Started giving these tablets a week before November terror time. And to a large extent they worked well. My dogs were still affected but not as badly as previously. I will certainly be using them again at New Year.

Below are some recent questions we've received regarding VetIQ Serene-UM for Dogs & Cats, including answers from our team.

How long can I use Serene


Can I use serene calming tablets everyday to help my dog with separation anxiety

  • VioVet Staff

Yes these tablets can be used daily for as long as is required. If you are still struggling then you can also try spray/diffuser calmers alongside these tablets, please get in touch with our customer services if you would like any further recommendations.

Serene v Yucalm


I currently use Yucalm for my highly strung cocker spaniel after being recommended by my vet. She has been on Yucalm for nearly a year. It has helped to a point but I feel she needs something more in the run up to fireworks night as she getting extremely anxious. Would serene be taken with Yucalm or instead of?

  • VioVet Staff

Serene-UM contains some similar ingrdients to YuCalm so you may not see a significant difference adding this in too. I recommend adding in a spray/diffuser calmer such as Pet Remedy or Adaptil instead. These will work differently to oral calmers and so can provide an added extra effect.
I recommend reading our blog 'Dealing with firework phobias' for full advice on how to approach the season.

Serene um drops and Metacam


Can I use your serene um drops and metacam for my cat?

Cat has the metacam for pain relief, which will be on for a few more month. Vets will review. But cat is very nervous to loud
noises so would like to try your drops at the same time

  • VioVet Staff

Yes both these products can be used together safely.

Serenum and selgian


  • VioVet customer since 2016
  • From: North Yorkshire, United Kingdom

Can serenum be given at the same time as selgian. My cockapoo is 18months old with hip dysplasia. He's had 2 ops and had chronic pain. He gets very stressed at times usually later in the day or when strangers or lots of people are about when at home and can then be aggressive. At other times and when out and about he is very friendly. Serenum helped a bit but now the vet has started him on selgian

  • VioVet Staff

These products can safely be given together and it is fine to do that. I would suggest that you get some advice from an experienced dog behaviourist or trainer as aggression like this will not usually get better with medication alone. A very good understanding of the causes of aggression/why he gets "stressed" will be needed if it is to get better. Some cocker spaniels (red ones) I have known in the past became fiercely protective of their beds, the car, or other things and then were very aggressive if an attempt was made to force them to move. If they were encouraged to walk away from the focus of this happily, then the aggression would evaporate completely. I have no idea exactly what is happening with your dog of course, but it is certainly worth getting good advice from someone who can assess your situation knowledgeably.

Calming Tablets

Rhona Cox

  • VioVet customer since 2013
  • From: Dumfries and Galloway, United Kingdom

My very anxious 10 yr old GSDX is progressing towards end stage CDRM. I have used Zylkene in the past but it stopped being effective after a few months. She is on Calmex at the moment, which works slightly, but it is not strong enough. Could you tell me if any or all of the following can be used together: Calmex, Seren-um, Adaptil Collar and Stay Calm? I would like her to be relatively stress free, without sedation, for the short time she has left.
Kind regards

  • VioVet Staff

There is a slight duplication of ingredients between Calmex and Serene-um, though they still could be used together. Both Adaptil and Stay Calm are based on different ingredients and could theoretically be mixed with any or all of the other products. Personally I would certainly try Adaptil plus at least one of the others.

Agresive to other days / pulling on lead


I have a long hair Jack Russel black n white, I think he's about 9 now as I took him over about 2 years ago, I feel he was allowed to do what he wanted /ate what they had, He's a lovely dog although seems to want to be right by your side, How ever He couldn't go past a motor bike or lorries /vans / buses, He's not to bad now although could be better, However His one big problem is he cant go past dogs with out * Having a go* some he is ok with Now he knows the dog ''so to speak'' Other dogs he will try and lung to them he barks /growls at them, I find that I don't really want to take him out walking, In a park / on the sea front he will try and get to other dogs making a nusence of himself, I get so cross '' although I try not to show it, ''' I don't want to give him up as he could be such a lovely dog if he didn't pull/growl/bark and just walk past other dogs leaving them alone, Regards Gerry Sandford

  • VioVet Staff

Small terriers are often nervous of big dogs and tend to show this with a show of aggression. This becomes their well-practiced strategy for dealing with the situation and becomes entrenched. The Serene-Um might well help reduce the tendency, but a lot of training would also be needed and you would get some good advice if you go to www.apbc.org.uk

Can i give my rottie serene um extra with medication from vets for arthritis and can i give them longterm.thankyou so much.

  • VioVet Staff

Serene-um is not associated with any interactions or unwanted side-effects when used with any arthritis medication. You should be able to use them long-term together. (All of the prescribed arthritis medications are quite potent medicines however and they are slightly prone to problems in themselves. You should talk to your vet about these and always take care to give the correct dose. Stop medication if any vomiting or diarrhoea are seen.)

Serene-um xtra


I have an elderly greyhound who is nervous of a lot of things ie rain . She has been on Diazepam for a couple of years but recently I decided to try your tablets . I give her2 tablets a day and she seems really calm . She usually has 3 5mg Diazepam on a daily basis
Could I continue with your tablets long term basically for life if she has no problems and what side effects should I look out for . Pauline

  • VioVet Staff

Serene-Um is intended for long-term use and can be given life-long. If you intend to stop the diazepam (which is probably a good idea) then you should do so very gradually. Her body will have become used to the medication and so you should cut the tablets in pieces and monitor things as you very slowly withdraw them over a number of weeks I would suggest. (I know the tablets are small but I would still suggest splitting them if you can.)

Long term use

VioVet Visitor


  • VioVet Staff

It is completely fine to use these tablets daily and long term.
