Fireworks, thunder or a change of circumstance can make Tammy very stressy but Calmex is very safe works quickly and clearly makes her settle and feel more comfortable.

45 Calm travel dog
Verified Purchase

Best product for a calm dog in transit. One capsule 30 mins before you go and no pacing or uncertainty. Makes the drive easy. Much superior to all this ethical natural nonsense!

55 Works wonders!
Verified Purchase

By on 2 December 2019

This really works after about 30 minutes. Not a drug, just vitamins and minerals but worked better on my friends's dog than prescribed nasty sedatives

The product is great. It calms Sam down and stops him being so anxious and aggressive. It’s easy to use and lasts quite well.

15 Never again.

By on 1 November 2018

I cant believe im the first to be writing a bad review on these... but Last night ive gave my chowchow these monstrosities!!!

Never again!!!....

One of the worst experiences of my life!! i honestly thought he was going to die! And i think so did he. Falling over everywhere, looked really scared, slow heart rate, uncotrollable bladder, drooling, ears down, panting heavy; completely disoriented...

This wasnt the first time hed had these pills though... the pills were/are in date, and followed the dosage to the correct guidelines. In the end we took him to the vets, and the charged us £30 to tell us to take him to the animal hospital immediately in worsley. We were seen After a 2hour wait, to be told they think its the tablets but its too late as its already in his bloodstream by this point(atleast 3hours later). That cost us £120 and the whole night of making sure he was still with us before even considering going to bed! 5am i stayed up till, just to be sure!! Was easily 12straight hours of panic and fear.

So unless you want to risk all the above;£150 just to be told they cant do anything to help you, 12hours of fear and worry your dog is going to die from all these side effects; dont give these any animal ever!!

go to your vet and ask for a prescription of diazepam(i know right!? Crazy, valium works on dogs apparently, but im not doing it!). Rather a scared dog from a few fireworks than a dead dog from you giving it tablets you dont know are going to work...

honestly never again.

Long term use with Cbd oil?


My cat is already on Cbd oil for separation anxiety but also has some absence type symptoms on waking from deep sleep which the vets feel is behavioural not neurological. They told me to give it in one dose at the opposite time of day to Cbd— is this ok? She has been on calmex (which she loves, her three brothers try and steal it!) for 30 days and so far, no ‘episodes’. Is it ok to take long term? Also does it work as one off double dose for issues such as claw cutting. Her brother has gabapentin at home for this but I’d love him to come off it, thanks

  • VioVet Staff

There is not any information readily available regarding the use of Calmex with CBD oil. It is likely this is safe but it cannot be guaranteed. We recommend following your vet's advice regarding the trreatment plan for your cats.
Yes Calmex can be used as a one off before a specific event like nail clipping. It should be given at least 1 to 2 hours before the event itself. For maximum effect you can start the product at the twice daily dosing regime a day or two before and continue this throughout the event.

Safe during pregnancy & lactation (feline)?

Dionne Collette

  • VioVet customer since 2017
  • From: Hampshire, United Kingdom

Is giving this safe to use in a pregnant or lactating cat please?

While I’m asking in relation to a cat, others may want to know for a dog too!

Thank you

Unfortunately the manufacturers (VetPlus) will not liase with us directly as per their company policy. They should be able to answer this question directly for you though, their contact details are below:

Calmex and travel anxiety

Helen Phillips

  • VioVet customer since 2013
  • From: West Sussex, United Kingdom

How soon befor travel should I give our basset calmex ? He has cronic travel anxiety. Is there anything else that we can use along with calmed? A friend suggested adaptil?

  • VioVet Staff

Hi Helen,

You need to administer the dose 30-60 minutes before the desired effect is required.

Hope this helps.

Dosage query


I have an 8.6kg shih tzu
What would his dosage be - how many tablets and how often can I give him his tablets
We have a very long car journey 6-7+ hrs

  • VioVet Staff

The dose for your dog would be half a capsule given 30-60 minutes before the start of your journey. The dose can be given twice daily. Supplements like this seem to be very effective for some dogs and not at all for others. If your dog gets particularly anxious travelling it may be worth speaking to your vet about something stronger.

How long do the effects last for

Claire Mattick-Rylands

  • VioVet customer since 2015
  • From: Devon, United Kingdom

How long does the product last once taken?

  • VioVet Staff

This will normally be for a few hours, but it varies between different animals, with some showing a more obvious effect than others. Very excited animals may not show an obvious response at all, especially when stressed.

Calmex along side adapti

Daniel McCormack

  • VioVet customer since 2015
  • From: Greater Manchester, United Kingdom

I was wondering can I use the calmex tablets along side adaptil products such as the diffusers and collar ?

  • VioVet Staff

Yes you can safely do this and sometimes combining products with very different modes of action can work well. As with all products like this, you will not really know what the results will be until you try them. It could be worth a try.

Calmex for overgrooming?

Julie Bailey

  • VioVet customer since 2011
  • From: Leicestershire, United Kingdom

My cat has a problem with stress, he often over grooms and sometimes urine marks inside my house! I currently give him Zylkene which doesn't make much difference to his behaviour, have also tried Feliway, did not work either. Would Calmex be more suitable?

  • VioVet Staff

This is a difficult problem to treat because the causes for the stress vary between cats and some individuals will respond better to one treatment than another, but not all cats will respond to the same product. Generally I find that the Feliway products are the most effective, but you might need to provide a diffuser for each room.

It is worth bearing in mind that the most stressful thing to a cat is usually another cat. It is sometimes possible to try and think of things from your cat's point of view and reduce the amount of stress they feel from neighbour's cats, or indeed your own other cats if you have any. Re-positioning things like food bowls, litter trays and sleeping areas can help sometimes.

Calmex used in welping bitch

VioVet Visitor

My bitch is feeding 7 puppies at the moment, she's gett very stressed when possible buyers come and visit could I use calmex on her??

  • VioVet Staff

It is safe to give Calmex to lactating bitches and it might well help. I would suggest using an Adaptil diffuser in the room too, which is completely safe and certainly helps some dogs a lot.

Calmex and parrots

can calmex be used for parrots

Can calmex be used for parrots with screaming problems?What will be the dosage for birds under 500gr? (African grey cockatoo)

  • VioVet Staff

This can be tried in parrots, but it may or may not make any difference. It is safe enough and you could give a dose of 0.1mls once or twice daily for an African Grey or a similarly sized cockatoo.

Calmex long term?


Can my dog be on calmex long term? and would there any side effects from taking it long term.

  • VioVet Staff

Calmex is perfectly safe and can be used long-term. We would not expect any side effects, though it is possible that the beneficial calming effect would be reduced in time.
