Despite the recognition that HCQ is a key component of SLE disease management in both nonpregnant and pregnant patients, adherence to HCQ remains abysmally low. The authors measured serum levels of HCQ in all 3 trimesters and related these levels to disease activity and pregnancy outcomes. Mok, et al measured HCQ levels in sera and defined 3 groups of patients based on drug level: those with drug levels < 10 ng/ml were classified as noncompliant; those with levels of 10–500 ng/ml were classified as having subtherapeutic drug levels; and a third group with levels > 500 ng/ml were classified as having therapeutic levels. The pregnancy category and safety statement for some medicines that are no longer registered for use in Australia are presented in this database for information only. It concluded that drug levels themselves cannot differentiate noncompliance from other pharmacokinetic factors10. in early pregnancy is essential to reduce these risks. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Twenty-four percent of patients had at least 1 HCQ level < 100 ng/ml, suggesting a high rate of nonadherence. This drug crosses the placenta. It should be noted that 4-aminoquinolines in therapeutic doses have been associated with central nervous system damage, including ototoxicity (auditory and vestibular toxicity, congenital deafness), retinal hemorrhages and abnormal retinal pigmentation.

Additional data assessed included the mother's age at the time of birth, mother's race/ethnicity, maternal diagnosis at the time of subsequent pregnancy, and anti-SSA/Ro-SSB/La antibody status. Hydroxychloroquine is a prescription medication used to reduce pain and swelling caused by diseases of the immune system such as rheumatoid arthritis, juvenile arthritis, and systemic lupus erythematosus (SLE). A: Generally acceptable. A team of scientists from Japan has identified the approved anti-material drug, mefloquine, as a potential candidate to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV … Women with rheumatic diseases, including inflammatory arthritis and systemic lupus erythematosus (SLE), fare better in pregnancy when their disease is under good control1,2. Centers for Disease Control "Guidelines for Treatment of Malaria in the United States. pregnant women and nursing mothers. There is evidence that HCQ may be safe during pregnancy, with previous research finding no increased risk of, prematurity, fetal death, retinopathy, low birth weight, stillbirth, or congenital defects[2-4]. Nonetheless, the rate of preterm births among those patients with optimal therapeutic levels of HCQ (> 500 ng/ml) was 80%, nearly identical to that in the nontherapeutic group (83%). Even if it is generally agreed that pregnancy per se increases disease activity in patients with SLE and that withdrawal of HCQ at the onset of pregnancy may result in exacerbation of SLE, use of HCQ during pregnancy has remained controversial for a long time. Embryonic deaths and ocular malformations in the offspring have been reported when pregnant rats received large doses of chloroquine. Hydroxychloroquine is being studied to prevent and treat coronavirus disease 2019, but all clinical trials conducted during 2020 found it is ineffective and may c According to author estimation, the infant would receive 0.11 mg/kg/day or about 2% of the mother's weight-adjusted dose. These paradoxical findings could reflect that the patients in the > 500 ng/ml group may have been sicker. Pregnancy and hydroxychloroquine. I have been involved with this problem with one patient, a 23-year-old woman who was taking 200 mg/day of hydroxychloroquine sulfate during the first 16 weeks of pregnancy as a therapy for discoid lupus erythematosus. Animal studies have revealed evidence of fetal harm; embryonic deaths and malformations of anophthalmia and microphthalmia have been observed in the offspring of pregnant rats who were administered large doses of chloroquine. No adverse effects were reported in her 9-month-old breastfed infant.After taking 200 mg (probably sulfate equivalent to 150 mg base) once or twice a day (report was unclear) before and during pregnancy, 2 women had milk levels measured after delivery; drug levels were 344 and 1424 mcg/L at unspecified times after dosing. HCQ appears more promising than chloroquine due to its greater effectiveness against SARS-CoV-2 … We studied whether HCQ was associated with lower odds of preeclampsia and preterm delivery in SLE … Comparing these approaches head to head may clarify this point. This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus. Learn about side effects, warnings, dosage, and more. Select one or more newsletters to continue. We do not capture any email address. People with psoriasis should not take hydroxychloroquine. Importantly, whatever metric is used to determine HCQ adherence, many of our patients with SLE remain undertreated, and this could affect both disease activity and pregnancy outcome. O 0. It is important to note that hydroxychloroquine does cross the placenta. This is Issue 45 in CLI’s On Point Series. In the non-SLE patient group, neither disease activity nor pregnancy outcome was related to HCQ levels; however, the numbers of subjects in each diagnostic subcategory were so small that no definitive conclusions could be drawn. METHODS: We document 9 pregnancies in 8 patients with lupus, all of whom took hydroxychloroquine (Plaquenil) throughout pregnancy. There are no controlled data in human pregnancy; however, a moderate amount of data on pregnant women (between 300 and 1000 pregnancy outcomes), including prospective studies in long-term use with large exposure, have not shown a significant increase in risk of congenital malformations or poor pregnancy outcomes.Therapeutic doses of 4-aminoquinolines have been associated with central nervous system damage, including ototoxicity (auditory and vestibular toxicity, congenital deafness), retinal hemorrhages, and abnormal retinal pigmentation.According to the US CDC, this drug is a recommended agent for the treatment of chloroquine-sensitive malaria species during pregnancy; it is also recommended as an alternative for malaria prophylaxis during pregnancy for women traveling to areas where chloroquine-resistant Plasmodium falciparum has not been reported.Malaria in pregnant women increases the risk for adverse pregnancy outcomes, including prematurity, spontaneous abortion, and stillbirth. 2002;46:1123–4). In infants up to at least 1 year of age, careful follow-up found no adverse effects on growth, vision, or hearing.This drug is usually available as the sulfate salt with hydroxychloroquine constituting about 75% of the labeled dose of hydroxychloroquine sulfate. Hydroxychloroquine, sold under the brand name Plaquenil among others, is a medication used to prevent and treat malaria in areas where malaria remains sensitive to chloroquine. Several studies demonstrate that patients with SLE who continue HCQ during pregnancy have decreased … High disease activity for patients with SLE was defined as a PGA > 1.0. The estimated infant dose averaged 0.2 mg/kg/day with maternal doses of 400 mg/day and 0.1 mg/kg/day with lower maternal doses; these corresponded to weight-adjusted infant doses of 1.9% to 3.2% of the maternal dose. Hydroxychloroquine crosses the placenta, but is considered safe to use during pregnancy. Recently, some countries face restrictions to prescribe these drugs during pregnancy, due to report of ocular toxicity in animal models and potential genotoxicity. Caution is recommended; benefit to mother should outweigh risk to the infant.-According to some experts: Use is considered acceptable.Excreted into human milk: Yes (small amounts)Comments:-Infants are extremely sensitive to the toxic effects of 4-aminoquinolines.-When used for malaria prophylaxis, the amount in breast milk is too small to cause harmful effects in the nursing infant but is insufficient to confer any benefit on the infant; the breastfed infant will require separate chemoprophylaxis.-Very limited data available regarding the safety in breastfed infants during long-term maternal therapy. Note: Doses are expressed in terms of hydroxychloroquine base: 400-mg tablet = 310-mg base; 800-mg tablet = 620-mg base Acute Malaria Adult: PO 620-mg base followed by 310-mg base at 6, 18, and 24 h Child: PO 10-mg base/kg, then 5-mg base/kg at 6, 18, and 24 h Malaria Suppression Hydroxychloroquine (HCQ) is a medication commonly used in pregnancy to treat autoimmune and connective tissue diseases such as systemic lupus erythematosus (SLE). Hydroxychloroquine is being studied to prevent and treat coronavirus disease 2019 (COVID‑19), but … As the authors point out, while whole blood testing may be more precise, serum levels may have the advantage of being less prone to confounding by cytopenias11. According to author estimation, the 2 infants would receive 0.06 and 0.2 mg/kg/day. Hydroxychloroquine does cross the placenta and is considered Category D in pregnancy (see DermNet NZ's pages on Safety of medicines taken during pregnancy and on Lactation and the skin). Hydroxychloroquine may benefit pregnancies by reducing active disease of lupus. In support of this approach, a survey of North American rheumatologists found that over 69% of rheumatologists continued HCQ in their pregnant patients6. Consult your healthcare professional (e.g., doctor or pharmacist) for more in formation. Hydroxychloroquine sulfate is a colorless crystalline solid, soluble in water to at least 20 percent; chemically the drug is 2-[[4-[(7-Chloro-4-quinolyl) amino]pentyl] ethylamino] ethanol ... Usage in Pregnancy—Usage of this drug during pregnancy should be avoided except in This drug has a half-life of over 1 month. These medications are not usually taken together. Cerner Multum, Inc. "Australian Product Information." The recent demonstration that HCQ passes across the placenta, with cord blood concentrations nearly identical to those found in maternal blood, emphasizes the need for … After the first 48 hours of therapy with a total dosage of 800 mg, a total of 3.2 mcg was excreted into her breast milk, amounting to 0.0003% of the mother's total dosage; however, it is unlikely that steady state had been reached at this time.A woman who had been breastfeeding for 9 months began taking 400 mg (as sulfate equivalent to 310 mg base) nightly; after 6 weeks of this regimen, steady-state milk levels were 1.46, 1.09, and 1.09, at 2, 9.5, and 14 hours after 1 dose, respectively, and 0.85 mg/L at 17.7 hours after a dose on the following day.

This use has shown that HCQ is very safe in pregnancy. HCQ is safe in pregnancy, well-tolerated, and costs only £0.10 per tablet in the UK. Five mothers took hydroxychloroquine 200 mg daily during pregnancy and breastfeeding, one for 30 months. Enter multiple addresses on separate lines or separate them with commas. To circumvent the possible effect of medication nonadherence on the understanding of the role of HCQ in rheumatic disease management, literature has focused on the measurement of either whole blood or serum drug levels and correlating these levels to disease activity. Flash electroretinograms performed on the infants were normal. ([2019, Oct 1]): Centers for Disease Control and Prevention "Travel-Related Infectious Diseases. In animal studies on Plaquenil (hydroxychloroquine) and pregnancy, the medication crossed the placenta and accumulated in the eyes of the fetus when it was given to pregnant animals. Abstract. FDA appears to soften stance on the use of hydroxychloroquine and says it is now 'between a patient and their doctor' just a day after Trump said he's taking the drug to prevent coronavirus (hydroxychloroquine)." Primary outcome for this study was neonatal gestational age. Hydroxychloroquine (HCQ) is widely used in the treatment of systemic lupus erythematosus (SLE). Accompanying texts should be consulted for further details. Two women who had taken hydroxychloroquine 200 mg (probably sulfate equivalent to 150 mg of base) once or twice daily (the report is unclear) before and during pregnancy had milk levels measured after delivery. Note: The Pregistry website includes expert reports on more than 2000 medications, 300 diseases, and 150 common exposures during pregnancy and lactation. Who should not take hydroxychloroquine? The role of hydroxychloroquine (HCQ) for achieving this control is now recognized. According to author estimation, a fully breastfed infant would receive 1 mg of parent drug and 0.066 mg of desethylchloroquine per day.At 7 time points between 0 and 18 hours after dosing, 13 women who were on long-term therapy donated milk samples. Although claims data have also showed that overall use of HCQ during pregnancy has improved from 12.4% in 2004 to 37.7% in 2015, these rates are far from optimal8. UT Southwestern Medical Center, Division of Rheumatic Diseases, Dallas, Texas, Sign In to Email Alerts with your Email Address. Hydroxychloroquine Breastfeeding Warnings In patients with SLE, neither the SLEDAI nor serum markers of SLE disease activity correlated with HCQ levels. Introduction. Additionally, women need to know which medications should be established pre-pregnancy (for example, hydroxychloroquine), and ensure that their blood pressure is controlled. They should take one dose per week while … How should I take hydroxychloroquine? Due to pregnancy-induced physiologic changes, some pharmacokinetic properties of hydroxychloroquine may be altered in pregnant women; however, dosage adjustments are not needed (Balevic 2019b). This observational, retrospective, single-centre cohort study aimed to assess pregnancy outcome in women with antiphospholipid antibody(aPL) treated with hydroxychloroquine (HCQ) in addition to conventional treatment during pregnancy. To view this report as a PDF, see: On Point 45 Hydroxychloroquine Use During Pregnancy In recent weeks, hydroxychloroquine (HCQ) has received significant media attention because of initial reports that suggest that it could be an effective treatment for the highly infectious respiratory disease, COVID-19, caused by the novel coronavirus, SARS-CoV-2. These authors also reported 2 other women with milk drug levels of 1131 and 1392 mcg/L at unreported times after unspecified doses (presumably 200 to 400 mg/day); according to author estimation, their 2 infants would receive no more than 0.2 mg/kg/day via breast milk.Numerous milk samples were collected from 6 women using 400 mg (n=5) or 200 mg (n=1) per day; the milk level averaged 376 mcg/L (range: 20 to 1463 mcg/L) as parent drug and 36 mcg/L (range; 11 to 111 mcg/L) as desethylchloroquine. Talk to your healthcare provider about the risks and benefits of using hydroxychloroquine during pregnancy (see Plaquenil and Pregnancy for more information). Hydroxychloroquine passes through breast milk. Use of chloroquine and hydroxychloroquine in pregnancy was not associated with adverse fetal outcomes. Hydroxychloroquine (HCQ) is a medication commonly used in pregnancy to treat autoimmune and connective tissue diseases such as systemic lupus erythematosus (SLE). HCQ has anti-inflammatory and anti-thrombotic effects and thus may improve pregnancy outcomes in couples with unexplained RPL. When administered to nursing women, hydroxychloroquine is excreted in human milk and it is known that infants are extremely sensitive to the toxic effects of 4-aminoquinolines; Pregnancy Categories. Travel to malarious areas should be avoided during pregnancy; if this is not possible, women should receive effective prophylaxis.AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. Hydroxychloroquine … A study of women with aPL who were taking hydroxychloroquine (HCQ) during pregnancy to treat lupus found that women taking HCQ had a better pregnancy outcome compared to women who do not take it, with fewer miscarriages and preterm births and a higher live birth rate. Average milk levels were dose related and ranged from 0.4 to 1.2 mg/L (mean: 0.7 mg/L) with 200 mg once a day and 0.5 to 3.7 mg/L (mean: 1.4 mg/L) with 200 mg twice a day. This low disease activity may have diluted the authors’ findings — HCQ level may have a larger effect in those patients with more active disease. But these studies have not provided overwhelming evidence proving the safety of this agent in pregnancy, Jean-Charles Piette, M.D., said at an international conference on cutaneous lupus … The relative merits of whole blood versus serum measurement of HCQ are unknown. In this trial, the investigators want to evaluate the efficacy of the combination of Favipiravir and Hydroxychloroquine as potential therapy for moderate and severe cases with COVID -19. While there is evidence of risk for damage to the eye and ear, if the benefits of these drugs in controlling RA symptoms are judged to outweigh the risks, they may continue to be used during pregnancy. Limited evidence suggests that HCQ also reduces preeclampsia and preterm birth in SLE pregnancies. The authors found significant intrasubject variability in serum HCQ during pregnancy11. The use of hydroxychloroquine in pregnancy without an increase in the rate of birth defects has been reported in the literature. Hydroxychloroquine may also reduce the chance for a baby to be born with a specific heart conduction problem, called congenital heart block. Alternatively, AZA itself could contribute to preterm and lower birth weights12. Nonetheless, the evaluation of HCQ level during pregnancy could provide valuable information for disease management. Twenty-eight patients had SLE, 7 had rheumatoid arthritis or juvenile idiopathic arthritis, 5 had connective tissue disease, and the remaining 10 had other rheumatic and autoimmune disorders. Hydroxychloroquine is usually considered a pregnancy Category C medication. B: May be acceptable. The purpose of this study was to examine lupus activity and pregnancy outcomes in women with SLE treated or not treated with HCQ during pregnancy. Although the authors found a statistically significant relationship between HCQ levels and disease activity as measured by the PGA, the r2 of 0.07 reflects a nonlinear relationship. While there is evidence of risk for damage to the eye and ear, if the benefits of these drugs in controlling RA symptoms are judged to outweigh the risks, … Anti-malarial drugs (hydroxychloroquine, chloroquine) are considered pregnancy category C drugs. Eighty-three percent of patients in this group compared to 12% in the suboptimal therapeutic group and 16.7% in the nontherapeutic groups were taking azathioprine (AZA), suggesting that these patients may have had disease that is more complex. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. hydroxychloroquine sulfate) is an arthritis medicine . Several studies demonstrate that patients with SLE who continue HCQ during pregnancy have decreased flares and improved pregnancy outcomes, including longer fetal gestation and … Hydroxychloroquine sulfate is a colorless crystalline solid, soluble in water to at least 20 percent; chemically the drug is 2-[[4-[(7-Chloro-4-quinolyl)amino]pentyl]ethylamino] ethanol sulfate (1:1). Exercise caution when administering hydroxychloroquine to nursing women; When administered to nursing women, hydroxychloroquine is excreted in human milk and it is known that infants are extremely sensitive to the toxic effects of 4-aminoquinolines; Pregnancy Categories. PLAQUENIL (hydroxychloroquine sulfate) tablets contain 200 mg hydroxychloroquine sulfate, equivalent to 155 mg base, and are for oral administration. of botulinum toxin, which can have decreased efficacy if taken with hydroxychloroquine. One possible explanation for this poor correlation is that the mean PGA among the patients with SLE was < 1.0 in all 3 HCQ therapeutic ranges, reflecting overall low disease activity in this cohort. Costedoat-Chalumeau, et al were among the first to show that HCQ concentration could predict disease activity, with whole blood drug levels of > 1000 ng/ml having a high negative predictive value of flare9. Further studies into the pharmacokinetics of HCQ in the pregnant and nonpregnant state will also be important. It appears the 8 infants reported in the letter were included among the 13 infants in the case series, but it is unclear whether the 16 infants reported in the abstract were part of the case series. The authors concluded that the benefits of breastfeeding outweighed the risk of this drug. Some studies have not been clear regarding salt form and dose of the products used and others have sampled milk after only a few doses before steady state was reached, making interpretation of some of the data difficult.In a patient starting therapy with 200 mg (salt unspecified) twice a day, the highest milk level detected was 10.6 mcg/L from 3 to 12 hours after the fourth dose.

For pregnant patients, it is recommended to continue use for those patients with SLE, as it leads to less flare-ups and has not been shown to be teratogenic in some trials. Background/Purpose: Chloroquine (CQ) and Hydroxychloroquine (HCQ) have been used for years during pregnancy for multiple indications (malaria prevention, autoimmune disorders, etc.…). In a letter, they reported 8 breastfed infants followed up at 1, 6, and 12 months of age who had normal growth and development and who had thorough, normal eye examinations at 1 and 12 months of age. Surprisingly, mean birth weight was the lowest in the group with optimal therapeutic levels of HCQ. This study was unable to establish a statistically significant relationship between serum level of HCQ and disease activity. HCQ levels were categorized as nontherapeutic (< 100 ng/ml) or therapeutic (> 100 ng/ml). Hydroxychloroquine and prednisone are considered safe during pregnancy. It is generally recommended for pregnant patients with an autoimmune disease. O 0, Cerner Multum, Inc. "UK Summary of Product Characteristics." Malaria. Hydroxychloroquine (HCQ) is known to cross the placenta and is present in similar concentrations in blood from the umbilical cord and the mother (Arthritis Rheum. Talk to your healthcare provider about the risks and benefits of using hydroxychloroquine during pregnancy (see Plaquenil and Pregnancy for more information). This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus.AU TGA pregnancy category: DUS FDA pregnancy category: Not formally assigned to a pregnancy category. The recent demonstration that HCQ passes across the placenta, with cord blood concentrations nearly identical to those found in maternal blood, emphasizes the need for careful evaluation of pregnancies in women receiving HCQ. Hydroxychloroquine does cross the placenta and is considered Category D in pregnancy (see DermNet NZ's pages on Safety of medicines taken during pregnancy and on Lactation and the skin). PLAQUENIL (hydroxychloroquine sulfate) tablets contain 200 mg hydroxychloroquine sulfate, equivalent to 155 mg base, and are for oral administration. The aim of our trial is to determine whether hydroxychloroquine given to COVID-19 positive pregnant women can reduce COVID-19-related hospital admissions, thereby allowing women to stay at home while limiting utilization of … Feldman, et al used claims data to show that 79% of nonpregnant patients with SLE are nonadherent7. The role of hydroxychloroquine (HCQ) for achieving this control is now recognized. National Library of Medicine (US) "Drugs and Lactation Database (LactMed) Available from: URL: https://www.ncbi.nlm.nih.gov/books/NBK501922/" (2006). Peak milk level was reached 2 to 4 hours after dosing. Both adults and children should take one dose of hydroxychloroquine per week starting at least 1 week . It has a half-life of over a month. Hydroxychloroquine (HCQ) is often needed to manage disease activity in systemic lupus erythematosus (SLE) during pregnancy. Hydroxychloroquine Sulfate (hydroxychloroquine)." Hydroxychloroquine is usually available as the sulfate salt with hydroxychloroquine constituting about 75% of the labeled dose of hydroxychloroquine sulfate. The latter category was further divided into suboptimal therapeutic levels, defined as drug level of 100 ng/ml–500 ng/ml, and optimal therapeutic levels, defined as drug level > 500 ng/ml. The optimal duration of therapy to achieve steady state, timing of blood draw in relation to dose administration, changes in pharmacokinetics because of pregnancy, and disease factors still represent unresolved issues.
