Amitriptyline and similar are prescription drugs and I'm sure a vet in Bah'rain would be able to prescribe. However, not many pharmacies can make it up into a gel, and possibly not where you live.

I just got off the phone with the pharmacist who makes the special meds for me and she told me good news and bad news. Amitriptyline, and other anti-aggresion/anti-anxiety medications can be made up into a massage gel. However, it's active life is only 30 days from the time it is made up. They do put little cold packs into the envelope when they send them to me, but I don't know how fast mail can get to you. Also, you would need to work with a vet in the U.S. because they didn't think they could work from a prescription from a vet in Bahrain.

The drugs can take up to 2 months to show effect and there is no guarantee that they will, or that they won't cause other problems. I used both Buspar (which worked quickly but too strongly) and Amitriptyline (which worked within weeks and did work well) on my Artful Dodger, who was super aggresive and made my other cats' lives a misery. I should have cut back on the Buspar dosage, as they told me later, but seeing Dodger look like a cabbage horrified me so much that I switched to another med. It can have a dopey effect at first but the cat adjusts and then it just helps with the aggression. I tried Clomicalm with Taranis, for spraying, and it worked but made her pee only once every 36 hours which isn't good for a cat who is prone to crystals. She is on a Prozac derivative now and after a month, I've seen only a very slight change in her behavior. Since your need is urgent, and you need to really clobber her with something, it seems that Buspar or Amitriptyline would be best - but that's up to a vet.

I sincerely hope I haven't got your hopes up only to dash them. Dealing with extreme personality problems is really distressing.
