Kitten with worms. Re treat in a week or 2 weeks

[Kaffiene]

Hi
Just noticed worms in our 4 month old kittens poo. Have got enough Drontal to treat him, our adult cat and dog but when should I give a second dose? Is it a week or 2 weeks after?
Thanks

Monthly till they are 6 months old, then every three months. You need to allow worm life cycle to happen.

Thanks, googling was sending me round in circles.
Tablets in.
Reminder set.
