Safe

• CAPSTAR has no labeled side effects.
• CAPSTAR can be used along with other flea-control products and medications commonly dispensed by veterinarians, including heartworm preventives, deworming products, shampoos and antibiotics.
• CAPSTAR is eliminated from a pet’s system rapidly, which enhances safety and reduces the opportunity for fleas to develop resistance.
• You can give CAPSTAR to puppies and kittens as young as 4 weeks old as long as they weigh at least 2 pounds
