BEAPHAR Worming Syrup for Puppies & Kittens  is a generic wormer effective against ascarid roundworms.

Piperazine was already used as a human medicine at the end of the 19th century. Its anthelmintic properties for animals were discovered in the 1950's. It is still used on livestock and pets, although it has been vastly replaced with more effective compounds, especially in ruminants (cattle, sheep and goats). It is also used in anthelmintics for humans, but also in antidepressants, antihistamines, antipsychotics, etc. Piperazine derivatives are also used in plastics, resins, and other industrial materials, as well as an adulterant in the psychedelic drug scene.

Piperazine derivatives have a narrow spectrum of anthelmintic activity. They are especially effective against adult ascarid roundworms (in pets e.g.Toxocara canis and Toxocara cati). Worm stages in the tissues (e.g. migrating larvae) are less susceptible than those inside the gastrointestinal tract.

Piperazine derivatives have no residual effect. This means that a single administration will kill the parasites present in the host at the time of treatment, but it will not protect against re-infestations. Since it is not effective against larvae in the host tissues outside the gastrointestinal tract, re-treatments may be required to ensure control of certain species.
