    Chloroquine and doxycycline


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Doxycycline is used primarily for chemoprophylaxis in areas where chloroquine resistance exists. It can also be used in combination with quinine to treat resistant cases of P. falciparum but has a very slow action in acute malaria, and should not be used as monotherapy. Compare Chloroquine vs Hydroxychloroquine head-to-head with other drugs for uses, ratings, cost, side effects, interactions and more. Chloroquine rated 10.0/10 vs Hydroxychloroquine rated 6.7/10 in overall patient satisfaction. Doxycycline is indicated for the prophylaxis of malaria due to Plasmodium falciparum in short-term travelers 4 months to areas with chloroquine and/or pyrimethamine­ sulfadoxine resistant.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  4. Doxycycline offers substantial but not complete suppression of the asexual blood stages of Plasmodium strains. Prescribing doxycycline in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria

    If you do want to do the switch from chloroquine to doxy, you just start taking the doxy and stop the chloroquine. Begin the doxy a couple of days before you travel south of the Panama Canal, which is where you would begin to encounter chloroquine -resistant malaria. Consists of the combination of Choloroquine and Doxycycline orally 2. The first day 900 mg of Chloroquine is given in 2 doses 600mg and then 6 hours later 300 mg. Simultaneously Capsule/Tablet Doxcycycline, 100 mg, is administered in 1 BID dose for the first day. From the second day, both are given in one single dose of 300 mg Chloroquine and 100 mg The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.

    Dosing schedules not well established in children Case reports describe dosage regimens that are effective yet tolerated, such as 12.5 mg PO twice weekly over 2 yr in a child aged 4-6 yr, and 100 mg PO twice weekly over 5 months in a child aged 12 yr; mg/kg dosing not reported Hypersensitivity to chloroquine, 4-aminoquinolones Psoriasis, porphyria, retinal or visual field changes For prevention, may use proguanil concomitantly Shown to cause severe hypoglycemia including loss of consciousness that could be life-threatening in patients treated with or without antidiabetic medications; patients should be warned about risk of hypoglycemia and associated clinical signs and symptoms; patients presenting with clinical symptoms suggestive of hypoglycemia during treatment with chloroquine should have blood glucose level checked and treatment reviewed as necessary Not effective in most areas; CDC recommends mefloquine or atovaquone/proguanil - check CDC traveler information for specific recommendations for region May cause hemolysis in glucose-6 phosphate dehydrogenase (G-6-PD) deficiency; blood monitoring may be needed as hemolytic anemia may occur, in particular in association with other drugs that cause hemolysis Monitor CBC periodically with prolonged therapy Caution with history of auditory damage Caution with hepatic disease, alcoholism, and coadministration with other hepatotoxic drugs May provoke seizures in patients with history of epilepsy Antacids and kaolin reduce chloroquine absorption; separate administration by at least 4 hr Irreversible retinal damage observed in some patients; significant risk factors for retinal damage include daily doses of chloroquine phosphate 2.3 mg/kg of actual body weight, durations of use greater than five years, subnormal glomerular filtration, use of some concomitant drug products such as tamoxifen citrate, and concurrent macular disease A baseline ophthalmological examination should be performed within the first year of initiating therapy; for individuals with significant risk factors, monitoring should include annual examinations; discontinue if ocular toxicity is suspected; patient should be closely observed given that retinal changes (and visual disturbances) may progress even after cessation of therapy In individuals of Asian descent, retinal toxicity may first be noticed outside macula; it is recommended that visual field testing be performed in visual field of central 24 degrees instead of central 10 degrees May exacerbate heart failure Not effective against chloroquine- or hydroxychloroquine-resistant strains of Plasmodium species; information regarding geographic areas where resistance to chloroquine occurs, is available at the Centers for Disease Control and Prevention (gov/malaria) Does not treat hypnozoite liver stage forms of Plasmodium and will therefore not prevent relapses of malaria due to P. ovale; additional treatment with an anti-malarial agent active against these forms, such as an 8-aminoquinoline, is required for the treatment of infections with P. ovale Cases of cardiomyopathy resulting in cardiac failure, in some cases with fatal outcome, reported during long term therapy at high doses; monitor for signs and symptoms of cardiomyopathy and discontinue chloroquine if cardiomyopathy develops; chronic toxicity should be considered when conduction disorders (bundle branch block / atrio-ventricular heart block) diagnosed; if cardiotoxicity suspected, prompt therapy discontinuation may prevent life-threatening complications QT interval prolongation, torsades de pointes, and ventricular arrhythmias reported; risk is greater if chloroquine is administered at high doses; fatal cases reported; use with caution in patients with cardiac disease, a history of ventricular arrhythmias, uncorrected hypokalemia and/or hypomagnesemia, or bradycardia ( There are no adequate and well-controlled studies evaluating the safety and efficacy of chloroquine in pregnant women; usage during pregnancy should be avoided except in prophylaxis or treatment of malaria when benefit outweighs potential risk to fetus Because of the potential for serious adverse reactions in nursing infants from chloroquine, a decision should be made whether to discontinue nursing or to discontinue drug, taking into account potential clinical benefit of drug to mother A: Generally acceptable.
