Quick Facts Scannable
- Paxlovid is an antiviral medication used to treat COVID-19.
- Ivermectin is primarily used to treat parasitic infections.
- Paxlovid works by inhibiting a viral protease needed for coronavirus replication.
- Ivermectin works by binding to parasites and killing them or stifling their development.
- Common side effects of Paxlovid include altered taste, diarrhea, and high blood pressure.
- Ivermectin side effects can include dizziness, nausea, and skin rashes.
- Patients should seek urgent help if they experience severe allergic reactions.
- Paxlovid is typically used in adults at high risk of progressing to severe COVID-19.
- Drugs and supplements can interact with both Paxlovid and Ivermectin.
What It Is and How It Works
Paxlovid
Paxlovid is a combination antiviral medication consisting of Nirmatrelvir and Ritonavir. Nirmatrelvir serves as an inhibitor of the SARS-CoV-2 virus\’s main protease, preventing viral replication. Ritonavir boosts the effect of Nirmatrelvir by slowing its breakdown in the liver.
Ivermectin
Ivermectin is an antiparasitic medication that works by binding to glutamate-gated chloride channels in parasites, leading to paralysis and death. While explored for off-label use in COVID-19, there is limited evidence supporting its effectiveness for this purpose.
Indications / Uses
Paxlovid
Paxlovid is primarily indicated for the treatment of mild-to-moderate COVID-19 in adults who are at high risk for developing severe illness, hospitalization, or death. It is used when the symptoms have presented for five days or less.
Ivermectin
Ivermectin is officially approved for treating conditions caused by certain parasites, including river blindness (onchocerciasis) and lymphatic filariasis. While some studies have examined its use in COVID-19, major health organizations have not recommended it for such treatment outside of clinical trials.
Dosage Forms and Typical Dosing Considerations
Paxlovid
Paxlovid is administered orally in tablet form, consisting of two Nirmatrelvir tablets and one Ritonavir tablet taken together twice daily for five days. Dosing may be adjusted for patients with reduced kidney function.
Ivermectin
Ivermectin is available in oral tablets and topical forms. Dosing for parasitic infections is typically based on the patient\’s weight and specific condition being treated. Any off-label use for viral infections should only be pursued under close medical supervision.
How to Take It Correctly Step-by-Step
Paxlovid
- Take two Nirmatrelvir tablets and one Ritonavir tablet together, with or without food.
- Avoid missing doses, and in case you do, take it as soon as possible unless it\’s near the next scheduled dose.
- Store Paxlovid at room temperature, away from moisture and heat.
- Do not share your medication with others.
Ivermectin
- Follow your healthcare provider’s dosing instructions, typically based on your weight for parasitic conditions.
- Take the tablets on an empty stomach with water unless advised otherwise.
- Store at room temperature, away from light and moisture.
- Do not use for COVID-19 unless part of a clinical trial or explicitly advised by your healthcare provider.
Side Effects Common to Serious
Common Side Effects of Paxlovid
- Altered taste
- Diarrhea
- High blood pressure
Less Common Side Effects of Ivermectin
- Dizziness
- Nausea
- Skin rash
Serious Side Effects
Both medications can cause severe allergic reactions. Seek immediate medical attention if you experience symptoms such as swelling of the face, throat, or tongue, difficulty breathing, or severe dizziness.
Contraindications & Precautions
Paxlovid
- Avoid if you have known allergies to its components.
- Not recommended for patients with severe liver or kidney problems without close monitoring and possible dose adjustment.
- Discuss risks if pregnant or breastfeeding with a healthcare provider.
Ivermectin
- Avoid if you\’re allergic to ivermectin or similar medications.
- Caution in pregnant or breastfeeding women—consult a healthcare professional.
- Use cautiously in people with liver diseases.
Drug, Food, and Supplement Interactions
Paxlovid has significant interactions because Ritonavir affects the liver enzyme CYP3A. It can lead to increased levels of certain medications, potentially causing toxicity. Inform your healthcare provider about all medications and supplements you are taking.
Ivermectin has fewer notable drug interactions, but caution is advised when used with certain medications that may also affect the liver. Alcohol and grapefruit juice can enhance adverse effects and should be avoided.
