There are various methods of intaking Hydroxyzine. One can opt for tablets, injections, or solutions. Whatever the way is, the main job is to get into the bloodstream and fight off the infecting pathogens in the body.

The effectiveness of Hydroxyzine remains for some time in the body. Once the symptoms for the ailment reduce, the remnants of Hydroxyzine slowly leave the body. After about 27 hours, the remnants of Hydroxyzine will get flushed out of the system completely.

  • The primary reason behind the span for which any medicine stays in the system is its half-life. The great the half-life, the more time it takes for the antidote to get flushed out of the system. 
  • Another factor is the dosage of Hydroxyzine that a person intakes. The longer the dosage, the longer Hydroxyzine will stay in the system. If the dosage is high, so will be the consumption of the medicine. Hence the duration of the elimination is longer too.
  • How the Hydroxyzine gets ingested will also play an imminent role in the length of time for it to be detectable. The detection period of traces is lesser if the medicine gets administered into the body via injections when compared to tablets.
  • A person’s metabolism rate is a defining factor of how long Hydroxyzine will stay in the system. People who usually have high BMRs will experience a shorter period of detection and vice-versa.
