How to Give Anhydrous Oral Suspension
Oral Suspension (Anhydrous) is a liquid medication that does not contain water in its base. This might be an oil-based or other special base to help stabilize the medicine. It will look like a regular liquid medication, but often needs a good shake because the drug can settle. Here's how to give it:
- Shake well each time to mix the medication (5-10 seconds).
- Measure the dose using the syringe/dropper provided or one recommended by your vet. Insert the top of the oral syringe into the bottle adapter. Turn the bottle upside down and pull the plunger until the medicine reaches the volume required
- Hold your pet steady: a towel or helper can assist with squirmy pets.
- Administer the dose slowly into the side of the mouth. Allow small pauses if needed for swallowing.
- Raise the head slightly to help the medication go down and clean any spills with a little water or tissue.
- Praise your pet and offer a treat or water (unless advised against feeding right after).
- Clean the syringe with water immediately after use. Store the bottle as directed, out of sunlight.
- Consistency is key: Shake each time, measure accurately, and contact your vet if any issues arise.

Trazodone utilizes a serotonin antagonist and reuptake inhibitor strategy to manage anxiety. It is a prescription-authorized medication frequently considered for pets presented with situational stress.
Prescription only. Use only under the direction of a licensed veterinarian. This information is not a substitute for veterinary diagnosis, prescribing or monitoring. Compounded drugs are not approved by the FDA for safety or effectiveness.
Commonly observed effects of trazodone administration include sedation, lethargy and mild gastrointestinal changes such as vomiting or decreased appetite. Some animals exhibit transient behavioral shifts, such as increased panting or a paradoxical increase in anxiety, though these are less common. Because trazodone influences serotonin levels, your veterinarian will monitor for signs of serotonin syndrome, especially if the pet is receiving other serotonergic medications. Owners should watch for signs of coordination loss (ataxia) or significant disorientation and contact their veterinarian promptly if these occur.
This medication is typically used with extra caution or avoided in patients with known severe cardiovascular disease, significant renal or hepatic impairment or a history of angle-closure glaucoma. Trazodone is also carefully evaluated for potential interactions with other prescriptions, including certain antifungal medications, antibiotics and other behavior-modifying agents. Your veterinarian is the right person to determine the appropriate monitoring schedule and provides guidance on the onset timing your veterinarian will discuss relative to specific stressful events. Contact your veterinarian promptly if you observe any unexpected physical distress or if the level of sedation appears deeper than anticipated.
Yes. Trazodone hydrochloride is a prescription medication and can only be dispensed by a licensed pharmacy upon receipt of a valid authorization from a licensed veterinarian. Mixlab verifies all authorizations before any medication is prepared or shipped to your home.
Yes. While trazodone is available as a commercial tablet, Mixlab can compound this medication into specialized strengths or alternative flavored dosage forms—such as oral liquids, chews or capsules—if your veterinarian determines a customized preparation better suits your pet's needs. The decision between a commercial and compounded product rests with the prescribing veterinarian.
Veterinarians generally discuss trazodone in the context of an onset timing that occurs within one to two hours following oral administration. For situational stressors like travel or thunderstorms, your veterinarian will provide specific guidance on the most appropriate timing for administration to ensure the medication is active during the event.
Sedation and lethargy are the most commonly observed effects of trazodone in pets. While many veterinarians utilize this effect to support rest during recovery or to manage anxiety, the degree of sleepiness varies between individual patients and is monitored as part of the management plan.
