The red, capsule-shaped pill with the imprint 83 has been identified as Levofloxacin 500 mg. It is supplied by Torrent Pharmaceuticals Limited. 83 pills are used to treat certain infections such as pneumonia, and kidney, prostate (a male reproductive gland), and skin infections. 83 pill is also used to prevent anthrax (a serious infection that may be spread on purpose as part of a bioterror attack) in people who may have been exposed to anthrax germs in the air, and treat and prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack.
In addition, 83 pills may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and certain types of urinary tract infections if there are other treatment options available. Levofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections. Antibiotics such as 83 pills will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
How to use 83 pills
Read the 83 pills Medication Guide provided by your pharmacist before you start taking 83 pills and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually once daily with or without food. Drink plenty of fluids while taking this medication unless otherwise directed by your doctor.
Take 83 pills at least 2 hours before or 2 hours after taking other products that may make it work less well. Examples include quinapril, sucralfate, vitamins/minerals (including iron, zinc), and products that contain magnesium, aluminum, or calcium (such as antacids, didanosine solution, calcium-enriched juice), among others. Ask your pharmacist about all the products you take.
The dosage and length of treatment are based on your medical condition and response to treatment. In children, the dosage is also based on weight.
For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time every day.
Continue to take 83 pills until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection. Tell your doctor if your condition lasts or gets worse.
