The nurse is preparing to administer levofloxacin (Levaquin) 400 mg orally to a client with a urinary tract infection. Which statement by the client requires further teaching by the nurse?

  • “I will need to wear sunscreen if I am outdoors.”
  • “I need to finish all the medication, even if my symptoms go away.”
  • “I should take my antacid right before my pill so I don’t get heartburn.”
  • “I need to check my pulse twice daily and call my doctor if I have new-onset irregular heartbeats.”
Number 3 is correct.
Antacids should not be taken within 2 hours of Levaquin because they interfere with absorption of the drug, especially if they contain aluminum or magnesium. Levaquin, along with many other antibiotics, increases sun sensitivity. The client should avoid going outdoors or wear sunscreen while on therapy. Taking the complete course of medication prevents rebound infections and antibiotic resistance. Clients should be taught how to take their pulse and report any new-onset irregular heartbeats, as fluoroquinolones may cause serious dysrhythmias.
