It is designated (±)-N-methyl-3-phenyl-3-[(a,a,a-trifluoro-p-tolyl)-oxy]propylamine hydrochloride and has the empirical formula of C17H18F3NO•HCl. Its molecular weight is 345.79.... Each Prozac Pulvule contains fluoxetine hydrochloride equivalent to 10 mg (32.3 mmol) or 20 mg (64.7 mmol) of fluoxetine. Unquote It is administered orally. It is the main ingredient in Prozac. Just having CL or F in a chemical does not mean it is harmful. Salt, NaCl is essential for life and most of us brush and usually swallow a little Fl every morning. HCl is resident in every one of our stomachs. I cannot find it as an ingredient of Apistan. If it is, and since it is an antidepressant (prozac), maybe that is why beekeepers and their Apistan treated bees are so cheerful. Bill Truesdell Bath, ME
