Medroxyprogesterone acetate (MPA) is a synthetic progesterone. It is commonly used in humans as a form of birth control, and it may also be used in pets to suppress heat cycles. It can also be used to treat behavior problems such as aggression, spraying or marking.
How It Works
Progesterone is a sex hormone found naturally in pets. At high doses, synthetic progesterone can prevent the ovaries from producing eggs. At smaller doses, it may slightly alter your pet’s behavior. It reduces sex drive in males, making them less likely to be aggressive towards other males. Also, if you have a male pet that roams in search of a mate, MPA can prevent this behavior.
Store in a tightly sealed container at room temperature.
If you 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.
