From the Guidelines
Yes, Sinemet (carbidopa-levodopa) can cause dizziness as a common side effect. This medication, which combines carbidopa and levodopa, is primarily used to treat Parkinson's disease symptoms by increasing dopamine levels in the brain. Although the provided evidence does not directly mention Sinemet causing dizziness, it discusses the side effects of levodopa, a component of Sinemet, and other medications that can cause dizziness, such as carbamazepine 1. Dizziness occurs in approximately 20-30% of patients taking similar medications and may be more pronounced when starting treatment, increasing dosage, or taking it on an empty stomach. The dizziness is often related to orthostatic hypotension (a drop in blood pressure when standing up) caused by the medication's effect on blood vessel regulation. Patients can minimize this side effect by rising slowly from sitting or lying positions, staying well-hydrated, and taking Sinemet with food unless otherwise directed by their healthcare provider. If dizziness becomes severe or persistent, patients should not discontinue the medication abruptly but should consult their healthcare provider, who may adjust the dosage, recommend taking smaller doses more frequently throughout the day, or prescribe additional medications to manage this side effect.
Some key points to consider when taking Sinemet include:
- Monitoring for side effects such as nausea, vomiting, abdominal pain, dyspepsia, constipation, weight decrease, dry mouth, diarrhea, anorexia, and GI disorders 1
- Being aware of the potential for metabolic effects, including changes in lipid and carbohydrate metabolism, and the possible induction of glucose intolerance 1
- Considering the potential for hyperhomocysteinemia and the importance of vitamin B status, particularly folate, vitamin B12, and vitamin B6 1
- Recognizing that dizziness can be a common side effect of medications like carbamazepine, which may be used in conjunction with or as an alternative to Sinemet 1
It is essential to follow the healthcare provider's guidance and recommendations to minimize side effects and ensure the best possible outcome when taking Sinemet.

From the Research
Sinemet and Dizziness
- The provided studies do not directly address the question of whether Sinemet (carbidopa-levodopa) can cause dizziness 3, 4, 5, 6, 7.
- However, it is known that Parkinson's disease, which Sinemet is used to treat, can cause balance and coordination problems, which may lead to dizziness 4.
- The studies focus on the efficacy and complications of Sinemet in treating Parkinson's disease, such as fluctuations, dyskinesias, and loss of efficacy 5, 6.
- One study mentions that patients on long-term levodopa therapy may experience adverse effects, but dizziness is not specifically mentioned 5.
- Another study discusses the long-duration action of levodopa, but does not address potential side effects like dizziness 7.
Potential Side Effects of Sinemet
- While the studies do not directly mention dizziness as a side effect of Sinemet, they do discuss other potential complications and adverse effects 3, 4, 5, 6, 7.
- Patients taking Sinemet may experience nausea, vomiting, and other gastrointestinal symptoms, which could potentially contribute to dizziness 3.
- However, without direct evidence, it is unclear whether Sinemet can cause dizziness 3, 4, 5, 6, 7.
