When I took 200 mg of Iodoral the first time 12 months ago, my nose ran and dripped like a spigot along with headache and body ache. I backed off to 150 or 175 I don't remember which and stayed at that level for a week before ramping back up. The nasel drip started but ended quickly.
If I recall correctly nasal drip also occured at 500mg and 800mg, but only lasted a day of two at most. I don't recall ever seeing any blood spots in the mucous.
