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.

Estriol is a short-acting estrogen hormone utilized in veterinary medicine primarily for the management of hormone-responsive clinical signs in dogs. It is a prescription medication available for use in female dogs, requiring a valid veterinarian-client-patient relationship before it can be dispensed. It is frequently considered in the context of urinary health for patients presented with incontinence following spaying.

Commonly observed effects include localized digestive changes such as vomiting or a temporary decrease in appetite. Some animals may exhibit behavioral shifts including vulvar swelling or signs of attraction from male dogs. Because estrogens can influence bone marrow function, your veterinarian will monitor for observational signs of weakness or bruising, although this is less common with estriol's shorter duration of action. Owners should monitor their pet for any significant shifts in energy and contact their veterinarian promptly with concerns.
Yes. Estriol is a prescription medication and requires a valid authorization from a licensed veterinarian. Mixlab verifies all requirements before any medication is prepared or shipped.
Estriol is available in certain commercial tablet formats. If your pet requires a different concentration or flavor, Mixlab can discuss compounded alternatives based on your veterinarian's prescription.
Veterinarians discuss estriol because it replaces the estrogen necessary to manage the strength of the urethral sphincter. By managing the tone of these muscles, it provides a method for addressing involuntary urine leakage.
Your veterinarian will determine the appropriate administration schedule based on your dog’s individual response. They often adjust the frequency once the observational signs of leaking are managed.
While estriol is characterized by a short duration of action, your veterinarian will provide a specific monitoring schedule to ensure the management approach remains suitable for your pet's long-term health.
