Urine + for ritalin: I take vyvanse regularlly and was recently given a random drug test at the psych dr. But tested positve for ritalin not vyvanse? ANS: ritalin and vyvanse are very close chemical cousins so depending on which test they used they may either show + test but they cannot tell which one it is. Ask your team doing the test if they cross react in the test they use. ...Read more

I have been on ritalin for adhd for 4 years and I change to vyvanse (lisdexamfetamine) tomorrow, is there anything I should know before taking vyvanse (lisdexamfetamine)? Thanks

The equivalent dose: Of Amphetine is 1/2 the dose of Methylphenidate, branded Ritalin. Multiply ½ of your current total daily dose of MPH x 3 for your equivalent dose of Vyvanse (lisdexamfetamine). You may do well on less because it works for 12-14 hours & has very little " rebound" as it wears off. Max. Adult dose of Vyvanse (lisdexamfetamine) is 70 mg/day. Onset of action is 1 ½ -2 hours, so you might take it earlier. Side effects are same as MPH's. ...Read more

Can you explain to me ritalin crash compared to Vyvanse (lisdexamfetamine) and other ADHD medications?

Can you explain to me ritalin crash compared to Vyvanse (lisdexamfetamine) and other ADHD medications?

There are only two: Stimulants, methylphenidate & Amphetamine. Since 2000, multiple delivery systems of each have been produced. Each differs in onset of action, time of peak clinical effect & duration of action. Longer & more consistent drug delivery gives better symptom control & reduces symptoms of "rebound" ADHD, irritability, emotional lability & the "crash" noted by some teens & adults as the effect wears off ...Read more

I'm prescribed Vyvanse (lisdexamfetamine) but the copay is too expensive for me. Ritalin didn't work. Is Adderall an alternative safe to bring up with my psychiatrist?

I'm prescribed Vyvanse (lisdexamfetamine) but the copay is too expensive for me. Ritalin didn't work. Is Adderall an alternative safe to bring up with my psychiatrist?

Possibly: On the other hand, if it works well for you, check out the Vyvanse (lisdexamfetamine) website. Pharmaceutical companies often have coupons available that can help to defray the cost of co-pays. Good luck. ...Read more

Adderall has been helping me with my illness but I can't sleep. Would vyvanse (lisdexamfetamine) or ritalin be a better option and still give euphoria and clear thoughts?

Adderall has been helping me with my illness but I can't sleep. Would vyvanse (lisdexamfetamine) or ritalin be a better option and still give euphoria and clear thoughts?

Oh, my. Adderall (dextroamphetamine and racemic amphetamine) &: Methylphenidate products are not intended to produce euphoria. Please call your psychiatrist ASAP if you are experiencing a sense that you can hang the moon & set the stars, because it may have triggered an episode of hypomania when added to your Prozac (fluoxetine).I don't know your family history or whether your depression. started before puberty, but some mood disorders reveal themselves at your age. ...Read more

Why would a doctor prescribe my friend Vyvanse (lisdexamfetamine) when he has heavily abused Adderall ritalin and illegal amphetamines like cocaine and meth?

Why would a doctor prescribe my friend Vyvanse (lisdexamfetamine) when he has heavily abused Adderall ritalin and illegal amphetamines like cocaine and meth?

UNINFORMED: I would wonder if your "friend" has been honest about the medications that have been abused. Vyvanse (lisdexamfetamine) is a prodrug and is not active if snorted ot injected. Still it is an amphetamine. Your friend will eventually be caught as there are more and more externally systems that monitor for doctor shopping and drug abuse. ...Read more

What are the differences in dosage between ritalin (methylphenidate) and adderall, to achieve the same effects?

What are the differences in dosage between ritalin (methylphenidate) and adderall, to achieve the same effects?

Rough estimate below: D-amphetamine (dexedrine) is about twice as potent as methylphenidate (ritalin), so 10 mg of the former is roughly the same as 20 mg of the latter. Adderall (dextroamphetamine and racemic amphetamine) is a mixture of 1/2 d-amphetamine plus 1/2 d- & l-amphetamine (the latter being inactive with respect to adhd. So, conversion from Ritalin to Adderall (dextroamphetamine and racemic amphetamine) is about 20 mg down to 15 mg. But, individual response varies, so that's just a start. ...Read more
