Will tegretol reduce the lamictal level by about 50%.....for example would 100mg of lamictal really be approx. 50 mg with 600 tegretol?

Not really: If you are talking about using the meds to control seizures, no. Cannot compare these meds on a basis of one being equal to or replacing x percent of another med. It is best to discuss with your neurologist re: adjusting doses of meds to control seizures. Hope this was helpful. Best of luck. Dr R ...Read more

I am on lamictal for bi polar. What is the highest theraputic dose I can take. I am not on any other psyc meds.?

Check with Doctor: I don't think it's a good idea to increase your dose based on what some of us might say here on healthtap. I hope you agree. I also wonder about the symptoms you have which might cause you to want a dosage increase. Too much Lamictal can have side-effects. The package insert for Lamictal recommends a maximum dose of 200 mgs/day, although I've seem some on higher doses than that. Again, ask the dr. ...Read more

Can I take probiotics with my meds for BiPolar II, Cymbalta (duloxetine) and Lamictal, or does that risk increasing Seratonin levels?

Can I take probiotics with my meds for BiPolar II, Cymbalta (duloxetine) and Lamictal, or does that risk increasing Seratonin levels?

Probably fine: The major concern with Bipolar medications is the pharmacological interaction that might occur. Because probiotics act locally in the gut, there is no reason to not take them. That said, I'm unsure if they will help you in any way. .. But they should be ok to take with Cymbalta (duloxetine) & Lamictal. ...Read more
