Our pharmacists’ bottom line

This is the first medication approved as an Integrase Inhibitor (InSTI), so it may be a great, but somewhat expensive, option for people who have already tried other drugs and need another option.

  • If having difficulty swallowing the tablet, consider the chewable tablet or oral suspension.
  • Only one tablet taken two times a day.
  • Can be used for kids 4 weeks and older.
  • May be helpful if other HIV drugs have stopped working since Isentress works differently than most HIV drugs.
  • Tablets, chewable tablets, and the oral suspension all have different doses, so talk to your doctor if you want to switch from one to another.
  • The oral suspension has to be taken within 30 minutes of mixing it.
  • Avoid taking antacids that contain aluminum and/or magnesium while taking Isentress.
  • Let your doctor know right away if while taking Isentress you begin to feel unexplained muscle pain.
