What is Lorcet?
Hydrocodone is an opioid pain medication, sometimes called a narcotic.
Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone.
Lorcet is a combination medicine used to relieve moderate to severe pain.
Lorcet may also be used for purposes not listed in this medication guide.
Lorcet can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have pain in your upper stomach, loss of appetite, dark urine, or jaundice (yellowing of your skin or eyes).
Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Before taking this medicine
You should not use this medicine if you are allergic to acetaminophen (Tylenol) or hydrocodone.
To make sure this medicine is safe for you, tell your doctor if you have ever had:
a drug or alcohol addiction;
asthma or other breathing disorder; or
low blood pressure, or if you are dehydrated.
Some medicines can interact with Lorcet and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take stimulant medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
If you use narcotic medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Acetaminophen and hydrocodone can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
How should I take Lorcet?
Follow all directions on your prescription label. Never take Lorcet in larger amounts, or for longer than prescribed. An overdose can damage your liver or cause death. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Always check your bottle to make sure you have received the correct pills (same brand and type) of medicine prescribed by your doctor.
Hydrocodone may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away Lorcet is against the law.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
If you need surgery or medical tests, tell the doctor ahead of time that you are using this medicine.
Do not stop using this medicine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using Lorcet.
Store at room temperature away from moisture and heat. Keep track of your medicine. Hydrocodone is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Since this medicine is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of Lorcet can be fatal.
The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.
Overdose can also cause severe muscle weakness, pinpoint pupils, very slow breathing, extreme drowsiness, or coma.
What should I avoid while taking acetaminophen and hydrocodone?
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how Lorcet will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.
Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen.
Lorcet side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Stop taking Lorcet and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling. If you have this type of reaction, you should never again take any medicine that contains acetaminophen.
Call your doctor at once if you have:
noisy breathing, sighing, shallow breathing;
slow heartbeat or weak pulse;
a light-headed feeling, like you might pass out;
sudden weakness or ill feeling, fever, chills, sore throat, unusual bruising or bleeding;
confusion, unusual thoughts or behavior;
painful or difficult urination;
liver problems--nausea, upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Serious side effects may be more likely in older adults and those who are overweight, malnourished, or debilitated.
Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.
Common side effects include:
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect Lorcet?
Narcotic (opioid) medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:
other narcotic medications--opioid pain medicine or prescription cough medicine;
drugs that make you sleepy or slow your breathing--a sleeping pill, muscle relaxer, tranquilizer, antidepressant, or antipsychotic medicine.
This list is not complete. Other drugs may interact with acetaminophen and hydrocodone, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
