Expel-P is a levamisole HCL-based medication that is effective in safely and effectively deworming ornamental fish. It also acts as an immunostimulant agent and is effective against many internal parasites, especially nematodes, when used as directed. Additionally, it works as a coral dip for treating flatworms and pest nudibranchs. It does not treat Cestodes (tapeworms) or Trematodes (flukes).
