Terbutaline is a beta₂-adrenergic agonist (bronchodilator). What that means: it activates certain receptors in the smooth muscle of the airways, causing those muscles to relax. When the airway muscles relax, the passage widens, air can flow more freely, and breathing becomes easier. It’s given via tablets (sometimes compounded to liquids or other forms) under veterinary direction.

Terbutaline should only be given under the direct supervision of a veterinarian. It should never be administered to animals with a known hypersensitivity or allergy to the drug. Use this medication with caution in pets with diabetes, high blood pressure, hyperthyroidism, or those receiving thyroid supplements (such as L-thyroxine). Extra care is also advised in animals with a history of seizures or epilepsy. Terbutaline should generally be avoided in pets with heart rhythm abnormalities or significant cardiac disease, as it may worsen these conditions.This medication can interact with other drugs, so it’s important to share a full list of medications and supplements your pet is receiving with your veterinarian. Potential interactions may occur with certain antidepressants, anesthetics, beta-blockers, and other medications that affect the heart or nervous system. Only your veterinarian can determine if terbutaline is safe and appropriate for your pet’s specific health needs.
