Before Using delafloxacin

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 delafloxacin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to delafloxacin 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

Use in children is not recommended. 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 delafloxacin injection in the elderly. However, elderly patients are more likely to have age-related kidney problems, or develop severe tendon disorders (including tendon rupture), especially in those who also take steroid medicines, which may require caution in patients receiving delafloxacin injection.

Breast Feeding

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.

Proper Use of delafloxacin

A nurse or other trained health professional will give you delafloxacin in a medical facility. It is given through a needle placed into one of your veins. Delafloxacin is given slowly, so the needle will have to remain in place for at least an hour.

Delafloxacin comes with a Medication Guide. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

Your doctor may give you a few doses of delafloxacin until your condition improves, and then be switched to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.

Precautions While Using delafloxacin

It is very important that your doctor check your progress while you are receiving delafloxacin to make sure it is working properly. Blood and urine tests may be needed to check for unwanted effects.

Delafloxacin injection may cause inflammation (tendinitis) or tearing of a tendon (the cord that attaches muscles to bones). This can occur while you are using the medicine or after you finish using it. The risk of having tendon problems may be increased if you are over 60 years of age, are using steroid medicines (eg, dexamethasone, prednisolone, prednisone, Medrol®), have severe kidney problems, have a history of tendon problems (eg, rheumatoid arthritis), or if you have received an organ transplant (eg, heart, kidney, or lung). Check with your doctor right away if you have sudden pain or swelling in a tendon (eg, ankle, back of the knee or leg, shoulder, elbow, or wrist), bruise more easily after an injury, or are unable to bear weight or move the affected area. Refrain from exercise until your doctor says otherwise.

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.

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

Delafloxacin injection may worsen myasthenia gravis (severe muscle weakness) in people who already have this condition. Talk to your doctor if you have concerns.

Delafloxacin may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hives, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after you receive delafloxacin.

Delafloxacin injection may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop using delafloxacin. 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.

Delafloxacin injection may cause some people to become dizzy or lightheaded than they are normally. Do not drive or do anything else that could be dangerous until you know how delafloxacin affects you.

If you are a diabetic patient taking diabetes medicine by mouth: Delafloxacin 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, check with your doctor right away.

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

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
