What You Need to Know About Methadone


Updated June 18, 2014

Methadone is an opiate medication used to treat pain. It is becoming increasingly popular in the palliative care and hospice setting, because it is very effective, causes less adverse effects than other opiates and is inexpensive. (See "Why Would I Use Methadone?")

Methadone may come generically or in the brand names Dolphine, Methadone Diskets, Methadone Intensol, Methadose or Metadol (in Canada).

How Do I Take It?

Methadone can be taken with or without food. Methadone is available as a tablet, dispersible tablet or liquid. The tablet may be taken with water or liquid of choice; the dispersible tablet may be dissolved in water or juice, and the liquid may be mixed with a small amount of water or juice to dilute the taste, if desired.

What Precautions Should I Take?

You should always tell your health care provider all the medications you are taking. Methadone may interact with some medications, so it’s important that your doctor and pharmacist have a complete list of everything you are taking. You should avoid grapefruit and grapefruit juice while taking methadone.

Methadone may make you drowsy. Avoid alcohol as this can make it worse. Also avoid driving and other tasks that require your attention until you know how it’s going to affect you.

What are the Side Effects of Methadone and What Can I Do About Them?

Sleepiness, light-headedness and blurred vision or cloudy thinking: Take precautions for safety by avoiding driving or other tasks that require a clear mind until you know what your reaction is to the medication.

Dizziness: Take your time to get up from a sitting or lying position. When lying down, sit up slowly and dangle your feet off the side of the bed or chair for a minute or two before standing.

Nausea and/or Vomiting: Eat smaller, more frequent meals. Sucking on hard candy or chewing gum may also help. A cold wash cloth to the face and neck and fresh air can also be helpful. If nausea and vomiting are severe or persistent, your physician may prescribe anti-emetics to treat it.

Constipation: Drinking more liquids and eating a diet with adequate fiber can help combat constipation. Try to stay active or exercise if possible. Your doctor may also recommend a stool softener or laxative to prevent or treat constipation. Keep a log of your bowel movements, and alert your health care provider if they start to slow down in frequency or become difficult to pass.

Why Would I Need to Call My Health Care Provider?

You would want to call your health care provider if you suspect an allergic reaction. Signs of a life-threatening reaction include tightness in the chest or throat, wheezing or difficulty breathing, severe itching, blue skin color or swelling of the face, lips, tongue or throat.

You should also contact your health care provider if your pain is not getting better or if you feel like you are receiving too much medication. Signs that your dose may be too high include severe drowsiness, dizziness or passing out, significant change in ability to think clearly and significant decrease in breathing.
