Gave my 50lb dog Capstar, but he ran around frantically after—should I be concerned?

I gave my 50-pound dog Capstar this morning to tackle his flea problem, but not long after, he started running around the house frantically. I've never seen him so restless and hyperactive before, and it's been going on for a while now. Is this a normal reaction to the medication, or should I be concerned about his behavior?

Answer

Your dog’s hyperactive behavior after taking Capstar can be concerning, but it is generally a temporary reaction. Some dogs can exhibit increased activity as the fleas become more active before dying.

  • Increased activity is a known side effect of Capstar.
  • The behavior is typically temporary and should subside on its own.
  • Monitor your dog for any other unusual symptoms.

Capstar is an effective oral medication used to treat flea infestations. It's known to act rapidly, and as fleas become more active before they die, some dogs may also show a temporary increase in activity or restlessness. This reaction usually passes within a few hours. However, it's important to observe your dog for any additional symptoms or if the hyperactivity persists for an extended period.
