Acetylsalicylic Acid, commonly called aspirin, is a Non-Steroidal Anti-Inflammatory drug (NSAID) which may be used for the treatment of inflammation in pets. It is typically prescribed to treat mild pain or chronic pain associated with arthritis. It may be used to treat blood clots, pulmonary disease associated with heartworm infection, or fever in pets.
How It Works
NSAIDs work by reducing the COX-1 and COX-2 enzymes. COX-2 is involved in the formation of prostaglandins which cause swelling and inflammation. Reduction of these factors reduce the pain and inflammation your pet experiences.
Aspirin® also reduces thromboxane, effecting the productivity of platelets which are needed to clot blood. This side effect may help treat blood clots in pets.
Store in a tightly sealed container. Read the storage instructions on the drug label as some forms may need to be refrigerated.
If you do miss a dose, give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
