So I've started feeling dizzy lightheaded on April19th. Started taking Interferon on May 28th then Inosine Pranobex on June 8th. I'm pretty sure one or both of these medicine gave me ptosis. They both affect Immune system. So is thymus. Thymus problems give people myasthenia gravis. I don't know how exactly, but I'm almost certain that these pills/suppositoriums give you heavy eyelids!!! Anyone else noticed the same weirdness?
