Most infections are
asymptomatic. Heavy infections can cause gastrointestinal problems
(abdominal pain, diarrhea, anorexia), headache, fatigue, anemia and
identification of eggs in feces is evidence of infection. Because eggs may
be difficult to find in light infections, a concentration or flotation
procedure is recommended. Patients may have co-infections with
hookworm, so care must be taken to differentiate the two.
Pyrantel pamoate is
the drug of choice; alternatives include mebendazole and albendazole. For additional
information, see the recommendations in
The Medical Letter
(Drugs for Parasitic Infections).
