I’m talking better and feel better. I also took l-theanine. I hope there is no interaction!

What time of day is best?

100mg to 200mg a day - therapeutic doses

What do lower doses do?

Where’d you get that figure?

Lower doses can be used - under 100mg but for mood stabilization against depression and mania, doses 100 to 200 is usually used as the starting effective dose range.

I take 250 mg split in two doses morning and night.

I’m on 200 2x/day.

Yeah, but where did you hear that? Doc? WebMD?

It’s time to find a new PDOC for you.

I’ve known this for a long time.
Listen to your doctor.

How long does the effect last in 24 hours?

I couldn’t tolerate doses over 25mg.
Made me too anxious/hypomanic.

This is from the NIH/NIMH. It says that the lowest effective dose for lamotrigine is 100 mg/day


What about for mania long term? @anon17132524

Why don’t you ask your doctor?
No offense.

He doesn’t always know or will dismiss me.

He sees a lot of folk everyday. Stress.

Probably 200mg to 400mg

I take 200 mg of lamotrigine 2X/day. I’ve been on it for years, and my pdoc has never mentioned a time when I’ll stop taking the medication.

You have to start at very low dose to see if you have an allergic reaction to the med (aka Lamictal Rash).

What side effects do you get?

How low of a dose to start? I’m at 25.

25 is a starter dose.
I started lower at 12.5.

Like @anon17132524 mentioned, you have to go up very slowly with Lamotrigine or you can risk getting the Lamictal rash.

Side effects vary but I got anxious on Lamictal.
