HOW TO USE: Take this medication by mouth with or without food with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. This medication may be taken with food or milk if stomach upset occurs. Do not take the sustained-release products more often than every 12 hours.If you are using the liquid form, use a medication measuring device or spoon to carefully measure the prescribed dose. Do not use a household spoon because you may not get the correct dose. If your liquid form is a suspension, shake the bottle well before each dose.If you are using the 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. 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 using a sustained-release liquid that contains hydrocodone polistirex, do not mix the liquid with other liquids or medications. Doing so can destroy the long action of the drug and may increase side effects.This medication may cause withdrawal reactions, especially if it has been used regularly for a long time (more than a few weeks) or in high doses. In such cases, withdrawal symptoms (such as anxiety, restlessness, sweating, shaking chills, nausea, vomiting, and diarrhea) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.Though it is very unlikely to occur, this medication can also result in abnormal drug-seeking behavior (addiction/habit forming). Do not increase your dose, take it more frequently, or use it for a longer time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted.When used for an extended time, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.Inform your doctor if your condition persists for more than 1 week, if it worsens, or if it occurs with fever, rash, or persistent headache. These may be symptoms of a serious medical problem and should be checked by a doctor.
