Penetrex Patient Information including If I Miss a Dose

What happens if I miss a dose (Penetrex)?

Take the missed dose up to 2 hours late. If more than 2 hours have passed since the missed dose, skip it and take 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 (Penetrex)?

Seek emergency medical attention if an overdose is suspected.

The most common symptom of a enoxacin overdose is seizures.

What should I avoid while taking enoxacin (Penetrex)?

Avoid excessive exposure to sunlight. Enoxacin increases the sensitivity of the skin to sunlight, and a severe sunburn may result. Wear protective clothing and sunscreen if sun exposure is unavoidable. Call your doctor if you experience severe burning, redness, swelling, blistering, itching, or a rash after exposure to sunlight.

Avoid excessive intake of caffeine-containing products such as coffee, tea, colas, and chocolate.

Use caution when driving, operating machinery, or performing other hazardous activities. Enoxacin may cause dizziness. If you experience dizziness, avoid these activities.

What other drugs will affect enoxacin (Penetrex)?

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 8 hours before or 2 hours after a dose of enoxacin. Taking antacids, sucralfate, or vitamin or mineral supplements too close to a dose of enoxacin can greatly decrease the effects of the antibiotic.

Before taking enoxacin, tell your doctor if you are taking any of the following drugs:

  • bismuth subsalicylate (Pepto-Bismol);
  • theophylline (Theo-Dur, Theolair, Slo-Phyllin, Slo-Bid, Elixophyllin);
  • digoxin (Lanoxin);
  • warfarin (Coumadin);
  • probenecid (Benemid);
  • insulin or an oral diabetes medication such as glipizide (Glucotrol), glyburide (Micronase, Diabeta, Glynase), and others;
  • a nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen (Motrin, Advil, Nuprin, others), naproxen (Aleve, Naprosyn, Anaprox), ketoprofen (Orudis KT, Orudis, Oruvail), and others; or
  • cyclosporine (Neoral, Sandimmune).

You may not be able to take enoxacin, 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 enoxacin. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.

Where can I get more information?

Your pharmacist has additional information about enoxacin written for health professionals that you may read.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
