Sileo® Gel is a veterinary dexmedetomidine oral formulation used to help dogs during noise events. It is given into the cheek pouch so it absorbs through the mouth lining. This page explains what it is, how to use it safely, and how to access it with US delivery from Canada, including options if you pay without insurance.
What Sileo Is and How It Works
This medicine contains dexmedetomidine, an alpha-2 adrenergic agonist. It reduces the physiologic arousal linked to sudden loud sounds such as fireworks or thunderstorms. When placed between the dog’s cheek and gums, it is absorbed through the oral mucosa and may lessen fear responses. It is not a tranquilizer in the traditional sense; rather, it calms by decreasing norepinephrine signaling in the central nervous system.

Veterinarians prescribe this treatment for the management of noise aversion. It is used as needed at the onset of noise, with the potential for repeat dosing during ongoing events under the labeled schedule.
Who It’s For
This treatment is intended for canine patients with established sensitivity to loud or unexpected sounds. Dogs that pace, tremble, hide, or vocalize during storms or fireworks may be candidates. It helps reduce acute signs without changing behavior outside of noise events.
The phrase sileo for dogs refers to this labeled use in canines. Dogs with severe heart disease, significant liver impairment, or those in shock or very debilitated states should not receive this class without specific veterinary guidance. It is not approved for use in people or other species.
To learn more about the condition itself, see our overview of Canine Noise Aversion.
Dosage and Usage
Follow your veterinarian’s instructions and the manufacturer’s label. The syringe is designed with a dosing ring and gradations corresponding to body weight bands. Give the first dose when your dog shows the earliest signs of fear related to noise, or shortly before a predictable event when instructed by your veterinarian.
Administer by placing the tip between the cheek and gum and pressing the plunger to release the measured amount. Do not let your dog swallow the gel directly; absorption is intended through the mouth lining. If needed during a prolonged event, a repeat dose may be given after a waiting interval, typically no sooner than two hours. Do not exceed the allowed number of doses per event as stated on the label.
The term sileo gel dosage appears on many dosing charts online; however, always confirm the exact weight-based setting on the syringe with your veterinarian. After dosing, avoid giving food immediately so the gel can remain in contact with the cheek pouch. Replace the cap securely and store the device as directed.
Strengths and Forms
This product is supplied as a prefilled oromucosal gel in a multi-dose syringe for canine use. A commonly referenced concentration is 0.1 mg/mL dexmedetomidine. The device includes a plunger, cap, and a locking ring to set the measured amount.
Pack sizes and regional presentations may vary by manufacturer lot and market. Some owners search for sileo 3ml, which refers to a syringe fill volume available in many markets. Your veterinarian will advise the correct presentation for your dog’s weight and treatment plan.
Missed Dose and Timing
If you intended to give a dose at the onset of a noise event and missed it, give it when you first notice fear-related signs, as long as the dog is calm enough to handle safely. Do not stack doses too closely. Keep the labeled minimum interval between doses, and do not exceed the maximum number per noise event. If signs persist or worsen despite use, contact your veterinarian for guidance.
Storage and Travel Basics
Store at room temperature in a dry place away from direct sunlight. Keep the cap tightly replaced after use, and ensure the dosing ring remains at the correct setting before the next administration. As with any veterinary medicine, keep out of reach of children and other animals.
If you travel with your dog during storm seasons or holidays, carry the syringe in its carton. Bring a copy of your prescription and your veterinarian’s instructions if you cross state lines. Avoid extreme temperatures in cars or luggage. If the gel appears discolored or the device is damaged, consult your pharmacist or veterinarian before use.
Benefits
As an oromucosal gel for dogs, this treatment offers on-demand use at the first signs of noise stress. Owners can administer it at home without needles. The dosing ring and weight-based markings support consistent delivery. Many dogs remain responsive to surroundings while calmer, which may help with comfort measures your veterinarian recommends.
Side Effects and Safety
Common effects can include mild to moderate sedation, drowsiness, or lethargy. Some dogs may show pale gums, slow heart rate, unsteady gait, or vomiting. Excess salivation may occur if the gel is swallowed rather than held in the cheek pouch. Most effects are transient and relate to dose and sensitivity.
As a dexmedetomidine oromucosal gel, the treatment can lower heart rate and blood pressure. Serious but less common risks may include profound sedation, significant bradycardia, or hypotension, particularly if other sedatives are used. Dogs with cardiac disease, severe hepatic impairment, respiratory compromise, or those who are very young, geriatric, pregnant, or nursing require individualized veterinary assessment. If your dog collapses, has trouble breathing, or shows persistent vomiting, seek urgent veterinary care.
- Common effects: sleepiness, lethargy, pale gums
- Gastrointestinal: vomiting, transient drooling
- Neurologic: unsteady gait, reduced responsiveness
- Cardiovascular: slow heart rate, low blood pressure
Report unexpected or severe reactions to your veterinarian. Keep a record of the dose time, amount, and your dog’s behavior to assist clinical decision-making.
Drug Interactions and Cautions
Use caution with other central nervous system depressants, including trazodone, benzodiazepines, opioids, or certain antihistamines. Combining sedating agents can deepen effects. Beta-blockers, calcium channel blockers, or antiarrhythmic drugs may have additive impacts on heart rate and blood pressure. Discuss all medicines, supplements, and preventives your dog receives.
Do not use in dogs with known hypersensitivity to dexmedetomidine. Use veterinary supervision in dogs with cardiac conduction abnormalities, severe systemic disease, or those at risk for dehydration or shock. Avoid food immediately after dosing to maintain cheek contact time.
What to Expect Over Time
Onset can be gradual as the gel absorbs through the oral tissues. Your dog may appear calmer and less reactive to loud sounds while remaining arousable. Effects can vary by individual sensitivity, noise intensity, and timing of dose. Keep your dog in a quiet, safe space during noise events, and combine use with your veterinarian’s behavior and environmental strategies.
Track response over several events. Note triggers, timing, and dose settings to refine your plan with your veterinarian. Consistent preparation around predictable events, like holidays, may help improve overall control of signs.
Compare With Alternatives
Veterinarians may consider other options depending on your dog’s medical history and response. For situational sedation, some clinicians use oral acepromazine; see Atravet when appropriate. In clinic or procedural settings, injectable dexmedetomidine may be selected; see Dexvetidine Vial as an example of that class. Each option differs in onset, depth of effect, and monitoring needs.
Selection should be individualized. Do not substitute or combine medicines without veterinary approval.
Pricing and Access

Availability and Substitutions
Supply can vary by market and season. If the product is temporarily unavailable, your veterinarian may recommend an alternative or interim plan. For example, another dexmedetomidine presentation may be considered in clinical settings; see Dexmedesed Vial for reference. Any substitution requires a clinician’s direction.
Patient Suitability and Cost-Saving Tips
This treatment may suit dogs that experience predictable or repeated noise triggers and are otherwise healthy. Dogs with significant cardiovascular, hepatic, or respiratory disease require careful evaluation. It is not intended for daily long-term anxiety management outside of noise events unless directed by a veterinarian.
To reduce overall costs, ask your veterinarian about multi-event planning and whether a larger supply aligns with your dog’s weight and the labeled dose limits. Consider setting refill reminders before holidays or storm seasons. Some owners choose to buy sileo for dogs ahead of travel plans or expected celebrations so they are prepared.

What is Sileo Gel used for in dogs?
It is a dexmedetomidine oral gel indicated for the treatment of noise aversion in dogs, such as fear during thunderstorms, fireworks, or other loud events.
How do I give the dose correctly?
Set the dosing ring for your dog’s weight, insert the tip between the cheek and gum, and depress the plunger so the gel coats the cheek pouch. Avoid immediate feeding to support absorption.
How often can I repeat a dose?
Follow the label. A repeat dose may be given after a waiting interval, typically no sooner than two hours, with a maximum number of doses per event. Your veterinarian will confirm the schedule.
What if my dog swallows the gel?
Some absorption may still occur, but efficacy could be reduced and drooling or vomiting may occur. Do not redose immediately. Contact your veterinarian if you are concerned.
Can I use it with other calming medicines?
Use caution with other sedating drugs. Combining central nervous system depressants can deepen effects on alertness, heart rate, and blood pressure. Ask your veterinarian before combining therapies.
How quickly does it start working?
Onset can be gradual as it absorbs through the mouth lining. Give at the first signs of noise-related fear, or as directed by your veterinarian before a predictable event.
Is it safe for senior dogs?
Older dogs can be more sensitive. Dogs with heart, liver, or systemic disease need careful evaluation before use. Your veterinarian will determine suitability and dosing based on health status.
