Possibly; take more : Quoting ronald hoffman md "b12 is also central to immune processes because it governs cell division and growth. Without adequate b12, white blood cells can't mature and multiply." (http://www.Drhoffman.Com/page.Cfm/125) my favorite remedy for colds is pelargonium sidoides, widely sold as umcka. Monthly B12 shots maintain a normal level but i advise doing them 2-3x/wk til your level reaches 600!

No: This will not make your cold last longer. See your physician for recommendations and evaluation.
