What Is Oflomac (Floxin)?
Oflomac is an antibiotic drug used to treat bacterial infections.
It's commonly used as an eye drop to treat conjunctivitis (pink eye) and corneal ulcers.
The tablet form of Oflomac is prescribed for various bacterial infections, such as pneumonia, bronchitis, urinary tract infections (UTI), gastrointestinal infections, prostate infections caused by E. coli, skin infections, and some sexually transmitted diseases.
It may also be used to prevent or treat anthrax or plague in certain people.
The medicine also comes as an ear drop to treat middle and outer ear infections.
Oflomac belongs to a class of drugs called fluoroquinolone antibiotics. It works by killing harmful bacteria that cause infection.
The U.S. Food and Drug Administration (FDA) approved Oflomac in 1990. It's sold under different brand names and manufactured by various companies.
How should this medicine be used?
Oflomac 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 Oflomac. Take Oflomac 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 Oflomac 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 Oflomac. If your symptoms do not improve or if they get worse, call your doctor.
Take Oflomac until you finish the prescription, even if you feel better. Do not stop taking Oflomac 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 Oflomac too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Safety and effectiveness in infants below the age of one year have not been established. Quinolones, including Oflomac, have been shown to cause arthropathy in immature animals after oral administration; however, topical ocular administration of Oflomac to immature animals has not shown any arthropathy. There is no evidence that the ophthalmic dosage form of Oflomac has any effect on weight bearing joints.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long term studies to determine the carcinogenic potential of Oflomac have not been conducted.
Oflomac was not mutagenic in the Ames test, in vitro and in vivo cytogenic assay, sister chromatid exchange assay (Chinese hamster and human cell lines), unscheduled DMA synthesis (UDS) assay using human fibroblasts, the dominant lethal assay, or mouse micronucleus assay. Oflomac was positive in the UDS test using rat hepatocyte, and in the mouse lymphoma assay.
In fertility studies in rats, Oflomac did not affect male or female fertility or morphological or reproductive performance at oral dosing up to 360 mg/kg/day (equivalent to 4000 times the maximum recommended daily ophthalmic dose).

Eye infections are a common cause of conjunctivitis. In conjunctivitis, your eye becomes inflamed, feels gritty, and may water more than usual. The white of your eye may look red, and your eyelids may become swollen and stuck together with a discharge when you wake up in the morning. Only one eye may be infected to begin with, but it often spreads to both eyes. Most cases of infective conjunctivitis clear within a week or so without treatment. For more severe infections, or for infections which do not clear on their own, an antibiotic eye drop such as Oflomac can be used.
Is Oflomac safe to take while pregnant or breastfeeding?
Oflomac should be avoided during pregnancy because it is secreted in breast milk and can cause adverse events in the infant.
Oflomac should be avoided in nursing mothers, as safe use has not been established.
Symptoms of an Oflomac overdose may include:
- Hot and cold flashes
- Slurred speech
- Numbness or swelling of the face
If you suspect an overdose, contact a poison control center or emergency room immediately.
You can get in touch with a poison control center at 800-222-1222.
