Colloidal silver is a mineral. Despite promoters' claims, silver has no known function in the body and is not an essential mineral supplement. Colloidal silver products were once available as over-the-counter drug products. In 1999 the U.S. Food and Drug Administration (FDA) ruled that these colloidal silver products were not considered safe or effective. Colloidal silver products marketed for medical purposes or promoted for unproven uses are now considered "misbranded" under the law without appropriate FDA approval as a new drug. There are currently no FDA-approved over-the-counter or prescription drugs containing silver that are taken by mouth. However, there are still colloidal silver products being sold as homeopathic remedies and dietary supplements.
There are many Internet ads for the parts of a generator that produces colloidal silver at home. People who produce colloidal silver at home will likely not be able to evaluate their product for purity or strength. There are many products that are far safer and more effective than colloidal silver.
Despite these concerns about safety and effectiveness, people still buy colloidal silver as a dietary supplement and use it for a wide range of ailments.
People are using colloidal silver for conditions such as infections, cancer, diabetes, arthritis, and many others, but there is no scientific evidence to support these uses. Using colloidal silver can also be unsafe.
How it works
Colloidal silver can kill certain germs by binding to and destroying proteins.
Possibly IneffectiveEye infections
Some research shows that using colloidal silver eye drops in both eyes shortly after birth does not help prevent certain eye infections in newborns. Other research shows that applying a colloidal silver solution to the eye surface of people undergoing eye surgery does not prevent infections as well as applying povidone-iodine solution.
Colloidal silver is LIKELY UNSAFE when taken by mouth, applied to the skin, or injected intravenously (by IV). The silver in colloidal silver products gets deposited in vital organs such as the skin, liver, spleen, kidney, muscle, and brain. This can lead to an irreversible bluish skin discoloration that first appears in the gums. It can also stimulate melanin production in skin, and areas exposed to the sun will become increasingly discolored.
Pregnancy and breast-feeding: Colloidal silver isLIKELY UNSAFEwhen taken by mouth, applied to the skin or injected intravenously (by IV). Increased silver levels inpregnantwomen have been linked toabnormaldevelopmentof theear, face, andneckin their babies. Colloidal silver supplements can also lead to silver accumulation in the body, which can lead to an irreversible bluish skin discoloration known asargyria. Silver can also be deposited in vital organs, where it does serious damage.
Colloidal silver might decrease how much antibiotic the body absorbs. Taking colloidal silver along with antibiotics might decrease the effectiveness of some antibiotics.Some antibiotics that might interact with colloidal silver include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar).Colloidal silver might decrease how much tetracycline antibiotics the body can absorb. Taking colloidal silver with tetracycline antibiotics might decrease the effectiveness of tetracycline antibiotics. To avoid this interaction take colloidal silver two hours before or four hours after taking tetracyclines.Some tetracyclines include demeclocycline (Declomycin), minocycline (Minocin), and tetracycline (Achromycin).Colloidal silver might decrease how much levothyroxine the body absorbs. Taking levothyroxine along with colloidal silver might decrease the effectiveness of levothyroxine.Medications that can harm the liver (Hepatotoxic drugs)
Colloidal silver might harm the liver. Taking colloidal silver along with medications that might also harm the liver can increase the risk of liver damage. Do not take colloidal silver if you are taking a medication that can harm the liver. Some medications that can harm the liver include acetaminophen (Tylenol and others), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), fluconazole (Diflucan), itraconazole (Sporanox), erythromycin (Erythrocin, Ilosone, others), phenytoin (Dilantin), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and many others.Penicillamine (Cuprimine, Depen)
Penicillamine is used for Wilson's disease and rheumatoid arthritis. Colloidal silver might decrease how much penicillamine your body absorbs. This might decrease the effects of penicillamine.
