What is Levo-Dromoran?

Levo-Dromoran is an opioid pain medication, sometimes called a narcotic.

Levo-Dromoran is used to treat moderate to severe pain.

Levo-Dromoran may also be used for purposes not listed in this medication guide.

Important Information

Levo-Dromoran can slow or stop your breathing, and may be habit-forming. MISUSE OF Levo-Dromoran 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.

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 Levo-Dromoran if you are allergic to it.

To make sure Levo-Dromoran is safe for you, tell your doctor if you have ever had:

  • any type of breathing problem or lung disease;

  • heart disease;

  • stomach problems;

  • liver disease;

  • a head injury, brain tumor, or seizures;

  • drug or alcohol addiction, mental illness;

  • urination problems; or

  • problems with your gallbladder, adrenal gland, or thyroid.

If you use Levo-Dromoran 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 while taking Levo-Dromoran. This medicine may cause serious side effects in the nursing baby.

Levo-Dromoran is not approved for use by anyone younger than 18 years old.

How should I take Levo-Dromoran?

Follow all directions on your prescription label. Levo-Dromoran can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Your dose needs may be different if you are already being treated with a similar opioid medicine and your body is tolerant to it.

Levo-Dromoran may be habit-forming. Never share Levo-Dromoran 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 this medicine is against the law.

Do not stop using Levo-Dromoran suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using this medicine.

Store at room temperature away from moisture and heat. Keep track of your medicine. Levo-Dromoran 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.

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

What happens if I miss a dose?

Since Levo-Dromoran 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 take 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. A Levo-Dromoran overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, or coma.

What should I avoid while taking Levo-Dromoran?

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

Levo-Dromoran may impair your thinking or reactions. Avoid driving or operating machinery until you know how Levo-Dromoran will affect you. Dizziness or severe drowsiness can cause falls or other accidents.

Levo-Dromoran side effects

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

Like other narcotic medicines, Levo-Dromoran can slow your breathing. Death may occur if breathing becomes too weak.

A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Stop using Levo-Dromoran and call your doctor at once if you have:

  • slow heart rate, weak pulse, weak or shallow breathing, blue lips or fingernails;

  • a light-headed feeling, like you might pass out;

  • mood changes, confusion, unusual thoughts or behavior;

  • seizure (convulsions);

  • pounding heartbeats or fluttering in your chest;

  • severe stomach pain; or

  • severe constipation, painful or difficult urination.

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 may include:

  • dizziness, drowsiness, blurred vision, memory problems;

  • nausea, vomiting, dry mouth;

  • constipation;

  • itching, sweating;

  • flushing (warmth, redness, or tingly feeling); or
