Levodopa (Systemic)

Brand name(s): Atamet

Proper Use of This Medicine

Since protein may interfere with the body's response to levodopa, high protein diets should be avoided. Intake of normal amounts of protein should be spaced equally throughout the day, or taken as directed by your doctor.

For patients taking levodopa by itself:

• Pyridoxine (vitamin B ₆) has been found to reduce the effects of levodopa when levodopa is taken by itself. This does not happen with the combination of carbidopa and levodopa. If you are taking levodopa by itself, do not take vitamin products containing vitamin B 6 during treatment, unless prescribed by your doctor.
• Large amounts of pyridoxine are also contained in some foods such as bananas, egg yolks, lima beans, meats, peanuts, and whole grain cereals. Check with your doctor about how much of these foods you may have in your diet while you are taking levodopa. Also, ask your health care professional for help when selecting vitamin products.

At first, levodopa may be taken with a meal or a snack, so that any effects like stomach upset will be lessened. Later, as your body becomes accustomed to the medicine, it should be taken on an empty stomach so that it works better. Be sure to talk to your doctor about the best time for you to take this medicine.

Take this medicine only as directed. Do not take more or less of it, and do not take it more often than your doctor ordered.

For patients taking carbidopa and levodopa extended-release tablets:

• Swallow the tablet whole without crushing or chewing, unless your doctor tells you not to. If your doctor tells you to, you may break the tablet in half.

Some people must take this medicine for several weeks or months before full benefit is received. Do not stop taking it even if you do not think it is working. Instead, check with your doctor.
