Capstar FAQ


What is Capstar and how does it work?


Capstar is a brand of oral flea medication that is used to rapidly kill fleas on dogs and cats. The active ingredient in Capstar is nitenpyram, an insecticide that targets the nervous system of fleas. After ingestion, nitenpyram is quickly absorbed into the bloodstream, and when fleas feed on the treated animal, they are rapidly killed within 30 minutes.


What types of pets can take Capstar?


Capstar is safe for use on dogs and cats, including puppies and kittens over 4 weeks of age, and weighing at least 2 pounds. However, it is important to always read the label and instructions carefully before administering any medication to your pet.


How often should Capstar be given to pets?


Capstar is a short-term treatment that is designed to provide immediate relief from flea infestations. It can be given as often as once a day but no more than once every 24 hours. However, it is important to note that Capstar does not provide long-term flea prevention, and additional flea control measures may be necessary to keep your pet flea-free.


Are there any side effects of Capstar?


Capstar is generally considered safe for use in pets, and side effects are rare. However, some pets may experience mild side effects such as vomiting, diarrhea, lethargy, or itching. These symptoms are usually mild and temporary and usually resolve independently within a few hours.


Can Capstar be used alongside other flea medications?


Capstar can be used in conjunction with other flea medications, but it is important to consult with your veterinarian before using multiple flea treatments at the same time. It is also important to follow the instructions carefully and never use more than the recommended dose of any flea medication.


Is Capstar effective against all flea life stages?


Capstar is only effective against adult fleas and does not kill flea eggs, larvae, or pupae. Therefore, it is important to use additional flea control measures, such as flea sprays or topical treatments, to target these other stages of the flea life cycle and prevent re-infestations.
