolving tablets, dissolve in the mouth with or without water as directed by your doctor or the product package.
Avoid taking large doses of vitamin C within one hour before or after taking this product.
For The Consumer
Although not all of these side effects may occur, if they do occur they may need medical attention. These side effects may go away during treatment as your body adjusts to the medicine.
