Is there any treatment of an overdose of Ivermectin in a guinea pig?

I have no idea. Would a hydration subcue help at all? Just tossing out ideas.

off topic, maybe. But how long does it take for the pig to start showing symptoms of overdose?

red blur - is a pig showing signs of illness? Do you think you miscalculated or mismeasured?

red blur... are they pigs in your care? If so, they are "your" pigs. Are they showing signs of illness?

Did some googling. Mostly dog info. Basically hydration subcue treatments, activated charcoal and handfeeding are the way to go. Oxygen if neccesary.

Activated Charcoal!!!!

Signs of overdose, including stumbling, tremors, blindness, disorientation or
weakness, generally occur within 12 hours of overdose.
In heartworm positive dogs,
supportive treatment for shock may be required.

The most common causes of ivermectin toxicity is
administration of excessive doses (10-20X the
recommended dose).

Treatment

Treatment is largely supportive and symptomatic, as
there are no specific reversal agents
available to treat ivermectin toxicity. Care may
include:

Intravenous fluid and supplemental electrolyte
therapy

Nutritional support via intravenous feeding or
through a feeding tube

Appropriate bedding, frequent turning, physical
therapy and lubricants for the eyes for
the recumbent patients

Mechanical ventilation (respirator) for the
patients who have respiratory depression

For what it´s worth, horses usually start showing signs something is wrong a few hours after treatment. With pigs, I´d expect it to be even sooner, since their metabolism works faster.

Are you really sure it´s Ivermectin OD? Was this diagnosed by the vet who didn´t want to treat them in the first place and suggested Tang for vitamin C? Could this be a case of a vet who really doesn´t know what´s wrong, but is pissed you did the Ivermectin yourself?

That would have to be a HUGE error.

My vet administered Ivermectin to my gp´s. First dose all was well. Second dose - ten days later - the gp immediately started small siezures(sp?) that lasted about two minutes. Then about an hour later almost passed out. Slept heavily for four more hours and then returned to normal. I saw the vet weigh and measure out correct dose. We suspect he hit the spine with needle. He says the gp was allergic.

I think you´re right (or on the right track). Another good reason for oral or topical dosing.
