Sileo (dexmedetomidine oromucosal gel) is the first and only FDA-approved treatment for dogs that suffer from noise aversion. This medication is prescribed by your veterinarian to help calm your dog when your pet is frightened by loud noises. Common noise aversion triggers include fireworks, thunder, construction work, traffic or street noise, celebrations, vacuum cleaners and smoke detectors. Sileo works by blocking norepinephrine, a brain chemical similar to adrenaline that pumps up anxiety. **Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.**
