Question 1

What is Hydroxychloroquine?

Accepted Answer

Hydroxychloroquine is a medication classified as both an antimalarial and a disease-modifying antirheumatic drug. It is used to manage certain types of parasitic and inflammatory conditions by affecting the body's immune response and biological processes.

The medication works by interfering with the growth of specific organisms or by altering the way the immune system functions. These actions help to decrease inflammation and limit tissue damage associated with chronic health issues.

Question 2

What is Hydroxychloroquine used for?

Accepted Answer

Hydroxychloroquine is used to treat:

Malaria

Rheumatoid arthritis

Systemic lupus erythematosus

Question 3

How does Hydroxychloroquine work?

Accepted Answer

Treating Malaria

Hydroxychloroquine belongs to a class of medications known as antimalarials. When used for malaria, it works by killing the parasites that cause the infection. It can be used to prevent malaria in people traveling to areas where the disease is common, or to treat an active infection.

Treating Autoimmune Conditions

For conditions like rheumatoid arthritis and systemic lupus erythematosus, hydroxychloroquine is classified as a disease-modifying antirheumatic drug (DMARD). While its exact mechanism for these conditions is not fully understood, it is believed to work by:

Modulating the immune system: It may interfere with the communication between cells in the immune system.

Reducing inflammation: By affecting the immune response, it helps decrease the inflammation, pain, and swelling associated with these diseases.

Preventing flares: In lupus, it helps reduce the frequency of symptom flare-ups and may prevent long-term organ damage.

Because it targets the underlying disease process rather than just the symptoms, it may take several weeks or months of consistent use before the full benefits are noticed.

and others.

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Hydroxychloroquine?

Accepted Answer

Hydroxychloroquine belongs to the antimalarial and immunomodulator drug class.

Question 8

What is the dosage of Hydroxychloroquine and how do I take it?

Accepted Answer

How to Take

Hydroxychloroquine is taken by mouth. It is important to take this medication exactly as directed by a healthcare provider. To help prevent stomach upset, it should be taken with a meal or a glass of milk. Tablets should be swallowed whole; do not crush or chew them.

Frequency of Use

The schedule for taking this medication depends on the condition being treated:

Lupus or Rheumatoid Arthritis: This medication is typically taken once or twice every day.

Malaria Prevention: For preventing malaria, the medication is usually taken once a week on the same day each week. It is often started before traveling to an area where malaria is common and continued for several weeks after leaving.

Malaria Treatment: When used to treat an active malaria infection, it is usually taken in a specific sequence of doses over several days.

Missed Dose

If a dose is missed, it should be taken as soon as it is remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped. Do not take two doses at the same time to make up for a missed one.

Question 9

Is Hydroxychloroquine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

The decision to use hydroxychloroquine during pregnancy often depends on the condition being treated. For individuals with autoimmune diseases like lupus or rheumatoid arthritis, healthcare providers may recommend continuing the medication because a disease flare can pose significant risks to both the parent and the pregnancy. When used for malaria prevention, the risks of contracting malaria are generally considered more dangerous to the fetus than the medication itself.

While some research suggests that hydroxychloroquine does not significantly increase the risk of major birth defects, the available data is limited. It is essential to discuss the potential risks and benefits with a doctor if you are pregnant or planning to become pregnant.

Breastfeeding

Hydroxychloroquine passes into breast milk in small amounts. Because the medication stays in the body for a long time, it can accumulate in a nursing infant. While many clinical guidelines consider the use of hydroxychloroquine to be compatible with breastfeeding, the long-term effects on the infant are not fully known. Parents should consult with their healthcare provider to evaluate the safety of breastfeeding while taking this medication.

Question 10

What forms and strengths does Hydroxychloroquine come in?

Accepted Answer

Hydroxychloroquine is primarily available in the following form:

Oral Tablet: This medication is manufactured as a tablet intended for oral administration.

While the medication is standardly produced as a solid tablet, healthcare providers or pharmacists may sometimes provide instructions for alternative administration methods for patients who have difficulty swallowing tablets.

Question 11

What is the FDA approval status of Hydroxychloroquine?

Accepted Answer

FDA-Approved Indications

The U.S. Food and Drug Administration (FDA) has approved hydroxychloroquine for the following medical uses:

Treatment and prevention of malaria in areas where chloroquine resistance is not present.

Treatment of systemic lupus erythematosus and discoid lupus erythematosus.

Treatment of acute and chronic rheumatoid arthritis in adults.

COVID-19 Regulatory History

In early 2020, the FDA issued an Emergency Use Authorization (EUA) for hydroxychloroquine to treat COVID-19. However, the FDA revoked this authorization in June 2020 after clinical trial data indicated the drug was unlikely to be effective for this use and that its potential benefits did not outweigh the known risks.

The FDA currently cautions against using hydroxychloroquine for COVID-19 outside of a hospital setting or a formal clinical trial. This caution is based on reports of serious heart rhythm problems and other safety concerns.

Safety Communications

The FDA has issued safety communications regarding the risk of serious heart-related adverse events associated with hydroxychloroquine. These risks include:

QT interval prolongation, which can lead to life-threatening heart rhythms.

Ventricular tachycardia and ventricular fibrillation.

Increased risk of heart rhythm issues when used in combination with other medications, such as azithromycin.

The FDA Adverse Event Reporting System (FAERS) has also identified potential signals of serious risks, including neuropsychiatric events and severe skin reactions, which the agency continues to monitor.

Question 12

What should I know about Hydroxychloroquine and covid?

Accepted Answer

Effectiveness and Safety

While hydroxychloroquine was initially studied as a potential treatment for COVID-19, large-scale clinical trials have demonstrated that the drug does not provide a clinical benefit for treating or preventing the virus. Consequently, the U.S. Food and Drug Administration (FDA) revoked the Emergency Use Authorization (EUA) that previously allowed its use for certain hospitalized patients with COVID-19.

FDA Warnings

The FDA has issued warnings against using hydroxychloroquine for COVID-19 outside of a hospital setting or a formal clinical trial. Using the medication for this purpose can lead to severe health risks, including:

Serious heart rhythm problems, such as QT interval prolongation.

Ventricular tachycardia or fibrillation.

Increased risk of heart-related death, particularly when used in combination with the antibiotic azithromycin.

Other potential risks include severe liver and kidney issues, as well as blood glucose disturbances. Because the known and potential risks outweigh the lack of proven benefits, health authorities advise against its use for COVID-19.
