Azathioprine is an immune-suppressing drug primarily used in veterinary medicine to treat various autoimmune diseases in dogs and occasionally ferrets. It is administered orally as a tablet and can be given with or without food. However, if vomiting occurs when dosed on an empty stomach, future doses should be administered with food or a treat.

  • Administration and Precautions:Administering Azathioprine requires precautions such as wearing gloves during handling and thoroughly washing hands afterward to prevent potential exposure. Pregnant women should avoid handling this medication due to potential risks. Additionally, it's crucial not to stop the medication suddenly; instead, it should be gradually tapered to prevent adverse effects.

  • Effectiveness and Timeframe:Azathioprine may take several doses to take effect, and its full efficacy may not be evident for several weeks. Improvement in clinical signs may not be immediately noticeable, necessitating regular monitoring and possibly laboratory tests to evaluate its effectiveness.

  • Side Effects and Considerations:Common side effects in dogs include vomiting, diarrhea, lack of appetite, and bone marrow suppression, leading to decreased red and white blood cells. Pancreatitis and liver toxicity are also potential adverse effects. Caution is advised when using Azathioprine in patients with current infections or with liver or kidney disease. It should be avoided in pets with a history of pancreatitis or breeds at high risk of developing pancreatitis.

  • Special Cases and Storage:Azathioprine is not recommended for cats due to the potential for severe adverse effects. If used in lactating animals, milk replacer should be substituted. Tablets should be stored at room temperature, between 59F to 77F, and protected from light and moisture to maintain efficacy.

Azathioprine is an important medication in managing autoimmune diseases in pets, but its administration requires careful consideration of potential side effects and precautions to ensure the safety and well-being of the animal. Regular monitoring and veterinary guidance are essential throughout the treatment process.

Azathioprine is an immunosuppressive drug normally used to treat autoimmune diseases. Specifically, it treats conditions involving the skin, blood, or multiple body systems. Azathioprine effectively treats hemolytic anemia, thrombocytopenia, arthritis, chronic liver inflammation, inflammatory bowel diseases, and myasthenia gravis.

You will notice positive responses in your pet in about three to six weeks. If your pet suffers from one of these autoimmune conditions or from Inflammatory Bowel Disease, this medication will help keep your pet healthy. Rest easy knowing that with Azathioprine, you can care for your pet in exactly the way they need.
