Quick Facts

• Ivermectin: Primarily used to treat parasitic infections.
• Hydroxychloroquine: Used to treat malaria, lupus, and rheumatoid arthritis.
• Mechanism: Ivermectin targets parasites, while hydroxychloroquine affects immune response and malaria parasites.
• Forms: Both are available as oral tablets.
• Common Side Effects: Nausea, dizziness, headache for both medications.
• Key Interactions: Both interact with other medications; consult a healthcare provider.

What It Is and How It Works

Ivermectin is an antiparasitic medication commonly used to treat infections caused by roundworms, threadworms, and other parasites. It works by binding to the parasites’ nerve and muscle cells, causing paralysis and death of the parasite.

Hydroxychloroquine is an antimalarial drug also used to treat autoimmune diseases like lupus and rheumatoid arthritis. It works by interfering with the parasite’s ability to digest hemoglobin and modulating immune responses in autoimmune conditions.

Indications / Uses

Ivermectin

Ivermectin is primarily used for treating parasitic infections such as:

• Onchocerciasis (river blindness)
• Strongyloidiasis (threadworm infection)
• Scabies
• Pediculosis (lice infestations)

While ivermectin has been investigated for treating COVID-19, its effectiveness in this context remains controversial and unapproved by major health authorities.

Hydroxychloroquine

Hydroxychloroquine is used for:

• Malaria prevention and treatment
• Rheumatoid arthritis
• Systemic lupus erythematosus (SLE)

Hydroxychloroquine has been studied for COVID-19 treatment, but its efficacy is not supported by robust clinical evidence and it is not recommended by health authorities for COVID-19 management.

Dosage Forms and Typical Dosing Considerations

Ivermectin

Ivermectin is commonly available in oral tablet form. The dosing depends on the type of infection being treated, the patient’s weight, and other individual factors. It is crucial to follow the prescribing physician’s instructions and not self-dose.

Hydroxychloroquine

Hydroxychloroquine is also available in oral tablet form. Dosing varies based on the condition being treated, such as malaria prophylaxis or treatment, lupus, or rheumatoid arthritis. Patients should strictly adhere to their healthcare provider’s dosing instructions.
