If your symptoms do not improve in a few weeks or if they become worse, check with your doctor. It may take several days to weeks for this medicine to work. Do not stop taking this medicine without checking with your doctor. Keep all doctor and laboratory appointments while you are taking this medicine.

This medicine may cause drowsiness or dizziness. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to this medicine. Using this medicine alone, with other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks.

Alcohol, hot weather, exercise, and fever can increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Also sit or lie down at the first sign of dizziness, lightheadedness, or weakness. Do not become overheated in hot weather or during exercise or other activities since risk of heatstroke may be increased.

This medicine may increase your risk of developing diabetes or cause hyperglycemia (high blood sugar), sometimes severe. Symptoms of hyperglycemia include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, weakness, or fruity breath odor. High blood sugar levels can cause serious problems if left untreated. If these symptoms occur, tell your doctor immediately. Before you begin taking any new medicine, either prescription or over-the-counter, check with your doctor or pharmacist.

Caution is advised when using this medicine in the elderly, especially those with dementia related problems, because they may be more sensitive to the effects of this medicine.
