Reinitiate primary prophylaxis if CD4+ T-cell count decreases to <200/mm3.199
50 mg once weekly used in conjunction with oral leucovorin (25 mg once weekly) and oral dapsone (50 mg once daily).199 203 214 Alternatively, 75 mg once weekly used in conjunction with oral leucovorin (25 mg once weekly) and oral dapsone (200 mg once weekly).199 203 214
Initiate long-term suppressive therapy or chronic maintenance therapy (secondary prophylaxis) to prevent recurrence in those with a history of PCP.199 214
Discontinuance of secondary prophylaxis is recommended in those who have a sustained (3 months or longer) increase in CD4+ T-cell counts to >200/mm3199 214 since such prophylaxis appears to add little benefit in terms of disease prevention and discontinuance reduces medication burden, potential for toxicity, drug interactions, selection of drug-resistant pathogens, and cost.199
Reinitiate secondary prophylaxis if CD4+ T-cell count decreases to <200/mm3 or if PCP recurs at a CD4+ T-cell count >200/mm3.199 214 It probably is prudent to continue secondary prophylaxis for life in those who had PCP episodes when they had CD4+ T-cell counts >200/mm3.199
Manufacturer recommends 50–75 mg once daily in conjunction with a sulfonamide for 1–3 weeks; reduce dosage of both drugs by 50% and continue for 4–5 additional weeks.167
200 mg once, then 50 mg once daily in those weighing <60 kg or 75 mg once daily in those weighing ≥60 kg; used in conjunction with oral leucovorin (at least 10–20 mg once daily) and oral sulfadiazine (1 g every 6 hours in those weighing <60 kg or 1.5 g every 6 hours in those weighing ≥60 kg).214
Alternatively, 200 mg once daily, then 50 mg once daily in those weighing <60 kg or 75 mg once daily in those weighing ≥60 kg; used in conjunction with oral leucovorin (at least 10–20 mg once daily) and either oral or IV clindamycin (600 mg every 6 hours), oral atovaquone (1.5 g twice daily), or oral azithromycin (0.9–1.2 g once daily).214
Continue acute treatment for ≥6 weeks; a longer duration may be appropriate if disease is extensive or response incomplete at 6 weeks.214
50 mg once weekly used in conjunction with oral leucovorin (25 mg once weekly) and oral dapsone (50 mg once daily).199 Alternatively, 75 mg once weekly used in conjunction with oral leucovorin (25 mg once weekly) and oral dapsone (200 mg once weekly).199
Alternatively, 25 mg once daily used in conjunction with oral leucovorin (10 mg once daily) and oral atovaquone (1.5 g once daily).199
Discontinuance of primary toxoplasmosis prophylaxis is recommended in HIV-infected adults and adolescents who have a sustained (3 months or longer) increase in CD4+ T-cell counts to >200/ mm3 since such prophylaxis appears to add little benefit in terms of disease prevention and discontinuance reduces medication burden, potential for toxicity, drug interactions, selection of drug-resistant pathogens, and cost.199
Reinitiate primary prophylaxis if CD4+ T-cell count decreases to <100–200/mm3.199
25–50 mg once daily in conjunction with oral leucovorin (10–25 mg once daily) and either oral sulfadiazine (0.5–1 g every 6 hours) or, alternatively, oral clindamycin (300–450 mg every 6–8 hours).199 214
Alternatively, 25 mg once daily with oral leucovorin (10 mg once daily) and oral atovaquone (750 mg every 6–12 hours).199 214
Initiate long-term suppressive therapy or chronic maintenance therapy (secondary prophylaxis) in all patients who have completed initial treatment of toxoplasmosis encephalitis (TE).199 214
Consideration can be given to discontinuing secondary prophylaxis in adults or adolescents who successfully completed initial treatment for TE, are asymptomatic with respect to TE, and have a sustained (6 months or longer) increase in CD4+ T-cell counts to >200/mm3.199 214
Reinitiate secondary prophylaxis if CD4+ T-cell count decreases to <200/mm3.199 214
50–75 mg once daily or in divided doses with oral leucovorin (5–10 mg) once daily.203 214
Maximum 25–50 mg per dose.215

High pyrimethamine dosage may deplete folic acid stores and cause reversible bone marrow depression.167 Use with caution in patients with possible folate deficiency, including malabsorption syndrome, alcoholism, pregnancy (see Pregnancy under Cautions), and in those receiving drugs affecting folate levels (see Interactions).167 Hematologic effects may also occur with lower pyrimethamine dosages in certain individuals.167 Reduce or discontinue pyrimethamine or Fansidar if signs of folic or folinic acid deficiency occur.167 168 Perform CBCs twice weekly.167 (See Laboratory Monitoring under Cautions.)
Pyrimethamine dosage used for treatment of toxoplasmosis approaches toxic levels and is associated with adverse effects resulting from folic acid deficiency.167 a Megaloblastic anemia, leukopenia, thrombocytopenia, and pancytopenia reported.167 When pyrimethamine is used for treatment of toxoplasmosis, give leucovorin (folinic acid) concomitantly.167 203 (See Toxoplasmosis under Pediatric Patients and also under Adults, in Dosage and Administration.) Adverse hematologic effects, including megaloblastic anemia, generally reversible when drug discontinued.a
Leukopenia (generally mild and reversible) reported when Fansidar administered for ≥2 months for malaria prevention.168
Manufacturer states pyrimethamine may be carcinogenic.167 Chronic granulocytic leukemia and reticulum cell sarcoma reported rarely after long-term use for treatment of toxoplasmosis; increase in lung tumors reported in animal study.167
Fatalities due to erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis reported with Fansidar.110 111 112 114 132 136 139 140 143 144 145 159 168 Other hypersensitivity reactions, including serum-sickness reactions,168 vasculitis (cutaneous or generalized),140 urticaria,168 pruritus,140 168 exfoliative dermatitis,132 168 and photosensitivity,140 168 also reported.

Use Fansidar with caution in patients with severe allergy or bronchial asthma.168
Avoid excessive sun exposure when taking Fansidar.168
Discontinue at first sign of rash, sore throat, fever, arthralgia, cough, shortness of breath, pallor, jaundice, or glossitis.167 168
Pyrimethamine and Fansidar are not included in current CDC recommendations for prevention or treatment of malaria.b c Consider that resistance to pyrimethamine is prevalent worldwide167 and resistance to Fansidar is widespread in certain areas.203 b (See Malaria under Uses.)
Do not use Fansidar for treatment of severe malaria.168 Has not been evaluated for treatment of cerebral malaria or other severe manifestations of complicated malaria, including hyperparasitemia, pulmonary edema, or renal failure.168 Patients with severe malaria are not candidates for oral therapy.168
If recrudescent P. falciparum infections occur after treatment with Fansidar or if prophylaxis with the drug fails, use a different blood schizonticide.168
Hemolysis may occur if Fansidar is used in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency.168 e
Renal failure, hematuria, interstitial nephritis, elevated BUN and serum creatinine, toxic nephrosis with oliguria and anuria, and crystalluria reported in patients receiving a sulfonamide or pyrimethamine.167 168
Fansidar contains a sulfonamide and shares the toxic potentials of the sulfonamides.168 Sulfonamides have been associated with renal toxicity manifested by renal colic, nephritis, urolithiasis, toxic nephrosis with anuria and oliguria, hematuria, proteinuria, crystalluria, kidney stone formation, and elevation of BUN and serum creatinine concentrations.e Nephritis and hemolytic-uremic syndrome also reported.e
Adverse renal effects usually are the result of crystalluria.e Risk of crystalluria may be decreased by maintaining an adequate urinary output and by increasing urinary pH.e Unless the urine is highly acidic and/or the drug is relatively insoluble, alkalinization of the urine usually is not necessary if urinary output is maintained at a minimum of 1.5 L daily.e
Perform urinalysis and assess kidney function frequently during sulfonamide therapy.e Perform urinalysis (including microscopic examination) and renal function tests when Fansidar is used in patients with impaired renal function.168 (See Laboratory Monitoring under Cautions.) Maintain adequate fluid intake to minimize risk of crystalluria and stone formation.168 e
If persistent, heavy crystalluria, hematuria, or oliguria occurs, sulfonamide therapy should be discontinued and alkali therapy maintained.e
Abnormal liver function test results (e.g., elevated serum ALT, AST, alkaline phosphatase, and bilirubin concentrations),132 140 141 142 jaundice,113 114 132 140 142 hepatomegaly,132 and hepatitis,132 142 168 sometimes fatal,132 reported with Fansidar.
Adverse hepatic effects have been associated with severe cutaneous reactions to Fansidar.112 132 (See Dermatologic and Hypersensitivity Reactions under Cautions.)
Adverse GI effects (anorexia, abdominal cramps, vomiting, atrophic glossitis, gastritis)167 may occur with high pyrimethamine dosage.167 Administration with a meal may reduce anorexia and vomiting.167
Ataxia, tremors, seizures, and respiratory failure reported with high pyrimethamine dosage.a Headache, light-headedness, insomnia, depression, malaise, fatigue, and irritability also reported rarely.a
In patients with seizure disorders being treated for toxoplasmosis, use low initial pyrimethamine dosage to avoid potential nervous system toxicity.167
Reversible hyperesthesia reported rarely with Fansidar.140
Monitor CBC, including platelet counts, twice weekly in patients receiving high pyrimethamine dosage.167
If Fansidar is used for >3 months, regularly monitor liver enzyme tests, CBCs, and urinalysis for crystalluria.168 If used in patients with impaired renal function, monitor renal function and regularly perform urinalysis (including microscopic examination).168
When pyrimethamine is used in fixed combination with sulfadoxine, consider the cautions, precautions, and contraindications associated with sulfadoxine.168
Category C.167 168
Fansidar contraindicated for malaria prophylaxis in pregnant women at term.168
Use pyrimethamine or Fansidar during pregnancy only when potential benefits outweigh possible risks;167 168 if pyrimethamine is used to treat toxoplasmosis during pregnancy, administer leucovorin concurrently to decrease hematologic toxicity.167 197
Women of childbearing potential should use effective contraceptive measures while receiving pyrimethamine or Fansidar;167 168 avoid pregnancy for 3 months following the last dose of the fixed combination.168
