Megestrol Acetate Oral Suspension (Anhydrous)
Megestrol acetate is a synthetic progestin hormone used in animals, primarily dogs and cats, to manage reproductive issues and certain behavioral or skin conditions. It is only available by prescription from a veterinarian.
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.

At a pharmacological level, it is considered to influence the body's hormonal environment by mimicking the effects of progesterone. Commonly observed effects include behavioral shifts such as increased appetite (polyphagia), weight gain and temporary lethargy. Because it influences metabolic pathways, your veterinarian will monitor for observational signs of blood sugar changes or mammary tissue shifts. It is typically evaluated carefully in patients with known diabetes mellitus or hepatic challenges. Owners should monitor for any significant shifts in activity or thirst and contact their veterinarian promptly.
