Drug-Drug interactionMay ↓ absorption and effectiveness of oral hormonal contraceptives..
Oral (Adults and adolescents ≥45 kg) 50 mg three times daily for 28 consecutive days.
Oral (Adults and adolescents 30–44 kg) 50 mg twice daily for 28 consecutive days.

- Assess visible lesions periodically during therapy.
- Monitor for vomiting and diarrhea. Encourage fluid intake to avoid dehydration.
- Lab Test Considerations: Obtain a negative urine pregnancy test prior to beginning therapy.
- Monitor renal function weekly and for 4 wks after completion of therapy. May ↑ serum creatinine.
- Monitor AST, ALT, and serum bilirubin periodically during therapy. May cause ↑ in AST, ALT, and bilirubin.
- Monitor platelet count periodically during therapy. May cause thrombocytopenia and agranulocytosis.
Potential Nursing DiagnosesImpaired skin integrity (Indications)
Deficient knowledge, related to disease process and medication regimen (Patient/Family Teaching)
- Administer with food to decrease GI side effects for 28 consecutive days. Swallow capsule whole; do not open, dissolve or chew.
- Instruct patient to take miltefosine as directed for 28 consecutive days. Advise patient to read the Medication Guide before beginning therapy and with each Rx refill in case of changes.
- Advise patient to notify health care professional immediately if skin rash with blisters occurs. Discontinue therapy if exfoliative or bullous rash occurs.
- May cause dizziness and drowsiness. Caution patient to avoid driving and other activities requiring alertness until response t medication is known.
- Instruct patient to notify healthcare professional if abdominal pain, nausea, vomiting, or diarrhea are persistent or severe. Advise to maintain hydration to prevent kidney damage.
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications.
- Caution patient that miltefosine may cause teratogenic effects during pregnancy and may impair fertility. Advise female patient to use effective contraception during and for at least 5 mo after completion of therapy. Nausea and vomiting may decrease absorption of hormonal contraceptives. Advise patient to use a non-hormonal or alternative method of effective contraception. May cause scrotal pain and decreased or absent ejaculation in males. Advise females to avoid breastfeeding during and for at least 5 mo after completion of therapy.
- Resolution of signs and symptoms of leishmaniasis.

miltefosineAn oral alkyl phosphocholine analogue used to treat cutaneous and visceral leishmaniasis.
Nausea, vomiting, diarrhoea, rigors, increased transaminases, grade-III hepatotoxicity and renal damage.
Miltefosine interferes with cell-signalling pathways and membrane synthesis of Leishmania donovani and L infantum, as well as with mitogenic signal transduction; it also induces apoptosis. It has been used in treating HIV disease because miltefosine inhibits the PI3K/Akt pathway, removing HIV-infected macrophages from circulation without affecting normal cells.
