Methadone is a slow-acting drug, which means it takes a few days to feel the full effects of an adjustment in your dose. It also means that once you are stabilized, should you miss a dose, the effects of withdrawal will come on more slowly than they do with fast-acting opioids, such as heroin.
Some clients want to increase their dose rapidly when they first start treatment. This can be very dangerous as the drug takes a few days to get to its peak levels. Your doctor will explain more about Methadone dosing at your appointments.
Methadone works best when it’s taken once a day at the same time every day. This helps to maintain a stable level of methadone in your body, keeping you feeling “normal.”
