Forms of methadone and some general information:

Methadone comes as a pill, a dispersible tablet (it can be dissolved in liquid may be white or orange depending on pharmacy company of origin), a solution (liquid may be red or clear depending on company of origin), and a concentrated solution (liquid that must be diluted before use) to take by mouth.  Typically the pill form will be prescribed for pain management and the other forms are usually prescribed in the treatment of opiate addiction.  When methadone is used to relieve pain, it may be taken every 4 to 12 hours. If you take methadone as part of a methadone maintenance treatment program, your doctor will prescribe the dosing schedule that is best for you. This is usually one dose per day. Your doctor may change your dose of methadone during your treatment. Your doctor may decrease your dose or tell you to take methadone less often as your treatment continues. You should ask your doctor if you have any questions about how much methadone you should take or how often you should take the medication. Methadone is considered to be in the class of habit-forming drugs. You should notify your doctor if you find that you are experiencing cravings and/or experience pain or notice any other unusual changes in your behavior or mood. Do not abruptly stop taking methadone without talking to your doctor (you are likely to have severe withdrawal symptoms). Your doctor will probably want to decrease your dose gradually. If you suddenly stop taking methadone or start gradually decreasing your dose, you may experience withdrawal symptoms such as restlessness, teary eyes, runny nose, yawning, sweating, chills, muscle pain, cramps, and widened pupils (black circles in the middle of the eyes).
