Progestins Product Profile & Position Paper

Progestins are a category of drugs, with both oral and injectable options and a variety of active ingredients, that are used for temporary suppression of reproduction in cats and dogs of both sexes. Regulatory approval and popularity varies by country.

Although in many cases effective for short-term contraception in owned cats and dogs, progestational drugs are associated with a variety of adverse effects; the risks and benefits of use in each clinical situation must be carefully evaluated under veterinary oversight.
