I take 20 mg of lexapro at 8 pm and when I wake up the next morning I take 30 mg of adderall xr around 4:30-5am. This morning after taking the lexapro last night, I accidentally took another 20mg. I tried to drink lots of water and throw it up, but no go. I shrugged it off and took the adderall as usual. Will this cause mild to moderate effect of serotonin syndrome, or will I just feel like crap all day? Also, I've been prescribed clonazepam for anxiety. Will taking this if I do experience any interaction symptoms help?
