"Be very careful with this medication as it may lead to pseudotumor cerebra which is a very serious side effect (though pretty rare) that can cause permanent vision loss. I was only on the medication from the end of November through middle of January; I was taking it twice a day. The beginning of January I started to have constant horrible headaches then tunnel vision when standing. I then started having severe head and neck pain, dizziness, my vision would go in and out and I felt an intense pressure in my head. I eventually ended up spending well over a week in the hospital, had 3 spinal taps due to very high ICP and in the end with a VP shunt in my brain with a tube to my stomach that I'll have the rest of my life."
