Below are some recent questions we've received regarding Calmex, including answers from our team.
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
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 does the product last once taken?
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.
I was wondering can I use the calmex tablets along side adaptil products such as the diffusers and collar ?
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.
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?
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.
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??
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.
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)
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.
Can my dog be on calmex long term? and would there any side effects from taking it long term.
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.
Hi. I have a border terrier that suffers from intermittent panic attacks and is quite nervous generally. She responds well to calmex during an attack but just wondered if there is another product safe to use daily at a lower dose to keep her more settled day to day.my vet advised to give her half a calmex capsule but the other half is generally wasted as you have to break open the capsule and enevitably it spills out on the floor....making it more expensive.
Alternatively, as we know it works, could I give her the calmex syrup instead and what dose would be a good daily maintenance dose?
Can this be used alongside a Feliway diffuser?
Yes, Calmex and Feliway can be used together to help your cat to feel reassured and calm. They work in different ways- Calmex ingredients support the nervous system and help with serotonin function-a chemical messenger that to promotes the feeling of well-being. Feliway is a synthetic copy of a cat pheromone which they use to mark objects and territory (including their owners) as familiar. The pheromone given off by Feliway will make them feel more at ease with their surroundings, during stressful events and other situations like introducing a new pet.
My dog suffers from separation anxiety, is fearful of noises, new situations, chases traffic, barks incessantly.
I have already tried rescue remedy, stressless and silent4 - all to no avail.
He is currently on Zylkene once daily and this has helped a little bit but he is still very nervy.
Can he take Calmex in conjunction with the Zylkene?
Can the calmex be taken for long periods?
Does the Calmex have any effect on fertility?
You can use Clamex for long periods and along with Zylkene and other treatments. However I would say that it sounds like your dog is particularly difficult in this way and most non-prescription treatments will not be powerful enough to have much effect. Often the best combination is Zylkene and Adaptil. Otherwise a low dose of Xanax can work well, but this is prescription-only and you would need it to be prescribed by your vet. Ask your vet about it. Sometimes it works dramatically well for dogs, but some show no response. None of the products would be expected to affect fertility.
