Advice should be individually optimized to achieve a high degree of protection and compliance. Individual risk assessment takes into consideration the duration of stay in the endemic area, the individual exposure, the seasonal transmission rates, and the drug-resistance situation.

Food and Drug Administration FDA for malaria prophylaxis and are currently available by prescription chloroquine, primaquine, mefloquine, doxycycline, atovaquone/proguanil A/P, and tafenoquine. The concurrent and short-term adverse events for users taking these drugs are well documented.

Aralen, Chloroquine phosphate chloroquine dosing.. Long-term prophylaxis with weekly mefloquine. Abstract. An historical prospective study was performed on 5120 Italian soldiers deployed in Somalia and Mozambique in 1992–1994, to determine compliance and tolerability of long-term malaria chemoprophylaxis with chloroquine plus proguanil C + P and with mefloquine. These patients are also at risk of developing chloroquine retinopathy. Irreversible visual impairment resulting from accumulation of chloroquine in the retina is a recognized complication of long-term, high-dosage therapy. Total lifetime exposure to chloroquine should not exceed 100g of the base. LONG-TERM EFFECTS OF ANTIMALARIAL DRUGS Concurrent Adverse Events The dosing regimens for prophylaxis and treatment vary significantly, and, as with other drugs of interest, individuals using chloroquine for malaria treatment are exposed to a larger dose in a shorter period of time than those using it for malaria prophylaxis.
