Artemether and lumefantrine (Coartem) treats acute, uncomplicated P. falciparum malaria, not severe malaria or prevention, by pairing a fast-acting drug with a longer-lasting partner that clears leftover parasites; it is a usual first choice, on the U.S. market since about 2009 with no generic version listed. Most people tolerate it well, noticing mainly headache, dizziness, poor appetite or tiredness, some of which malaria itself causes. The thing to watch is its effect on heart rhythm (QT prolongation), so tell your prescriber about any heart history and every medicine you take, including St. John’s wort and hormonal birth control. Take every dose with food and finish all 6 doses.
Clinical pearls
- The second dose is due 8 hours after the first, not the next morning, so set an alarm.
- If you vomit within 1 to 2 hours, repeat the dose; vomiting the repeat means you need a different antimalarial.
- Rifampin, carbamazepine and phenytoin must not be combined with it, and skip grapefruit juice during treatment.
- Report unusual tiredness or paleness after the course ends, since delayed breakdown of red blood cells has been reported.

What Artemether and Lumefantrine Is Used For
▾
Artemether and lumefantrine is used to treat one type of malaria.
- Coartem tablets treat acute, uncomplicated malaria caused by Plasmodium falciparum in patients 2 months and older weighing at least 5 kg.
- Coartem has been shown to work in regions where chloroquine resistance has been reported.
- Coartem is not approved for severe or complicated malaria.
- Coartem is not approved to prevent malaria.
How Artemether and Lumefantrine Works
▾
Coartem combines artemether and lumefantrine in a 1:6 ratio. Together they act as an antimalarial against the parasite.
Artemether and Lumefantrine Dosage
▾
Coartem tablets are taken by mouth over 3 days, for 6 doses in total. Take the first dose, the second 8 hours later, then morning and evening for 2 more days.

2 DOSAGE AND ADMINISTRATION Coartem Tablets should be taken with food. ( 2.1 , 5.2 ) Tablets may be crushed and mixed with 1 to 2 teaspoons of water immediately prior to administration to patients, including children. ( 2.1 ) Coartem Tablets should be administered over 3 days for a total of 6 doses: an initial dose, second dose after 8 hours, and then twice-daily (morning and evening) for the following 2 days. ( 2.2 , 2.3 ) The adult dosage for patients with bodyweight of 35 kg and above is 4 tablets per dose for a total of 6 doses. ( 2.2 ) The number of tablets per dose for children is determined by bodyweight, as shown in the chart below. ( 2.3 ) Tablets per dose by bodyweight; total of 6 doses over 3 days 5 to < 15 kg 1 tablet 15 to < 25 kg 2 tablets 25 to < 35 kg 3 tablets 35 kg and over 4 tablets 2.1 Administration Instructions Coartem Tablets should be taken with food. Patients with acute malaria are frequently averse to food. Patients should be encouraged to resume normal eating as soon as food can be tolerated since this improves absorption of artemether and lumefantrine. For patients who are unable to swallow the tablets such as infants and children, Coartem Tablets may be crushed and mixed with a small amount of water (1 to 2 teaspoons) in a clean container for administration immediately prior to use. The container can be rinsed with more water and the contents swallowed by the patient. The crushed tablet preparation should be followed whenever possible by food/drink (e.g., milk, formula, pudding, broth, and porridge). In the event of vomiting within 1 to 2 hours after administration, a repeat dose should be taken. If the repeat dose is vomited, the patient should be given an alternative antimalarial for treatment. 2.2 Dosage in Adult Patients (greater than 16 years of age) A 3-day treatment schedule with a total of 6 doses is recommended for adult patients with a bodyweight of 35 kg and above: Four tablets as a single initial dose, 4 tablets again after 8 hours, and then 4 tablets twice-daily (morning and evening) for the following 2 days (total course of 24 tablets). For patients weighing less than 35 kg, [see Dosage and Administration (2.3)] .

Artemether and Lumefantrine Side Effects
▾
Most side effects are mild and settle on their own.
Common side effects
- Headache
- Dizziness
- Loss of appetite
- Weakness or tiredness (asthenia)
- Joint and muscle pain
- In children: fever, cough and vomiting
- Nausea and vomiting
When to get medical help
- Get medical help right away for signs of a serious allergic reaction, such as swelling, hives, trouble breathing or a severe skin reaction.
- Call your doctor if you have palpitations, fainting or a very irregular heartbeat, since this medicine can affect heart rhythm (QT prolongation).
- Call your doctor if you vomit your dose again after a repeat dose, because you may need a different antimalarial.
- Call your doctor if your malaria symptoms return or do not improve after treatment.
- Tell your doctor about unusual tiredness or paleness after treatment, since delayed hemolytic anemia (destruction of red blood cells) has been reported.
Artemether and Lumefantrine Warnings and Precautions
▾
- QT prolongation: Coartem can affect heart rhythm. Avoid it with known QT problems, low potassium or magnesium, or other QT-prolonging drugs.
- Food matters: If you can't eat, the infection may be more likely to return.
- Not for severe malaria: Delayed hemolytic anemia has been reported in people treated for severe malaria.
- Other antimalarials: Don't combine them unless there is no other option. Halofantrine must be separated by one month.
- P. vivax: Extra treatment is needed to clear parasites dormant in the liver.
- Recurrence: If the infection returns, a different antimalarial is needed.
Artemether and Lumefantrine Interactions
▾
Many medicines can change how Coartem works or add to heart rhythm risk.
- Rifampin, carbamazepine, phenytoin, St. John’s wort: must not be used, as they lower Coartem levels and cause loss of effect.
- QT-prolonging drugs (some antiarrhythmics, antipsychotics, antidepressants, macrolide and fluoroquinolone antibiotics, azole antifungals): added heart rhythm risk.
- CYP3A4 inhibitors, including grapefruit juice: may raise levels and QT risk.
- HIV medicines: effects vary and may reduce effectiveness or raise QT risk.
- Hormonal birth control: may be less effective, so add a non-hormonal or barrier method.
- CYP2D6 drugs (flecainide, imipramine, amitriptyline, clomipramine): should not be used together.
- Mefloquine just before Coartem: may lower lumefantrine levels, so eat well and be monitored.
- Quinine and quinidine after Coartem: use with caution, with ECG monitoring if needed.
Interactions listed in the FDA-approved label
From the Artemether and Lumefantrine prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.
- Strong CYP3A4 inducers (rifampin, carbamazepine, phenytoin, St. John's wort): Rifampin decreased exposure to artemether, DHA, and lumefantrine by 89%, 85%, and 68%, respectively, with potential loss of antimalarial efficacy. Concomitant use is contraindicated.
- CYP3A4 inhibitors (e.g., ketoconazole): Ketoconazole moderately increased exposure to artemether, DHA, and lumefantrine; increased lumefantrine could lead to QT prolongation. No dose adjustment necessary, but use cautiously with drugs that inhibit CYP3A4.
- Antiretroviral drugs (protease inhibitors, non-nucleoside reverse transcriptase inhibitors): Variable effects on artemether, DHA, and lumefantrine exposure; decreased concentrations may reduce antimalarial efficacy and increased lumefantrine may cause QT prolongation. Use cautiously.
- Mefloquine (prior use): Exposure to lumefantrine was reduced; no effect on artemether concentrations or artemether/DHA ratio. Monitor for decreased efficacy and encourage food consumption.
- Hormonal contraceptives: Coartem may potentially reduce the effectiveness of hormonal contraceptives. Use an alternative non-hormonal contraceptive method or add a barrier method during treatment.
- CYP2D6 substrates (e.g., flecainide, imipramine, amitriptyline, clomipramine): Lumefantrine inhibits CYP2D6 in vitro; may significantly increase plasma concentrations of the coadministered drug and increase risk of adverse effects, including additive QT effect. Many QT-prolonging CYP2D6 substrates should not be administered with Coartem Tablets.
- Quinine (sequential use): No effect on DHA, lumefantrine or quinine exposure; artemether exposure decreased, not thought clinically significant; additive QT effects possible. Use quinine and other QT-prolonging drugs cautiously after Coartem; ECG monitoring is advised if medically required.
- Drugs that prolong the QT interval (Class IA and III antiarrhythmics, neuroleptics, antidepressants, macrolides, fluoroquinolones, imidazole and triazole antifungals): May cause prolonged QT interval when coadministered with Coartem. Use with caution.

7 DRUG INTERACTIONS CYP3A4 Inducers: Potential for loss of antimalarial efficacy. ( 4 , 5.3 , 7.1 , 12.3 ) CYP3A4 Inhibitors: Use cautiously due to potential for QT prolongation. ( 5.3 , 7.2 , 12.3 ) Antiretrovirals: Use cautiously due to potential for QT prolongation, loss of antiviral efficacy, or loss of antimalarial efficacy of Coartem Tablets. ( 5.3 , 7.3 , 12.3 ) Mefloquine: If used immediately before treatment, monitor for decreased efficacy of Coartem Tablets and encourage food consumption. ( 2.1 , 7.4 , 12.3 ) Hormonal Contraceptives: Effectiveness may be reduced; use an additional method of birth control. ( 5.3 , 7.5 , 12.3 ) CYP2D6 Substrates: Monitor for adverse reactions and potential QT prolongation. ( 5.1 , 5.4 , 7.6 ) 7.1 Rifampin Oral administration of rifampin, a strong CYP3A4 inducer, with Coartem Tablets resulted in significant decreases in exposure to artemether, DHA (metabolite of artemether), and lumefantrine by 89%, 85%, and 68%, respectively, when compared to exposure values after Coartem Tablets alone. Concomitant use of strong inducers of CYP3A4 such as rifampin, carbamazepine, phenytoin, and St. John’s wort is contraindicated with Coartem Tablets [see Contraindications (4) and Clinical Pharmacology (12.3)] . 7.2 Ketoconazole Concurrent oral administration of ketoconazole, a potent CYP3A4 inhibitor, with a single dose of Coartem Tablets resulted in a moderate increase in exposure to artemether, DHA, and lumefantrine in a study of 15 healthy subjects. No dose adjustment of Coartem Tablets is necessary when administered with ketoconazole or other potent CYP3A4 inhibitors. However, due to the potential for increased concentrations of lumefantrine which could lead to QT prolongation, Coartem Tablets should be used cautiously with drugs that inhibit CYP3A4 [see Warnings and Precautions (5.1, 5.3) and Clinical Pharmacology (12.3)] . 7.3 Antiretroviral Drugs Both artemether and lumefantrine are metabolized by CYP3A4.

Before Taking Artemether and Lumefantrine
▾
- Do not use if allergic to artemether, lumefantrine or any ingredient.
- Tell your doctor about heart rhythm problems, slow heartbeat, severe heart disease, or a family history of long QT or sudden death.
- Tell your doctor about low potassium or magnesium.
- Pregnancy: studies haven't shown increased birth defects or miscarriage, and malaria itself is risky in pregnancy.
- Breastfeeding: no human data. Weigh benefits and risks with your doctor.
- Children: not established under 2 months or 5 kg.
- Older adults: limited study data, so consider reduced liver, kidney or heart function.
- Severe liver or kidney disease: not studied, so use caution.
Artemether and Lumefantrine Overdose
▾
There is no information on overdoses above the recommended treatment doses. If an overdose is suspected, treatment is symptom-based and supportive, including ECG and blood electrolyte monitoring.
How Your Body Processes Artemether and Lumefantrine
▾
Food greatly increases absorption: artemether rose 2- to 3-fold and lumefantrine 16-fold after a high-fat meal. Artemether peaks in about 2 hours, while lumefantrine peaks at about 6 to 8 hours.
Both are broken down mainly by the liver enzyme CYP3A4. Artemether and its active form DHA clear in about 2 hours. Lumefantrine clears slowly, with a half-life of 3 to 6 days. Neither drug was found in urine.
How to Store Artemether and Lumefantrine
▾
Store at 20ºC to 25ºC (68ºF to 77ºF); excursions permitted to 15ºC to 30ºC (59ºF to 86ºF) . Dispense in tight container (USP).

Artemether and Lumefantrine 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 Artemether and Lumefantrine — a signal of what to watch for, not proof the drug caused it.
The effects most often named in FDA reports that mention Artemether and Lumefantrine are pyrexia, vomiting, dyspnoea; about 88% of the reports were classed as serious. These are voluntary reports, so they show what people report, not how often it happens.
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 Artemether and Lumefantrine 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.
