Treatment

Lungworms are treatable with anti-parasitic (anthelminthic) medications such as:

• Fenbendazole
• Albendazole
• Ivermectin
• Praziquantel
• Levamisole

These medications should eradicate the worms over time and will help clear the animal of the infection. In severe cases, where secondary infections and lung damage have occurred, other medications such as corticosteroids or antibiotics may be necessary to help the animal recover.

Living and Management

An infection with lungworms does not typically last long. The cat often eliminates the worms by coughing them up or excreting them through the feces. Then, as long as the prescribed medication is given and the cat does not develop a secondary lung disease such as pneumonia, the prognosis is good.

In severe cases, repeat X-rays or fecal examinations may be needed to follow up.

Prevention

Cats should be kept indoors to prevent exposure to rodents, birds, or other animals which may carry the lungworm larvae.
