What is Primlev?
Oxycodone is an opioid pain medication, sometimes called a narcotic. Acetaminophen is a less potent pain reliever that increases the effects of oxycodone.
Primlev is a combination medicine used to relieve moderate to severe pain.
Primlev may also be used for purposes not listed in this medication guide.
This medicine can slow or stop your breathing, and may be habit-forming. Use only your prescribed dose, and swallow the pill whole to avoid a potentially fatal dose. Never share Primlev with another person.
MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, 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.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use this medicine if you are allergic to acetaminophen (Tylenol) or oxycodone, or if you hvae:
severe asthma or breathing problems; or
a blockage in your stomach or intestines, including paralytic ileus.
To make sure this medicine is safe for you, tell your doctor if you have ever had:
any type of breathing problem or lung disease;
drug or alcohol addiction, or mental illness;
kidney disease, urination problems;
problems with your gallbladder, pancreas, thyroid, or adrenal gland; or
Some medicines can interact with oxycodone 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 oxycodone 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.
Do not breast-feed. Acetaminophen and oxycodone can pass into breast milk and may cause drowsiness or breathing problems in a nursing baby.
How should I take Primlev?
Follow all directions on your prescription label. Oxycodone can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never use this medicine 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.
Oxycodone 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 Primlev is against the law.
Measure liquid medicine with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose. Never crush or break a pill to inhale the powder or mix it into a liquid to inject the drug into your vein.
If you need surgery, tell the surgeon ahead of time that you are using this medicine. You may need to stop using the medicine for a short time.
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 the medicine.
Store at room temperature away from moisture and heat. Keep track of your medicine. Oxycodone 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 can be fatal, especially in a child or other person using this medicine without a prescription. Overdose can cause severe muscle weakness, pinpoint pupils, very slow breathing, extreme drowsiness, or coma.
What should I avoid while taking Primlev?
Do not drink alcohol. Dangerous side effects or death could occur.
This medicine may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine 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.
Primlev 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 this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Like other narcotic medicines, oxycodone can slow your breathing. Death may occur if breathing becomes too weak.
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;
confusion, unusual thoughts or behavior;
weakness, tiredness, fever, unusual bruising or bleeding;
problems with urination; or
liver problems--nausea, upper stomach pain, 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.

feelings of extreme happiness or sadness;
