Yes, ivermectin is FDA-approved, but only for specific parasitic infections and one skin condition. It is not approved or authorized for the prevention or treatment of COVID-19. The confusion around this drug stems from the gap between its legitimate medical uses and the off-label demand that surged during the pandemic.
Approved Uses in Humans
The FDA has approved ivermectin in two forms for human use: oral tablets and a topical cream, each for different conditions.
The oral tablet, sold under the brand name Stromectol, is approved to treat two parasitic infections. The first is intestinal strongyloidiasis, an infection caused by a roundworm called Strongyloides stercoralis that lives in the gut. The second is onchocerciasis, sometimes called river blindness, caused by a parasitic worm transmitted through blackfly bites. Both are serious conditions common in tropical regions, and ivermectin works by paralyzing and killing the parasites.
The topical form, a 1% cream sold as Soolantra, treats something entirely unrelated to parasites: the inflammatory bumps and pimples caused by rosacea. This was approved in 2014 and is applied directly to the face. It’s a completely different use case from the oral tablets, and the two shouldn’t be thought of interchangeably.
Veterinary Uses Are Separate
Ivermectin has a long history in veterinary medicine. The injectable form (Ivomec) is approved for use in cattle, swine, reindeer, and American bison to treat and prevent various parasitic infections. The FDA has also issued an emergency use authorization for Ivomec to prevent screwworm infestations in cattle at birth, castration, or wound sites.
Animal formulations of ivermectin are concentrated for large animals and are not equivalent to human-grade medications. The doses, inactive ingredients, and concentrations differ significantly. Products designed for horses or cattle should never be used by people, a point the FDA has emphasized repeatedly.
Ivermectin and COVID-19
Ivermectin is not approved or authorized by the FDA for the prevention or treatment of COVID-19. During the pandemic, prescriptions surged based on early, small studies and social media claims. Poison control centers saw a corresponding rise in calls related to ivermectin overdoses and adverse effects, many linked to people using veterinary products.
The question of whether ivermectin might help with COVID-19 was eventually put to a rigorous test. The ACTIV-6 trial, a large randomized clinical trial funded by the National Institutes of Health, compared higher-dose ivermectin (taken for six days) against a placebo in outpatients with mild to moderate COVID-19. The results were clear: median time to recovery was 11 days in both the ivermectin and placebo groups, with a hazard ratio of 1.02, meaning essentially no difference. Hospitalizations, deaths, and emergency care visits were also nearly identical between groups (5.7% with ivermectin versus 6.0% with placebo). The researchers concluded the findings do not support using ivermectin for mild to moderate COVID-19.
Side Effects and Risks
When used at approved doses for approved conditions, ivermectin is generally safe and well tolerated. Common side effects include nausea, vomiting, diarrhea, dizziness, and itching. These are typically mild.
At higher doses or in cases of misuse, the picture changes. Neurological side effects can include confusion, lethargy, tremors, seizures, difficulty walking, and in severe cases, coma. Some people carry a genetic variation in a protein called the ABCB1 transporter that affects how the body handles certain drugs. In these individuals, even standard doses of ivermectin can cause serious neurological problems, including coma and loss of coordination.
The risk of toxicity increases substantially when people take formulations meant for livestock, which contain far higher concentrations than human tablets. Difficulty breathing, severe skin reactions, and dangerous drops in blood pressure have all been reported in overdose situations.
What “FDA-Approved” Actually Means Here
FDA approval means the agency reviewed clinical evidence showing a drug is safe and effective for a specific use at a specific dose. Ivermectin passed that bar for intestinal roundworm infections, river blindness, and rosacea. It did not pass that bar for COVID-19 or any viral infection. Doctors can legally prescribe approved drugs for off-label uses, but off-label does not mean the FDA has evaluated or endorsed that use. In ivermectin’s case, the largest clinical trials found no benefit for COVID-19, which is why no approval or authorization was ever granted for that purpose.
