What is the most important information I should know about levorphanol?

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.

What is levorphanol?

What is levorphanol?

Levorphanol is an opioid medicine that is used to treat moderate to severe pain.

Levorphanol may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking levorphanol?

What should I discuss with my healthcare provider before taking levorphanol?

You should not use levorphanol if you are allergic to it, or if you have:

  • severe asthma or breathing problems; or
  • a stomach or bowel obstruction (including paralytic ileus).

Tell your doctor if you have ever had:

  • breathing problems, sleep apnea (breathing stops during sleep);
  • a head injury, or seizures;
  • drug or alcohol addiction;
  • liver or kidney disease;
  • urination problems; or
  • problems with your gallbladder, pancreas, or thyroid.

If you use opioid 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 opioids may need medical treatment for several weeks.

Ask a doctor before using opioid medicine if you are breastfeeding. Tell your doctor if you notice severe drowsiness or slow breathing in the nursing baby.

Levorphanol is not approved for use by anyone younger than 18 years old.

How should I take levorphanol?

How should I take levorphanol?

Follow the directions on your prescription label and read all medication guides. Never use levorphanol in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.

Your dose needs may be different if you recently used opioid medicine and your body is tolerant to it (ask your doctor if you're not sure).

Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.

Do not stop using levorphanol suddenly after long-term use, or you could have serious withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

Never crush or break a levorphanol pill to inhale the powder or mix it into a liquid to inject the drug into your vein. Doing so could result in death.

Store at room temperature away from moisture and heat. Keep track of your medicine. You should be aware if anyone is using it 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?

What happens if I miss a dose?

Since levorphanol is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An opioid overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.

Your doctor may recommend you get naloxone (a medicine to reverse an opioid overdose) and keep it with you at all times. A person caring for you can give the naloxone if you stop breathing or don't wake up. Your caregiver must still get emergency medical help and may need to perform CPR (cardiopulmonary resuscitation) on you while waiting for help to arrive.

Anyone can buy naloxone from a pharmacy or local health department. Make sure any person caring for you knows where you keep naloxone and how to use it.

What should I avoid while taking levorphanol?

What should I avoid while taking levorphanol?

Do not drink alcohol. Dangerous side effects or death could occur.

Avoid driving or hazardous activity until you know how this medicine will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.

What are the possible side effects of levorphanol?

What are the possible side effects of levorphanol?

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Call your doctor at once if you have:

  • noisy breathing, sighing, shallow breathing, breathing that stops;
  • a slow heart rate or weak pulse;
  • a light-headed feeling, like you might pass out;
  • mood changes, unusual thoughts or behavior;
  • severe stomach pain, severe constipation;
  • high levels of serotonin in the body --agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea; or
  • low cortisol levels -- nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.

Serious breathing problems may be more likely in older adults and those who are debilitated or have wasting syndrome or chronic breathing disorders.

Common side effects may include:

  • nausea, vomiting, stomach pain;
  • constipation;
  • dizziness, drowsiness;
  • tiredness; or
  • headache.

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 levorphanol?

What other drugs will affect levorphanol?

You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

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;
  • a sedative like Valium --diazepam, alprazolam, lorazepam, Xanax, Klonopin, Ativan, and others;
  • drugs that make you sleepy or slow your breathing --a sleeping pill, muscle relaxer, medicine to treat mood disorders or mental illness; or
  • drugs that affect serotonin levels in your body --a stimulant, or medicine for depression, Parkinson's disease, migraine headaches, serious infections, or nausea and vomiting.

This list is not complete. Other drugs may affect levorphanol, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here.
