To treat malaria in adults, Aralen is taken twice a day for one day and then once a day for two more days. For children, the dose of Aralen will depend on the child's weight. This medication should be taken with food in order to prevent an upset stomach. Even if you feel better earlier than expected, make sure to finish your prescribed amount.
An Introduction to Dosing With AralenThe dose of Aralen® (chloroquine phosphate) your healthcare provider recommends will vary, depending on a number of factors, including:
- The reason you are taking Aralen
- Other medical conditions you may have
- Your weight.
As is always the case, do not adjust your dosage of Aralen unless your healthcare provider specifically tells you to do so.
What Is the Aralen Dosage for Preventing Malaria?The usual dose for malaria prevention in adults is 500 mg once a week. The Aralen dosage in children is based on the child's weight. Children receive about 8.3 mg per kg of body weight (about 3.8 mg per pound of body weight) or the adult dose, whichever is less.
Treatment usually begins two weeks before traveling to an area where you might get malaria, continues weekly while you are in the malaria area, and for eight weeks after leaving the area.
If treatment does not begin two weeks prior to travel, an initial larger dose (called a "loading dose") is given instead. In adults, the loading dosage of Aralen is 1000 mg. In children, the loading dose is about 16.7 mg per kg of body weight (about 7.6 mg per pound of body weight), which can be divided into two doses taken six hours apart.
What Is the Aralen Dosage for Treating Malaria?The standard dose of Aralen for treating malaria in adults is a one-time loading dose of 1000 mg, followed by 500 mg in six to eight hours. Then 500 mg is taken once a day for two more days.
The standard dosage for malaria treatment in children is based on the child's weight. Children are usually given a loading dose of 16.7 mg per kg of body weight (about 7.6 mg per pound of body weight), followed by 8.3 mg per kg (about 3.8 mg per pound) at 6, 24, and 36 hours after the loading dose. However, a child should never receive more than the adult dosage.
