I know this drug is used for HIV/AIDS, but what other diseases, or
symptoms is it prescribed for?

Hi Sootie,

    I beleive you are referring to Metronidazole (Flagyl)
"DRUG CLASS AND MECHANISM: Metronidazole is an antibiotic effective
against anaerobic bacteria and certain parasites. Anaerobic bacteria
are single-cell living organisms that thrive in low oxygen
environments and can cause disease in the abdomen (bacterial
peritonitis) liver (liver abscess), and pelvis ( abscess of the
ovaries and the fallopian tubes). Giardia lamblia and ameba are
parasites that can cause abdominal pain and chronic diarrhea in
infected individuals. Metronidazole selectively blocks some of the
cell functions in these microorganisms, resulting in their demise."

"Metronidazole is used to treat giardia infections of the small
intestines, amebic liver abscess and dysentery (amebic colon infection
causing bloody diarrhea), trichomonas vaginal infections, and carriers
of trichomonas (both sexual partners) who do not have symptoms of
infection. Metronidazole is also used alone or in combination with
other antibiotics in treating abscesses in the liver, pelvis, abdomen
and brain caused by susceptible anaerobic bacteria. Metronidazole is
also used in treating colon infection caused by a bacteria called C.
difficile. Many commonly used antibiotics can alter the normal type of
bacteria that inhabit the colon. C. difficile is an anaerobic bacteria
that can infect the colon when the normal bacteria types of the colon
are altered by common antibiotics. This leads to inflammation of the
colon (pseudomembranous colitis) with severe diarrhea and abdominal
pain."

Wikipedia has information also:

  This drug may be given to HIV patients, who are highly prone to
infections,(Or ANY patient) to treat an infection, but it is not an
HIV specific drug.


  I just answered a long question on HIV drugs, and there is no drug
with the name "Methonidazole". You may want to peruse the answer found
here:

Hope this has helped. Please ask for an Answer Clarification, if any
thing is unclear. I will be glad to assist further, if possible,
before you rate.

You wouldn't happen to mean metronidazole, an antiprotozoal and
antibacterial commonly used against anaerobic bacteria and certain
parasites like giardia?

"Methonidazole" is  not known as an HIV or AIDS drug. The only
reference I could find to "methonidazole" is a quotation in the IRIN
News,  news service for Africa:

"Sitting with her friends in the shade of the tree, Fatima, a plump
24-year-old woman from Niger, said she had stopped going to the
hospital altogether.

"'We noticed that they always gave us the same stuff?cotrimedazole,
methonidazole and jantamycine,'" Fatima said, reeling off a list of
treatments for venereal disease.

It is unlikely that "methonidazole" is even used in the treatment of
veneral disease, and that the article may contain misinformation.

See, I suspect the drugs from the above quote are gentamicin,
clotrimazole, and metronidazole, all of which could be used for
vaginal problems.
