    I keep hearing people talking about different wormers that you should not be giving to your horses. I have heard of terrible side effects including death. I am looking for a list of safe wormers to give my horses. I don't want to give the wrong thing. I am sorry if this is posted somewhere else but I have not been able to find out which ones are causing the side effects and which ones are safe. Thanks everyone.

    There is a stickied thread at the top of the health section. It should be able to answer your question. Basically you want to treat for tapes twice a year, spring and fall. I use Quest Plus in spring and Equimax in fall. Then, get fecs done every once in awhile to see if you need to worm with anything else, otherwise your good to go.

    The 2 I listed are the safest, because those are the ones that should be used.

    Any of the wormers can be "dangerous" if you don't know how much to dose and how often.

    It won't let me edit my post, so to add I think Zermetricin Gold has been shown to sometimes give a horse mouth ulcers.

    I know I saw one on facebook that said that their horse got very sick and eventually died from a certain type of wormer. I can't remember which one. These were experienced horse people that have been worming their own horses for a long time and just switched wormers. Just was wondering if anyone knew of any that have been known to be unsafe. I know i have seen somewhere else that Equest can be dangerous too because of one of the ingredients in it. Also is there one that is safest for use on a pregnant or nursing mare.

    All of the equine dewormers on the market are safe when used according to the label. (You MUST read the labels.) The risk of adverse reactions with these dewormers is extremely low. However, there are always chances for adverse reactions. Even for Zimectrin Gold and Quest, both of which have received negative press but which has been blown out of proportion by the circulation properties of internet information (a single incidence gets spread and spread and respread and facts often get left out and all of this makes the situation look worse than it is), are safe when used according to the label and have a less than 1% incidence of adverse reaction. (The numbers for the Zim Gold causing oral ulcers is something like 1 in 10,000 doses. And I wonder if the ulcers actually form due to the presence of bot fly larva in the oral mucosa which die and then cause a reaction in the tissues.)

    So, you can use any product labelled for horses on the market so long as you use it according to the label. The real focus should be how to design a deworming program that is going to be effective with the least uses of dewormers.

    Ok thanks everyone for the advice. I have never had any problems worming my horses before but with everything going around on the internet about the horses getting sick over wormers had me a little worried. If it is all just a rare occurrence that makes me feel better. Is there any you would suggest for the pregnant or nursing mare though, or are they all safe for them.

    Several years ago, Bimectin had an issue with how the dewormer was mixed and it overdosed (and I heard actually killed) some horses.

    It seems like there is someone that has had issues with pretty much each dewormer. I keep hearing people say "never use Quest" yet I find that it works very well for me (and it one of the few wormers that worms have not developed a resistance to yet).

    Regarding pregnant or nursing mares: Read the instructions/labels on the dewormer. Personally, I'd ask my vet as she is better informed regarding which wormers work best in our area and which (if any) may cause problems.

    All of the equine dewormers currently on the market are approved for pregnant mares. However, you should always read the label. And be sure to read the deworming thread at the top of this forum to help you time your dewormings appropriately.
