Diphenhydramine HCl is an antihistamine commonly used in dogs and cats to alleviate allergy-related itching and mild allergic reactions. It is typically given orally and can also cause mild sedation, which is sometimes helpful for travel anxiety or motion sickness in pets, making it a versatile medication for allergy symptom relief in veterinary medicine.

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.
