However Chloroquine or hydroxychloroquine is taken once a week, beginning at least 1 week before entering a chloroquine-sensitive malaria-endemic region (or 2-3 weeks before to assess tolerability), during the period of exposure, and for 4 weeks after leaving the malaria-endemic region
The volume of distribution of these medications is very high and potentially worrying for pregnant women and their half-lives are long; 10 to 30 days for chloroquine and 30 to 60 days for hydroxychloroquine, which leads to prolonged exposure after stopping these drugs
But the hyclate salt's adverse effects combined with the capsule's galenic form are incompatible with good chemoprophylaxis compliance
