Capstar is an oral flea treatment designed to quickly kill adult fleas in dogs and puppies 4 weeks of age and older and weighing at least 2 lbs. This convenient and easy-to-dose tablet offers rapid relief from active flea infestations.
Administered orally, Capstar starts killing adult fleas within just 30 minutes of dosing and works to quickly reduce flea infestations on dogs for up to 24 hours. It is commonly used to treat existing flea problems and can be given when immediate flea control is needed.
It eliminates fleas before they can lay eggs and develop an infestation. Because it acts quickly and safely, Capstar is often used alongside long-term flea prevention products as part of a comprehensive flea control strategy. It can be given daily if needed to control flea infestations.
The treatment is also suitable for pregnant and nursing dogs. Choose Capstar Flea Tablets for short-term and fast relief from the nuisance of fleas and save them from discomfort.
Capstar is formulated with nitenpyram, a fast-acting insecticide, as the key ingredient. Nitenpyram targets adult fleas by attacking their nervous system. After oral administration, nitenpyram is rapidly absorbed into the dog’s bloodstream. When fleas feed on the treated dog, they ingest the active ingredient and are quickly eliminated. Capstar kills fleas quickly after administration and stops fleas from establishing an infestation.
