Important safety information:
- Tequin may cause dizziness, drowsiness, or changes in vision. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Tequin. Using Tequin alone, with certain other medicines, or with alcohol may lessen your ability to drive or perform other potentially dangerous tasks.
- Tequin is effective only against bacteria. It is not effective for treating viral infections (eg, the common cold).
- It is important to use Tequin for the full course of treatment. Failure to do so may decrease the effectiveness of Tequin and may increase the risk that the bacteria will no longer be sensitive to Tequin and will not be able to be treated by this or certain other antibiotics in the future.
- Long-term or repeated use of Tequin may cause a second infection. Your doctor may want to change your medicine to treat the second infection. Contact your doctor if signs of a second infection occur.
- If severe diarrhea, stomach pain/cramps, or bloody stools occur, contact your doctor immediately. This could be a symptom of a serious side effect requiring immediate medical attention. Do not treat diarrhea without consulting your doctor.
- Tequin may cause increased sensitivity to the sun. Avoid exposure to the sun, sunlamps, or tanning booths until you know how you react to Tequin. Use a sunscreen or wear protective clothing if you must be outside for a prolonged period.
- Tequin may cause low blood sugar (eg, increased heartbeat, headache, chills, sweating, tremor, increased hunger, changes in vision, nervousness, weakness, dizziness, drowsiness, fainting) or high blood sugar (eg, thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, fruity breath odor). If these symptoms occur, tell your doctor immediately.
- Lab tests, including liver function, kidney function, and complete blood cell counts, may be performed to monitor your progress or to check for side effects. Be sure to keep all doctor and lab appointments.
- Use Tequin with caution in the ELDERLY because they may be more sensitive to its effects, especially blood sugar changes.
