HOW TO USE: Shake the bottle well before each dose. Take this medication by mouth usually every 6 or 12 hours, or as directed by your doctor. You may take this medicine with food if stomach upset occurs. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. Continue to take this medication until the full-prescribed amount is finished even if symptoms disappear after a few days. Stopping this medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Inform your doctor if your condition persists or worsens.

SIDE EFFECTS: Stomach upset, headache, fatigue, dizziness, or diarrhea may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Tell your doctor immediately if any of these unlikely but serious side effects occur: mental/mood changes. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: stomach/abdominal pain, persistent nausea/vomiting, yellowing eyes or skin, dark urine, new signs of infection (e.g., persistent sore throat or fever), easy bruising/bleeding, change in the amount of urine. This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to a resistant bacteria. This condition may occur while receiving therapy or even weeks after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have the following symptoms because such products may make them worse. Tell your doctor immediately if you develop persistent diarrhea, abdominal or stomach pain/cramping, or blood/mucus in your stool. Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (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. A serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching, swelling, severe dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
