Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

Please see our full Terms of Service and Privacy Policy for more information.

  • Benadryl? Hydroxyzine? Histall?

    Milo's itching has triggered early this year.

    Last year I had to resort to steroid shots but they would only last a few DAYS. We could not keep up with those long term.

    NO 'natural remedies' touch him-no flax, ACV, spirulina...been there, nothing.

    SO I am reading about Benadryl, Hydroxyzine or Histall.

    Any experience? What is the dose for Benadryl? I read 25mg/ 100 lbs TWICE a day?

    Milo is every bit of 1500 lbs.

    Any other suggestions?

    My friends horse was put on cyproheptadine last year and did great on it. She didn't have any luck with the other antihistamines.

      My horse is getting cromolyn sodium eyedrops for his headshaking. They seem to help some, but of course you have to do eyedrops 2x a day which sucks.


      • #4
        cyproheptadine can have a side effect of increased appetite... I use it for my dog when he goes on eating strikes.
        i've always heard benadryl and horses is not a safe combo. Wish i had data to back that up

          My guy developed a case of hives this past week and the only thing I had on hand was benadryl. The vet said to give one tab (25mg) per body weight, which is about 10-15 tabs depending on your horse. She said they may be a little groggy. The hives kept continuing, and they said it would be better to try the tri-hist for long term....


          • Original Poster

            Well after speaking with my vet, we will start with Hydroxyzine first-see how it does.

            If it does not work, I will try Histall second.

            TriHist worries me as I have read that some horses develop non-sweating while on it.

            Last resort will be prednisone.

              test and desensitize?

              It sounds as though you are dealing with just one episode, but if it recurs you might get your horse tested for allergies and then go for the desensitization shots. They have really helped my two mares with allergies.

              When needed we use Hydroxizine under vet supervision also. Have used Dexamine (compounded, anti-histamine + Dex) for severe bug bite episodes.
              Forward...go forward

                i use anihist by animed for my mare's allergies and have found it to be very effective and easy to feed. it does not run the risk of causing anhidrosis like the trihist but does have a 72 hour withdrawal period before competitions! this is the only thing that keeps her from sneezing and rubbing her nose on everything in the spring! and its super cheap!

                  Had a pony break out in hives that was so bad it looked like bubble wrap under his skin. Dex is not a good option for him and he did not respond at all to Tri-Hist. Vet advised IV banamine and 8-25mg Benadryl every 12 hours until cleared. Worked like a charm and he was hive free in 24 hours. 25mg/100 lbs is the usual dose.

                    Uugghh!! I forgot about the anhidrosis factor. My guy developed that last summer. I guess I need to find another antihistamine too. I don't want to lose what little sweat he has so far this spring....


                    • #11
                      I'm glad to hear you had good luck with the desensitization injections. I started my guy on the first 180 day round last Fall. We'll be due to start the second round in a couple of months.

                      I tried everything...hydroxyzine, TriHist, Genesis topical spray, Zephyr's anti-itch spray, Depo shots. Nothing worked except the depo and which we could only give 1x per month.

                        I have an 1100lb tb that has random allergies. One adult bendryl powder capsule broken open and mixed into his food am and pm for a few days works really well for him - then i dial back to one a day to none. Dex doesn't really work for him.

                        It does make them sleepy.

                        I also feed Equinacea from Equi-lite and spirulina am and pm (although you said the spirulina didn't do much for your guy).

                          Had great results for hives and coughing with Hydroxy. Vet said its mild, and has fewer chances of side effects than other options. Did have to go to Prednisolone instead once, but figured out what the allergy was and was able to eliminate it. I asked her for the mildest options and these two were what we used.
                          Tried Benadryl, but it had no effect on the hives. Had TriHist on hand, vet said go ahead and try, but unlikely to help hives. She was right.

                          Horse was a bit sleepy shortly after given Hydroxy dose, lasted a few hours tops. I wasn't competing at the time, and just rode long after dosed.

                          Good luck

                            Did you give Hydroxy once or twice daily?

                              Have had good results with hydroxyzine and prednisolone.

                                what dosage of pred have you found successful? I know it depends-just getting an idea of dosage amounts.

                                Prednisone vs prednisolone...

                                daily vs every other day

                                  No advice just wishing you good luck. Only experience I have is that we give patients hydroxy when we sedate them so they dont get sinus drainage. Doesnt really help you though. I hope you get it figured out and find something that works.

                                    I had a horse respond well to Hydroxyzine, never had a problem with side effects. The horse was super sensitive- had to use fragrance-free detergent to wash pads, wraps, etc. and it was a battle finding a flyspay that didnt bring out the hives. Hydroxyzine kept the hives under control for the most part. If something triggered a bad outbreak IV Banamine usually did the trick.

                                      Gave Hydroxy twice per day. Same with Prednisolone. Dosages were kept to the lowest amount possible while controlling symptoms.
                                      Horse had some muscle wastage from the Pred. Pred is a Catabolic rather than Anabolic steroid, which is why it is a possible side effect. Horse was on high dose at the time, and it resolved easily as soon as we started reducing the dose. I never did find research on horses in particular on Catabolics, but did see it as a side effect for dogs and humans, and certainly seemed the case for my horse. We chose the Prednisolone because vet felt it had a much lower incident rate of founder as a side effect.

                                        Oh, and when symptoms were mild, horse was just on once per day and showed results.
