How Long Does Ritalin Stay In Your System
How long does ritalin stay in your system after you stop taking the medication? I was put on it for a few days but stopped due to the side effects. I am starting a new job and will be drug tested next week and am worried if I need to tell them or not.
Very short: The half life of Ritalin (methylphenidate) is quite short. If you have stopped taking the drug after a few days, and your test is not for a few more days, chances are you will not test positive. It would be wise, however, to be upfront about any current medications you are taking when you submit your sample. ...Read more

Few months: It depends on the dose you were on when you stopped and how long you were on it. Usually when people take a few months off (summer break) they may be able to start again at a lower dose (20 to 30% lower), but will quickly need to increase back to their previous dose (within a month). That's just my opinion. You might get a different answer from another doc. ...Read more

I've been taking 10 mg ritalin (methylphenidate) twice a day for three weeks. I no longer feel the effects. Have I developed a tolerance? Should I ask for ritalin (methylphenidate) xr?
Tolerance OK term: I am glad you use the term tolerance which is a decrease of the effect of the medication over time; the person becomes accustomed to it. It is different from addiction (craving, withdrawal symptoms, chronic compulsive use; and different from physical dependence). A dose of 10 mg of Ritalin (methylphenidate) twice a day is a good therapeutic dose. I do not know why you take it but ask your health provider (nuvigil?). ...Read more

If I was looking to do more than moderate drinking, how long would I have to wait after taking extended release Ritalin (methylphenidate) in order to be safe?
Safe is relative: Drinking more than moderately increases risk of accidents, health problems, legal and social conflict, and emotional difficulty. So, alcohol in more than moderate amounts is not necessarily safe. Add Methylphenidate (immediate or extended release) and risks increase. Avoiding the combination of the two may help reduce risk but risk would still be present. You may wait 4-7 days at most. ...Read more

I know the text book answer is NO, BUT if I take methadone in the early morning & take Ritalin (methylphenidate) in the afternoon (not long term), would ritalin (methylphenidate) work?
May be: In theory the two drugs don't interact, as they have opposite effects, not additive effects, methadone has a long half-life, it stays in the system longer, at least 16 hours, its elimination depends on many factors, how active is the liver, how acidic is the urine for example or alkaline, etc. Also depends on other medicines you are on, counsel your doctor again, both are schedule II medications, ...Read more

It should be a slow and deliberate process to find right treatment. Treatment is long term. Be patient. ...Read more
