How can you get insurance if you are taking drugs for ADD?

You shouldn't be denied coverage because of medication you take for an illness. It would possibly be considered a pre-exsisting condition, and affect the coverage for ADD. Most insurance plans have a pre-existing condition policy.

Answer

Try another Insurance Company or Agent. Do you have State Disabilty Coverage? It's not a whole lot, but it's something.

I'm not sure how taking drugs for ADD would preclude you from working, thereby qualifying you for disability insurance if I understand you correctly. If anything, the drugs you take for ADD should improve your work performance (increased concentration, decreased distraction, etc.). So I would say, probably not.
