Drug Interaction Checker

Enteral feedings, such as Ensure or Sustacal, may decrease the actions of Levofloxacin, by decreasing its absorption from the stomach. Take Enteral feedings at least 2 hours before or 2 hours after Levofloxacin to limit an interaction. Let your health care provider know you are using Enteral Feedings. Contact your health care provider if your condition being treated by Levofloxacin does not improve.

Food may decrease the actions of Levofloxacin (Levaquin). It is best to take Levofloxacin on an empty stomach, 2 hours before or 2 hours after a meal. Foods high in calcium and iron may decrease the actions of Quinolone antibiotics such as Levaquin. Dairy products or calcium-fortified juices may decrease the effectiveness of these antibiotics, which can reduce the drug's ability to cure your infection. Avoid taking these foods or beverages within 4 hours before or 2 hours after your Levaquin dose. Discuss with your health care provider other foods that may affect Levaquin.

Although an interaction is possible, these drugs are often used together. Side effects from Caffeine may get worse if you take Levofloxacin. Too much Caffeine can cause effects like nausea, nervousness, or sleeplessness. You may need to limit your Caffeine intake. Common foods and beverages containing caffeine include coffee, teas, colas and chocolate. Many non-prescription drugs and diet aids may also contain caffeine.
