Chloroquine (Aralen) is an older antimalarial, on the U.S. market since about 1949 and available as a generic, that treats and prevents malaria where the parasite is not resistant and treats amebiasis outside the intestine; it seems to build up inside the parasite and block how it processes heme from blood. Short courses are usually well tolerated, and stomach upset (nausea, cramps, diarrhea), a mild headache and itching are the usual complaints. The real risks are to the eyes, heart, blood sugar and mood, so report blurred vision, a racing or irregular heartbeat, shakiness and sweating, or mood changes right away.
Clinical pearls
- For prevention, take it on the same weekday every week, starting before the trip and continuing after you leave the malaria area.
- Keep antacids and kaolin at least 4 hours apart from chloroquine, since they cut how much of it gets absorbed.
- If you use insulin or other diabetes medicines, watch closely for low blood sugar, because those doses may need lowering.
- Lock the tablets away from children, who are very sensitive to chloroquine; an accidental swallow can be fatal.

What Chloroquine is used for
▾
Chloroquine is used for several parasite infections.
- Chloroquine phosphate tablets treat uncomplicated malaria due to susceptible P. falciparum, P. malariae, P. ovale and P. vivax.
- Chloroquine phosphate tablets prevent malaria in areas where chloroquine resistance is not present.
- Chloroquine phosphate tablets treat extraintestinal amebiasis.
- It does not prevent relapses of vivax or ovale malaria and should not be used for complicated malaria such as cerebral malaria or acute kidney failure.
How Chloroquine works
▾
Chloroquine is an anti-protozoal that builds up in the acid compartments of the malaria parasite and blocks heme polymerization (the parasite’s way of handling a part of blood). It may also interfere with certain enzymes through its interaction with DNA. The exact mechanism is not fully known.
It works against the blood stages of susceptible malaria parasites, but not the liver-stage forms of P. vivax and P. ovale. Resistance is widespread, especially in P. falciparum.
Chloroquine dosage
▾
Chloroquine phosphate tablets are taken by mouth. Doses are often described as chloroquine base, and children’s doses are calculated by body weight.
- Prevention: once a week on exactly the same day, starting two weeks before exposure if possible, and continuing for eight weeks after leaving the area.
- Malaria treatment: several doses spread over about three days.
- Amebiasis: daily for at least two to three weeks, usually with another medicine that works in the intestine.
Follow your prescriber and the label for your exact schedule.

DOSAGE AND ADMINISTRATION The dosage of chloroquine phosphate is often expressed in terms of equivalent chloroquine base. Each 250 mg and 500 mg tablet of chloroquine phosphate tablet contains the equivalent of 150 mg and 300 mg chloroquine base respectively. In infants and children the dosage is preferably calculated by body weight. Prophylaxis against chloroquine-sensitive Plasmodium species Adult Dose: The dosage for prophylaxis is 500 mg (= 300 mg base) administered once per week on exactly the same day of each week. Pediatric Dose: The dosage for prophylaxis is 5 mg calculated as base, per kg of body weight, administered once per week on exactly the same day of each week. The pediatric dose should never exceed the adult dose regardless of weight. If circumstances permit, suppressive therapy should begin two weeks prior to exposure. However, failing this in adults, an initial double (loading) dose of 1 g (= 600 mg base), or in children 10 mg base/kg may be taken in two divided doses, six hours apart. The suppressive therapy should be continued for eight weeks after leaving the endemic area. Treatment of uncomplicated malaria due to chloroquine-sensitive Plasmodium species Adults: An initial dose of 1 g salt (= 600 mg base) followed by an additional 500 mg (= 300 mg base) after six to eight hours and a single dose of 500 mg (= 300 mg base) on each of two consecutive days. This represents a total dose of 2.5 g chloroquine phosphate or 1.5 g base in three days. Infants and Children: In infants and children, the recommended dose is 10 mg base/kg followed by 5 mg based/kg at 6, 24 and 36 hours (total dose 25 mg based/kg). The pediatric dose should never exceed the adult dose regardless of weight. The dosage for adults of low body weight and for infants and children should be determined as follows: First dose: 10 mg base per kg (but not exceeding a single dose of 600 mg base). Second dose: (6 hours after first dose) 5 mg base per kg (but not exceeding a single 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. P. vivax and P. ovale: Concomitant therapy with an 8-aminoquinoline compound is necessary for treatment of the hypnozoite liver stage forms of the parasites.

Chloroquine interactions
▾
Several medicines can change how chloroquine works or raise its risks.
- Antacids and kaolin: lower absorption, so separate by at least 4 hours.
- Cimetidine: raises chloroquine levels, so avoid.
- Insulin and diabetes medicines: low blood sugar risk, so doses may need lowering.
- Amiodarone, moxifloxacin and other QT-prolonging drugs: more risk of heart rhythm problems.
- Ampicillin: lowered absorption, so separate by at least 2 hours.
- Cyclosporine: levels may rise suddenly.
- Mefloquine: higher seizure risk.
- Tamoxifen: both can harm the retina, so not recommended together.
- Praziquantel and rabies vaccine: effects may be reduced.
Interactions listed in the FDA-approved label
From the Chloroquine prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.
- Antacids and kaolin: Can reduce absorption of chloroquine. Observe an interval of at least 4 hours between intake of these agents and chloroquine.
- Cimetidine: Can inhibit the metabolism of chloroquine, increasing its plasma level. Concomitant use of cimetidine should be avoided.
- Insulin and other antidiabetic drugs: Chloroquine may enhance the effects of a hypoglycemic treatment. A decrease in doses of insulin or other antidiabetic drugs may be required.
- Arrhythmogenic drugs (such as amiodarone or moxifloxacin): There may be an increased risk of inducing ventricular arrhythmias.
- Ampicillin: In healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. Observe an interval of at least two hours between intake of ampicillin and chloroquine.
- Cyclosporine: A sudden increase in serum cyclosporine level has been reported after introduction of oral chloroquine. Close monitoring of serum cyclosporine level is recommended and, if necessary, chloroquine should be discontinued.
- Mefloquine: Co-administration may increase the risk of convulsions.
- Intradermal human diploid-cell rabies vaccine: Chloroquine taken in the dose recommended for malaria prophylaxis can reduce the antibody response to primary immunization.
- Praziquantel: In a single-dose interaction study, chloroquine has been reported to reduce the bioavailability of praziquantel.
- Tamoxifen: Tamoxifen is a drug known to induce retinal toxicity. Concomitant use of chloroquine with such drugs is not recommended.

Drug Interactions Antacids and kaolin: Antacids and kaolin can reduce absorption of chloroquine; an interval of at least 4 hours between intake of these agents and chloroquine should be observed. Cimetidine: Cimetidine can inhibit the metabolism of chloroquine, increasing its plasma level. Concomitant use of cimetidine should be avoided. Insulin and other antidiabetic drugs: As chloroquine may enhance the effects of a hypoglycemic treatment, a decrease in doses of insulin or other antidiabetic drugs may be required. Arrhythmogenic drugs: There may be an increased risk of inducing ventricular arrhythmias if chloroquine is used concomitantly with other arrhythmogenic drugs, such as amiodarone or moxifloxacin. Ampicillin: In a study of healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. An interval of at least two hours between intake of ampicillin and chloroquine should be observed. Cyclosporine: After introduction of chloroquine (oral form), a sudden increase in serum cyclosporine level has been reported. Therefore, close monitoring of serum cyclosporine level is recommended and, if necessary, chloroquine should be discontinued. Mefloquine: Co-administration of chloroquine and mefloquine may increase the risk of convulsions. The blood concentrations of chloroquine and desethylchloroquine (the major metabolite of chloroquine, which also has antimalarial properties) were negatively associated with log antibody titers. Chloroquine taken in the dose recommended for malaria prophylaxis can reduce the antibody response to primary immunization with intradermal human diploid-cell rabies vaccine. Praziquantel: In a single-dose interaction study, chloroquine has been reported to reduce the bioavailability of praziquantel. Tamoxifen: Concomitant use of chloroquine with drugs known to induce retinal toxicity such as tamoxifen is not recommended (see WARNINGS ).

Before taking Chloroquine
▾
- Do not use it if you have had an allergy to 4-aminoquinoline medicines.
- Tell your doctor about retinal or visual field changes.
- Tell your doctor about heart disease, rhythm problems, slow heartbeat, or low potassium or magnesium.
- Mention psoriasis, porphyria, G6PD deficiency, kidney or liver issues, or diabetes.
- In pregnancy, your doctor should review the benefits and risks first.
- Children’s doses are weight-based and must never exceed the adult dose. Store tablets safely away from kids.
Chloroquine overdose
▾
Chloroquine overdose is a life-threatening emergency, and as little as 1 g may be fatal in children. Symptoms can start within minutes and include nausea, vomiting, headache, drowsiness, vision problems, seizures and dangerous heart rhythms. Get immediate emergency medical help.
What Chloroquine does in the body
▾
Chloroquine is active against the blood stages of susceptible malaria parasites and against amoeba forms called trophozoites. It is not active against gametocytes or the liver-stage forms of P. vivax and P. ovale. It can lengthen the QT interval, and this effect increased when it was combined with azithromycin in a study.
How your body processes Chloroquine
▾
Chloroquine is rapidly and almost completely absorbed from the gut. About 55% is bound to proteins in the blood, and it collects heavily in tissues such as the liver, spleen, kidney and lung. The body breaks it down partly into desethylchloroquine. It is cleared slowly, and this is faster when the urine is acidic.
How to store Chloroquine
▾
Dispense in tight, light-resistant container as defined in the USP. Store at 20° to 25°C (68° to 77°F); excursions permitted between 15° to 30°C (59° to 86°F)

How widely Chloroquine is used (Medicaid data)
A general measure of how commonly Chloroquine is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Chloroquine is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Chloroquine prescribed? Of the 1,601 medications we measure, Chloroquine ranks #1,394 by Medicaid prescriptions — more than 13% of them.

Chloroquine side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Chloroquine — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Chloroquine in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
