Hello everyone, can anyone tell me if they've had chickenpox in their children? Did you get prescribed aciclovir tablets? My older child has chickenpox, there's a rash in their throat, one doctor said aciclovir is needed, but another said it's not necessary to give. Has anyone given aciclovir to their children, did it have an effect?
