I've noticed ivermectin horse paste sold with praziquantel.
I'm sure there's a valid reason why you feel this way. I asked because i want to take all the precautions necessary. And my reasoning usually goes along those lines. Better off take the safest route. What if it's not necessary. Especially if products already exist showing that both of these medications are already sold combined.
If i were to scale the most troubling parasitic infection it would be the strongyloides. I have no doubt that what I've been doing to treat the Tapeworm has helped diminish the strongyloides effect. However I'm mostly bothered by the skin irritation and back pulsing and spasms than the Tapeworm kick in my gut. If i can take care of both issues why wouldn't I?
