During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Levodopa passes into breast milk in small amounts and may affect how much milk you make. It is unknown if carbidopa passes into breast milk. Consult your doctor before breastfeeding. Side EffectsDizziness, lightheadedness, nausea, vomiting, loss of appetite, trouble sleeping, unusual dreams, or headache may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. This medication may cause saliva, urine, or sweat to turn a dark color. This effect is harmless, but your clothes may be stained. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Some people taking this medication have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with carbidopa/levodopa even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or do other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
