LEVOFLOXACIN - ORAL
COMMON BRAND NAME(S): Levaquin
This medication is a quinolone antibiotic used to treat a wide variety of bacterial infections (e.g., urinary tract infections, skin infections, respiratory tract infections).
How To Use
Take by mouth, usually once daily with or without food, or as directed by your doctor. Drink plenty of fluids while taking this medication unless your doctor directs you otherwise. Take this medication 2 hours before or 2 hours after taking any medications containing magnesium or aluminum. Some examples include quinapril, didanosine, vitamins/minerals, and antacids. Sucralfate, bismuth subsalicylate, iron, and zinc are also included. These medications bind with ofloxacin preventing its full absorption. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at the same time of day or night. Continue to take this medication until the full prescribed amount is finished even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow resulting in a relapse of the infection.
Nausea, trouble sleeping, diarrhea, vomiting, change in taste, headache or dizziness may occur. If these symptoms persist or become severe, inform your doctor or pharmacist promptly. Tell your doctor immediately if any of these unlikely but serious side effects occur: "sunburn" (sun sensitivity), joint/muscle/tendon pain or swelling, vaginal discomfort, abdominal pain, vision changes. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: seizures, mental/mood changes, chest pain, irregular heartbeat, restlessness, confusion, change in amount of urine, yellowing eyes/skin. Use of this medication for prolonged or repeated periods may result in oral thrush, or a new yeast infection (e.g., oral or vaginal fungal infection). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge or other new symptoms. An allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of an allergic reaction include: rash, itching, swelling, severe dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
