Anyone can/wants to share their story curing babesia and with Azithromycin and Atovaquone like described in Jack's article below.

As written mepron can be a hell of expensive drugs, while Malarone is lots cheaper
You can get enough Atovaquone and Azithromycin to cure a 40lbs dog in 10 days for not more then 200 dollar using Malarone.

Worth a try isn't it?

One of the questions i got is, has anyone tried to use Malarone instead of Mepron. Malarone contains 250 mg Atovaquone and 100mg Proguanil (chlorguanide). Mepron doesnt contain Proguanil. Wonder if it would cause problems?

PS: Not my dog, i give all my dogs berenil before contact and never had a case!
