Before taking Floxin (Ofloxacin Oral)

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of ofloxacin in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of ofloxacin in the elderly. However, elderly patients are more likely to have age-related heart or kidney problems, or develop severe tendon problems (including tendon rupture), which may require caution and an adjustment in the dose for patients receiving ofloxacin.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

It is very important that your doctor check your progress while you are using this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.

If your symptoms do not improve within a few days, or if they become worse, check with your doctor.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention.

Check with your doctor right away if you have dark urine, clay-colored stools, abdominal or stomach pain, or yellow eyes or skin. These maybe symptoms of a serious liver problem.

Ofloxacin may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop using this medicine. Do not take any medicine to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.

Tell your doctor right away if you start having numbness, tingling, or burning pain in your hands, arms, legs, or feet. These may be symptoms of a condition called peripheral neuropathy.

Ofloxacin may rarely cause inflammation or even tearing of a tendon (the cord that attaches muscles to bones). The risk of having tendon problems may be increased if you are over 60 years of age, using steroid medicines (eg, dexamethasone, prednisolone, prednisone, or Medrol®), have severe kidney problems, have a history of tendon problems (eg, rheumatoid arthritis), or have received an organ (eg, heart, kidney, or lung) transplant. If you get sudden pain or swelling in a tendon after exercise (eg, in the ankle, back of the knee or leg, shoulder, elbow, or wrist), check with your doctor right away. Refrain from exercise until your doctor says otherwise.

For patients with an abnormally slow heartbeat or low potassium levels in the blood, ofloxacin may increase your risk of having a fast, slow, or irregular heartbeat. Call your doctor right away if you feel that your heart is not beating normally.

Tell your doctor right away if you have any of the following symptoms while using this medicine: convulsions, feeling anxious, confused, or depressed, seeing, hearing, or feeling things that are not there, severe headache, trouble sleeping, or unusual thoughts or behaviors.

Some people who take ofloxacin may become more sensitive to sunlight than they are normally. Exposure to sunlight, even for brief periods of time, may cause severe sunburn, or skin rash, redness, itching, or discoloration. When you begin using this medicine:

Stay out of direct sunlight, especially between the hours of 10:00 AM and 3:00 PM, if possible.

Wear protective clothing, including a hat and sunglasses.

Apply a sun block product that has a sun protection factor (SPF) of at least 15. Some people may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your doctor.

Do not use a sun lamp or tanning bed or booth.

If you have a severe reaction from the sun, check with your doctor.

Ofloxacin may cause some people to become dizzy, lightheaded, drowsy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert. If these reactions are especially bothersome, check with your doctor.

For diabetic patients taking insulin or oral medicine: Ofloxacin may cause hypoglycemia (low blood sugar) in some patients. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people may feel different symptoms of low blood sugar. If you experience symptoms of low blood sugar, stop taking ofloxacin and check with your doctor right away:

Symptoms of low blood sugar can include: Anxious feeling, behavior change similar to being drunk, blurred vision, cold sweats, confusion, cool pale skin, difficulty in concentrating, drowsiness, excessive hunger, headache, nausea, nervousness, rapid heartbeat, shakiness, or unusual tiredness or weakness.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine.
