What is Noroxin?Noroxin is a type of antibiotic known as a quinolone and is used to treat bacterial infections, such as urinary tract infections, gonorrhea, and prostate infections.
What is the most important information I should know about Noroxin?Fluoroquinolones, like Noroxin, are associated with an increased risk of tendinitis (inflammation or irritation of a tendon) and tendon rupture in all ages. The risk is further increased in older patients usually >60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart, or lung transplants.
The use of Noroxin may cause you to develop a serious allergic reaction that may be fatal. It is important to immediately notify your physician if you develop any type of rash; difficulty breathing; hives; swelling of the lips, tongue, or face; or throat tightening.
Pseudomembranous colitis (an infection of the colon resulting in diarrhea) has been reported with nearly all antibacterial agents, including Noroxin, and may range in severity from mild to life-threatening. Therefore, it is important to tell your doctor if you experience diarrhea during or after treatment with antibacterial agents such as Noroxin.
Stop taking Noroxin and notify your doctor immediately if you experience fainting spells, abnormal heartbeat or heart rhythm changes, seizures, skin rash, a sunburn-like reaction or skin eruption, or changes in sensation and possible nerve damage characterized by pain, burning, tingling, numbness, and weakness.
The safety and efficacy of Noroxin in children, adolescents <18 years old, pregnant women, and nursing mothers have not been established.
Quinolones, including norfloxacin, may worsen the signs of myasthenia gravis (a neuromuscular disorder characterized by fluctuating muscle weakness), leading to difficulty breathing that may be life-threatening.
Your symptoms may improve before the infection is completely treated; however, you should take this medication for the entire length of time prescribed by your doctor.
Who should not take Noroxin?Do not use this medication if you have ever had a severe reaction to an antibiotic known as a fluoroquinolone, are allergic to any of the ingredients in Noroxin, or have had tendinitis or tendon rupture with the use of Noroxin or another fluoroquinolone antibiotic.
What should I tell my doctor before I take the first dose of Noroxin?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Noroxin. Give your doctor your complete medical history, especially if you have tendon problems, central nervous system problems (such as epilepsy), nerve problems, myasthenia gravis, a personal or family history of irregular heartbeat (especially a condition called QTc prolongation), low potassium (hypokalemia), a slow heartbeat called bradycardia, a history of seizures, kidney problems, rheumatoid arthritis (RA) or other history of joint problems, or are pregnant, plan to become pregnant, breastfeeding, or plan to breastfeed.
