Important information about Tylox

This medication can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Before taking Tylox

Do not use Tylox if you are allergic to acetaminophen (Tylenol) or oxycodone. Oxycodone may be habit-forming and should be used only by the person it was prescribed for. Tylox should never be given to another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Before using Tylox, tell your doctor if you are allergic to any drugs, or if you have:

asthma, COPD, sleep apnea, or other breathing disorders;
liver or kidney disease;
a history of head injury or brain tumor;
epilepsy or other seizure disorder;
low blood pressure;
a stomach, intestinal, or pancreas disorder;

FDA pregnancy category C. This medication may be harmful to an unborn baby, and could cause breathing problems or addiction/withdrawal symptoms in a newborn. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Tylox may pass into breast milk and could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

How should I take Tylox?

Take Tylox exactly as it was prescribed for you. Do not take it in larger amounts, or use it for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

An overdose of acetaminophen can cause serious harm to your liver. The maximum amount of acetaminophen for adults is 1 gram (1000 mg) per dose and 4 grams (4000 mg) per day. One Tylox tablet may contain up to 650 mg of acetaminophen. Know the amount of acetaminophen in the specific product you are taking.

Measure the liquid form of this medication with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.

Drink 6 to 8 full glasses of water daily to help prevent constipation while you are taking Tylox. Do not use a stool softener (laxative) without first asking your doctor. You may have withdrawal symptoms when you stop using Tylox after using it over a long period of time. Do not stop using Tylox suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.

This medication can cause you to have unusual results with certain urine tests. Tell any doctor who treats you that you are using Tylox.

If you need to have any type of surgery, tell the surgeon ahead of time that you are using Tylox. You may need to stop using the medicine for a short time.

Store Tylox at room temperature away from moisture and heat.

Keep track of how many tablets have been used from each new bottle of Tylox. Oxycodone is a drug of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.

What happens if I miss a dose?

Since Tylox is taken as needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of Tylox can be fatal.

Overdose symptoms may include extreme drowsiness, pinpoint pupils, nausea, vomiting, dark urine, jaundice (yellowing of the skin or eyes), confusion, cold and clammy skin, muscle weakness, fainting, weak pulse, coma, blue lips, shallow breathing, or no breathing.

What should I avoid while taking Tylox?

Tylox can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Do not use any other over-the-counter cough, cold, allergy, or pain medication without first asking your doctor or pharmacist. Acetaminophen is contained in many medicines available over the counter. If you take certain products together you may accidentally take too much acetaminophen. Read the label of any other medicine you are using to see if it contains acetaminophen. Avoid drinking alcohol while taking Tylox. Alcohol may increase your risk of liver damage while taking acetaminophen. Cold or allergy medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by oxycodone. Tell your doctor if you regularly use any of these medicines, or any other narcotic pain medicine.
