What should I discuss with my healthcare provider before using methadone (Methadone Hydrochloride)?
Taking methadone improperly will increase your risk of serious side effects or death. Even if you have used other narcotic medications, you may still have serious side effects from methadone. Follow all dosing instructions carefully.
Methadone may be habit forming and should be used only by the person it was prescribed for. Never share Methadone with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
Do not use this medication if you have ever had an allergic reaction to a narcotic medicine (examples include codeine, morphine, Oxycontin, Darvocet, Percocet, Vicodin, Lortab, and many others). You should also not take methadone if you are having an asthma attack or if you have a bowel obstruction called paralytic ileus.
To make sure you can safely use methadone, tell your doctor if you have any of these other conditions:
- a personal or family history of "Long QT syndrome";
- asthma, COPD, sleep apnea, or other breathing disorders;
- liver or kidney disease;
- underactive thyroid;
- curvature of the spine;
- a history of head injury or brain tumor;
- epilepsy or other seizure disorder;
- low blood pressure;
- gallbladder disease;
- Addison's disease or other adrenal gland disorders;
- enlarged prostate, urination problems;
- mental illness; or
- a history of drug or alcohol addiction.
FDA pregnancy category C. It is not known whether Methadone will harm an unborn baby. Methadone may cause addiction or withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using Methadone.
Methadone can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Older adults and people with debilitating conditions may be more sensitive to the effects of this medication.
How should I use methadone (Methadone Hydrochloride)?
Use exactly as prescribed. Never use Methadone in larger amounts, or for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Like other narcotic medicines, methadone can slow your breathing, even long after the pain-relieving effects of the medication wear off. Death may occur if breathing becomes too weak. Never use more methadone than your doctor has prescribed. Call your doctor if you think the medicine is not working.
When methadone is used as part of a treatment program for drug addiction or detoxification, you will receive the medication through a clinic or special pharmacy.
Your doctor may recommend that methadone be given to you by a family member or other caregiver. This is to make sure you are using the medicine as it was prescribed as part of your treatment.
Additional forms of counseling and/or monitoring may be recommended during treatment with methadone.
Methadone is available in tablets, dispersible tablets, oral solution (liquid) and as an injection. The pill and oral liquid forms of methadone must never be used to make a methadone injection.
Measure the liquid form of methadone with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
The methadone dispersible tablet (Diskets) is made to be dissolved in water. Do not chew, crush, or swallow the tablet whole. Place the tablet into a 4-ounce glass of water, orange juice, or other citrus-flavored non-alcoholic beverage and allow the tablet to disperse in the liquid. The tablet will not dissolve completely. Drink this mixture right away. To make sure you get the entire dose, add a little more liquid to the same glass, swirl gently and drink right away.
Store at room temperature away from moisture and heat.
After you have stopped using this medication, flush any unused pills down the toilet.
Keep track of how much of this medicine has been used. Methadone is a drug of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.
