chloroquine - oral, Aralen (cont.)
HOW TO USE: Take this medication by mouth, usually with food to prevent stomach upset, exactly as directed by your doctor. Daily or weekly dosing, dosage amount, and length of treatment are based on your medical condition, on whether you are preventing or treating the illness, and your response to treatment. The dosage in children is also based on weight.To prevent malaria, take chloroquine once weekly on the same day each week, or as directed by your doctor. Start this medication usually 1 to 2 weeks before you enter the malarious area, continue to take it weekly while in the area, and weekly for 4 to 8 weeks after leaving the area, or as directed by your doctor. Mark your calendar or travel schedule with a reminder to help you remember.To treat malaria infection or an ameba infection, follow your doctor's instructions.Take this medication 4 hours before or after taking a certain drug for diarrhea (kaolin) or taking antacids (such as magnesium/aluminum hydroxide). These products may bind with chloroquine, preventing your body from fully absorbing the drug.It is very important to continue taking this medication exactly as prescribed by your doctor. Do not take more or less of this drug than prescribed. Do not stop taking it before completing treatment, even if you feel better, unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause prevention/treatment to be ineffective, cause the amount of parasite to increase, make the infection more difficult to treat (resistant), or worsen side effects.It is important to prevent mosquito bites (such as by using appropriate insect repellents, wearing clothes that cover most of the body, remaining in air-conditioned or well-screened areas, using mosquito nets and insect-killing spray). Buy insect repellent before traveling. The most effective insect repellents contain diethyltoluamide (DEET). Ask your doctor or pharmacist to recommend the appropriate strengths of mosquito repellent for you/your children.No drug treatment is completely effective in preventing malaria. Therefore, seek immediate medical attention if you develop symptoms of malaria (such as fever, chills, headache, other flu-like symptoms), especially while in the malarious area and for 2 months after completing this prescription. Quick treatment of malaria infection is needed to prevent serious, possibly fatal, outcomes.When using chloroquine for treatment of malaria, tell your doctor if your condition persists or worsens.
