Nitenpyram in Capstar, an oral flea control product, is approved for use in cats and dogs over 4 weeks of age and 2 pounds of body weight. Nitenpyram starts killing adult fleas that are on the pet within 30 minutes. The peak effect after administering the medication is about 3 hours for the dog and 4 hours for the cat. It will be very useful in certain circumstances such as prior to surgery, and after boarding, or grooming. It will also help prevent pets from bringing fleas home from shows, trials, or trips to the park. The pet could be given the pill before leaving for the park or before heading home from a distant show. Any fleas on the pet will be dead within several hours. It will not work for on-going control as the medication is out of the pet's system within 24 hours.
