Unless you weigh 300 pounds, 24 mg/day is way too much.

According to the interwebs, half life is only 18 hours.

I had the same issue the last time I took it. I have inner ear issues and dizziness anyways though. Nothing a little Dramamine couldn't fix until the ivermectin got out of my system. I figured it wasn't a bad side effect if it was getting rid of the cold.

IVM acts as a bomb in your digestive tract. It kills parasites. Is your cold/flu symptoms due to parasites? Or is it something else? Like a fungus/mold issue.

I would never take IVM as a preventive medicine, period. I've used it before, but guardedly. To me, it is more of a nuclear bomb used only when absolutely necessary. Sometimes its better to let your own body rid itself of whatever toxin is producing those symptoms. Aerobic exercise and sweating are good for expelling toxins. Try using a sauna a few times to see if that makes you feel better. For now, you should lay off the IVM. You might want to use a brine solution or other to flush your sinuses. There are different types of sinus flush/pump devices that are effective in mitigating and ending those symptoms.

Are you taking them on an empty stomach?

I took it at night since it made me a bit dizzy. 24mg is a 240 pound dose so it if makes you dizzy cut it in half to 12 if you are taking 12mg tablets. Are you taking the Zinc, Vit D and C with it?

My wife is diabetic, so she had to reduce her insulin since it reduces Insulin resistance. It's a good idea to take it with some sweets or fatty foods/carbs. I had to reduce my blood pressure meds.

We still take 12mg once or twice a week and don't get dizzy from that but still take it before bed.

Stop taking it. Start researching what in it causes dizzyness and why it does. Very important to know why it makes you dizzy. Your Dr will just say "stop, thats why your dizzy" and pretty much ignore any other possibilities.

Lil dab will do ya, syringe from feed store is marked w/ weight , im 200# that equates to amount about size #2 pencil eraser .

Been to Mexico twice and 4 RV parks that were 100% so guess it works and im definitely NOT wormy any more!

You may have taken too much. I’m not a doctor but I wouldn’t worry too much. You’re probably experiencing parasite die off symptoms. When the parasites die, they release toxins and your body is trying to process the toxins. Most people get terrible headaches as the main issue. It’s important to help your liver and kidneys process them. Drink lots and lots of lemon water and try to eat really healthy next few days. The cleanse I did was 18 day one, skip a day, 1/2 dose, skip a day, 1/2 dose. It gives your body time to process.

Unless you are real big boy that's way too much IVW. Just huff some oregano oil in simmering water. You do not need the IVM. As soon as you feel cold/flu symptoms get a small pot with shallow water in it. Once you start to see the steam add a couple drops of 100% oregano oil to the water. Breathe it in slowly through your nose and mouth and as deeply into your lungs and sinuses you can. If you cough it's ok because it's a bit harsh.

Someone else i know had that problem too but he was also taking blood pressure meds. If you have a blood pressure cuff check blood pressure sitting and then immediately upon standing.

It should not drop 20 points or more, if it does you might try eating a canned soup, salty broth or something like that. See if that helps to bring your BP back up on standing. Recheck bp in about 30 minutes after eating something salty.

Try sitting with legs elevated also.

Take some Gravol, ginger ale and drink lots of fluids.

You OD’d yourself but IVM is safe enough that you’ll be okay.
