My neurologist currently has me receiving IVIF Gamma Globulin every 3 weeks. I hydrate heavily for 2 days before and 2 days after to help with headache side effects. Before the infusion I am given orally, Benedryl for possible rash side effects, and Tylenol for headache. My infusion is done slowly, taking approximately 5-6 hours as to hopefully prevent side effects. I commonly have fatigue for the next few days and sleep as needed. But I also have fibromyalgia and other chronic pain issues .
Hoping you will get some help soon. God bless you.
