I have hypothyroidism and want to take some sinus medication. It says don't take if you have thyroid disease.

It sounds like hypothyroidism is classified as thyroid disease. I wouldn't take that medicine!

I am pretty sure that you aren't suppose to take it if you have hyperthyroidism, i think hypo is fine

When the thyroid does not produce enough thyroid hormones for the body, that is the definition of hypothyroidism, or underactive thyroid. The most common cause of hypothyroidism is Hasimoto’s disease, a disorder where the immune system actually attacks the thyroid.
