What happens if I miss a dose (Raxar)?
Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take only your next regularly scheduled dose. Do not take a double dose of this medication unless otherwise directed by your doctor.
What happens if I overdose (Raxar)?
Seek emergency medical attention.
The most common symptom of a grepafloxacin overdose is irregular or slow heartbeats.
What should I avoid while taking grepafloxacin (Raxar)?
Avoid prolonged exposure to sunlight. Grepafloxacin increases the sensitivity of the skin to sunlight, and a severe sunburn may result. If sun exposure is unavoidable, wear protective clothing and use sunscreen. Call your doctor if you experience severe burning, redness, itching, rash, or swelling after exposure to the sun.
Use caution when driving, operating machinery, or performing other hazardous activities. Grepafloxacin may cause dizziness. If you experience dizziness, avoid these activities.
What other drugs will affect grepafloxacin (Raxar)?
Do not take antacids that contain magnesium or aluminum (e.g., Tums or Rolaids), the ulcer medicine sucralfate (Carafate), or vitamin or mineral supplements that contain iron or zinc for a minimum of 4 hours before or 4 hours after a dose of grepafloxacin. Taking antacids, sucralfate, or vitamin or mineral supplements too close to a dose of grepafloxacin can greatly decrease the effects of the antibiotic.
Do not take grepafloxacin without first talking to your doctor if you are taking any of the following drugs:
- the heart medicines amiodarone (Cordarone), disopyramide (Norpace), quinidine (Cardioquin, Quinidex, Quinaglute, others), procainamide (Procan SR, Pronestyl), sotalol (Betapace), and bepridil (Vascor);
- terfenadine (Seldane, Seldane-D) or astemizole (Hismanal);
- a tricyclic antidepressant including amitriptyline (Elavil, Endep), amoxapine (Asendin), imipramine (Tofranil), nortriptyline (Pamelor), doxepin (Sinequan), and others;
- a phenothiazine including chlorpromazine (Thorazine), fluphenazine (Prolixin), perphenazine (Trilafon), mesoridazine (Serentil), thioridazine (Mellaril), and others;
- erythromycin (E-Mycin, Ery-Tab, E.E.S., others); or
- cisapride (Propulsid).
Grepafloxacin and the drugs listed above may affect the rhythm of your heartbeats. You may not be able to take grepafloxacin, or you may require a dosage adjustment or special monitoring during treatment if you are taking any of the medicines listed above.

- insulin or an oral diabetes medication such as glipizide (Glucotrol), glyburide (Micronase, Diabeta, Glynase), and others; or
- a nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen (Motrin, Advil, Nuprin, others), naproxen (Aleve, Naprosyn, Anaprox), ketoprofen (Orudis KT, Orudis, Oruvail), and others.
