- USES
-
- Methadone is a narcotic analgesic (pain reliever) that acts directly on
- the central nervous system (brain and spinal cord). It is used to relieve
- moderate to severe pain. It is also used to detoxify narcotic addicts and to
- provide temporary maintenance treatment for them.
-
- TREATMENT
-
- To avoid stomach upset, take methadone with food or milk. This
- medication is most effective if you take it at the onset of pain, rather than
- when the pain becomes intense.
- Measure the dose of the solution form of this medication carefully with a
- specially designed 5-ml measuring spoon. An ordinary kitchen teaspoon is not
- accurate enough.
- If you are taking this medication on a regular schedule and you miss a
- dose, take the missed dose as soon as possible, unless it is almost time for
- your next dose. In that case, do not take the missed dose at all; just return
- to your regular dosing schedule. Do not double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Constipation, dizziness, drowsiness, dry mouth, false sense of
- well-being, light-headedness, loss of appetite, nausea, or sweating. These
- side effects should disappear as your body adjusts to the medication.
- If you are constipated, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads), exercise, and
- drink more water (unless your doctor directs you to do otherwise).
- Chew sugarless gum or suck on ice chips or a piece of hard candy to
- reduce mouth dryness.
- If you feel dizzy or light-headed, sit or lie down for a while; get up
- from a sitting or lying position slowly, and be careful on stairs. Take
- special care when operating potentially dangerous equipment.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- anxiety, breathing difficulties, excitability, fainting, fatigue, flushing,
- painful or difficult urination, palpitations, pinpoint pupils of eyes, rash,
- restlessness, sore throat and fever, tremors, or weakness.
-
- INTERACTIONS
-
- Methadone interacts with several other types of medications:
- 1. Concurrent use of it with other central nervous system depressants
- (such as alcohol, antihistamines, barbiturates, benzodiazepine tranquilizers,
- muscle relaxants, and phenothiazine tranquilizers) or with tricyclic
- antidepressants can cause extreme drowsiness.
- 2. A monoamine oxidase (MAO) inhibitor taken within 14 days of this
- medication can lead to unpredictable and severe side effects.
- 3. Rifampin and phenytoin can decrease the blood levels and effectiveness
- of methadone.
- 4. The combination of cimetidine and this medication can cause confusion,
- disorientation, and shortness of breath.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to methadone or to any other narcotic analgesic.
- * Tell your doctor if you now have or if you have ever had acute
- abdominal conditions, asthma, brain disease, colitis, epilepsy, gallstones or
- gallbladder disease, head injuries, heart disease, kidney disease, liver
- disease, lung disease, mental illness, emotional disorders, enlarged prostate
- gland, thyroid disease, or urethral stricture.
- * If this drug makes you dizzy or drowsy, do not take part in any
- activity that requires alertness, such as driving a car or operating
- potentially dangerous machinery.
- * Before having surgery or any other medical or dental treatment, be sure
- to tell your doctor or dentist that you are taking this medication.
- * Methadone has the potential for abuse and must be used with caution.
- Usually, it should not be taken on a regular schedule for longer than ten days
- (unless your doctor directs you to do so). Tolerance develops quickly; do not
- increase the dosage or stop taking the drug abruptly unless you first consult
- your doctor. If you have been taking large amounts of this medication or if
- you have been taking it for long periods of time, you may experience
- withdrawal symptoms (muscle aches, diarrhea, gooseflesh, runny nose, nausea,
- vomiting, shivering, trembling, stomach cramps, sleep disorders, irritability,
- weakness, excessive yawning, or sweating) when you stop taking it. Your
- doctor may, therefore, want to reduce the dosage gradually.
- * Be sure to tell your doctor if you are pregnant. The effects of this
- medication during the early stages of pregnancy have not been thoroughly
- studied in humans. However, regular use of methadone in large doses during
- the later stages of pregnancy can result in addiction of the fetus, leading to
- withdrawal symptoms (irritability, excessive crying, tremors, fever, vomiting,
- diarrhea, sneezing, or excessive yawning) at birth. Also, tell your doctor if
- you are breast-feeding an infant. Small amounts of this medication may pass
- into breast milk and cause excessive drowsiness in the nursing infant.
