Onexacin Ophthalmic Dosage
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not use this medicine while wearing contact lenses. Onexacin ophthalmic may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.
Wash your hands before using the eye drops.
To apply the eye drops:
- Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
- Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
- Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
- Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
When treating a corneal ulcer, you may need to wake from sleep every 4 to 6 hours to use the medication. Follow your doctor's dosing instructions very carefully. You may notice a whitish buildup on the ulcer. This is a sign that the medication is working and is not a harmful effect. This buildup should clear within a few days or weeks of treatment.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
Store at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.
An overdose of Onexacin ophthalmic is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together including: tendinitis and tendon rupture, peripheral neuropathy, and central nervous system (CNS) effects.
Discontinue the drug immediately and avoid use of systemic fluoroquinolones in patients who experience any of these serious adverse reactions.
May exacerbate muscle weakness in patients with myasthenia gravis; avoid fluoroquinolones with known history of myasthenia gravis.
Serious adverse effects and limitations-of-use:
- Both oral and injectable fluroquinolones are associated with disabling side effects involving tendons, muscles, joints, nerves and the central nervous system.
- These side effects can occur hours to weeks after exposure to fluoroquinolones and may potentially be permanent.
- Because the risk of these serious side effects generally outweighs the benefits for patients with acute bacterial sinusitis, acute exacerbation of chronic bronchitis, and uncomplicated urinary tract infecitons (UTIs), that fluoroquinolones should be reserved for use in patients with these conditions who have no alternative treatment options.
- For some serious bacterial infections, including anthrax, plague, and bacterial pneumonia among others, the benefits of fluoroquinolones outweigh the risks and it is appropriate for them to remain available as a therapeutic option.
This medication contains Onexacin. Do not take Floxin if you are allergic to Onexacin or any ingredients contained in this drug.
Keep out of reach of children. In case of overdose, get medical help or contact a Poison Control Center immediately.

How should this medicine be used?
Onexacin comes as a tablet to take by mouth. It is usually taken with or without food twice a day for 3 days to 6 weeks. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to take Onexacin. Take Onexacin at around the same times every day and try to space your doses 12 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Onexacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
You should begin to feel better during the first few days of your treatment with Onexacin. If your symptoms do not improve or if they get worse, call your doctor.
Take Onexacin until you finish the prescription, even if you feel better. Do not stop taking Onexacin without talking to your doctor unless you experience certain serious side effects that are listed in the IMPORTANT WARNING and SIDE EFFECT sections. If you stop taking Onexacin too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
