What Should I Do If I Forget a Dose of Gemifloxacin?

If you forget to take your gemifloxacin dose, just take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the one you missed and continue with your regular schedule. Do not take a double dose.

How Does It Work?

Gemifloxacin works to treat bacterial infections by killing the bacteria that cause the infections. Specifically, gemifloxacin interferes with two bacterial enzymes called topoisomerase IV and DNA gyrase. These enzymes are necessary for the bacteria to copy and repair DNA, which are critical steps needed for the bacteria to multiply.

When and How to Use This Medication

Some general considerations to keep in mind during treatment with gemifloxacin include the following:
  • Gemifloxacin comes in tablet form. It is usually taken once a day.
  • This medication can be taken with or without food. Take it with a glass of water.
  • Try to take gemifloxacin at the same time each day to maintain an even level in your blood.
  • Swallow gemifloxacin tablets whole -- do not crush or chew them. Tell your healthcare provider if you cannot swallow the tablets. You may break the tablets in half (along the break lines), if necessary.
  • Make sure you drink plenty of fluids to stay well hydrated during gemifloxacin treatment.
  • Gemifloxacin is an antibiotic used to treat bacterial infections. It will not treat infections caused by viruses, such as the common cold or flu.
  • You should start to feel better within a couple of days of treatment. However, this does not mean your infection is gone. Make sure you finish the entire course of this medicine. Stopping it too early may cause your symptoms to return or lead to antibiotic resistance.
  • For the medication to work properly, it must be used as prescribed.
