What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. This medicine is intended to be used in addition to a healthy diet and appropriate exercise. The best results are achieved this way. Do not increase or in any way change your dose without consulting your doctor or health care professional.

Do not take this medicine within 6 hours of bedtime. It can keep you from getting to sleep. Avoid drinks that contain caffeine and try to stick to a regular bedtime every night.

Do not stop taking this medicine suddenly. This increases the risk of seizures.

This medicine can decrease sweating and increase your body temperature. Watch for signs of deceased sweating or fever. Avoid extreme heat, hot baths, and saunas. Be careful about exercising, especially in hot weather. Contact your health care provider right away if you notice a fever or decrease in sweating.

You should drink plenty of fluids while taking this medicine. If you have had kidney stones in the past, this will help to reduce your chances of forming kidney stones.

If you have stomach pain, with nausea or vomiting and yellowing of your eyes or skin, call your doctor immediately.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may increase dizziness and drowsiness. Avoid alcoholic drinks.

This medicine may affect blood sugar levels. If you have diabetes, check with your doctor or health care professional before you change your diet or the dose of your diabetic medicine.

Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for sudden changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of treatment or after a change in dose, call your health care professional.

If you notice blurred vision, eye pain, or other eye problems, seek medical attention at once for an eye exam.

This medicine may increase the chance of developing metabolic acidosis. If left untreated, this can cause kidney stones, bone disease, or slowed growth in children. Symptoms include breathing fast, fatigue, loss of appetite, irregular heartbeat, or loss of consciousness. Call your doctor immediately if you experience any of these side effects. Also, tell your doctor about any surgery you plan on having while taking this medicine since this may increase your risk for metabolic acidosis.
