Miltefosine is an oral medication that is used to treat certain types of parasitic infections, including leishmaniasis and Acanthamoeba keratitis. It works by interfering with the growth and reproduction of the parasites, and can help to reduce the severity and duration of infection.

In the case of Acanthamoeba keratitis, miltefosine is typically used in combination with other medications, such as chlorhexidine and propamidine, to help eradicate the amoeba and prevent further damage to the eye.

Miltefosine is generally well-tolerated, but can cause side effects such as nausea, vomiting, diarrhea, and liver problems. It should not be used during pregnancy or breastfeeding, as it can cause harm to the developing fetus or infant.

Miltefosine is not effective against all types of parasitic infections, and should only be used under the guidance of a healthcare professional who is familiar with the diagnosis and treatment of these conditions.
