Anyone had Drontal make their dogs tummies upset?

Emma had a horrible night the night before last....she didn't sleep the entire night in her crate. She cried, howled, was gawd awful. Now I do understand she is 9 weeks and I did expect this the first few nights home but she has been an angel in her crate. The only thing we can think is we gave her the drontal tablets in the afternoon (as prescribed by the vet as he found a small amount of worms in her stool sample).

I tried looking it up online and there wasn't too much info?

Just wondering if anyone else ever had their labbys react to it? She was back to her normal self last night Thankfully We felt like we had been hit by a MACK Truck! LOL!
