Levomethadyl belongs to the group of medicines known as narcotic analgesics. It is used as a substitute for illegal narcotics in addiction treatment programs. levomethadyl is not a cure for addiction. It is used as part of an overall program that may include counseling, attending support group meetings, and other treatment recommended by your doctor.
Levomethadyl helps prevent the withdrawal symptoms that may occur when an addict stops using other narcotics. In detoxification programs, the amount of levomethadyl used is slowly decreased until an addict becomes drug-free. In maintenance programs, it is used on a long-term basis to help narcotic addicts stay away from street drugs. With long-term use, levomethadyl may decrease an addict's craving for other narcotics.
Another narcotic, methadone, is also used in detoxification and maintenance programs. Methadone begins to work faster than levomethadyl does when treatment is started, but it has to be taken every day. Levomethadyl starts to work slowly, but it does not have to be taken every day. Therefore, some people may start treatment with methadone and then change over to levomethadyl after several weeks. Other people may receive only one medicine or the other during the entire time of treatment. Your doctor and your counselor at the clinic will decide on the best treatment plan for you.
In the U.S., levomethadyl was available only in government-approved treatment clinics.
The manufacturer discontinued ORLAAM® (levomethadyl) in the United States in September 2003.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For levomethadyl, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to levomethadyl or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
In the U.S., the law does not allow levomethadyl to be used for treating addicts younger than 18 years of age.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of levomethadyl in the elderly with use in other age groups.

Using levomethadyl with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of levomethadyl. Make sure you tell your doctor if you have any other medical problems, especially:
Most patients are given their dose of levomethadyl at the clinic. You may be able to take some doses of your levomethadyl at home if your health care professional feels you are responsible to do that. Most people will have to go to the clinic 3 times a week.
The dose of levomethadyl will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of levomethadyl. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
Taking levomethadyl is only part of your treatment. Your doctor and your counselor at the clinic will make a treatment plan for you to follow. This plan may include seeing your counselor at the clinic regularly, attending support group meetings, and making changes in your lifestyle that will help you stay away from illegal drugs. The success of your treatment will depend on how carefully you follow your treatment plan.
levomethadyl will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or other narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. It is very important that you do not drink alcoholic beverages or take any CNS depressants during levomethadyl treatment unless you have been directed to do so by a doctor who knows that you are taking levomethadyl. Even if you continue to have some withdrawal symptoms and to crave narcotics for a while after levomethadyl treatment has been started, do not use illegal narcotics or other CNS depressant ``street'' drugs. Taking ``street'' drugs together with levomethadyl has caused some people to die from an overdose.
Levomethadyl may cause some people to become drowsy, especially when treatment is started or the dose is increased. Make sure you know how you react to levomethadyl before you drive, use machines, or do anything else that could be dangerous if you are drowsy or are not alert and clearheaded. This effect usually goes away after a few days, when your body gets used to the medicine. However, tell your counselor at your next visit to the clinic if any dose causes drowsiness that is severe enough to interfere with your activities.
Dizziness, lightheadedness, or even fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve dizziness or lightheadedness.
Tell all health care professionals you go to that you are taking levomethadyl. This is especially important if any kind of surgery or emergency treatment is needed. Serious side effects can occur if your health care professional gives you certain other medicines without knowing that you are taking levomethadyl.
Using narcotics such as levomethadyl for a long time can cause severe constipation. To prevent this, your counselor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.
Levomethadyl may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
For women only:
Some people may be transferred to methadone after receiving levomethadyl for a while. If you are given any take-home doses of methadone, do not take the first dose of methadone for at least 48 hours (2 days) after your last dose of levomethadyl. Taking the 2 medicines too close together may cause an overdose.
If you think you may have taken an overdose of narcotics, get emergency help right away. Taking an overdose of narcotics, or taking alcohol or CNS depressants with narcotics, may lead to unconsciousness or death. Signs of overdose include convulsions (seizures); confusion; severe dizziness, drowsiness, nervousness, restlessness, or weakness; and very slow or troubled breathing. It is very important that the emergency room doctor knows that you are physically dependent on a narcotic called levomethadyl, that using naloxone to treat your overdose is very likely to cause withdrawal symptoms, and that you will need to be watched for a long time because levomethadyl's effects last for several days. However, you may not be able to give this information to the doctor yourself. Therefore, you should direct friends and family members to give this information to the doctor, if necessary.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
