Treatment of Malaria

  • Atovaquone and proguanil hydrochloride tabletsare indicated for the treatment of acute, uncomplicated P. falciparum malaria. Atovaquone and proguanil hydrochloride tablets have been shown to be effective in regions where the drugs chloroquine, halofantrine, mefloquine, and amodiaquine may have unacceptable failure rates,

presumably due to drug resistance.

Dosage

  • The daily dose should be taken at the same time each day with food or a milky drink. In the event of vomiting within 1 hour after dosing, a repeat dose should be taken.

Prevention of Malaria

  • Start prophylactic treatment withatovaquone and proguanil hydrochloride tablets 1 or 2 days before entering a malaria-endemic area and continue daily during the stay and for 7 days after return.
  • Adults: One atovaquone and proguanil hydrochloride tablet(adult strength = 250 mg atovaquone/100 mg proguanil hydrochloride) per day.

Treatment of Acute Malaria

  • Adults: Fouratovaquone and proguanil hydrochloride tablets(adult strength; total daily dose 1 g atovaquone/400 mg proguanil hydrochloride) as a single daily dose for 3 consecutive day.

Renal Impairment

  • Do not useatovaquone and proguanil hydrochloride tablets for malaria prophylaxis in patients with severe renal impairment (creatinine clearance <30 mL/min). Use with caution for the treatment of malaria in patients with severe renal impairment, only if the benefits of the 3 day treatment regimen outweigh the potential risks associated with increased drug exposure. No dosage adjustments are needed in patients with mild (creatinine clearance 50 to 80 mL/min) or moderate (creatinine clearance 30 to 50 mL/min) renal impairment.

DOSAGE FORMS AND STRENGTHS

Contraindications

Hypersensitivity

Severe Renal Impairment

  • Atovaquone and proguanil hydrochloride is contraindicated for prophylaxis of P. falciparum malaria in patients with severe renal impairment (creatinine clearance <30 mL/min) because of pancytopenia in patients with severe renal impairment treated with proguanil.

Warnings

Vomiting and Diarrhea

  • Absorption of atovaquone may be reduced in patients with diarrhea or vomiting. If atovaquone and proguanil hydrochloride is used in patients who are vomiting, parasitemia should be closely monitored and the use of an antiemetic considered. [See Dosage and Administration (2).] Vomiting occurred in up to 19% of pediatric patients given treatment doses of atovaquone and proguanil hydrochloride. In the controlled clinical trials, 15.3% of adults received an antiemetic when they received atovaquone/proguanil and 98.3% of these patients were successfully treated. In patients with severe or persistent diarrhea or vomiting, alternative antimalarial therapy may be required.

Relapse of Infection

  • In mixed P. falciparum and Plasmodium vivax infections, P. vivax parasite relapse occurred commonly when patients were treated with atovaquone and proguanil hydrochloride alone.
  • In the event of recrudescent P. falciparum infections after treatment with atovaquone and proguanil hydrochloride or failure of chemoprophylaxis with atovaquone and proguanil hydrochloride, patients should be treated with a different blood schizonticide.

Hepatotoxicity

  • Elevated liver laboratory tests and cases of hepatitis and hepatic failure requiring liver transplantation have been reported with prophylactic use of atovaquone and proguanil hydrochloride.

Severe or Complicated Malaria

  • Atovaquone and proguanil hydrochloride has not been evaluated for the treatment of cerebral malaria or other severe manifestations of complicated malaria, including hyperparasitemia, pulmonary edema, or renal failure. Patients with severe malaria are not candidates for oral therapy
