Several medical agents have some efficacy against visceral or cutaneous leishmaniasis, however, a 2005 survey concluded that miltefosine is the only effective oral treatment for both forms of leishmaniasis.

Pregnancy and breastfeeding

Miltefosine is listed as pregnancy category D by the FDA. This means there is evidence-based adverse reaction data from investigational or marketing experience or studies in humans of harm to the human fetus.

, which occur in 60% of people. Other common side effects are dizziness, headache, and daytime sleepiness. Serious side effects include rash, diarrhea, and arthritis. The side effects are more severe in women and young children. The overall effects are quite mild and easily reversed.

Mechanism of action

Miltefosine primarily acts on ''Leishmania'' by affecting the species's promastigote and amastigote stages. Miltefosine exerts its activity by interacting with lipids, inhibiting cytochrome c oxidase and causing apoptosis-like cell death. This may affect membrane integrity and mitochondrial function of the parasite.
