I recommend you ask your vet.
I rotate with Ivermectin, Fenbendazole (which I may stop as many worms have become immune to it :( ,) and Pyrantel. I de-worm every 8 weeks.
A lot depends on how your horse is kept. Is he/she out with others? If so, you might want to do daily de-worming... Each area has different problems, also depends on where your hay comes from... Lots of stuff. I called my vet when I first got a horse, and asked for suggestions. You don't have to pay, just talk to the assistant, or whoever answers the phone, they usually know. Also if you have a vet. supply store, they can help out, as can a feed store.
You can also google equine worming or equine de-worming and come up with lots of sites. I prefer to ask the local vet though as different areas of the country have different problems.
