Patient discussion about certainty

Q. Can certain fruits/veggies make Ritalin less effective? I've heard this about oranges and lemons - is it true? How about other produce? How much does it weaken Ritalin? Will taking a higher dose resolve the problem? (I currently take 10mg morning and 10mg afternoon)

A. As far as I know, oranges and lemons don't affect Ritalin. However, taking the Ritalin with food may increase the amount of drug that actually get into your body, but it depends on the specific formulation (e.g. Concerta isn't affected by food). One that takes Ritalin should avoid alcoholic drinks, since it may cause decrease activity of the brain, and also should avoid herbs of several kinds (yohimbine and ephedra).

THIS IS ONLY A GENERAL ADVICE - I haven't seen you or checked you, so if you have any concerns than you should consult a doctor.

Q. Is there a relation between certain types of allergies and graves? I suffer from graves and have been suffering from allergies since I was real young. Are these two related somehow?? anyone else suffers from both?

A. Not that I know about. However, allergy is quite common, and Graves' disease is also not a rare disease, so it's not impossible for the two to appear in the same person.

Take care,

Q. Are there are certain types of people that have a stronger tendency to become alcoholics?

A. the important part is to remember that you dont really know if you have a tendency to become an alcoholic until you are one, so the safe bet is to just stay away from it and no tell yourself that "it could never happen to you".
