Chloroquine is indicated for your suppressive treatment as well as acute attacks of malaria due to P. vivax, P.malariae, P. ovale, and susceptible strains of P. falciparum. The drug is also indicated for that treating extraintestinal amebiasis.
Take chloroquine with meals or milk to minimize stomach upset, unless otherwise directed from your doctor.
t is essential which you take chloroquine only as directed. Do not take really it, don't take it more frequently, and don't take on it much more time than your physician ordered. To do so may increase the probability of serious negative effects.
If you take chloroquine to maintain from getting malaria, keep taking it to the full time of treatment. If you have malaria, you need to still keep taking chloroquine for that full time of treatment even if you set out to feel good after a couple of days. This will help to pay off up your infection completely. If you stop taking chloroquine too soon, your symptoms may return.
Chloroquine is most effective once you go over a regular schedule. For example, if you are to go on it weekly in order to avoid malaria, it's always best to go on the same day each week. Or if you're to take two doses each day, one dose could be taken with breakfast as well as the other using the evening meal. Make sure that you just do not miss any doses. If you've got any questions concerning this, talk with your wellbeing care professional.
If you miss a dose of chloroquine, get it as soon as possible. However, when it is almost time for your forthcoming dose, skip the missed dose and get back to your regular dosing schedule. Do not double doses.
The dosage of chloroquine phosphate is often expressed regarding equivalent chloroquine base. Each 500 mg tablet of ARALEN provides the same in principle as 300 mg chloroquine base. In infants and children the dosage is preferably calculated by bodyweight.
Malaria: Suppression - Adult Dose: 500 mg (= 300 mg base) on the exact same day of per week.
Pediatric Dose: The weekly suppressive dosage is 5 mg calculated as base, per kg of bodyweight, but should not exceed the adult dose no matter weight.
If circumstances permit, suppressive therapy should start a fortnight prior to exposure. However, failing this in older adults, a basic double (loading) dose of merely one g (= 600 mg base), or perhaps in children 10 mg base/kg could be used two divided doses, six hours apart. The suppressive therapy ought to be continued for two months after leaving the endemic area.
For Treatment of Acute Attack.
Adults: An initial dose of a single g (= 600 mg base) followed by one more 500 mg (= 300 mg base) after six to eight hours as well as a single dose of 500 mg (= 300 mg base) on every one of two consecutive days. This represents an overall dose of 2.5 g chloroquine phosphate or 1.5 g base in three days.
The dosage for adults of low weight as well as infants and children should be determined as follows:
First dose: 10 mg base per kg (although not exceeding a single dose of 600 mg base).
Second dose: (6 hours after first dose) 5 mg base per kg (although not exceeding just one dose of 300 mg base).
Third dose: (24 hours after first dose) 5 mg base per kg.
Fourth dose: (36 hours after first dose) 5 mg base per kg.
For radical cure of vivax and malariae malaria concomitant therapy with the 8-aminoquinoline compound is necessary.
Extraintestinal Amebiasis: Adults,1 g (600 mg base) daily for two days, accompanied by 500 mg (300 mg base) daily for about two to three weeks. Treatment is usually combined having an effective intestinal amebicide.
Store the medicine in a very closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of kids.
