The warning originated from the National Center for Complementary and Alternative Medicine (NCCAM), a part of the NIH. See:
http://nccam.nih.gov/health/alerts/silver/ "Colloidal silver may interfere with the body's absorption of the following drugs: penacillamine, quinolones, tetracyclines, and thyroxine." There is no basis for the warning provided. If anyone can provide data that SHOWS that colloidal silver interferes with ANY antibiotic, I would be very interested to see it. But as it is, anyone can make any unsubstantiated charge against CS and it is expected that CS uses must disprove the claim. Hey, believe whatever you want! Meanwhile here is a couple more. - Steve N Here is a study that shows that CS increases the bactericidal efficiency of amoxicillin Synergistic antibacterial effects of β-lactam antibiotic combined with silver nanoparticles http://www.iop.org/EJ/abstract/0957-4484/16/9/082 "When amoxicillin and silver nanoparticles are combined, it results in greater bactericidal efficiency on Escherichia coli cells than when they were applied separately. Dynamic tests on bacterial growth indicated that exponential and stationary phases are greatly decreased and delayed in the synergistic effect of amoxicillin and silver nanoparticles. In addition, the effect induced by a preincubation with silver nanoparticles is examined. The results show that solutions with more silver nanoparticles have better antimicrobial effects. And: http://www.academicjournals.org/sre/PDF/pdf2008/May/Iroha%20et%20al%20.pdf " Unlike pharmaceutical antibiotics, which destroy beneficial enzymes, colloidal silver leaves these beneficial enzymes intact (Hall et al., 1999). An added advantage to the use of silver is that it has variously been shown to have high safety profile in vivo and cannot interact or interfere with other medicines being taken (Iroha et al., 2007). Furthermore, it is known not to destroy the normal microbial flora of the gut thereby avoiding the negative effects of traditional antibiotics that kill good bacteria in the lower digestive tract (Beaker and Spadaro, 1981)."

Also, interaction studies between colloidal silver and some conventional antibiotics were carried out against the clinical isolates of Escherichia coli and S. aureus using disc diffusion technique. The result of the study shows that the test organisms were sensitive to the colloidal silver at both concentrations and also to some of the antibiotics in the paper disc. The killing rate studies revealed that the colloidal silver is highly bactericidal against the test isolates at both concentrations. The drug interaction study showed no antagonism, indicating that concomitant use of colloidal silver with these antibiotics may not affect the therapeutic efficacy of either of these agents."
