Tell your doctor immediately if you notice worsening involuntary muscle movements/spasms, greatly increased eye blinking/twitching, or mental/mood changes (e.g., confusion, depression, hallucinations, thoughts of suicide). Your doctor may decide to lower your levodopa dose.
Dizziness, nausea, and vomiting may occur. If any of these effects persist or worsen, contact your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she 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 carbidopa 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, including up to 1 year after starting the medication. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in 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.
Tell your doctor immediately if any of these unlikely but serious side effects occur: fainting, unusual strong urges (such as increased gambling, increased sexual urges).
Tell your doctor immediately if any of these rare but very serious side effects occur: easy bleeding/bruising, signs of infection (e.g., fever, persistent sore throat), tingling of the hands/feet, vision changes (e.g., blurred/double vision).
Seek immediate medical attention if any of these rare but very serious side effects occur: chest pain, seizures, vomit that looks like coffee grounds, black/tarry stools.
Abruptly stopping or reducing the dose of this medication may rarely cause a serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, unusual muscle stiffness, severe confusion, sweating, fast/irregular heartbeat, rapid breathing.
For males, in the very unlikely event you have a painful or prolonged erection (lasting more than 4 hours), stop using this drug and seek immediate medical attention or permanent problems could occur.
A very serious allergic reaction is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
