Zagam Patient Information including If I Miss a Dose

What happens if I miss a dose (Zagam)?

Take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose of this medication unless otherwise directed by your doctor.

What happens if I overdose (Zagam)?

Seek emergency medical attention.

The most common symptom of a sparfloxacin overdose is irregular or slow heartbeats.

What should I avoid while taking sparfloxacin (Zagam)?

Avoid prolonged exposure to sunlight. Sparfloxacin increases the sensitivity of the skin to sunlight, and a severe sunburn may result. If sun exposure is unavoidable, wear protective clothing and 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. Sparfloxacin may cause dizziness. If you experience dizziness, avoid these activities.

What other drugs will affect sparfloxacin (Zagam)?

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 after a dose of sparfloxacin. Taking antacids, sucralfate, or vitamin or mineral supplements too close to a dose of sparfloxacin can greatly decrease the effects of the antibiotic.

Do not take sparfloxacin 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).

Sparfloxacin and the drugs listed above may affect the rhythm of your heartbeats. You may not be able to take sparfloxacin, or you may require a dosage adjustment or special monitoring during treatment if you are taking any of the medicines listed above.

Drugs other than those listed here may also interact with sparfloxacin. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines, including herbal products.
