Patient discussion about interaction

Q. Is there any possibility for drug interactions when bipolar drugs and herbal drugs are taken together. My mom is on lithium. Recently she tried some herbal treatment as it’s said to have no side effects. Is there any possibility for drug interactions when bipolar drugs and herbal drugs are taken together.

A. my recommedation is to talk to your physician before taking any OTC medication or herbal meds.

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.
