No. The FDA has not approved ivermectin to prevent or treat COVID-19 in humans. Taking large doses of ivermectin is dangerous. The U.S. poison control centers have reported serious adverse effects after people have taken ivermectin intended for use in cattle or bought online.
Ivermectin is approved for human use to treat infections caused by some parasitic worms and head lice and skin conditions like rosacea. If your health care provider writes you an ivermectin prescription, fill it through a trusted source such as a pharmacy. Take it exactly as prescribed. Never use medications used to treat animals on yourself or other people. Animal ivermectin products are very different from those approved for humans. Use of animal ivermectin to prevent or treat COVID-19 in humans is dangerous.
Signs of ivermectin poisoning include: digestive effects (nausea, vomiting, stomach pain, and diarrhea), headache, blurred vision, dizziness, fast heartrate (tachycardia), low blood pressure (hypotension), seeing things that aren’t really there (visual hallucinations), altered mental status, confusion, loss of coordination and balance, slowed breathing or heart rate (CNS depression) and seizures. Ivermectin may increase how sleepy you feel from other medicines such as benzodiazepines (sometimes called “benzos”) and barbiturates.
