The name is actually Thimerosal. I have a base metal allergy, so I learned about that years ago. Murine® and Visine® used to have that preservative in them. Instead of getting the red out, my eyes turned red all over along with the burning.
But, yes that is/was the factor that has been suspected to cause the autism but the tricky part was that it was used in vials or ampules for storage before any medication was ever placed in them. It's a crap shoot to know if it is there or not.
Same thing, different trade name. They used to sell it in small bottles as an antiseptic for scrapes and cuts. When I was a boy I got a nasty cut on my foot while I was at my grandparent's. Grandpa painted it with mercurochrome. When my dad saw the blue paint and asked what it was he kinda wigged out because of the mercury. We only used methiolate you see. Little did we know back then, methiolate has more mercury in it than mercurochrome. It just doesn't have mercury in the name.
