Since you didn't post a photo of what product you have then it is hard for me to say much. It does sound like tapeworms based on your description and if you got a tapeworm specific dewormer then it is the correct product. Bayer is a good, reputable company. All the dosing information should be on the bottle as should the side effects to look for. Dosing is based on weight so be sure you have as accurate a weight as you can get. Usually there are no side effects. You need to basically shove the pill down his throat and then follow that with a little bit of water to be sure he has actually swallowed the pill(s). You should repeat the dosing in 3-4 weeks. If you don't know how to give your cat a pill I suggest you watch some YouTube videos on how to do this. There is an "art" to it. If you would like to post again with a couple photos of the bottle we can maybe give you more specific information. We would also need the cat's weight. Be advised that cats get tapeworms by ingesting fleas that contain the tapeworms larva so you also need to treat him for fleas.
