Are there any supplements that I should stay away from while I'm taking Claritin D?

I've taken JW, SD and PP with generic Claritin without any problems

Claritin D gives me a stimulant effect, I'd just take it easy on the thermogenics/fat burners.

It appears that the Claritin-D comes in 12 and 24 hr. versions, both with time-release dosing of pseudoephedrine at roughly 1 mg. per hour. Sensitivity to ECA (if you have ever had it) would be similar to sensitivity to this as they are similar chemicals.

I wouldn't be shocked if there was an increased diuretic/thermogenic effect from the "D" in the claritin...regular claritin wouldn't have this problem. I would be sure...if nothing else...to to drink more water at a minimum while on the D.

As for avoiding supps...just keep an eye on BP if taking other stims.
