Ivermection ( NO other ingredient.) Many brands, horse wormer paste, durvet is just one of them. Each notch equals 50 pounds body weight. Round up, if you fall in between. Take 50 mg zinc daily with iver. Zinc with food. Other supplements a great idea, as desired. Vite c, 3000 units. D3, 8000 units. 1 aspirin. Did the 5 day protocol, twice. 10 days apart. Good plan, IMHO. We stay well. Then you can take one dose and zinc, twice a week during flu season or all winter. You would be very surprised how many people are doing this and just keep it on the down-low. We get ours from Valley Vet. No prescription and no requirements. Same with Tractor Supply.
