Will a multivitamin deplete the effect of Concerta or just with stims like Adderall?

> MaximeIt's well known not to take Vitamin C, which is in every multivitamin, with Adderall because it absorbs and diminishes the med. I didn't know if it was also the same for Concerta, Ritalin, etc.

Vitamin C? And it's a water soluble vitamin too. Fondly, Phillipa

Well I guess that is one well known fact that I didn't know.
I'm going to look it up and see if you are right. It's not that I don't believe ... it's just my nature.

Theo is spot on:Foods and drugs that make your stomach/intestinal tract acidic may decrease absorption of dextroamphetamine. A partial listing of these items includes: fruit juices, reserpine, sodium acid phosphate, vitamin C, guanethidine.
Thanks Theo! I learned something new today. I don't know about Concerta, but I bet I can find out!

Could this be part of the reason grapefruit is not allowed with a lot of meds? But why just grapefruit juice, why not OJ, etc. Anyone that is acidic? Fondly, Phillipa

Yup, same thing for Concerta. Plus I also found out that a fatty breakfast can decrease the absorption as well. No Vitamin C for an hour before or after.
Which leads me to a concern. What about all these little kids who are taking the med. What if they are being deprived of Vitamin C because of this. It's been proven that vitamin C helps people think more clearly. So maybe parents should be giving their kids more nutrients in their meals and less ritalin! But that is another topic altogether.

No, grapefruit inhibits the enzyme responsible for metabolism of some drugs, like Buspar.
Why couldn't you take something to raise the pH in your stomach and still take the vitamins you need? I've read several threads here that talk about baking soda or whatever and amphetamines.

Basically, I'm going to take my Concerta about 7:00am and start taking my vitamins about 3:00pm.
I think 8 hours after my Concerta dose shouldn't create problems. There will also be 16 hours between taking my vitamins and the next dose of Concerta.
I didn't see anything about concerns with Concerta anyway. I just saw it with amphetamine stims.
I'm suprised I haven't had any response from people taking Concerta. Do all or any that have responded so far take a stim?

According to what I read, one hour is sufficient. There are some who believe that depriving children of fruit juice may not be worth the risk of them not having enough Vitamin C. The article said there wasn't enough evidence that Vitamin C limited the effect of Ritalin (and Concerta).
BTW, not MANY people here take Concerta or Ritalin because they get irritable on it.

I don't. I am passionate with anything to do with the medical field and natural health field. Since I do take valium and I am involved professionally with a Health and Wellness Company, I'm always researching and looking for things to help both myself and others. Fondly, Phillipa

Oh No! I've been scared to take my first dose of Concerta, I've had it a week now and almost feel like I need to take a day off to see how I'll react!! I get this way when trying a med I've never taken.I thought Concerta was supposed to release better and be much smoother than plain immediate release Ritalin?

Vitamin C Does cause Amphetamines to loss power, because it's a urinary acidifier, however it,(and other urinary acidifiers) have no effect on Methyphenidate.
Its a different animal-sorry

Well I don't believe everything I read on the Internet, but I did find a couple of sites that said it did. I would be happier if I found an actual medical article about it. So for ME the jury is out.

According to the PDR, which I and every Doc and medical person in this country has, Amphetamines are listed as being adverse to Urinary Acidifires, Methylphenidate has no such adverse listing.
Maybe some folks notice a difference, Maybe.

I take Concerta & dexedrine each morning.
When I took just Concerta I would have granola
+ two glasses of juice each morning. I switched
to soy milk once I began taking dexedrine because
the juice reduced effectiveness of the dexedrine.It has no obvious effect on Concerta.

I take Concerta and Provigil, usually with a huge glass of water. I notice the difference of the effect of meds with different breakfast and timing of med and meals.
Neuropsych as my other Docs stress some need for 'a' multivitamin and never mentioned to exclude vit C.
I don't agree with the multivitamin mantra of my Docs, like a one size shoe to fit all, and include vit C rather selectively.
It might very well be a good idea to take vitamins in the evening -------- if I will remember...
Thank you

Actually, I'm not wrong. If you read the original post, I simply wanted to confirm the interaction with Vitamin C just pertains to amphetamines and not Concerta. I never stated there is an interaction with Concerta. Get it straight and do your homework before stating somebody's wrong!

Ouch!
That hurt,
If you stated Amphets only! then you and I are in agreement, I may? have misread your FIRST post, but both Aloashirt and I take Methyphenidate and we BOTH notice no difference when taken with juice or not,
I was not attacking you ok? only parlaying published medical info.
We both agree-okey?
