Medical treatment that effectively rids the body of a specific parasite depends on the type of parasite, and not all parasitic infections can be treated. Antibiotics and other drugs, such as Melarsopro or Nifurtimox, may be used, according to the Centers for Disease Control and Prevention and Healthline.
A physician chooses the most effective drug to treat a parasite infection once he determines the exact organism that is causing the infection. In some cases, an antidiarrheal medication may be prescribed because most parasite infections produce gastrointestinal symptoms, according to Healthline. Patients may need to take medication only once or up to several weeks to clear the infection, and medications may not work properly if not taken as prescribed.
Medical treatment for parasites can involve tests such as the examination of fecal matter, a scotch tape test to collect and identify parasitic eggs, or even a barium X-ray to diagnose more serious problems caused by a parasitic infection. Medical treatment for parasites also involves retesting to ensure that the body is free of the parasite after completing the treatment period. Conventional medical treatments for parasitic infections are believed to rid the body of parasites more quickly and effectively than alternative therapies, and they produce fewer negative side effects, according to the University of Maryland Medical Center.
