how do people get high off of claritin d?

It's not the medicine that makes them get high. It's the combination of some of the ingredients with others that make meth, which is way in some states the sell of these over the counter drugs are regulated.

It could be the claritin..you could also be developing high blood pressure. One low reading doesn't eliminate high blood pressure. I suggest reading the link below. If your blood pressure is already slightly elevated...then yes..the claritin could increase it. Keep an eye on your blood pressure. Perhaps discontinue the Claritin and see if it goes back down to normal, with several readings. I have high blood pressure (since my 20's) and cannot take Claritin.

just stop taking it. It only stays in your system 24 hours. If your allergy symptoms return, maybe you need to keep taking it.

I never heard of people doing that they must have too much time on their hands

They take too many- it can make your brain feel all fuzzy. Bad idea- dehydrates them. It will make you sick. Promise.
