COMMENT:
Indeed. All the antibiotics in the penicillin and cephalosporin class
(of which Keflex/cephalexin is one) have the beta-lactam ring nucleus,
which contains a sulfur atom. Breakdown products and impurities, even
in new and well manufactured pills, lead to that sulfury smell. It's
especially apparent in tablets (ie Pen VK) and capsules (like your
Keflex), and not so bad in the film coated more-expensive members of
the class like Ceftin (though you can still detect it in cut pills). So
you'll smell a trace of sulfur in the drug itself, and if not, you'll
certainly smell it after it's passed through your gut.
