Common Drugs & Nutraceuticals
Information about the common veterinary prescription and over-the-counter drugs, medications, supplements, and nutraceuticals used in dogs and cats is important for pet owners. The names, forms, storage, dose, administration, uses, side effects, contraindications, toxicities and warnings for these compounds are described in this section. These drugs and supplements are listed alphabetically and by category based on the compound's use. If you cannot find the drug or supplement you are looking for, use our handy search function.

Remember that all of these compounds should be used with care and under the supervision of your veterinarian. Doses vary considerably with the size, health condition, age, and even the breed of the animal. Some drugs have an 'extra-label use,' which means they may be given at a dosage or for a condition for which they were not FDA-approved. Using more than one drug or supplement at the same time can greatly affect their effectiveness and toxicity. Always check with your veterinarian before giving any drug or supplement, and be sure your veterinarian knows about all of the drugs or supplements your pet may be taking.
