Bivirkningerne af Heartgard Plus ormebehandling

Den gamle ordsprog om, at forebyggelse er bedre end en kur, er aldrig mere sand eller vigtigere end med dit kæledyr og ormbehandlinger. Roundworm, hookworm og heartworm overføres let via myg eller fæces og påvirker derfor ofte vores kæledyr. Hvis ormene ikke behandles, kan orme sprede sig og vokse, hvilket skaber alvorlige komplikationer for dit kæledyrs tarm- og luftvejssystemer. En ormangreb kan føre til alvorlige fordøjelsesproblemer, hjertesvigt og endda død for dit kæledyr. 

Britiske folk i det 16. århundrede elskede stege. Problemet var, at kød stegt på en spytte skulle vendes konstant, og uden teknologien måtte dette gøres for hånd. Dette var opgaven for den laveste køkkendreng, indtil turnspit kom med. 

Det er meget sandsynligt, at enhver hvalp eller hund er blevet udsat for orme. Hvalpe skal orkes hver anden uge indtil 12 ugers alder, og ammende hunner skal også behandles. Hunde over 12 uger gamle kræver hyppig behandling resten af deres liv. 

Heartgard Plus fås i forskellige doseringer til dyr med forskellig vægt. Det kommer som en tyggelig og lækker velsmagende tablet (eller sådan har jeg observeret). Doseringen er designet til at tygges i stedet for at sluges hel, så du altid kan bryde den op og tilføje den til dit kæledyrs mad, hvis det er nødvendigt. Du skal sørge for, at dit kæledyr spiser hele dosis, så observer dem under administration og i kort tid bagefter.

Det er meget vigtigt, at du taler med din dyrlæge, inden du påbegynder en behandling af hjerteorm. Ikke kun for at verificere den korrekte dosering, men der kan være alvorlige reaktioner, der ligner giftigt chok, hos dyr, der allerede har hjerteorminfektioner og derefter får hjerteormmedicin. Din hund skal testes, og hvis inficeret, voksne hjerteorme og larver (microfilariae) behandles, inden du begynder et kursus med ormkontrol.

Velkommen Nir

rundorm
Rundeorme (ascarider) er de mest almindelige orme, der påvirker hunde og katte. 
Næsten hver hvalp er inficeret med rundorm ved fødslen eller bliver inficeret via deres modermælk. 

Voksne orme findes i tarmen og kan vokse 2-3 mm brede og op til 20 cm lange. Rundeorm forårsager diarré og opkast, vægttab, dårlig vækst, en pot-bellied udseende og sløvhed. Hvis ubehandlet eller i alvorlige tilfælde, kan lungebetændelse og hindring af tarmen eller fordøjelsessystemet opstå.

Hos inficerede dyr lægger de voksne orme æg, som derefter udvises i fæces. Andre dyr bliver inficeret ved at indtage forurenet jord eller spise andre inficerede dyr, såsom mus, gnavere eller fugle. Æggene klækkes derefter ud i dyrets mave, fodrer med indhold, der findes her og udvikler sig til æglæggende voksne. Rundeormlarver og voksne kan også findes i andre organer, såsom leveren og lungerne, men forbliver generelt i fordøjelsessystemet. 

hageorm
Krogeorm er en anden tarmparasit, der oftest rammer små hunde og katte. Ormene hænger fast på værtsdyrets tarmsfor og lever af blod, væv og væske. Som med rundorm lever larver og voksne æglæggende orme i tarmen. Nogle larver binder sig til andre organer og kan være særligt problematiske for dit kæledyr, hvis de vandrer gennem åndedrætssystemet. 

Krogormeæg udvises i dyrets fæces. Hunde og katte kan inficeres ved indtagelse af forurenet jord eller fra larver, der trænger ind i huden. Hvalpe kan også inficeres gennem deres modermælk.

 

Blodig diarré er et almindeligt symptom på hookworm. Andre tegn på infektion er tarmforstyrrelser, svagt tandkød, vægttab, forkrøbt vækst og dårlig pelsforhold. Alvorligt blodtab og anæmi kan skyldes, at et stort antal orme er til stede eller hos hvalpe. I ekstreme tilfælde kan dette føre til død.

Hjerteorm
Hjerteorm er den dødeligste af alle parasitter, og selvom infektion er mere almindelig hos hunde, er katte også modtagelige. Ormene beboer dyrets lunger, hjerte og lungearterier og kan forårsage hjertesvigt eller død. 
Hvalpe skal begynde at forebygge hjerteorm ved mindst 12 ugers alder. 

Primært er det faktisk lungerne, der er påvirket af hjerteorm, men hjertet, kredsløbssystemet og endda lever og nyrer kan også blive beskadiget. Symptomerne, der indikerer hjerteorminfektion inkluderer hoste, åndenød, åndedrætslyde, besvimelse, sløvhed, vægttab, blod til stede i spyt eller slim, abdominal hævelse, opkast og appetitløshed.

Hjerteorm overføres af myg, og når en inficeret myg bider et andet dyr, overføres varmewormlarverne (microfilariae). Disse larver vandrer gennem væv og værtsdyrets kredsløb til lungerne, hjerte- og lungearterierne, lever af blod og vokser til modenhed, nogle orme kan nå 30 cm i længden og 2 cm i bredden. Hjerrevormlarver kan overleve i blodbanen hos et værtsdyr i to år. 

Hjerteorm vil føre til betændelse i væv, blodkoagulation og fortykning af blodkarvæggene. Dyrets blodtryk stiger, og hjertestammen øges. 

Der er meget alvorlige bivirkninger, hvis en hund behandles med forebyggende medicin og allerede er inficeret med hjerteorm.

Bivirkninger
Som med enhver medicin er der potentialet for ubehagelige bivirkninger og muligheden for individuel følsomhed for nogle kæledyr. Test viser imidlertid, at Heartgard Plus er sikkert og tolereres godt, når det bruges korrekt, med en meget lav forekomst af fordøjelses- og neurologiske bivirkninger. 

Heartgard Plus bruger ivermectin, der forårsager lammelse og død af de parasitiske orme. Dosen af ivermectin indeholdt i Heartgard er relativt lav og har lille risiko for bivirkninger. Som nævnt er det vigtigt, at du ikke starter et ormeprogram, før dit kæledyr kontrolleres for tilstedeværelsen af hjerteorm. 

Kontroller den nødvendige dosis til dit kæledyr, da alvorlige bivirkninger ofte skyldes, at der administreres en større dosis end anbefalet. Hvis den givne dosis er korrekt, og du bemærker nogen af de bivirkninger, der er anført nedenfor, skal du straks tage dit kæledyr til dyrlægen.

  • Problemer med fordøjelsen . Den mest almindelige bivirkning forbundet med Heartgard Plus er fordøjelsesproblemer såsom kvalme, opkast og diarré. I kliniske feltforsøg blev opkast eller diarré inden for 24 timer efter dosering kun observeret i 1,1% af tilfældene.
  • hypersalivation
  • Depression og sløvhed. Depression, sløvhed, manglende appetit og tab af interesse for aktiviteter er blevet bemærket i nogle kæledyr.
  • Mangel på koordination (ataksi), desorientering og lammelse af bagben
  • Stumling, løb ind i vægge og møbler eller lammelse kan forekomme.
  • Udvidede elever (Mydriasis) eller blindhed
  • Græder, agitation
  • Lav kropstemperatur og hypotermi
  • Krampeanfald og muskeltremor . Anfald, rysten og kramper er meget sjældne og kan betyde, at dit kæledyr har en særlig følsomhed, doseringen er for høj, eller at hjerteorm allerede var til stede.

Modtagelige racer
Nogle hundeacer har en mutation i multi-medikamentresistensgenet (MDR1), hvilket gør dem mere følsomme over for ivermectin ved meget forhøjede dosisniveauer (16 gange mere end det anbefalede niveau). I forsøg blev der ikke observeret bivirkninger hos hunde ti gange den anbefalede dosis af Heartgard .

Denne genmutation er kendt for at forekomme hyppigst hos racer såsom Collies, australske hyrder, Shelties og langhårede whippets. Niveauet af ivermectin, der bruges til forebyggelse af hjerteorm, er generelt sikkert og på et lavt niveau, der er egnet til disse hunde. Du kan tale med din dyrlæge om at teste din hund for genetisk mutation.

Når doserings- og behandlingsinstruktioner følges, er Heartgard Plus en sikker og effektiv ormeplejeplan. Det er godkendt til dyr så små som 6 uger og drægtige eller ammende katte og hunde. Administration af medicinen er så simpelt som at give dit kæledyr en tyggelig behandling hver måned. Emballagen har også en kalender, så du aldrig mister oversigten over, hvor du er op til. Fred i sindet har aldrig været så let.

Hi,
I am not an expert but I am a breeder. I have lost a breeding dog with HeartGard before, and my other dogs have had serious side effects, vomiting every day, and constantly being tired and depressed. It took about a week for them to heal. I did some research and it is because they're pesticides that some dogs can't handle. Most dogs can handle it with only minor side effects, but others have very serious side effects, and, in some cases, death. I have even had some clients who told me they lost their dog to this medecine. (HeartGard) The best solution is to avoid HeartGard and other pesticide medicines. Always go for the organic and natural ones!
Hope your dog(s) feels better soon!

My dog Molly was treated for heartworms in July last year & was heartworm free at her 6 month check up. As suggested, I've continued to give her heartguard monthly. However, for the past 2 minths, I've noticed her coughing the day after it's given & the cough lasts a day or two. Suggestions?

Did your dogs leg issues get better? I gave all 4 of mine Heartguard Sunday and Tuesday one of my dogs started having back leg pain. She still seems like it’s bothering her.

I gave my Lab/Basset her Heartguard dose Sunday and since the following Tuesday her back left leg has hurt her. I’ve been researching hip dysphasia symptoms and joint pain in senior dogs but thought I’d check to see if MAYBE any other dogs had leg pain after their heart worm meds and found this thread. Did your dogs leg issues clear up?

I have a 2 year old shepherd we adopted. They agency said she was Heartworm free. We did a Heartworm test after we had her and we had been giving heart heart guard( I have a lab too which has been on Heartgard no issue) she was diagnosed last year with micro flare and we started the slow kill treatment with heart guard plus. Last year she had a spell we’re she just payed down and like she passed out. We rushed her to dr and they gave her a Benadryl and she was fine in about and hour. This was during the slow kill treatment. We had her tested last year after the slow kill and test showed Heartworm free. She had another spell 3 weeks ago and it was worse. I picked her up and carried her to Dr and she just payed there with trashy clinches. He ran blood work ( liver enzymes a little escalated) and exrays and everything was normal. He felt she had a seizure. He told us to bring her back (today) and he tested her again and liver was fine. He did test for Heartworm again and now she is back micro flare positive, not sure how we should proceed?
HELP!!!!!

My mixed breed adopted pup, 16 months old, had an issue back in the early winter with her hind legs to the point she ended up on steroids. During the rest of the winter I was a slacker when it came to giving the Heartgard Plus and her leg pain had resolved. I restarted the med on Saturday and Saturday evening she was limping so badly I had to help her into the bed. (She acted like her knee was painful). By Sunday morning she was barely limping, but even today the limp is still noticeable. I'm starting to wonder if there is a correlation.

I gave my 8 week old puppy 1st dose of heartguard and had seizures the same day. I saw that convulsions can be a side effect. Brought her to the vet and liver enzymes were ok but still having seizure 1-2 x a day. Gave the medicine Dec 15. Vet said it’s just a coincidence because the med is safe for puppies. I’m worried. Help!

I’ve given my dog Heartgard for over 4 years without issue but this month she has an episode where she lost control over her limbs and she was scared! She couldn’t walk and was trembling! A couple hours later she was totally fine. I can’t help but wonder if it was the Heartgard?

My miniature schnauzer started having trembling in his back legs about a year ago. In June, 2020 he had an episode of stumbling and loosing control of his hind legs. I've had him to the vet and we've gone through a ton of tests including a consult with a neurologist and nothing. His last episode was in Nov. I have always taken him off Heartgard and Frontline during the cold months. It's been 14 weeks since he had an episode of problems in his back legs. I started researching the effects of Heartgard and Frontline and have become concerned that these drugs are the cause of his problems. He's 12 1/2 yrs. old. I'm not going to put him back on either of those drugs.

3 outta my 4 dogs that have been giving heartgard had episodes of vomiting and diarrhea 2 to 3 days after each dosage. Living in Louisiana it is hard not to give preventative even though my dogs are inside dogs. But it has been 5 days since I gave another dose and now my french bulldog is having leg tremors and is very lethargic. I usually have healthy, happy dogs unless it is the mosquito time of the year. Everyone might as well spray the yard with pesticides instead of giving it as a treat, What is the difference? Heart worms will kill a dog but we need a better preventative solution. I DONT WANT MY DOG TO SUFFER from a medication or a parasite. I know this is why my dogs are acting this way because there is no other explanation. I gave my 2 boys imodium for 2 days and the diarrhea finally stopped, but had to use the adult pill the children's imodium did nothing. As for my girl, she is resting because I gave her a pain pill. Only thing I can do is wait for this stuff get out of their system and don't give it again. Off to the vet in the morning. Good luck everyone.

Our coonhound is allergic to one of the ingredients in heartguard and had terrible diarrhea after each dose. We've switched to interceptor and no more issues. Doesn't taste as good, but a little peanut butter does the trick.
