Unless your vet gave you specific instructions, the dewormers are different medications and do not interact, so they can be given at the same time. The only reason to separate the dewormers would be if there is a large worm infestation and the deworming is likely to cause diarrhea. To be on the safe side, you could wait 2 days after the roundworm medication to give the tapeworm medication. I have included links below to the most common roundworm and tapeworm dewormers. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1862 http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=531 Good luck! I hope that was helpful. Thanks for using PetCoach.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If the first medication was only for round worms and wasn't broad spectrum (gets tapeworm too) then you can give a 2nd dewormer that JUST gets tape worms. I hope this helps and I wish Babycakes the best!

If I gave my cat roundworm medication within the past 24 hours then found out it was tapeworms, can I immediately give her medication that is meant to treat both tapeworm/roundworm? Or will that be too much roundworm medication within 24 hours? Thank
This would depend on the ingredients that you gave today and the ingredients in the tapeworm medication. There are a number of roundworm medications and I would not repeat a similar drug within 24hours but if the drug is a different drug class I would be less concerned. Your vets office may have a tapeworm only preparation available also. Please repost with more information on the active ingredients in the products if you would like further help

Can I give my cats tapeworm dewormer(praziquantel) and roundworm liquid(piperazine) the same day?
Thank you for contacting Boop by Petco with your question. Since these medications kill two different kinds of worms, that's fine to give to Mia. I'd give her one of them today and then the other tomorrow. I hope this helps!

We thought our cats had tapeworms and roundworms, but under closer inspection we saw that the worms looked like only tapeworms. We gave them medicine for roundworm (containing 250 mg of piperazine per 5 ml) and 3 out of 4 of them have puked. Are my c
Thank you for contacting Boop by Petco with your question. It’s fine to give them the tapeworm medicine but I would wait until tomorrow. Then give it to them with some food like white meat chicken (no bones). I hope this helps!

Hi, I have 2 cats and they've been having some bowel issues - pretty sure its tape worm so I gave them each a worming tablet. One of them threw up afterwards but I'm not sure how soon after, or whether they threw up the tablet or not. I'm also not su
Hello and welcome to Boop by Petco. As long as the worming tablet was in for about 30min then you don't need to give a second tablet. However a 2nd tablet, as long as it is one designed for cats, won't cause a problem. They have very high safety margins. Best of luck with your kittens!

Hello! I'm a groomer, and a client relinquished her flea and tapeworm infested cat to our shop. My question is are these two drugs compatible when given within 24hours of each other? Cat seems healthy otherwise, and is decent weight. Capstar for cats
Hi and thank you for your post on Boop by Petco! Yes, Capstar and Praziquantel used together or within 24 hours of eachother as you asked is just fine. However, just make sure the cat is at least 4 weeks old for use of Capstar and at least 6 weeks old for use of Praziquantel. I hope this helps and thank you for posting! Best of luck to you!

Ho I wanted to know if I can give my cat a second dose of tapeworm meds after 24 hours of the forest dose doesn't work or if she doesn't take all of it
This will depend on the type of tape worm medication. You should use only a proper tape worm medication containing praziquantel or one prescribed by your veterinarian. If your cat regurgitates the praziquantel wormer you can give her another dose the next day. If she only took part of it, give her the rest of the dose preferably 1/2 hour later.

We care for outdoor cats and know that they have tapeworms (evidence on their fur near hindquarters). Catching them and taking them to be tested/treated is unlikely as they’re mostly feral. We managed to get (most of) a bayer tapeworm tablet into eac
Hello, and thank you for using Boop by Petco. In this case, if follow-up fecal testing isn't possible/practical, I recommend repeating the treatment 2 weeks later. However, I would encourage you to call your primary vet and talk about your options. If your outdoor cats have tapeworms, they very likely have roundworms and/or hookworms as well, so ideally the cats should be treated with something a bit more broad-spectrum. You're right that vets certainly prefer doing an exam on each animal prior to dispensing medication (we are legally required to have a "doctor/patient relationship" to dispense medication).....but depending on your relationship with your vet, some vets may make exceptions when it comes to deworming outdoor/feral cats. It's worth asking what they recommend in this case! Hope this helps - it's great that you're caring for these outdoor cats!

Can i give safeguard dewormer and comfortis flea med. At the same time
Hello, & thank you for using Boop by Petco. Technically, yes you can, but I recommend separating the 2 medications by a couple of hours, or even give one on one day & the other the next. This is just in case Rebel gets an upset tummy & vomits, you do not lose everything. Hope this helps. Take care.

My five month old kitten has these little white not even inch-long around her fur and butt area within the last day or so she supposedly was dewormed but I think it needs done again I ordered the Bayer free tablet deworming tapeworm medicine from Pet
Puppies and kittens need a series of repeated deworming medications. And even if they have been dewormed, it is common for them to have other intestinal parasites since there are so many different types of parasites and they each require a specific type of deworming. What you are describing is likely tapeworms, so hopefully the tapeworm medication will work. I am including more information about tapeworms below. https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951442 Since tapeworms are transmitted by fleas, you will also need to make sure that Ariel doesn't have fleas or she may have tapeworms again. I would also make sure that your veterinarian has checked a fecal sample on her to see if there are any other microscopic intestinal parasites that need to be treated, but may require a different type of dewormer. Good luck! I hope that was helpful. Thanks for using Boop by Petco.
