Reply To: Cold/Virus before IVIG

Plasma Exchange would remove the antibiotics from his system, but he’s not doing that. IVIg adds to what’s already in his system, so the antibiotics will still be able to work.

The regular prophylactic use of antibiotics should be avoided because of an increased risk of infection with fungi or other resistant organisms. In other words, I would try to wait on taking the Z-pak until after the IVIg treatments. The IVIg alone may be enough to help cure the cold. Plus the FDA has a warning out that Z-Paks pose a heart risk.

The other potential issue has to do with the brand of IVIg being administered. Some brands may interact poorly with a Z-pak.
