IVIG Loading

    • June 6, 2017 at 7:39 pm

      Anyone start IVIG slowly? I know loading dose is the norm, but I am wondering if anyone has any experience slowly ramping up. I have started with a very small dose with a plan to get to 30g bi weekly. I weigh 68kg. I am ok with not rocking the boat as I have had a long 2 years of trial and error with drugs and I have become hypersensitive to them, admittedly psychosomatic.
      My symptoms are mild but the standards of this forum. Primarily sensory with significant balance issues and very easy to fatigue. I can’t say as its weakness per se, just significant stamina issues. I could complete a full workout with squats last year and this year a walk around the neighborhood produces major twitching, burning, dead no feeling, and fatigue for 2+ days.
      Thanks again for the help. I am a newcomer but I have searched the threads for any advice in the matter.

      I was prescribed a very typical protocol of 2g/kg over 4 days, then 1g/kg every 4 weeks. Perhaps ask your doctor why s/he chose this regimen for you.

      Thanks for the reply. He started with a test dose of 5mg. I had a major headache so he wanted to move carefully which I am glad for. I have had major crippling fatigue since my last 10g infusion on monday. It crept up on me, I felt pretty good the day after and now I am barely functioning and scared to death.
      I find fatigue to be common on these sites but not of this severity and after such a small infusion.

      Something amiss with the math. 2g per kg. If you weighed 50kg, it is about 110 lbs. Therefore, for a 110 lb person, the ‘standard’ loading dose would be 100g. You say you got 5mg. 5mg= .005g

      Somebody else help with the math, that is 100/.005 or 1/20,000 of a normal dose. nu uh. Something amiss if that little bit gave you a major headache.

      Even a 10g dose is 1/10th the normal loading dose. Ask your doctor about infusion rates, how long does it take to get your infusion?

      Thank you for your reply.
      I did start with a 5g dose. My understanding was that this was a test dose as I started with home infusion. I had a significant headache during and afterwards. I have been struggling with my health and trying to start a new job, I think the majority of my headaches are stress related. I was then to try 30g weekly. I had such a hard time with the 5g – combined with trying to stay employed – that my Neuro suggested 10g a week. I don’t know whats going on at this point. I am wiped out – I mean wiped out for 3-5 days after a 10g infusion. I have a very high tolerance for pain, have gone years with this pain with no meds, but this fatigue scared me. I am grasping to being an employed father and just scared to lose that grasp.

      Benadryl and Tylenol taken before IVIg can help mitigate headaches.

      I’ve found if the IVIg is infused too fast, it makes me tired/fatigued for a couple days after the treatment. We tried a slower rate and I felt great afterwards.

      Not sure that what you received is enough to do the job. I’d try the full dosage at a slower rate before you give up on IVIg.

      Thanks for replying. Yes at this point I really need to give IVIG a full trial. I do not have alot of other options and my legs are really getting weaker. I fit the mold to a T symptom wise, diagnostics are less compliant.
      I am going to get with my neuro and ask why he chose a weekly regimen versus a higher loading dose. He is very well written and was the chief of a department at one time.
      The headaches dont scare me like they did, just the fatigue. Wow that knocked me down for several days. Scared me.

      Thanks again

      jk, I think the standard 2g/kg is for total loading dose which is administered over a few days. Five is typical, which was my regimen. So for your hypothetical 110 lb person, that would be 20g/day for five days. If Ryan’s dose was 5g in one day (not 5mg), then that would be 1/4 of a normal dose, which seems more reasonable as a test to determine tolerance of the treatment.

      In my case, I was just given the standard dose over five consecutive days and had no problems with it. I don’t remember the infusion rate, but since I was in hospital there was plenty of time. It was a few hours per day.
